length of a phd thesis

How long is a PhD dissertation? [Data by field]

The final piece of the PhD journey is the PhD dissertation. It takes many years to accumulate enough original and new data to fill out a dissertation to the satisfaction of experts in your field. Interestingly, the PhD dissertation length and content vary significantly based on the field you are studying and the publishing conventions.

A PhD can be anywhere from 50 pages to over 450 pages long. This equates to between about 20,000 words to 100,000 words. Most PhD theses are between 60,000 and 80,000 words long excluding contents, citations and references.

A PhD thesis contains different sections including an introduction, methods, results and discussion, conclusions, further work, and references. Each one of these different sections will vary in length depending on the field of study and your particular topic.

Ultimately, a PhD dissertation should contain as many pages and words as it takes to communicate the results of your multi-year investigation.

It is very rewarding to see your thesis come together as you are writing day after day. When I was writing my PhD dissertation I wrote the sections separately and my heart filled with joy when I finally put them all together and compile them into a single PDF document.

Counting the pages should not be the way to determine a PhD dissertation’s value but it certainly helps when your thesis is starting to look substantial in thickness.

How many pages should a PhD dissertation be?

A PhD dissertation should contain as many pages and words as it takes to outline the current state of your field and provide adequate background information, present your results, and provide confidence in your conclusions. A PhD dissertation will also contain figures, graphs, schematics, and other large pictorial items that can easily inflate the page count.

Here is a boxplot summary of many different fields of study and the number of pages of a typical PhD dissertation in the field. It has been created by Marcus Beck from all of the dissertations at the University of Minnesota.

Typically, the mathematical sciences, economics, and biostatistics theses and dissertations tend to be shorter because they rely on mathematical formulas to provide proof of their results rather than diagrams and long explanations.

On the other end of the scale, English, communication studies, political science, history and anthropology are often the largest theses in terms of pages and word count because of the number of words it takes to provide proof and depth of their results.

At the end of the day, it is important that your thesis gets signed off by your review committee and other experts in the field. Your supervisor will be the main judge of whether or not your dissertation is capable of satisfying the requirements of a PhD in your field.

Can a PhD dissertation be too long?

A PhD thesis should contain enough evidence and discussion to report on the most significant findings of your PhD research.

A PhD dissertation should not contain everything that you have done during your PhD. It should only include the data and information required to convince your PhD examining body that wraps up and tells the full story of particular lines of investigation.

Including random results, thoughts, or superfluous explanation can result in a dissertation that is unfocused. I have heard of music PhD is being described as too verbose and physical sciences PhD dissertations as being unfocused.

Therefore, a PhD thesis can be too long if the information it contains does not form a full and cohesive story.

One of my colleagues during their PhD removed an entire chapter from the thesis after writing it as the supervisor said that it needed more experiments to be a full story. They did not want to spend the next six months gathering the data and simply removed the chapter altogether.

How short can PhD dissertation be?

The shortest PhD dissertations are typically found in mathematics.

George Bernard Danzig was an American mathematical scientist who made contributions to industrial engineering and many other mathematical-related fields. An interesting miscommunication led to 1 of the shortest PhD theses ever.

In 1939 his professor wrote two problems on the blackboard and Danzig thought they were homeless assignments. He stated that they were harder than usual but handed in solutions to the surprise of the professor.

They were, in fact, open mathematical problems in statistics.

His professor said to bind the solution to the two problems together and submit them as his thesis – the total thesis length = 14 pages.

Obviously, most PhD theses and dissertations will be so much longer than that!

My PhD dissertation was 256 pages long. It was full of schematics, diagrams, and tables to demonstrate and communicate my findings.

I would say that most people’s PhD thesis experience will be closer to mine than Prof George Bernard Danzig’s.

Why PhD dissertations are typically so long

PhD dissertations are often over 200 pages long.

One of the primary reasons they are so long is that it is a single document that summarises many years of hard work. Also, summarising the research field to date and making sure that all of your references and citations are included so you avoid plagiarism will bolster the word count of the thesis dramatically.

Here are all of the reasons PhD dissertations tend to be so long.

Many years of work

PhD theses or dissertations contain many years of research and analysis.

In many of my YouTube videos I recommend that a PhD student work towards their PhD thesis by doing at least three hours of focused work every work day.

This amount of work quickly adds up.

Of course, not every bit of work makes it into the PhD dissertation but a lot of it does. It can be difficult to work out what to include or leave out of your thesis.

As a PhD student, I perfected the art of turning one experiment into many different types of grafts and schematics to fully explore the limits of my data. The graphs can take up a lot of space in your PhD thesis and, therefore, bolster the page count significantly.

In depth literature review

One of the most substantial parts of a PhD dissertation is the literature review.

The literature review can take up a huge portion of the early part of your PhD dissertation depending on the amount of data and publications in your field.

Writing an in-depth literature review requires just as much meticulous data analysis and searching as the central part of your dissertation.

Figures and schematics

Some fields end up producing a lot of figures and schematics.

My thesis had many full-page figures of atomic force microscopy experiments with much more explanation on subsequent pages.

As they say, a picture paints a thousand words and a dissertation can really benefit from having many schematics to highlight the important aspects of your findings.

References and citations

The recommended PhD dissertation word count from an institution or university does not include citations, references, or other thesis parts such as summary of abbreviations, table of figures, et cetera.

However, these components of your dissertation can take up many pages and add to the overall thickness of your PhD dissertation.

University formatting rules

University formatting rules will also dictate how you many pages your words take up.

I often get roasted on my YouTube channel for having doublespaced lines and wide margins. Unfortunately, this layout was dictated by my university before printing.

PhD dissertations often end up going into long-term storage and therefore, need to adhere to archival and standardised formatting rules.

Deep in the depths of the University of Newcastle, there is a copy of my thesis on a shelf. The formatting and binding rules mean that my thesis looks like everyone else’s.

Universities will often have their own requirements for PhD dissertation cover colour, quality, and type of paper. Even the quality of the paper can change the thickness of the PhD dissertation significantly.

PhD by publication

It is becoming increasingly common to submit a number of peer-reviewed papers bound together with supplementary information in between instead of a PhD dissertation.

The benefits of this to the researcher and university are:

• More early career peer-reviewed journals for career advancement
• an easier review process – they have already been peer-reviewed
• an early focus on publishing means better research outcomes for the researcher, supervisor, and Department.
• No mad rush at the end to finish a thesis
• continually writing peer-reviewed papers throughout your PhD helps with timely analysis and communication of results

Even though this option has been available to PhD students for a number of years, I have only known a handful of students actually submit their PhD via publication.

Nonetheless, having this option will suit some research fields better than others and lead to a more productive PhD.

Wrapping up

This article has been through everything you need to know about the length of a PhD dissertation and the common lengths of PhD dissertations for various fields.

Ultimately, there is no predefined length of a PhD.

A PhD thesis is as long as it needs to be to convince your examiners that you have contributed significantly enough to an academic field to be awarded the title of Dr of philosophy.

Mathematical and analytical theses tend to be shorter and can be as short as 50 pages (with one of the shortest being only 14 pages long). At the other end of the spectrum, PhD students in anthropology and history tend to produce the longest dissertations.

Embarking on a PhD is “probably the most challenging task that a young scholar attempts to do”, write Mark Stephan Felix and Ian Smith in their practical guide to dissertation and thesis writing. After years of reading and research to answer a specific question or proposition, the candidate will submit about 80,000 words that explain their methods and results and demonstrate their unique contribution to knowledge. Here are the answers to frequently asked questions about writing a doctoral thesis or dissertation.

What’s the difference between a dissertation and a thesis?

Whatever the genre of the doctorate, a PhD must offer an original contribution to knowledge. The terms “dissertation” and “thesis” both refer to the long-form piece of work produced at the end of a research project and are often used interchangeably. Which one is used might depend on the country, discipline or university. In the UK, “thesis” is generally used for the work done for a PhD, while a “dissertation” is written for a master’s degree. The US did the same until the 1960s, says Oxbridge Essays, when the convention switched, and references appeared to a “master’s thesis” and “doctoral dissertation”. To complicate matters further, undergraduate long essays are also sometimes referred to as a thesis or dissertation.

The Oxford English Dictionary defines “thesis” as “a dissertation, especially by a candidate for a degree” and “dissertation” as “a detailed discourse on a subject, especially one submitted in partial fulfilment of the requirements of a degree or diploma”.

The title “doctor of philosophy”, incidentally, comes from the degree’s origins, write Dr Felix, an associate professor at Mahidol University in Thailand, and Dr Smith, retired associate professor of education at the University of Sydney , whose co-authored guide focuses on the social sciences. The PhD was first awarded in the 19th century by the philosophy departments of German universities, which at that time taught science, social science and liberal arts.

How long should a PhD thesis be?

A PhD thesis (or dissertation) is typically 60,000 to 120,000 words ( 100 to 300 pages in length ) organised into chapters, divisions and subdivisions (with roughly 10,000 words per chapter) – from introduction (with clear aims and objectives) to conclusion.

The structure of a dissertation will vary depending on discipline (humanities, social sciences and STEM all have their own conventions), location and institution. Examples and guides to structure proliferate online. The University of Salford , for example, lists: title page, declaration, acknowledgements, abstract, table of contents, lists of figures, tables and abbreviations (where needed), chapters, appendices and references.

A scientific-style thesis will likely need: introduction, literature review, materials and methods, results, discussion, bibliography and references.

As well as checking the overall criteria and expectations of your institution for your research, consult your school handbook for the required length and format (font, layout conventions and so on) for your dissertation.

A PhD takes three to four years to complete; this might extend to six to eight years for a part-time doctorate.

What are the steps for completing a PhD?

Before you get started in earnest , you’ll likely have found a potential supervisor, who will guide your PhD journey, and done a research proposal (which outlines what you plan to research and how) as part of your application, as well as a literature review of existing scholarship in the field, which may form part of your final submission.

In the UK, PhD candidates undertake original research and write the results in a thesis or dissertation, says author and vlogger Simon Clark , who posted videos to YouTube throughout his own PhD journey . Then they submit the thesis in hard copy and attend the viva voce (which is Latin for “living voice” and is also called an oral defence or doctoral defence) to convince the examiners that their work is original, understood and all their own. Afterwards, if necessary, they make changes and resubmit. If the changes are approved, the degree is awarded.

The steps are similar in Australia , although candidates are mostly assessed on their thesis only; some universities may include taught courses, and some use a viva voce. A PhD in Australia usually takes three years full time.

In the US, the PhD process begins with taught classes (similar to a taught master’s) and a comprehensive exam (called a “field exam” or “dissertation qualifying exam”) before the candidate embarks on their original research. The whole journey takes four to six years.

A PhD candidate will need three skills and attitudes to get through their doctoral studies, says Tara Brabazon , professor of cultural studies at Flinders University in Australia who has written extensively about the PhD journey :

• master the academic foundational skills (research, writing, ability to navigate different modalities)
• time-management skills and the ability to focus on reading and writing
• determined motivation to do a PhD.

How do I choose the topic for my PhD dissertation or thesis?

It’s important to find a topic that will sustain your interest for the years it will take to complete a PhD. “Finding a sustainable topic is the most important thing you [as a PhD student] would do,” says Dr Brabazon in a video for Times Higher Education . “Write down on a big piece of paper all the topics, all the ideas, all the questions that really interest you, and start to cross out all the ones that might just be a passing interest.” Also, she says, impose the “Who cares? Who gives a damn?” question to decide if the topic will be useful in a future academic career.

The availability of funding and scholarships is also often an important factor in this decision, says veteran PhD supervisor Richard Godwin, from Harper Adams University .

Define a gap in knowledge – and one that can be questioned, explored, researched and written about in the time available to you, says Gina Wisker, head of the Centre for Learning and Teaching at the University of Brighton. “Set some boundaries,” she advises. “Don’t try to ask everything related to your topic in every way.”

James Hartley, research professor in psychology at Keele University, says it can also be useful to think about topics that spark general interest. If you do pick something that taps into the zeitgeist, your findings are more likely to be noticed.

You also need to find someone else who is interested in it, too. For STEM candidates , this will probably be a case of joining a team of people working in a similar area where, ideally, scholarship funding is available. A centre for doctoral training (CDT) or doctoral training partnership (DTP) will advertise research projects. For those in the liberal arts and social sciences, it will be a matter of identifying a suitable supervisor .

Avoid topics that are too broad (hunger across a whole country, for example) or too narrow (hunger in a single street) to yield useful solutions of academic significance, write Mark Stephan Felix and Ian Smith. And ensure that you’re not repeating previous research or trying to solve a problem that has already been answered. A PhD thesis must be original.

What is a thesis proposal?

After you have read widely to refine your topic and ensure that it and your research methods are original, and discussed your project with a (potential) supervisor, you’re ready to write a thesis proposal , a document of 1,500 to 3,000 words that sets out the proposed direction of your research. In the UK, a research proposal is usually part of the application process for admission to a research degree. As with the final dissertation itself, format varies among disciplines, institutions and countries but will usually contain title page, aims, literature review, methodology, timetable and bibliography. Examples of research proposals are available online.

How to write an abstract for a dissertation or thesis

The abstract presents your thesis to the wider world – and as such may be its most important element , says the NUI Galway writing guide. It outlines the why, how, what and so what of the thesis . Unlike the introduction, which provides background but not research findings, the abstract summarises all sections of the dissertation in a concise, thorough, focused way and demonstrates how well the writer understands their material. Check word-length limits with your university – and stick to them. About 300 to 500 words is a rough guide ­– but it can be up to 1,000 words.

The abstract is also important for selection and indexing of your thesis, according to the University of Melbourne guide , so be sure to include searchable keywords.

It is the first thing to be read but the last element you should write. However, Pat Thomson , professor of education at the University of Nottingham , advises that it is not something to be tackled at the last minute.

How to write a stellar conclusion

As well as chapter conclusions, a thesis often has an overall conclusion to draw together the key points covered and to reflect on the unique contribution to knowledge. It can comment on future implications of the research and open up new ideas emanating from the work. It is shorter and more general than the discussion chapter , says online editing site Scribbr, and reiterates how the work answers the main question posed at the beginning of the thesis. The conclusion chapter also often discusses the limitations of the research (time, scope, word limit, access) in a constructive manner.

It can be useful to keep a collection of ideas as you go – in the online forum DoctoralWriting SIG , academic developer Claire Aitchison, of the University of South Australia , suggests using a “conclusions bank” for themes and inspirations, and using free-writing to keep this final section fresh. (Just when you feel you’ve run out of steam.) Avoid aggrandising or exaggerating the impact of your work. It should remind the reader what has been done, and why it matters.

How to format a bibliography (or where to find a reliable model)

Most universities use a preferred style of references , writes THE associate editor Ingrid Curl. Make sure you know what this is and follow it. “One of the most common errors in academic writing is to cite papers in the text that do not then appear in the bibliography. All references in your thesis need to be cross-checked with the bibliography before submission. Using a database during your research can save a great deal of time in the writing-up process.”

A bibliography contains not only works cited explicitly but also those that have informed or contributed to the research – and as such illustrates its scope; works are not limited to written publications but include sources such as film or visual art.

Examiners can start marking from the back of the script, writes Dr Brabazon. “Just as cooks are judged by their ingredients and implements, we judge doctoral students by the calibre of their sources,” she advises. She also says that candidates should be prepared to speak in an oral examination of the PhD about any texts included in their bibliography, especially if there is a disconnect between the thesis and the texts listed.

Can I use informal language in my PhD?

Don’t write like a stereotypical academic , say Kevin Haggerty, professor of sociology at the University of Alberta , and Aaron Doyle, associate professor in sociology at Carleton University , in their tongue-in-cheek guide to the PhD journey. “If you cannot write clearly and persuasively, everything about PhD study becomes harder.” Avoid jargon, exotic words, passive voice and long, convoluted sentences – and work on it consistently. “Writing is like playing guitar; it can improve only through consistent, concerted effort.”

Be deliberate and take care with your writing . “Write your first draft, leave it and then come back to it with a critical eye. Look objectively at the writing and read it closely for style and sense,” advises THE ’s Ms Curl. “Look out for common errors such as dangling modifiers, subject-verb disagreement and inconsistency. If you are too involved with the text to be able to take a step back and do this, then ask a friend or colleague to read it with a critical eye. Remember Hemingway’s advice: ‘Prose is architecture, not interior decoration.’ Clarity is key.”

How often should a PhD candidate meet with their supervisor?

Since the PhD supervisor provides a range of support and advice – including on research techniques, planning and submission – regular formal supervisions are essential, as is establishing a line of contact such as email if the candidate needs help or advice outside arranged times. The frequency varies according to university, discipline and individual scholars.

Once a week is ideal, says Dr Brabazon. She also advocates a two-hour initial meeting to establish the foundations of the candidate-supervisor relationship .

The University of Edinburgh guide to writing a thesis suggests that creating a timetable of supervisor meetings right at the beginning of the research process will allow candidates to ensure that their work stays on track throughout. The meetings are also the place to get regular feedback on draft chapters.

“A clear structure and a solid framework are vital for research,” writes Dr Godwin on THE Campus . Use your supervisor to establish this and provide a realistic view of what can be achieved. “It is vital to help students identify the true scientific merit, the practical significance of their work and its value to society.”

How to proofread your dissertation (what to look for)

Proofreading is the final step before printing and submission. Give yourself time to ensure that your work is the best it can be . Don’t leave proofreading to the last minute; ideally, break it up into a few close-reading sessions. Find a quiet place without distractions. A checklist can help ensure that all aspects are covered.

Proofing is often helped by a change of format – so it can be easier to read a printout rather than working off the screen – or by reading sections out of order. Fresh eyes are better at spotting typographical errors and inconsistencies, so leave time between writing and proofreading. Check with your university’s policies before asking another person to proofread your thesis for you.

As well as close details such as spelling and grammar, check that all sections are complete, all required elements are included , and nothing is repeated or redundant. Don’t forget to check headings and subheadings. Does the text flow from one section to another? Is the structure clear? Is the work a coherent whole with a clear line throughout?

Ensure consistency in, for example, UK v US spellings, capitalisation, format, numbers (digits or words, commas, units of measurement), contractions, italics and hyphenation. Spellchecks and online plagiarism checkers are also your friend.

How do you manage your time to complete a PhD dissertation?

Treat your PhD like a full-time job, that is, with an eight-hour working day. Within that, you’ll need to plan your time in a way that gives a sense of progress . Setbacks and periods where it feels as if you are treading water are all but inevitable, so keeping track of small wins is important, writes A Happy PhD blogger Luis P. Prieto.

Be specific with your goals – use the SMART acronym (specific, measurable, attainable, relevant and timely).

And it’s never too soon to start writing – even if early drafts are overwritten and discarded.

“ Write little and write often . Many of us make the mistake of taking to writing as one would take to a sprint, in other words, with relatively short bursts of intense activity. Whilst this can prove productive, generally speaking it is not sustainable…In addition to sustaining your activity, writing little bits on a frequent basis ensures that you progress with your thinking. The comfort of remaining in abstract thought is common; writing forces us to concretise our thinking,” says Christian Gilliam, AHSS researcher developer at the University of Cambridge ’s Centre for Teaching and Learning.

Make time to write. “If you are more alert early in the day, find times that suit you in the morning; if you are a ‘night person’, block out some writing sessions in the evenings,” advises NUI Galway’s Dermot Burns, a lecturer in English and creative arts. Set targets, keep daily notes of experiment details that you will need in your thesis, don’t confuse writing with editing or revising – and always back up your work.

What work-life balance tips should I follow to complete my dissertation?

During your PhD programme, you may have opportunities to take part in professional development activities, such as teaching, attending academic conferences and publishing your work. Your research may include residencies, field trips or archive visits. This will require time-management skills as well as prioritising where you devote your energy and factoring in rest and relaxation. Organise your routine to suit your needs , and plan for steady and regular progress.

How to deal with setbacks while writing a thesis or dissertation

Have a contingency plan for delays or roadblocks such as unexpected results.

Accept that writing is messy, first drafts are imperfect, and writer’s block is inevitable, says Dr Burns. His tips for breaking it include relaxation to free your mind from clutter, writing a plan and drawing a mind map of key points for clarity. He also advises feedback, reflection and revision: “Progressing from a rough version of your thoughts to a superior and workable text takes time, effort, different perspectives and some expertise.”

“Academia can be a relentlessly brutal merry-go-round of rejection, rebuttal and failure,” writes Lorraine Hope , professor of applied cognitive psychology at the University of Portsmouth, on THE Campus. Resilience is important. Ensure that you and your supervisor have a relationship that supports open, frank, judgement-free communication.

Fonts and Point Size

Use 10-12 point size. Fonts must be embedded in the PDF file to ensure all characters display correctly. 

Recommended Fonts

If you are unsure whether your chosen font will display correctly, use one of the following fonts: 

If fonts are not embedded, non-English characters may not appear as intended. Fonts embedded improperly will be published to DASH as-is. It is the student’s responsibility to make sure that fonts are embedded properly prior to submission. 

Instructions for Embedding Fonts

To embed your fonts in recent versions of Word, follow these instructions from Microsoft:

• Click the File tab and then click Options .
• In the left column, select the Save tab.
• Clear the Do not embed common system fonts check box.

For reference, below are some instructions from ProQuest UMI for embedding fonts in older file formats:

To embed your fonts in Microsoft Word 2010:

• In the File pull-down menu click on Options .
• Choose Save on the left sidebar.
• Check the box next to Embed fonts in the file.
• Click the OK button.
• Save the document.

Note that when saving as a PDF, make sure to go to “more options” and save as “PDF/A compliant”

To embed your fonts in Microsoft Word 2007:

• Click the circular Office button in the upper left corner of Microsoft Word.
• A new window will display. In the bottom right corner select Word Options . 
• Choose Save from the left sidebar.

Using Microsoft Word on a Mac:

Microsoft Word 2008 on a Mac OS X computer will automatically embed your fonts while converting your document to a PDF file.

If you are converting to PDF using Acrobat Professional (instructions courtesy of the Graduate Thesis Office at Iowa State University):  

• Open your document in Microsoft Word. 
• Click on the Adobe PDF tab at the top. Select "Change Conversion Settings." 
• Click on Advanced Settings. 
• Click on the Fonts folder on the left side of the new window. In the lower box on the right, delete any fonts that appear in the "Never Embed" box. Then click "OK." 
• If prompted to save these new settings, save them as "Embed all fonts." 
• Now the Change Conversion Settings window should show "embed all fonts" in the Conversion Settings drop-down list and it should be selected. Click "OK" again. 
• Click on the Adobe PDF link at the top again. This time select Convert to Adobe PDF. Depending on the size of your document and the speed of your computer, this process can take 1-15 minutes. 
• After your document is converted, select the "File" tab at the top of the page. Then select "Document Properties." 
• Click on the "Fonts" tab. Carefully check all of your fonts. They should all show "(Embedded Subset)" after the font name. 
•  If you see "(Embedded Subset)" after all fonts, you have succeeded.

The font used in the body of the text must also be used in headers, page numbers, and footnotes. Exceptions are made only for tables and figures created with different software and inserted into the document.

Tables and figures must be placed as close as possible to their first mention in the text. They may be placed on a page with no text above or below, or they may be placed directly into the text. If a table or a figure is alone on a page (with no narrative), it should be centered within the margins on the page. Tables may take up more than one page as long as they obey all rules about margins. Tables and figures referred to in the text may not be placed at the end of the chapter or at the end of the dissertation.

• Given the standards of the discipline, dissertations in the Department of History of Art and Architecture and the Department of Architecture, Landscape Architecture, and Urban Planning often place illustrations at the end of the dissertation.

Figure and table numbering must be continuous throughout the dissertation or by chapter (e.g., 1.1, 1.2, 2.1, 2.2, etc.). Two figures or tables cannot be designated with the same number. If you have repeating images that you need to cite more than once, label them with their number and A, B, etc. 

Headings should be placed at the top of tables. While no specific rules for the format of table headings and figure captions are required, a consistent format must be used throughout the dissertation (contact your department for style manuals appropriate to the field).

Captions should appear at the bottom of any figures. If the figure takes up the entire page, the caption should be placed alone on the preceding page, centered vertically and horizontally within the margins.

Each page receives a separate page number. When a figure or table title is on a preceding page, the second and subsequent pages of the figure or table should say, for example, “Figure 5 (Continued).” In such an instance, the list of figures or tables will list the page number containing the title. The word “figure” should be written in full (not abbreviated), and the “F” should be capitalized (e.g., Figure 5). In instances where the caption continues on a second page, the “(Continued)” notation should appear on the second and any subsequent page. The figure/table and the caption are viewed as one entity and the numbering should show correlation between all pages. Each page must include a header.

Landscape orientation figures and tables must be positioned correctly and bound at the top so that the top of the figure or table will be at the left margin. Figure and table headings/captions are placed with the same orientation as the figure or table when on the same page. When on a separate page, headings/captions are always placed in portrait orientation, regardless of the orientation of the figure or table. Page numbers are always placed as if the figure were vertical on the page.

If a graphic artist does the figures, Harvard Griffin GSAS will accept lettering done by the artist only within the figure. Figures done with software are acceptable if the figures are clear and legible. Legends and titles done by the same process as the figures will be accepted if they too are clear, legible, and run at least 10 or 12 characters per inch. Otherwise, legends and captions should be printed with the same font used in the text.

Original illustrations, photographs, and fine arts prints may be scanned and included, centered between the margins on a page with no text above or below.

Use of Third-Party Content

In addition to the student's own writing, dissertations often contain third-party content or in-copyright content owned by parties other than you, the student who authored the dissertation. The Office for Scholarly Communication recommends consulting the information below about fair use, which allows individuals to use in-copyright content, on a limited basis and for specific purposes, without seeking permission from copyright holders.

Because your dissertation will be made available for online distribution through DASH , Harvard's open-access repository, it is important that any third-party content in it may be made available in this way.

Fair Use and Copyright 

What is fair use?

Fair use is a provision in copyright law that allows the use of a certain amount of copyrighted material without seeking permission. Fair use is format- and media-agnostic. This means fair use may apply to images (including photographs, illustrations, and paintings), quoting at length from literature, videos, and music regardless of the format. 

How do I determine whether my use of an image or other third-party content in my dissertation is fair use?  

There are four factors you will need to consider when making a fair use claim.

1) For what purpose is your work going to be used?

• Nonprofit, educational, scholarly, or research use favors fair use. Commercial, non-educational uses, often do not favor fair use.
• A transformative use (repurposing or recontextualizing the in-copyright material) favors fair use. Examining, analyzing, and explicating the material in a meaningful way, so as to enhance a reader's understanding, strengthens your fair use argument. In other words, can you make the point in the thesis without using, for instance, an in-copyright image? Is that image necessary to your dissertation? If not, perhaps, for copyright reasons, you should not include the image.  

2) What is the nature of the work to be used?

• Published, fact-based content favors fair use and includes scholarly analysis in published academic venues. 
• Creative works, including artistic images, are afforded more protection under copyright, and depending on your use in light of the other factors, may be less likely to favor fair use; however, this does not preclude considerations of fair use for creative content altogether.

3) How much of the work is going to be used?  

• Small, or less significant, amounts favor fair use. A good rule of thumb is to use only as much of the in-copyright content as necessary to serve your purpose. Can you use a thumbnail rather than a full-resolution image? Can you use a black-and-white photo instead of color? Can you quote select passages instead of including several pages of the content? These simple changes bolster your fair use of the material.

4) What potential effect on the market for that work may your use have?

• If there is a market for licensing this exact use or type of educational material, then this weighs against fair use. If however, there would likely be no effect on the potential commercial market, or if it is not possible to obtain permission to use the work, then this favors fair use. 

For further assistance with fair use, consult the Office for Scholarly Communication's guide, Fair Use: Made for the Harvard Community and the Office of the General Counsel's Copyright and Fair Use: A Guide for the Harvard Community .

What are my options if I don’t have a strong fair use claim? 

Consider the following options if you find you cannot reasonably make a fair use claim for the content you wish to incorporate:

• Seek permission from the copyright holder. 
• Use openly licensed content as an alternative to the original third-party content you intended to use. Openly-licensed content grants permission up-front for reuse of in-copyright content, provided your use meets the terms of the open license.
• Use content in the public domain, as this content is not in-copyright and is therefore free of all copyright restrictions. Whereas third-party content is owned by parties other than you, no one owns content in the public domain; everyone, therefore, has the right to use it.

For use of images in your dissertation, please consult this guide to Finding Public Domain & Creative Commons Media , which is a great resource for finding images without copyright restrictions. 

Who can help me with questions about copyright and fair use?

Contact your Copyright First Responder . Please note, Copyright First Responders assist with questions concerning copyright and fair use, but do not assist with the process of obtaining permission from copyright holders.

Pages should be assigned a number except for the Dissertation Acceptance Certificate . Preliminary pages (abstract, table of contents, list of tables, graphs, illustrations, and preface) should use small Roman numerals (i, ii, iii, iv, v, etc.). All pages must contain text or images.  

Count the title page as page i and the copyright page as page ii, but do not print page numbers on either page .

For the body of text, use Arabic numbers (1, 2, 3, 4, 5, etc.) starting with page 1 on the first page of text. Page numbers must be centered throughout the manuscript at the top or bottom. Every numbered page must be consecutively ordered, including tables, graphs, illustrations, and bibliography/index (if included); letter suffixes (such as 10a, 10b, etc.) are not allowed. It is customary not to have a page number on the page containing a chapter heading.

• Check pagination carefully. Account for all pages.

A copy of the Dissertation Acceptance Certificate (DAC) should appear as the first page. This page should not be counted or numbered. The DAC will appear in the online version of the published dissertation. The author name and date on the DAC and title page should be the same. 

The dissertation begins with the title page; the title should be as concise as possible and should provide an accurate description of the dissertation. The author name and date on the DAC and title page should be the same. 

• Do not print a page number on the title page. It is understood to be page  i  for counting purposes only.

A copyright notice should appear on a separate page immediately following the title page and include the copyright symbol ©, the year of first publication of the work, and the name of the author:

© [ year ] [ Author’s Name ] All rights reserved.

Alternatively, students may choose to license their work openly under a  Creative Commons  license. The author remains the copyright holder while at the same time granting up-front permission to others to read, share, and (depending on the license) adapt the work, so long as proper attribution is given. (By default, under copyright law, the author reserves all rights; under a Creative Commons license, the author reserves some rights.)

• Do  not  print a page number on the copyright page. It is understood to be page  ii  for counting purposes only.

An abstract, numbered as page  iii , should immediately follow the copyright page and should state the problem, describe the methods and procedures used, and give the main results or conclusions of the research. The abstract will appear in the online and bound versions of the dissertation and will be published by ProQuest. There is no maximum word count for the abstract. 

• double-spaced
• left-justified
• indented on the first line of each paragraph
• The author’s name, right justified
• The words “Dissertation Advisor:” followed by the advisor’s name, left-justified (a maximum of two advisors is allowed)
• Title of the dissertation, centered, several lines below author and advisor

Dissertations divided into sections must contain a table of contents that lists, at minimum, the major headings in the following order:

• Front Matter
• Body of Text
• Back Matter

Front matter includes (if applicable):

• acknowledgements of help or encouragement from individuals or institutions
• a dedication
• a list of illustrations or tables
• a glossary of terms
• one or more epigraphs.

Back matter includes (if applicable):

• bibliography
• supplemental materials, including figures and tables
• an index (in rare instances).

Supplemental figures and tables must be placed at the end of the dissertation in an appendix, not within or at the end of a chapter. If additional digital information (including audio, video, image, or datasets) will accompany the main body of the dissertation, it should be uploaded as a supplemental file through ProQuest ETD . Supplemental material will be available in DASH and ProQuest and preserved digitally in the Harvard University Archives.

As a matter of copyright, dissertations comprising the student's previously published works must be authorized for distribution from DASH. The guidelines in this section pertain to any previously published material that requires permission from publishers or other rightsholders before it may be distributed from DASH. Please note:

• Authors whose publishing agreements grant the publisher exclusive rights to display, distribute, and create derivative works will need to seek the publisher's permission for nonexclusive use of the underlying works before the dissertation may be distributed from DASH.
• Authors whose publishing agreements indicate the authors have retained the relevant nonexclusive rights to the original materials for display, distribution, and the creation of derivative works may distribute the dissertation as a whole from DASH without need for further permissions.

It is recommended that authors consult their publishing agreements directly to determine whether and to what extent they may have transferred exclusive rights under copyright. The Office for Scholarly Communication (OSC) is available to help the author determine whether she has retained the necessary rights or requires permission. Please note, however, the Office of Scholarly Communication is not able to assist with the permissions process itself.

• Missing Dissertation Acceptance Certificate.  The first page of the PDF dissertation file should be a scanned copy of the Dissertation Acceptance Certificate (DAC). This page should not be counted or numbered as a part of the dissertation pagination.
• Conflicts Between the DAC and the Title Page.  The DAC and the dissertation title page must match exactly, meaning that the author name and the title on the title page must match that on the DAC. If you use your full middle name or just an initial on one document, it must be the same on the other document.  
• Abstract Formatting Errors. The advisor name should be left-justified, and the author's name should be right-justified. Up to two advisor names are allowed. The Abstract should be double spaced and include the page title “Abstract,” as well as the page number “iii.” There is no maximum word count for the abstract. 
•  The front matter should be numbered using Roman numerals (iii, iv, v, …). The title page and the copyright page should be counted but not numbered. The first printed page number should appear on the Abstract page (iii). 
• The body of the dissertation should be numbered using Arabic numbers (1, 2, 3, …). The first page of the body of the text should begin with page 1. Pagination may not continue from the front matter. 
• All page numbers should be centered either at the top or the bottom of the page.
• Figures and tables Figures and tables must be placed within the text, as close to their first mention as possible. Figures and tables that span more than one page must be labeled on each page. Any second and subsequent page of the figure/table must include the “(Continued)” notation. This applies to figure captions as well as images. Each page of a figure/table must be accounted for and appropriately labeled. All figures/tables must have a unique number. They may not repeat within the dissertation.
• Any figures/tables placed in a horizontal orientation must be placed with the top of the figure/ table on the left-hand side. The top of the figure/table should be aligned with the spine of the dissertation when it is bound. 
• Page numbers must be placed in the same location on all pages of the dissertation, centered, at the bottom or top of the page. Page numbers may not appear under the table/ figure.
• Supplemental Figures and Tables. Supplemental figures and tables must be placed at the back of the dissertation in an appendix. They should not be placed at the back of the chapter. 
• Permission Letters Copyright. permission letters must be uploaded as a supplemental file, titled ‘do_not_publish_permission_letters,” within the dissertation submission tool.

It’s a beacon of knowledge, guiding future researchers and shaping the trajectory of scholarly discourse. Understanding its significance is the first step toward unlocking the secrets of its length.

Navigating Length: A Delicate Balancing Act

Determining the appropriate length for a Ph.D. dissertation is no mere formality. It’s a delicate dance between providing comprehensive insights and maintaining reader engagement. Striking this balance is crucial, as the length not only influences how the research is perceived but also reflects the researcher’s ability to weave a compelling narrative without unnecessary verbosity.

Factors in the Equation

The length of a dissertation is a dynamic variable influenced by a multitude of factors. From the complexity of the research question to the intricacies of data collection, each element plays a role. It’s a symphony where the depth of the literature review, the intricacy of the methodology, and the nature of the chosen discipline all contribute to the final crescendo of the dissertation length.

Purpose of a PhD Dissertation

At the heart of the Ph.D. journey lies the dissertation, a formidable endeavour that goes beyond being a mere academic requirement. It serves as the cornerstone of a scholar’s intellectual legacy, encapsulating years of research, critical thinking, and a commitment to advancing knowledge in a specific field. The purpose of a Ph.D. dissertation extends far beyond a graduation requirement; it is a scholarly rite of passage that marks one’s entry into the ranks of contributing intellectuals.

B. The Dissertation’s Role in Academic Knowledge

The dissertation, in essence, is a torchbearer of academic knowledge. It doesn’t merely regurgitate existing information but actively contributes to the ongoing conversation within a field. Picture it as a puzzle piece that, when seamlessly integrated, enriches the larger mosaic of human understanding. Its role is not just to summarize what is known but to illuminate uncharted territories, challenging established paradigms and paving the way for new insights.

Example: In the field of environmental science, a Ph.D. dissertation might delve into the impact of climate change on a specific ecosystem, offering novel findings that reshape our understanding of ecological resilience. It becomes a pivotal contribution that informs future research and policy decisions.

Thorough research is the bedrock upon which a meaningful dissertation stands. It involves meticulously exploring existing literature, methodologies, and gaps in knowledge. This isn’t a cursory glance but a deep dive into the scholarly ocean, where each wave of information contributes to the construction of a comprehensive understanding.

Original contributions are the soul of a Ph.D. dissertation. It’s not just about rehashing what’s already known but about introducing something new and transformative. This could be a novel research methodology, a groundbreaking theory, or empirical findings that challenge existing theories.

Example: In the realm of psychology, a Ph.D. dissertation might involve the development of a new therapeutic approach for a specific mental health condition, backed by both a comprehensive review of existing literature and empirical evidence from original studies. This not only adds to the academic discourse but also has tangible implications for clinical practice.

University Guidelines PhD Dissertation Length: Navigating the Academic Framework

In academia, each university sets the stage with its own set of guidelines governing the composition and expectations of a Ph.D. dissertation. These guidelines serve as the rulebook, providing a roadmap for aspiring scholars to traverse the challenging terrain of research and writing. Understanding these guidelines is akin to deciphering the code that unlocks the door to doctoral success.

Dive into the particulars, and you’ll find that universities often outline specific requirements and expectations regarding the length of a dissertation. These may range from prescribed word counts for each section to broader expectations for the overall document. Some institutions might emphasize brevity, while others encourage a more expansive exploration. Unravelling these expectations is not just a bureaucratic formality; it’s a strategic move that ensures your work aligns with the academic standards set by your institution.

Example: Imagine a university that places a strong emphasis on concise and focused dissertations. Here, the guidelines may state a maximum word count for each chapter, encouraging a streamlined and impactful presentation of research findings. Adhering to these specifics ensures that your dissertation not only meets the academic standards but also resonates with the evaluators who appreciate clarity and precision.

While the allure of academic freedom may tempt scholars to chart their own course, adherence to institutional guidelines is paramount. It’s not just a matter of compliance; it’s a strategic decision that aligns your work with the expectations of the academic community. Universities set guidelines with a purpose – to maintain standards, ensure consistency, and facilitate fair evaluation. Ignoring these guidelines can inadvertently hinder the reception of your dissertation, potentially overshadowing the brilliance of your research with concerns about adherence to academic norms.

Disciplinary Variances: Navigating the Length Spectrum

In the vast landscape of academia, one size certainly does not fit all, especially when it comes to the length of Ph.D. dissertations. It’s crucial to acknowledge and appreciate the dynamic nature of disciplinary differences, where each field has its own set of expectations, traditions, and scholarly norms. Understanding this diversity is the key to crafting a dissertation that resonates within the specific academic community to which it belongs.

Let’s take a stroll through different academic landscapes to grasp the breadth of expectations. In the sciences, precision and brevity often reign supreme. A molecular biology dissertation, for instance, may prioritize concise methodology and results chapters, with an emphasis on data interpretation. Contrast this with a dissertation in the humanities, where the richness of language and the depth of literary analysis might lead to a more extensive exploration of concepts.

Example: In engineering, a Ph.D. dissertation might lean towards a succinct presentation of methodologies, experimental results, and their implications for the field. Meanwhile, in the realm of philosophy, a dissertation could be characterized by a more expansive engagement with existing literature and a thorough philosophical exploration of the research question.

The beauty of academia lies in its diversity, but this very diversity requires scholars to be attuned to the norms of their specific discipline. What might be considered a concise and impactful dissertation in one field could be seen as lacking depth in another. Recognizing these norms is not just a matter of fitting in; it’s a strategic decision that ensures your work aligns with the expectations of your academic peers.

Understanding disciplinary norms is like speaking the language of your scholarly community. It’s about knowing when to be succinct and when to elaborate, when to prioritize methodology and when to delve deep into theoretical frameworks.

Factors Influencing PhD Dissertation Length

1. Impact of Research Question Complexity

The complexity of your research question is like the compass guiding the depth and breadth of your dissertation. Intricate inquiries often demand more comprehensive exploration, delving into multiple facets and dimensions. For instance, a research question investigating the genetic determinants of a rare disease may necessitate an extensive review of existing literature, detailed methodologies, and intricate analyses to uncover meaningful insights.

2. Examples of Research Topics

Consider the following examples to illustrate the point:

• Less Complex: An analysis of consumer behavior in response to a specific marketing strategy might require a detailed but more straightforward exploration.
• More Complex: On the other hand, a study examining the intersection of artificial intelligence and ethical considerations in healthcare may demand a multifaceted investigation into both technological and ethical dimensions, significantly impacting the length of the dissertation.

1. Influence of Data Nature and Quantity

The nature and amount of data collected cast a profound shadow on dissertation length. A project relying on extensive datasets, intricate statistical analyses, or comprehensive case studies inherently demands a more extended exploration. In contrast, qualitative research might be more concise but equally impactful in unraveling complex phenomena.

2. Role of Statistical Analysis, Case Studies, or Qualitative Research

Consider the following scenarios:

• Statistical Analysis: A dissertation delving into the economic impact of climate change policies might involve sophisticated statistical models and require an in-depth presentation of results and their implications.
• Qualitative Research: Conversely, a dissertation employing qualitative interviews to explore the lived experiences of individuals facing a specific social challenge may present findings in a more narrative form.

1. Significance of a Comprehensive Literature Review

A robust literature review acts as the scaffolding for your dissertation, providing the theoretical foundation and context for your research. The broader and more complex the field, the more extensive the literature review. For instance, exploring a niche area within a rapidly evolving field, like emerging technologies, may demand a more thorough literature review to capture the latest developments and debates.

2. Contribution to Overall Length

Consider this:

• A dissertation in environmental science, investigating the impact of urbanization on biodiversity, might necessitate a detailed exploration of existing literature on ecology, urban planning, and biodiversity conservation.

1. Impact of Detailed Research Methodology

The methodology section is the blueprint of your research, and its level of detail significantly influences the length of your dissertation. A dissertation with a meticulous methodology section is like a well-constructed building, providing a clear roadmap for readers to understand the research process.

2. Need for Clarity and Precision in Research Design

For example:

• A dissertation in public health aiming to assess the effectiveness of a health intervention might require a detailed explanation of the study design, participant recruitment strategies, and data collection methods to ensure the study’s validity and reliability.

Balancing Depth and Brevity: Crafting a Dissertation Masterpiece

In the symphony of scholarly writing, achieving harmony between depth and brevity is a skill that distinguishes a stellar dissertation. While delving deep into the nuances of your research is essential, presenting it with conciseness ensures that your audience remains engaged. The challenge lies in striking the right balance, where the richness of content is not sacrificed on the altar of brevity.

• Clear Research Objectives: Begin with well-defined research objectives that serve as the North Star for your dissertation. This clarity guides your writing, preventing unnecessary tangents and ensuring each section contributes directly to your overarching goals. Example: In a dissertation exploring the impact of mindfulness-based interventions on stress reduction, clear objectives would center around understanding the effectiveness of specific mindfulness techniques and their implications for stress management.
• Thematic Structure: Organize your dissertation thematically, ensuring each chapter has a clear purpose and contributes to building a cohesive narrative. This not only aids readability but also enhances the overall impact of your research. Example: In a literature review, grouping studies thematically—such as by intervention type or outcome measures—provides a structured and focused presentation of existing research, avoiding a scattered and disjointed narrative.
• Rigorous Editing: Approach your writing with a discerning eye during the editing process. Trim unnecessary words, sentences, or sections that do not directly contribute to the core message of your dissertation. Be ruthless in maintaining relevance. Example: In the methodology section, focus on explaining key decisions and processes, omitting redundant details that do not influence the study’s validity or replicability.
• Depth of Analysis: Instead of inundating your dissertation with an abundance of superficial analyses, delve deep into a few key points. Thoroughly explore the significance and implications of your findings, providing a nuanced understanding of your research. Example: In a discussion section, rather than covering multiple tangential points, focus on the most critical aspects of your results, analyzing their theoretical and practical implications in detail.
• Precision in Language: Choose words judiciously to convey your ideas with precision. Aim for clarity without unnecessary embellishments, ensuring that each sentence adds value to your argument. Example: In the introduction, use concise language to clearly articulate the research gap, the significance of the study, and the specific research questions without unnecessary elaboration.
• Selectivity in Citations: While a comprehensive literature review is vital, selectively cite studies that directly contribute to your research context. Avoid an exhaustive list that overwhelms readers with unnecessary details. Example: In a literature review on educational interventions for students with learning disabilities, selectively cite studies that showcase diverse approaches and methodologies, providing a nuanced understanding of the existing landscape.

As we navigate the delicate equilibrium between depth and brevity, remember that a well-crafted dissertation is not measured by its length but by the impact of its scholarly contributions. Join us as we explore the art of balancing substance with succinctness, ensuring your dissertation stands as a masterpiece in the annals of academic inquiry.

Tips for Managing PhD Dissertation Length: Navigating the Dissertation Writing Process

• Setting Realistic Milestones: Break down the dissertation-writing process into manageable milestones. Establish realistic timelines for each section, considering the complexity and time required for research, writing, and revisions. Example: Allocate a specific time frame for conducting literature reviews, data analysis, and drafting each chapter. This ensures steady progress and prevents last-minute rushes.
• Regular Progress Checks: Monitor your progress regularly and adjust your schedule as needed. If a particular section is taking longer than anticipated, evaluate the reasons and recalibrate your timeline accordingly. Example: If data analysis is proving more time-consuming than expected, revisit your research plan and, if necessary, adjust your writing schedule for subsequent chapters.
• Balancing Research and Writing: Strive for a balance between conducting research and writing. While research is crucial, allocate dedicated time for translating findings into written content to avoid a backlog of information. Example: If you’re conducting experiments, allocate specific writing sessions to summarize and interpret the results, ensuring a continuous flow of progress.

• Clarity in Expression: Aim for clarity in your writing. Express complex ideas in straightforward language, avoiding unnecessary jargon or convoluted sentences that can inflate the word count without adding substance. Example: Instead of using complex terminology in a theoretical framework, opt for clear and precise language that conveys the theoretical concepts without unnecessary embellishments.
• Economical Word Choices: Choose words judiciously. Opt for strong, impactful words that convey your message succinctly. Trim redundant phrases and eliminate words that don’t contribute directly to your argument. Example: Instead of saying “due to the fact that,” use the more concise “because” to convey the same meaning with fewer words.
• Strategic Use of Figures and Tables: Incorporate visuals strategically to convey information efficiently. Figures and tables can often replace lengthy textual explanations, providing a visual representation of data or concepts. Example: Instead of describing a complex set of results in paragraphs, present key findings in a well-designed table, allowing readers to grasp the information at a glance.
• Early and Regular Feedback: Share drafts of your work with advisors and peers early in the writing process. Their feedback can identify potential issues and guide revisions, preventing the need for extensive rewrites later. Example: Submit a draft of your literature review to your advisor before completing the entire chapter. Early feedback can help refine your approach and ensure you’re on the right track.
• Objective External Perspectives: Advisors and peers offer valuable external perspectives. They can identify areas where your explanation may be unclear or where additional details may be necessary. Example: If your research methodology is intricate, seek feedback from a peer who is not intimately familiar with your topic. Their questions and comments can reveal where additional clarification is needed for a broader audience.
• Critical Review for Redundancy: Advisors and peers can help identify redundant sections or unnecessary details. A fresh set of eyes can pinpoint areas where content can be streamlined without compromising the depth of your argument. Example: If two sections of your dissertation cover similar ground, feedback from others can highlight the need to merge or eliminate redundant content, improving the overall flow.

How Long is a Dissertation for a PhD?

How long is a dissertation? This is one of the most common questions asked by current or aspiring doctoral students.

A dissertation is an extensive research project that contributes fresh knowledge to the author’s field. Many doctoral programs require students to write, defend, and revise a dissertation to earn their degrees.

Editorial Listing ShortCode:

This article explores the average length of a dissertation and various factors that affect the scope of these papers.

How Long Is a Dissertation?

For most graduate students, the dissertation is the longest and most time-consuming paper they write throughout their education. This project aims to address a research question in the student’s field and build on existing bodies of scholarship.

Additionally, the dissertation showcases the student’s mastery of research methodologies. Because a dissertation must accomplish several goals, they tend to be ambitious and lengthy.

Most dissertations are 100 to 250 pages long. But many factors impact the length of a dissertation, including:

• Academic field . Each discipline has different norms regarding dissertation content and length. For instance, literature dissertations often include extended close readings of texts, while science dissertations focus more on data analysis and research design. As a result, humanities dissertations are typically longer.
• Institutional requirements . Most colleges and universities specify a minimum number of pages for the dissertation. You can ask your academic advisor or the graduate studies office about specific dissertation guidelines.
• Topic complexity . Broad or complex research questions may require more data and analysis to answer, resulting in a longer dissertation.
• Individual writing style . Some doctoral students enjoy writing elaborate and detailed sentences, while others prefer to get straight to the point.
• Research methodologies . The approaches and methods used in the research can dramatically affect the length of the dissertation. For example, some dissertations include case studies, which may require lengthy explanations and analyses. Others use quantitative research methods and may include a number of charts and figures.
• Committee feedback . Graduate students typically write their dissertations under the supervision of a faculty committee. These professors may recommend adding or cutting material during revision, impacting the dissertation’s final length.
• Future goals . Some doctoral students plan to revise their dissertation and publish it as an academic monograph after graduation. Writing a longer dissertation gives them more material to adapt for their book.

Reading dissertations from your department and field can give you a better sense of the typical length.

How Long Are Dissertations by Discipline?

The answer to “how long is a doctoral dissertation?” varies by field. In some disciplines, it’s common for graduate students to spend several years writing extensive manuscripts. Other fields produce shorter dissertations of approximately 100 pages.

Here are a few examples of dissertation norms for different disciplines:

These projects typically consist of a theoretical introduction and a creative project, such as a poetry collection or a series of paintings. Creative dissertations may have fewer than 100 written pages, but the artistic elements can still be time-consuming.
• Chemistry : These dissertations typically range from 100 to 150 pages. They typically describe experimental methodologies and draw conclusions from the author’s findings.
• Computer science : Dissertations in this field are generally 50 to 150 pages long and often include quantitative data and algorithms.
• English : PhD students in this field frequently write lengthy literature reviews and provide in-depth analyses of novels and other texts. English dissertations may range from 200 to 350 pages.

Faculty in your discipline can help you understand dissertation expectations.

Average Dissertation Length Per Chapter

Dissertations typically have similar components and structures across disciplines. Here are six common chapters and their average lengths:

• Introduction : The first chapter introduces the primary research topic and explains its relevance to the field. The introduction also provides a brief overview of the investigation method. Most introductions are 10 to 25 pages long.
• Literature review : This chapter situates the project within the broader discipline. The author analyzes existing sources already written on their research topic and identifies biases or gaps that their own project remedies. Humanities dissertations tend to have 20 to 30 page literature reviews, while STEM dissertations devote 10 to 20 pages to this component.
• Methodology : The third chapter typically focuses on the methods and techniques used to gather data. Ideally, this description should contain all the details that another researcher would need to duplicate the experiment and verify the results. The methodology chapter ranges from 15 to 25 pages, depending on the complexity of the research.
• Findings : This section analyzes the collected data and discusses the results of the research project. It often includes charts, diagrams, and other data visualizations illustrating the findings. This chapter could be 20 to 50 pages, depending on the number of images and the amount of text needed to thoroughly examine the results.
• Discussion : This chapter explains the significance of the results. The author may also compare their findings to previously published scholarship. The discussion is typically 15 to 25 pages.
• Conclusion : The author summarizes their findings, acknowledges the limitations of their research, and suggests avenues for future studies. Most conclusions consist of 15 to 20 pages.

Some dissertations deviate from this format. For instance, English dissertations may devote several chapters to critical analyses of different genres or authors.

What Is a Dissertation?

A dissertation is a lengthy written document that a doctoral student produces based on their original research. This project demonstrates the student’s expertise in their area of specialty and contributes to existing knowledge in the field.

Dissertations typically fall into one of two categories. Empirical dissertations require students to collect and analyze data. For instance, a psychology student may interview people about their mental health, while a marketing student could interpret sales data.

Theoretical dissertations focus on analyzing existing scholarship and secondary sources. For example, a literature student might research psychoanalysis and apply this approach to superhero comics.

How Many Pages Is a Dissertation?

The length of a dissertation varies by discipline, institution, and research project. Some dissertations can be as short as 50 pages, while others may total 400 pages. But the average dissertation ranges from 100 pages to 250 pages.

Dissertations in the humanities and social sciences are typically the most extensive. These projects often include detailed analyses, case studies, and literature reviews. By contrast, dissertations in STEM fields like economics and mathematics are often 150 pages or less.

Students in these disciplines frequently use mathematical formulas and data visualizations to prove their findings, resulting in less text.

Why Are Dissertations So Long?

Dissertations are typically the most extended assignments that students complete in graduate school. Several factors contribute to their length, including:

• Depth of research . Doctoral students can spend several years researching their topic and analyzing data. This extensive work often takes hundreds of pages to summarize and explain.
• Literature review . Most fields have extensive bodies of scholarship, so students spend many pages analyzing sources and contextualizing their projects.
• Bibliography . Dissertations often cite dozens or even hundreds of sources, resulting in lengthy bibliographies.

Also, colleges often require dissertations to include additional materials like abstracts and tables of content.

What’s the Difference Between a Dissertation vs. Thesis?

Depending on the type of graduate program you enroll in, you may be required to write a dissertation or thesis. Here are the main differences between a thesis vs. dissertation .

If you want to develop your own concepts or theories, a dissertation can help you accomplish this goal.

What’s the Difference Between a Capstone vs. Dissertation?

There are doctorate programs with no dissertation. Like some online doctoral programs in education without dissertation requirements, they have a capstone project instead. Here’s a comparison of a dissertation vs. capstone .

Your career goals can help determine if a capstone or dissertation is right for you.

How Long Is a Dissertation for a PhD Degree?

People often wonder, “How long is a PhD dissertation?” These projects are typically 100 to 250 pages long, though dissertations on complex topics may total more than 400 pages.

Writing a dissertation allows you to develop advanced expertise on your chosen research topic. Many students also publish portions of their dissertations as peer-reviewed articles and share their findings at conferences. These activities enhance your CV and may make you more competitive for academic jobs.

You can kickstart your doctoral journey today by researching accredited online programs in your field.

Word limits and requirements of your Degree Committee

Candidates should write as concisely as is possible, with clear and adequate exposition. Each Degree Committee has prescribed the limits of length and stylistic requirements as given below. On submission of the thesis you must include a statement of length confirming that it does not exceed the word limit for your Degree Committee.

These limits and requirements are strictly observed by the Postgraduate Committee and the Degree Committees and, unless approval to exceed the prescribed limit has been obtained beforehand (see: Extending the Word Limit below), a thesis that exceeds the limit may not be examined until its length complies with the prescribed limit.

Extending the Word Limit

Thesis word limits are set by Degree Committees. If candidates need to increase their word limits they will need to apply for permission.

Information on how to apply (via self-service account) is available on the ‘ Applying for a change in your student status’  page. If following your viva, you are required to make corrections to your thesis which will mean you need to increase your word-limit, you need to apply for permission in the same way.

Requirements of the Degree Committees

Archaeology and anthropology, architecture and history of art, asian and middle eastern studies, business and management, clinical medicine and clinical veterinary medicine, computer laboratory, earth sciences and geography, scott polar institute, engineering, history and philosophy of science, land economy, mathematics, modern and medieval languages and linguistics, physics and chemistry, politics and international studies, archaeology and social anthropology.

The thesis is not to exceed 80,000 words (approx. 350 pages) for the PhD degree and 60,000 words for the MSc or MLitt degree. These limits include all text, figures, tables and photographs, but exclude the bibliography, cited references and appendices. More detailed specifications should be obtained from the Division concerned. Permission to exceed these limits will be granted only after a special application to the Degree Committee. The application must explain in detail the reasons why an extension is being sought and the nature of the additional material, and must be supported by a reasoned case from the supervisor containing a recommendation that a candidate should be allowed to exceed the word limit by a specified number of words. Such permission will be granted only under exceptional circumstances. If candidates need to apply for permission to exceed the word limit, they should do so in good time before the date on which a candidate proposes to submit the thesis, by application made to the Graduate Committee.

Biological Anthropology:

Students may choose between two alternative thesis formats for their work:

either in the form of a thesis of not more than 80,000 words in length for the PhD degree and 60,000 words for the MSc or MLitt degree. The limits include all text, in-text citations, figures, tables, captions and footnotes but exclude bibliography and appendices; or

in the form of a collection of at least three research articles for the PhD degree and two research articles for the MSc or MLitt degree, formatted as an integrated piece of research, with a table of contents, one or more chapters that outline the scope and provide an in-depth review of the subject of study, a concluding chapter discussing the findings and contribution to the field, and a consolidated bibliography. The articles may be in preparation, submitted for publication or already published, and the combined work should not exceed 80,000 words in length for the PhD degree and 60,000 words for the MSc or MLitt degree. The word limits include all text, in-text citations, figures, tables, captions, and footnotes but exclude bibliography and appendices containing supplementary information associated with the articles. More information on the inclusion of material published, in press or in preparation in a PhD thesis may be found in the Department’s PhD submission guidelines.

Architecture:

The thesis is not to exceed 80,000 words for the PhD and 60,000 words for the MSc or MLitt degree. Footnotes, references and text within tables are to be counted within the word-limit, but captions, appendices and bibliographies are excluded. Appendices should be confined to such items as catalogues, original texts, translations of texts, transcriptions of interview, or tables.

History of Art:

The thesis is not to exceed 80,000 words for the PhD and 60,000 words for the MLitt degree. To include: footnotes, table of contents and list of illustrations, but excluding acknowledgements and the bibliography. Appendices (of no determined word length) may be permitted subject to the approval of the candidate's Supervisor (in consultation with the Degree Committee); for example, where a catalogue of works or the transcription of extensive primary source material is germane to the work. Permission to include such appendices must be requested from the candidate's Supervisor well in advance of the submission of the final thesis. NB: Permission for extensions to the word limit for most other purposes is likely to be refused.

The thesis is for the PhD degree not to exceed 80,000 words exclusive of footnotes, appendices and bibliography but subject to an overall word limit of 100,000 words exclusive of bibliography. For the MLitt degree not to exceed 60,000 words inclusive of footnotes but exclusive of bibliography and appendices.

The thesis for the PhD is not to exceed 60,000 words in length (80,000 by special permission), exclusive of tables, footnotes, bibliography, and appendices. Double-spaced or one-and-a-half spaced. Single or double-sided printing.

The thesis for the MPhil in Biological Science is not to exceed 20,000 words in length, exclusive of tables, footnotes, bibliography, and appendices. Double-spaced or one-and-a-half spaced. Single or double-sided printing.

For the PhD Degree the thesis is not to exceed 80,000 words, EXCLUDING bibliography, but including tables, tables of contents, footnotes and appendices. It is normally expected to exceed 40,000 words unless prior permission is obtained from the Degree Committee. Each page of statistical tables, charts or diagrams shall be regarded as equivalent to a page of text of the same size. The Degree Committee do not consider applications to extend this word limit.

For the Doctor of Business (BusD) the thesis will be approximately 200 pages (a maximum length of 80,000 words, EXCLUDING bibliography, but including tables, tables of contents, footnotes and appendices).

For the MSc Degree the thesis is not to exceed 40,000 words, EXCLUDING bibliography, but including tables, tables of contents, footnotes and appendices.

The thesis is not to exceed 80,000 words including footnotes, references, and appendices but excluding bibliography; a page of statistics shall be regarded as the equivalent of 150 words. Only under exceptional circumstances will permission be granted to exceed this limit. Candidates must submit with the thesis a signed statement giving the length of the thesis.

For the PhD degree, not to exceed 60,000 words (or 80,000 by special permission of the Degree Committee), and for the MSc degree, not to exceed 40,000 words. These limits exclude figures, photographs, tables, appendices and bibliography. Lines to be double or one-and-a-half spaced; pages to be double or single sided.

The thesis is not to exceed, without the prior permission of the Degree Committee, 60,000 words including tables, footnotes and equations, but excluding appendices, bibliography, photographs and diagrams. Any thesis which without prior permission of the Degree Committee exceeds the permitted limit will be referred back to the candidate before being forwarded to the examiners.

The thesis is not to exceed 80,000 words for the PhD degree and the MLitt degree, including footnotes, references and appendices but excluding bibliography. Candidates must submit with the thesis a signed statement giving the length of the thesis. Only under exceptional circumstances will permission be granted to exceed this limit for the inclusion of an appendix of a substantial quantity of text which is necessary for the understanding of the thesis (e.g. texts in translation, transcription of extensive primary source material). Permission must be sought at least three months before submission of the thesis and be supported by a letter from the supervisor certifying that such exemption from the prescribed limit of length is absolutely necessary.

The thesis is not to exceed, without the prior permission of the Degree Committee, 80,000 words for the PhD degree and 60,000 words for the MSc or MLitt degree, including the summary/abstract.  The table of contents, photographs, diagrams, figure captions, appendices, bibliography and acknowledgements to not count towards the word limit. Footnotes are not included in the word limit where they are a necessary part of the referencing system used.

Earth Sciences:

The thesis is not to exceed, without the prior permission of the Degree Committee, 275 numbered pages of which not more than 225 pages are text, appendices, illustrations and bibliography. A page of text is A4 one-and-a-half-spaced normal size type. The additional 50 pages may comprise tables of data and/or computer programmes reduced in size.

If a candidate's work falls within the social sciences, candidates are expected to observe the limit described in the Department of Geography above; if, however, a candidate's work falls within the natural sciences, a candidate should observe the limit described in the Department of Earth Sciences.

Applications for the limit of length of the thesis to be exceeded must be early — certainly no later than the time when the application for the appointment of examiners and the approval of the title of the thesis is made. Any thesis which, without the prior permission of the Degree Committee, exceeds the permitted limit of length will be referred back to the candidate before being forwarded to the examiners.

The thesis is not to exceed, without the prior permission of the Degree Committee, 60,000 words including tables, footnotes, bibliography and appendices. The Degree Committee points out that some of the best thesis extend to only half this length. Each page of statistical tables, charts or diagrams shall be regarded as equivalent to a page of text of the same size.

The thesis is not to exceed 80,000 words for the PhD and EdD degrees and 60,000 words for the MSc and MLitt degrees, in all cases excluding appendices, footnotes, reference list or bibliography. Only in the most exceptional circumstances will permission be given to exceed the stated limits. In such cases, you must make an application to the Degree Committee as early as possible -and no later than three months before it is proposed to submit the thesis, having regard to the dates of the Degree Committee meetings. Your application should (a) explain in detail the reasons why you are seeking the extension and (b) be accompanied by a full supporting statement from your supervisor showing that the extension is absolutely necessary in the interests of the total presentation of the subject.

For the PhD degree, not to exceed, without prior permission of the Degree Committee, 65,000 words, including appendices, footnotes, tables and equations not to contain more than 150 figures, but excluding the bibliography. A candidate must submit with their thesis a statement signed by the candidate themself giving the length of the thesis and the number of figures. Any thesis which, without the prior permission of the Degree Committee, exceeds the permitted limit will be referred back to the candidate before being forwarded to the examiners.

The thesis is not to exceed 80,000 words or go below 60,000 words for the PhD degree and not to exceed 60,000 words or go below 45,000 words for the MLitt degree, both including all notes and appendices but excluding the bibliography. A candidate must add to the preface of the thesis the following signed statement: 'The thesis does not exceed the regulation length, including footnotes, references and appendices but excluding the bibliography.'

In exceptional cases (when, for example, a candidate's thesis largely consists of an edition of a text) the Degree Committee may grant permission to exceed these limits but in such instances (a) a candidate must apply to exceed the length at least three months before the date on which a candidate proposes to submit their thesis and (b) the application must be supported by a letter from a candidate's supervisor certifying that such exemption from the prescribed limit of length is absolutely necessary.

It is a requirement of the Degree Committee for the Faculty of English that thesis must conform to either the MHRA Style Book or the MLA Handbook for the Writers of Research papers, available from major bookshops. There is one proviso, however, to the use of these manuals: the Faculty does not normally recommend that students use the author/date form of citation and recommends that footnotes rather than endnotes be used. Bibliographies and references in thesis presented by candidates in ASNaC should conform with either of the above or to the practice specified in Cambridge Studies in Anglo-Saxon England.

Thesis presented by candidates in the Research Centre for English and Applied Linguistics must follow as closely as possible the printed style of the journal Applied Linguistics and referencing and spelling conventions should be consistent.

A signed declaration of the style-sheet used (and the edition, if relevant) must be made in the preliminary pages of the thesis.

PhD theses MUST NOT exceed 80,000 words, and will normally be near that length.

A minimum word length exists for PhD theses: 70,000 words (50,000 for MLitt theses)

The word limit includes appendices and the contents page but excludes the abstract, acknowledgments, footnotes, references, notes on transliteration, bibliography, abbreviations and glossary.  The Contents Page should be included in the word limit. Statistical tables should be counted as 150 words per table. Maps, illustrations and other pictorial images count as 0 words. Graphs, if they are the only representation of the data being presented, are to be counted as 150 words. However, if graphs are used as an illustration of statistical data that is also presented elsewhere within the thesis (as a table for instance), then the graphs count as 0 words.

Only under exceptional circumstances will permission be granted to exceed this limit. Applications for permission are made via CamSIS self-service pages. Applications must be made at least four months before the thesis is bound. Exceptions are granted when a compelling intellectual case is made.

The thesis is not to exceed 80,000 words for the PhD degree and 60,000 words for the MLitt degree, in all cases including footnotes and appendices but excluding bibliography. Permission to submit a thesis falling outside these limits, or to submit an appendix which does not count towards the word limit, must be obtained in advance from the Degree Committee.

The thesis is not to exceed 80,000 for the PhD degree and 60,000 words for the MSc or MLitt degree, both including footnotes, references and appendices but excluding bibliographies. One A4 page consisting largely of statistics, symbols or figures shall be regarded as the equivalent of 250 words. A candidate must add to the preface of their thesis the following signed statement: 'This thesis does not exceed the regulation length, including footnotes, references and appendices.'

For the PhD degree the thesis is not to exceed 80,000 words (exclusive of footnotes, appendices and bibliography) but subject to an overall word limit of 100,000 words (exclusive of bibliography, table of contents and any other preliminary matter). Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy. For the MLitt degree the thesis is not to exceed 60,000 words inclusive of footnotes but exclusive of bibliography, appendices, table of contents and any other preliminary matter. Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy.

Criminology:

For the PhD degree submission of a thesis between 55,000 and 80,000 words (exclusive of footnotes, appendices and bibliography) but subject to an overall word limit of 100,000 words (exclusive of bibliography, table of contents and any other preliminary matter). Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy. For the MLitt degree the thesis is not to exceed 60,000 words inclusive of footnotes but exclusive of bibliography, appendices, table of contents and any other preliminary matter. Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy.

There is no standard format for the thesis in Mathematics.  Candidates should discuss the format appropriate to their topic with their supervisor.

The thesis is not to exceed 80,000 words for the PhD degree and 60,000 words for the MLitt degree, including footnotes and appendices but excluding the abstract, any acknowledgements, contents page(s), abbreviations, notes on transliteration, figures, tables and bibliography. Brief labels accompanying illustrations, figures and tables are also excluded from the word count. The Degree Committee point out that some very successful doctoral theses have been submitted which extend to no more than three-quarters of the maximum permitted length.

In linguistics, where examples are cited in a language other than Modern English, only the examples themselves will be taken into account for the purposes of the word limit. Any English translations and associated linguistic glosses will be excluded from the word count.

In theses written under the aegis of any of the language sections, all sources in the language(s) of the primary area(s) of research of the thesis will normally be in the original language. An English translation should be provided only where reading the original language is likely to fall outside the expertise of the examiners. Where such an English translation is given it will not be included in the word count. In fields where the normal practice is to quote in English in the main text, candidates should follow that practice. If the original text needs to be supplied, it should be placed in a footnote. These fields include, but are not limited to, general linguistics and film and screen studies.

Since appendices are included in the word limit, in some fields it may be necessary to apply to exceed the limit in order to include primary data or other materials which should be available to the examiners. Only under the most exceptional circumstances will permission be granted to exceed the limit in other cases. In all cases (a) a candidate must apply to exceed the prescribed maximum length at least three months before the date on which a candidate proposes to submit their thesis and (b) the application must be accompanied by a full supporting statement from the candidate's supervisor showing that such exemption from the prescribed limit of length is absolutely necessary.

It is a requirement within all language sections of MMLL, and also for Film, that dissertations must conform with the advice concerning abbreviations, quotations, footnotes, references etc published in the Style Book of the Modern Humanities Research Association (Notes for Authors and Editors). For linguistics, dissertations must conform with one of the widely accepted style formats in their field of research, for example the style format of the Journal of Linguistics (Linguistic Association of Great Britain), or of Language Linguistic Society of America) or the APA format (American Psychology Association). If in doubt, linguistics students should discuss this with their supervisor and the PhD Coordinator.

The thesis is not to exceed 80,000 words for the PhD degree and 60,000 words for the MLitt degree, both excluding notes, appendices, and bibliographies, musical transcriptions and examples, unless a candidate make a special case for greater length to the satisfaction of the Degree Committee. Candidates whose work is practice-based may include as part of the doctoral submission either a portfolio of substantial musical compositions, or one or more recordings of their own musical performance(s).

PhD (MLitt) theses in Philosophy must not be more than 80,000 (60,000) words, including appendices and footnotes but excluding bibliography.

Institute of Astronomy, Department of Materials Science & Metallurgy, Department of Physics:

The thesis is not to exceed, without prior permission of the Degree Committee, 60,000 words, including summary/abstract, tables, footnotes and appendices, but excluding table of contents, photographs, diagrams, figure captions, list of figures/diagrams, list of abbreviations/acronyms, bibliography and acknowledgements.

Department of Chemistry:

Appendices are relevant to the material contained within the thesis but do not form part of the connected argument. Specifically, they may include derivations, code and spectra, as well as experimental information (compound name, structure, method of formation and data) for non-key molecules made during the PhD studies.

Applicable to the PhDs in Politics & International Studies, Latin American Studies, Multi-disciplinary Studies and Development Studies for all submissions from candidates admitted prior to and including October 2017.

A PhD thesis must not exceed 80,000 words, and will normally be near that length. The word limit includes appendices but excludes footnotes, references and bibliography. Footnotes should not exceed 20% of the thesis. Discursive footnotes are generally discouraged, and under no circumstances should footnotes be used to include material that would normally be in the main text, and thus to circumvent the word limits. Statistical tables should be counted as 150 words per table. Only under exceptional circumstances, and after prior application, will the Degree Committee allow a student to exceed these limits. A candidate must submit, with the thesis, a statement signed by her or himself attesting to the length of the thesis. Any thesis that exceeds the limit will be referred back to candidate for revision before being forwarded to the examiners.

Applicable to the PhDs in Politics & International Studies, Latin American Studies, Multi-disciplinary Studies and Development Studies for all submissions from candidates admitted after October 2017.

Statistical tables should be counted as 150 words per table. Only under exceptional circumstances, and after prior application, will the Degree Committee allow a student to exceed these limits. Applications should be made in good time before the date on which a candidate proposes to submit the thesis, made to the Graduate Committee. A candidate must submit, with the thesis, a statement signed by her or himself attesting to the length of the thesis. Any thesis that exceeds the limit will be referred back to candidate for revision before being forwarded to the examiners.

A PhD thesis must not exceed 80,000 words, and will normally be over 60,000 words. This word limit includes footnotes and endnotes, but excludes appendices and reference list / bibliography. Figures, tables, images etc should be counted as the equivalent of 150 words for each page, or part of a page, that they occupy. Other media may form part of the thesis by prior arrangement with the Degree Committee. Students may apply to the Degree Committee for permission to exceed the word limit, but such applications are granted only rarely. Candidates must submit, with the thesis, a signed statement attesting to the length of the thesis.

PhD Thesis Guide

This phd thesis guide will guide you step-by-step through the thesis process, from your initial letter of intent to submission of the final document..

All associated forms are conveniently consolidated in the section at the end.

Deadlines & Requirements

Students should register for HST.ThG during any term in which they are conducting research towards their thesis. Regardless of year in program students registered for HST.ThG in a regular term (fall or spring) must meet with their research advisor and complete the  Semi-Annual PhD Student Progress Review Form to receive credit.

Years 1 - 2

• Students participating in lab rotations during year 1, may use the optional MEMP Rotation Registration Form , to formalize the arrangement and can earn academic credit by enrolling in HST.599. 
• A first letter of intent ( LOI-1 ) proposing a general area of thesis research and research advisor is required by April 30th of the second year of registration.
• A second letter of intent ( LOI-2 ) proposing a thesis committee membership and providing a more detailed description of the thesis research is required by April 30th of the third year of registration for approval by the HST-IMES Committee on Academic Programs (HICAP).

Year 4 

• Beginning in year 4, (or after the LOI-2 is approved) the student must meet with their thesis committee at least once per semester.
• Students must formally defend their proposal before the approved thesis committee, and submit their committee approved proposal to HICAP  by April 30 of the forth year of registration.
• Meetings with the thesis committee must be held at least once per semester. 

HST has developed these policies to help keep students on track as they progress through their PhD program. Experience shows that students make more rapid progress towards graduation when they interact regularly with a faculty committee and complete their thesis proposal by the deadline.

Getting Started

The Thesis Committee: Roles and Responsibilities

Students perform doctoral thesis work under the guidance of a thesis committee consisting of at least three faculty members from Harvard and MIT (including a chair and a research advisor) who will help guide the research. Students are encouraged to form their thesis committee early in the course of the research and in any case by the end of the third year of registration. The HST IMES Committee on Academic Programs (HICAP) approves the composition of the thesis committee via the letter of intent and the thesis proposal (described below). 

Research Advisor

The research advisor is responsible for overseeing the student's thesis project. The research advisor is expected to:

• oversee the research and mentor the student;
• provide a supportive research environment, facilities, and financial support;
• discuss expectations, progress, and milestones with the student and complete the  Semi-Annual PhD Student Progress Review Form each semester;
• assist the student to prepare for the oral qualifying exam;
• guide the student in selecting the other members of the thesis committee;
• help the student prepare for, and attend, meetings of the full thesis committee, to be held at least once per semester;
• help the student prepare for, and attend, the thesis defense;
• evaluate the final thesis document.

The research advisor is chosen by the student and must be a faculty member of MIT* or Harvard University and needs no further approval.  HICAP may approve other individuals as research advisor on a student-by-student basis. Students are advised to request approval of non-faculty research advisors as soon as possible.  In order to avoid conflicts of interest, the research advisor may not also be the student's academic advisor. In the event that an academic advisor becomes the research advisor, a new academic advisor will be assigned.

The student and their research advisor must complete the Semi-Annual PhD Student Progress Review during each regular term in order to receive academic credit for research.  Download Semi Annual Review Form

*MIT Senior Research Staff are considered equivalent to faculty members for the purposes of research advising. No additional approval is required.

Thesis Committee Chair

Each HST PhD thesis committee is headed administratively by a chair, chosen by the student in consultation with the research advisor. The thesis committee chair is expected to:

• provide advice and guidance concerning the thesis research; 
• oversee meetings of the full thesis committee, to be held at least once per semester;
• preside at the thesis defense; 
• review and evaluate the final thesis document.

The thesis committee chair must be well acquainted with the academic policies and procedures of the institution granting the student's degree and be familiar with the student's area of research. The research advisor may not simultaneously serve as thesis committee chair.

For HST PhD students earning degrees through MIT, the thesis committee chair must be an MIT faculty member. A select group of HST program faculty without primary appointments at MIT have been pre-approved by HICAP to chair PhD theses awarded by HST at MIT in cases where the MIT research advisor is an MIT faculty member.**

HST PhD students earning their degree through Harvard follow thesis committee requirements set by the unit granting their degree - either the Biophysics Program or the School of Engineering and Applied Sciences (SEAS).

** List of non-MIT HST faculty approved to chair MIT thesis proposals when the research advisor is an MIT faculty member.

In addition to the research advisor and the thesis committee chair, the thesis committee must include one or more readers. Readers are expected to:

• attend meetings of the full thesis committee, to be held at least once per semester;
• attend the thesis defense; 

Faculty members with relevant expertise from outside of Harvard/MIT may serve as readers, but they may only be counted toward the required three if approved by HICAP.

The members of the thesis committee should have complementary expertise that collectively covers the areas needed to advise a student's thesis research. The committee should also be diverse, so that members are able to offer different perspectives on the student's research. When forming a thesis committee, it is helpful to consider the following questions: 

• Do the individuals on the committee collectively have the appropriate expertise for the project?
• Does the committee include at least one individual who can offer different perspectives on the student's research?  The committee should include at least one person who is not closely affiliated with the student's primary lab. Frequent collaborators are acceptable in this capacity if their work exhibits intellectual independence from the research advisor.
• If the research has a near-term clinical application, does the committee include someone who can add a translational or clinical perspective?  
• Does the committee conform to HST policies in terms of number, academic appointments, and affiliations of the committee members, research advisor, and thesis committee chair as described elsewhere on this page?

[Friendly advice: Although there is no maximum committee size, three or four is considered optimal. Committees of five members are possible, but more than five is unwieldy.]

Thesis Committee Meetings

Students must meet with their thesis committee at least once each semester beginning in the fourth year of registration. It is the student's responsibility to schedule these meetings; students who encounter difficulties in arranging regular committee meetings can contact Julie Greenberg at jgreenbe [at] mit.edu (jgreenbe[at]mit[dot]edu) .

The format of the thesis committee meeting is at the discretion of the thesis committee chair. In some cases, the following sequence may be helpful:

• The thesis committee chair, research advisor, and readers meet briefly without the student in the room;
• The thesis committee chair and readers meet briefly with the student, without the advisor in the room;
• The student presents their research progress, answers questions, and seeks guidance from the members of the thesis committee;

Please note that thesis committee meetings provide an important opportunity for students to present their research and respond to questions. Therefore, it is in the student's best interest for the research advisor to refrain from defending the research in this setting.

Letters of Intent

Students must submit two letters of intent ( LOI-1 and LOI-2 ) with applicable signatures. 

In LOI-1, students identify a research advisor and a general area of thesis research, described in 100 words or less. It should include the area of expertise of the research advisor and indicate whether IRB approval (Institutional Review Board; for research involving human subjects) and/or IACUC approval (Institutional Animal Care and Use Committee; for research involving vertebrate animals) will be required and, if so, from which institutions. LOI-1 is due by April 30 of the second year of registration and and should be submitted to HICAP, c/o Traci Anderson in E25-518. 

In LOI-2, students provide a description of the thesis research, describing the Background and Significance of the research and making a preliminary statement of Specific Aims (up to 400 words total). In LOI-2, a student also proposes the membership of their thesis committee. In addition to the research advisor, the proposed thesis committee must include a chair and one or more readers, all selected to meet the specified criteria . LOI-2 is due by April 30th of the third year of registration and should be submitted to HICAP, c/o Traci Anderson in E25-518.

LOI-2 is reviewed by the HST-IMES Committee on Academic Programs (HICAP) to determine if the proposed committee meets the specified criteria and if the committee members collectively have the complementary expertise needed to advise the student in executing the proposed research. If HICAP requests any changes to the proposed committee, the student must submit a revised LOI-2 for HICAP review by September 30th of the fourth year of registration. HICAP must approve LOI-2 before the student can proceed to presenting and submitting their thesis proposal. Any changes to the thesis committee membership following HICAP approval of LOI-2 and prior to defense of the thesis proposal must be reported by submitting a revised LOI-2 form to HICAP, c/o tanderso [at] mit.edu (Traci Anderson) . After final HICAP approval of LOI-2, which confirms the thesis committee membership, the student may proceed to present their thesis proposal to the approved thesis committee, as described in the next section.

Students are strongly encouraged to identify tentative thesis committee members and begin meeting with them as early as possible to inform the direction of their research. Following submission of LOI-2, students are required to hold at least one thesis committee meeting per semester. Students must document these meetings via the Semi- Annual PhD Student Progress Review form in order to receive a grade reflecting satisfactory progress in HST.ThG.

Thesis Proposal and Proposal Presentation

For MEMP students receiving their degrees through MIT, successful completion of the Oral Qualifying Exam is a prerequisite for the thesis proposal presentation. For MEMP students receiving their degrees through Harvard, the oral qualifying exam satisfies the proposal presentation requirement.

Proposal Document

Each student must present a thesis proposal to a thesis committee that has been approved by HICAP via the LOI-2 and then submit a full proposal package to HICAP by April 30th of the fourth year of registration. The only exception is for students who substantially change their research focus after the fall term of their third year; in those cases the thesis proposal must be submitted within three semesters of joining a new lab. Students registering for thesis research (HST.THG) who have not met this deadline may be administratively assigned a grade of "U" (unsatisfactory) and receive an academic warning.

The written proposal should be no longer than 4500 words, excluding references. This is intended to help students develop their proposal-writing skills by gaining experience composing a practical proposal; the length is comparable to that required for proposals to the NIH R03 Small Research Grant Program. The proposal should clearly define the research problem, describe the proposed research plan, and defend the significance of the work. Preliminary results are not required. If the proposal consists of multiple aims, with the accomplishment of later aims based on the success of earlier ones, then the proposal should describe a contingency plan in case the early results are not as expected.

Proposal Presentation

The student must formally defend the thesis proposal before the full thesis committee that has been approved by HICAP.

Students should schedule the meeting and reserve a conference room and any audio visual equipment they may require for their presentation. To book a conference room in E25, please contact Joseph Stein ( jrstein [at] mit.edu (jrstein[at]mit[dot]edu) ).

Following the proposal presentation, students should make any requested modifications to the proposal for the committee members to review. Once the committee approves the proposal, the student should obtain the signatures of the committee members on the forms described below as part of the proposal submission package.

[Friendly advice: As a professional courtesy, be sure your committee members have a complete version of your thesis proposal at least one week in advance of the proposal presentation.]

Submission of Proposal Package

When the thesis committee has approved the proposal, the student submits the proposal package to HICAP, c/o Traci Anderson in E25-518, for final approval. HICAP may reject a thesis proposal if it has been defended before a committee that was not previously approved via the LOI-2.

The proposal package includes the following: 

• the proposal document
• a brief description of the project background and significance that explains why the work is important;
• the specific aims of the proposal, including a contingency plan if needed; and
• an indication of the methods to be used to accomplish the specific aims.
• signed research advisor agreement form(s);
• signed chair agreement form (which confirms a successful proposal defense);
• signed reader agreement form(s).

Thesis Defense and Final Thesis Document

When the thesis is substantially complete and fully acceptable to the thesis committee, a public thesis defense is scheduled for the student to present his/her work to the thesis committee and other members of the community. The thesis defense is the last formal examination required for receipt of a doctoral degree. To be considered "public", a defense must be announced to the community at least five working days in advance. At the defense, the thesis committee determines if the research presented is sufficient for granting a doctoral degree. Following a satisfactory thesis defense, the student submits the final thesis document, approved by the research advisor, to Traci Anderson via email (see instructions below).

[Friendly advice: Contact jrstein [at] mit.edu (Joseph Stein) at least two weeks before your scheduled date to arrange for advertising via email and posters. A defense can be canceled for insufficient public notice.]

Before the Thesis Defense 

Committee Approves Student to Defend: The thesis committee, working with the student and reviewing thesis drafts, concludes that the doctoral work is complete. The student should discuss the structure of the defense (general guidelines below) with the thesis committee chair and the research advisor. 

Schedule the Defense: The student schedules a defense at a time when all members of the thesis committee will be physical present. Any exceptions must be approved in advance by the IMES/HST Academic Office.

Reserve Room: It is the student's responsibility to reserve a room and any necessary equipment. Please contact imes-reservation [at] mit.edu (subject: E25%20Room%20Reservation) (IMES Reservation) to  reserve rooms E25-140, E25-141, E25-119/121, E25-521. 

Final Draft: A complete draft of the thesis document is due to the thesis committee two weeks prior to the thesis defense to allow time for review.  The thesis should be written as a single cohesive document; it may include content from published papers (see libraries website on " Use of Previously Published Material in a Thesis ") but it may not be a simple compilation of previously published materials.

Publicize the Defense:   The IMES/HST Academic Office invites the community to attend the defense via email and a notice on the HST website. This requires that the student email a thesis abstract and supplemental information to  jrstein [at] mit.edu (Joseph Stein)  two weeks prior to the thesis defense. The following information should be included: Date and time, Location, (Zoom invitation with password, if offering a hybrid option), Thesis Title, Names of committee members, with academic and professional titles and institutional affiliations. The abstract is limited to 250 words for the poster, but students may optionally submit a second, longer abstract for the email announcement.

Thesis Defense Guidelines

Public Defense: The student should prepare a presentation of 45-60 minutes in length, to be followed by a public question and answer period of 15–30 minutes at discretion of the chair.

Committee Discussion:  Immediately following the public thesis presentation, the student meets privately with the thesis committee and any other faculty members present to explore additional questions at the discretion of the faculty. Then the thesis committee meets in executive session and determines whether the thesis defense was satisfactory. The committee may suggest additions or editorial changes to the thesis document at this point.

Chair Confirms Pass: After the defense, the thesis committee chair should inform Traci Anderson of the outcome via email to tanderso [at] mit.edu (tanderso[at]mit[dot]edu) .

Submitting the Final Thesis Document

Know How to Structure Your PhD Thesis

Table of Contents

In your academic career, few projects are more important than your PhD thesis. Unfortunately, many university professors and advisors assume that their students know how to structure a PhD. Books have literally been written on the subject, but there’s no need to read a book in order to know about PhD thesis paper format and structure. With that said, however, it’s important to understand that your PhD thesis format requirement may not be the same as another student’s. The bottom line is that how to structure a PhD thesis often depends on your university and department guidelines.

But, let’s take a look at a general PhD thesis format. We’ll look at the main sections, and how to connect them to each other. We’ll also examine different hints and tips for each of the sections. As you read through this toolkit, compare it to published PhD theses in your area of study to see how a real-life example looks.

Main Sections of a PhD Thesis

In almost every PhD thesis or dissertation, there are standard sections. Of course, some of these may differ, depending on your university or department requirements, as well as your topic of study, but this will give you a good idea of the basic components of a PhD thesis format.

• Abstract : The abstract is a brief summary that quickly outlines your research, touches on each of the main sections of your thesis, and clearly outlines your contribution to the field by way of your PhD thesis. Even though the abstract is very short, similar to what you’ve seen in published research articles, its impact shouldn’t be underestimated. The abstract is there to answer the most important question to the reviewer. “Why is this important?”
• Introduction : In this section, you help the reviewer understand your entire dissertation, including what your paper is about, why it’s important to the field, a brief description of your methodology, and how your research and the thesis are laid out. Think of your introduction as an expansion of your abstract.
• Literature Review : Within the literature review, you are making a case for your new research by telling the story of the work that’s already been done. You’ll cover a bit about the history of the topic at hand, and how your study fits into the present and future.
• Theory Framework : Here, you explain assumptions related to your study. Here you’re explaining to the review what theoretical concepts you might have used in your research, how it relates to existing knowledge and ideas.
• Methods : This section of a PhD thesis is typically the most detailed and descriptive, depending of course on your research design. Here you’ll discuss the specific techniques you used to get the information you were looking for, in addition to how those methods are relevant and appropriate, as well as how you specifically used each method described.
• Results : Here you present your empirical findings. This section is sometimes also called the “empiracles” chapter. This section is usually pretty straightforward and technical, and full of details. Don’t shortcut this chapter.
• Discussion : This can be a tricky chapter, because it’s where you want to show the reviewer that you know what you’re talking about. You need to speak as a PhD versus a student. The discussion chapter is similar to the empirical/results chapter, but you’re building on those results to push the new information that you learned, prior to making your conclusion.
• Conclusion : Here, you take a step back and reflect on what your original goals and intentions for the research were. You’ll outline them in context of your new findings and expertise.

Tips for your PhD Thesis Format

As you put together your PhD thesis, it’s easy to get a little overwhelmed. Here are some tips that might keep you on track.

• Don’t try to write your PhD as a first-draft. Every great masterwork has typically been edited, and edited, and…edited.
• Work with your thesis supervisor to plan the structure and format of your PhD thesis. Be prepared to rewrite each section, as you work out rough drafts. Don’t get discouraged by this process. It’s typical.
• Make your writing interesting. Academic writing has a reputation of being very dry.
• You don’t have to necessarily work on the chapters and sections outlined above in chronological order. Work on each section as things come up, and while your work on that section is relevant to what you’re doing.
• Don’t rush things. Write a first draft, and leave it for a few days, so you can come back to it with a more critical take. Look at it objectively and carefully grammatical errors, clarity, logic and flow.
• Know what style your references need to be in, and utilize tools out there to organize them in the required format.
• It’s easier to accidentally plagiarize than you think. Make sure you’re referencing appropriately, and check your document for inadvertent plagiarism throughout your writing process.

Thesis length.

Research theses have a word limit that you must comply with.

A PhD thesis should not exceed a total of 100,000 words in length (or 70,000 for most professional doctorates), including scholarly apparatus such as footnotes or endnotes, essential appendices and bibliography. A doctoral thesis should however, be concise. Examiners often criticise excessive length, which frequently indicates poor judgement.

When you submit, you will be asked to certify that your thesis falls within the relevant word limit.

In exceptional circumstances, the Dean—Wellington Faculty of Graduate Research may grant permission for you to submit a longer thesis. You will need to apply for permission to exceed the word limit well in advance of submission.

Word limits

• Doctor of Philosophy—100,000 words
• Doctor of Government—70,000 words
• Doctor of Health—70,000 words
• Doctor of Nursing—70,000 words
• Doctor of Midwifery—70,000 words
• Doctor of Education—70,000 words
• Doctor of Musical Arts—40,000 words

Trapped in dissertation revisions?

How long is a dissertation, published by steve tippins on april 9, 2019 april 9, 2019.

Last Updated on: 2nd February 2024, 05:03 am

How long is a dissertation? This is a question that almost every doctoral student asks at some point. It is not a new question–in fact, it’s been asked every time a paper of some sort is assigned in any class.

The simple answer (for any paper) is, “long enough to answer the question.” Not a really helpful answer, but satisfying from a professor’s perspective.

The truth is, there is no one answer to how long a dissertation is. I can’t say 146 pages is what’s needed, as you may write to page 146 and stop without fully exploring your topic. 90 pages could adequately address your research question, or you could write 200 pages and still not fully answer what you set out to. Every topic is unique, as is each person’s writing style.

Some websites even give specific answers that are simply inaccurate. In my experience, dissertations vary too much to be pinned down like that.

However, there are some practical suggestions I can make about how long your dissertation should be, how to adequately address the requirements of each section, as well as how to expand or reduce the length of specific chapters according to your needs. I’ll explore these below.

But first, let’s try and at least give the beginning of an answer to the question “how long is a dissertation?”

Marcus Beck Sets Out to Answer “How Long Is A Dissertation?”

Any discussion of dissertation length must include the work done by Marcus Beck . As a way to distract himself from his own dissertation writing, Beck calculated the average length of dissertations in the University of Minnesota database.

You can see from looking at his data that average length varies by discipline. So the first answer to how long a dissertation is, is that it depends upon what area you are writing your dissertation. It appears that a dissertation in History will be much longer, on average, than one in Chemistry. He also calculated the average across all disciplines.

Don’t be intimidated by how long the average dissertation is.

Many people look at the average length of a dissertation and get intimidated by the high page count. But, as Marcus Beck says in his blog post, “The actual written portion may only account for less than 50% of the page length.”

I’ve found this to be true. References, appendixes, tables and figures, page breaks, and white space all contribute to the high page count. The actual number of words you need to write is likely considerably less than the page count initially implies.

How Long Should My Dissertation Be?

Even though there’s no single answer about how long a dissertation should be, there probably is an ideal range which your dissertation falls into. This depends on your topic of research, but also on other factors. I’ll discuss some of these below.

Institutional Guidelines

I know of schools that have policies such as “Chapter 2 must be at least 40 pages long and no more than 60 pages.” Why this type of requirement? In my mind, there are two reasons.

First, they want to give some sort of guideline for students that is helpful but does not overburden faculty (a 230-page lit review is daunting to read).

Second, credibility is important. An 8-page lit review does not reflect well upon the student or the institution.

Most schools now have a dissertation template with the headings that are needed for most sections. If you take the time to completely fill in the headings with all of the relevant information, you should come up with an adequate number of pages. Remember, in academic writing, we don’t leave much to chance, we tell the reader everything.

Committee Preferences

It is likely that you will get a committee member who will give you priceless advice such as, “more is needed here.” When you get this type of comment it can be frustrating as specific feedback can be much more helpful.

Usually, what a committee member means by comments like this is that you haven’t really convinced the reader that you have fully explored the area or demonstrated a strong understanding of the material. So, expand what you are saying. Don’t imply anything, state it directly. This lets your committee know that you really do get it.

Sometimes you will get committee members giving contradictory advice. One member may want more information and another may want less. My first piece of advice is to negotiate these types of requests through your Chairperson.

This is where your Chair’s experience and guidance can be very helpful. Second, if a member really wants material included but others do not think it is very helpful, then adding the material in an appendix may make everyone happy.

Practical Suggestions For Dissertation Length, Chapter-By-Chapter

If you adequately and succinctly address each required section, you should end up with the right length for each chapter (and therefore, a dissertation of the right length). I’ll also give some rough guidelines on average page length where appropriate.

This is the introduction to your study. It is important to lay out the agenda for your research. Be sure that your problem statement, title, and research questions are in alignment (all referring to the same idea).

Chapter 1 tends to average in the 15-25 page range. If you get beyond 25 pages, you are usually including material that is better presented elsewhere in the dissertation.

Chapter 2 should thoroughly explore the existing research on your topic. However, it shouldn’t go on and on.

• If you are looking to beef up Chapter 2, it is always helpful to add research that supports the methodology that you are planning to use.
• If the chapter is too long, try to reduce the references you cite to those that are the most relevant and recent.

Make sure that you tell the reader what you did and how you did it. What type of analysis did you use and why? How many respondents were involved and how did you find them? The idea is to make sure that readers understand what you did and could replicate it if they want to.

As this is a plan for your research, it seems to naturally fall in the 15 to 20 page range.

The results of your study are presented here. Include all material that will help the reader understand what you found. There is a tendency to inundate the reader with tables, charts, and graphs. If they don’t directly relate to what you found or are redundant they can be included in an appendix. You don’t want to lose your reader in an avalanche of tables and numbers.

In most dissertations, it is Chapter 5 where you get to explain what the results of your research mean and the implications. This is the only chapter where you have some freedom to really express your opinions. Go ahead and do so.

I am always surprised when someone has spent 15 months of their life working on a research topic and they submit a Chapter 5 that is 8 pages long. Spread your wings and really explore what your results mean.

How Long is a Dissertation? Summary

The is no doubt about it, a dissertation is a long document. It is, however, not written in one sitting. You work on it for many months, crafting paragraphs and coming to conclusions. Many people find that because the document can be written in pieces that when it’s all put together, it is longer than expected. Keep writing and adding your thoughts and you will make it.

Many students find it helps to have a supportive guide who’s both been through the dissertation writing process before and is experienced in helping students. If that would be useful to you, feel free to reach out to me about my dissertation coaching or dissertation editing services.

How long does a PhD take?

Study tips Published 1 Jul, 2021  ·  3-minute read

You already know a Doctor of Philosophy is a significant time investment, but just how long does it take to get a PhD?

Here, we look at the possibilities and average timeframes to help you prepare for the exciting journey ahead. We’ve checked in with our Higher Degree by Research team to get the official answers to how long a PhD takes to complete.

How long does a PhD take in Australia?

You should plan for your PhD to take at least 3 years and 3 months to complete when studying full time if you follow an ideal schedule. However, on average, we find people take 3 years and 9 months to complete a full-time PhD at UQ – and 4 years isn’t uncommon, either.

Remember : The world doesn’t pause while you’re doing your PhD. Life happens, which is why many people interrupt or postpone their PhD for a period before returning to the program later. No two candidates have the same journey – and that’s okay.

Keep in mind that these averages are only indicative of how long a PhD takes in Australia. While the timeframe may be similar in some countries, including most of Europe, you may find yourself studying for longer if you take on your PhD elsewhere. For example, 5-7 years (depending on discipline) is common for candidates completing their PhD in the US.

Can you complete a PhD in 2 years?

Occasionally, a candidate and their supervisory team might request special permission to complete a PhD earlier, and these are reviewed on a case-by-case basis. But the volume of work required to create substantial new knowledge in your field means it’s quite impractical to complete your PhD in only 2 years. After all, you’re striving to become the true expert of your chosen topic – this takes time and dedication without any shortcuts.

If you’re looking to undertake a similar program in just 2 years, consider the Master of Philosophy instead. It’s possible to articulate from an MPhil to a PhD – and sometimes completing an MPhil is the ideal way to extend your research skills before committing to a PhD.

How long is a PhD thesis?

Time isn’t the only logistical consideration you need to make when starting a higher degree by research. You may also be wondering how long your PhD dissertation will need to be (in Australia, this is more commonly called your thesis ).

A standard PhD thesis at UQ is up to 80,000 words .

The extensive research and writing required to complete a PhD further demonstrates why 3 years is the minimum timeframe for a PhD.

How can you stay motivated during your PhD program?

We know 3-4 years is a long time to dedicate to a single topic, and up to 80,000 words of academic writing isn’t a small undertaking. While the rewards of completing your PhD are well worth the time and effort , knowing this may not always be enough to keep you feeling inspired.

So, we asked some of our PhD alumni and candidates for their tips on staying motivated and avoiding burnout. Here’s what they had to say:

“I maintained motivation by setting micro goals . I broke up my days into 500-word challenges – I committed to writing a minimum of 500 words every day, no matter what. I also made sure to have regular breaks scheduled every year. This makes sure that I am well rested and have all my planned work completed before I go.”

– Angie Knaggs, who completed a PhD about popular culture representations of masculinity in crisis

“Try to write something every day. It doesn’t matter if it’s good or bad, a big chunk or just something small, on topic or irrelevant. Just get into the habit of writing every day . Also, do some exercise, stay in contact with friends and family, and maintain a life outside of your PhD – don’t let it be all-consuming.”

– Ren Perkins, who is completing a PhD about keeping Indigenous teachers in the profession

“I remember working a lot of nights and weekends on my thesis! But, overall, I found the experience a fulfilling one. I had a great primary supervisor who was very good at keeping their students motivated.”

– Brigid Lynch, who completed a PhD in population health

Preparing a thesis

Guidance on writing your thesis and the support available.

English language requirements

Theses should normally be written in English. In exceptional circumstances, a student may request permission from their Faculty to present a thesis that is written in another language where there is a clear academic justification for doing so, eg. where the language is directly linked to the research project, or where there is a clear benefit to the impact and dissemination of the research.

Likewise, the oral examination should normally be conducted in English, except in cases where there are pedagogic reasons for it to be held in another language, or where there is a formal agreement in place that requires the viva to be conducted in another language. Permission should be sought from the appropriate faculty for a viva to be conducted in a language other than English.

Guidance on writing the thesis

The main source of advice and guidance for students beginning to write their thesis is the supervisory team. Students should discuss the proposed structure of the thesis with their supervisor at an early stage in their research programme, together with the schedule for its production, and the role of the supervisor in checking drafts. Supervisors should be prepared to advise on such matters as undertaking a literature review, referencing and formatting the thesis, and on what should or should not be included in the thesis, including any supplementary or non-standard material.

Additional support is also available via the English Language Teaching Centre (ELTC), which offers academic writing and thesis writing courses. In addition, the University offers a Thesis Mentoring programme  to help students to manage better the process of writing their thesis.

Students may also find it helpful to consult theses from the same subject discipline that are available in institutional repositories such as White Rose Etheses Online or via the British Library’s EThOS service.

Students who intend to include in their thesis any material owned by another person should consider the copyright implications at an early stage and should not leave this until the final stages of completing the thesis. The correct use of third-party copyright material and the avoidance of unfair means are taken very seriously by the University. Attendance at a copyright training session offered by the Library is strongly recommended.

Students should take care to ensure that the identification of any third-party individuals within their thesis (e.g. participants in the research), is only done with the informed consent of those individuals, and in recognition of any potential risks that this may present to them. This is especially important because an electronic copy of the thesis will normally be made publicly available via the White Rose Etheses Online repository.

Use of copyright material

Guidance on good practices in authorship is set out in the GRIP policy expectations.

Good practices in authorship

Acceptable support in writing the thesis

It is acceptable for a student to receive the following support in writing the thesis from the supervisory team (that is additional to the advice and/or information outlined above), if the supervisory team has considered that this support is necessary:

• Where the meaning of the text is not clear the student should be asked to re-write the text in question in order to clarify the meaning.
• If the meaning of the text is unclear, the supervisory team can provide support in correcting grammar and sentence construction to clarify its meaning. If a student requires significant support with written English above what is considered to be correcting grammar and sentence construction, the supervisory team will, at the earliest opportunity, request that the student obtains remedial tuition support from the University’s English Language Teaching Centre.
• The supervisory team cannot rewrite text that changes the meaning of the text (ghost writing/ghost authorship in a thesis is unacceptable).
• The supervisory team can provide guidance on the structure, content and expression of writing.
• The supervisory team can proofread the text.
• Anyone else who may be employed or engaged to proofread the text is only permitted to change spelling and grammar and must not be able to change the content of the thesis.

The Confirmation Review and the oral examination are the key progression milestones for testing whether a thesis is a student's own work.

Requests for an extension to a student’s time limit for the student to improve their standard of written English in the thesis will not be approved. Students who require additional language support should be signposted to appropriate sources of help at an early stage in their degree to avoid such an occurrence.

Yellow Sticker scheme for disabled students

The University runs a sticker scheme for students who have an impairment that can affect aspects of their written communication. This applies to all students, including PGRs submitting a thesis for examination.

Yellow Sticker scheme

The University does not have any regulatory requirements governing the length of theses, but most faculties have established guidelines:

• Arts and Humanities: 40,000 words (MPhil); 75,000 words (PhD)
• Health: 40,000 words (MPhil); 75,000 words (PhD, MD)
• Science: 40,000 words (MPhil); 80,000 words (PhD)
• Social Sciences: 40,000 words (MPhil); 75,000-100,000 words (PhD)

The above word counts exclude footnotes, bibliography and appendices. Where there are no guidelines, students should consult the supervisor as to the length of thesis appropriate to the particular topic of research.

How long does it take to write a PhD thesis?

My short answer is 68 days, but please read the detail below…

Bold resolutions: “Piled Higher and Deeper” by Jorge Cham www.phdcomics.com

As a PhD supervisor I have often been asked ‘How long do you think it will take me to write up my thesis?’ My answer always begins ‘It depends…’ We then continue the conversation with an audit of material already drafted that may contribute (in edited format) to the final thesis. These include the initial literature review from the first year transfer report, and posters, conference papers and journal articles presented and/or published from the on-going work.

For example third year PhD student John Mowbray , who is currently based within the Centre for Social Informatics (CSI) at Edinburgh Napier University , has a strong basis for his literature review chapter in the form of a conference paper delivered at CoLIS 2016 , which is due to be published in full in Information Research later this year. Similarly John’s fellow student Frances Ryan has already published an account of research design for her study. This paper will underpin the writing of her methods chapter.

Then we consider less formal sources, such as any discussions or debates that the student has documented publicly elsewhere, for example in blog posts. See, for instance Lyndsey Jenkins ‘ recent thoughts about the importance of research domain at http://lyndseyjenkins.org. These may well contribute to a section of Lyndsey’s methods chapter when she comes to write up her work in 2018.

The students also have ‘non-public’ material about their work that will be adapted for their theses. These include interim reports for their supervisors and/or other stakeholders. For example, last semester CSI PhD student Iris Buunk wrote a report on some of the empirical work that she has conducted for the body that gave her access to survey respondents. Handwritten ideas and remarks kept in notebooks over the course of PhD registration are also very valuable ‘private’ resources.

Once we have completed this audit, the challenge of transforming all the work completed to date into an 80,000 word thesis appears not to be so great – but of course, it still all needs to be done!

Records from writing up my own PhD have also recently served as another source for answering questions about preparing the main output of the doctoral study. I undertook my PhD part-time over a period of just over four years while working full-time. Throughout this period there were weeks when I could not progress my work at all. This was largely due to other commitments in intensive periods related to teaching such as the marking season towards the end of each semester. There were other times when it was much easier to devote myself to my PhD. For example, I took annual leave in University vacation time for this purpose (rather than went away on holiday). To guard against losing track of my PhD at times when I was too busy to devote any time to it I kept detailed notes of my progress. As a result of this, I know exactly how much time I spent writing up each chapter for the final version of the thesis. Although all PhD theses are different, the proportion of time on each type of chapter may be helpful to those who have resolved to submit their theses in 2017.

In total it took me 68 days to write up my thesis (NB 68 to write up the work, not 68 days to complete the PhD!) This is the equivalent of approximately 14 working weeks, assuming a five day week. It needs to be borne in mind, however, that I was a part-time student. In practice the writing up was done over the last seven months of the four and half years in which I worked on the entire doctoral study.

The largest portion of the writing-up time – around three quarters – was spent on the two chapters that related the findings of my research, and about a fifth on the discussion chapter. My literature review took very little time to write up (just 5 days) because I had already presented much of it in published form. The methods and conclusions chapters did not take very long either (3.5 and 2.5 days respectively) largely because their content was straightforward. My introductory chapter was very short at a page and a half and was thus drafted in just a couple of hours.

As might be deduced from the time allocations given above, I found the results and discussion chapters most heavy-going. The former was due to the quantity of empirical data to convert into a fluent account of the findings, and the latter because of the intellectual challenge of expressing the meaning of the findings and how the outcomes of my study represented an original contribution to the domain. However, once these two elements were ‘cracked’ it was a relatively easy task to pull all the other chapters together.

If you are reading this blog post as a PhD student in the later stages of your work, I would advise you to be prepared for the long haul of writing up your results and the discussion chapters, and ensure that you allocate a high proportion of your write-up time to these accordingly. It is also worth noting that I found that the closer I came to the target of completing my write-up, the more important it was for me to avoid other distractions. You cannot control for all of them (for example, illness), but I would caution against getting actively involved in anything that will take you away from your PhD at this intensive stage, such as planning a big event (for example, a major holiday, a house move, or a family wedding) or starting a new job.

If you are still in the early stages of your doctoral study, my first piece of advice is to plan your conference participation and journal paper publishing activity with the final thesis in mind. Be selective and strategic so that you prioritise engagement in external events that are valuable to the completion of your thesis and/or your future career. Each piece of work that you present externally should progress your study by encouraging you to write-up as you go along (for example in the form of a poster, a set of slides, a full paper), defend your ideas in person within your academic community, seek feedback on work completed to date, and solicit advice on the later stages. You should also be documenting any thoughts or ideas that may be valuable to writing up in a format that make sense to you, whether this be in a set of handwritten notes or in a more public format such as a series of structured blog posts.

Good luck to all those who will submit their theses in 2017!

How Long is a Thesis or Dissertation: College, Grad or PhD

How long is a thesis

As a graduate student, you may have heard that you must complete a certain comprehensive project, either a thesis or a dissertation. In this guide, we will explore how long a thesis should be, the best length for a dissertation, and the optimal length for each part of the two.

If you read on to the end, we will also explore their differences to understand how it informs each length.

Both terms have distinct meanings, although they are sometimes used interchangeably and frequently confused.

Structure-wise, both papers have an introduction, a literature review, a body, a conclusion, a bibliography, and an appendix. That aside, both papers have some differences, as we shall see later on in this article.

How Long Should a Thesis be

Before discussing how long a thesis is, it’s critical to understand what it is. A thesis is a paper that marks the end of a study program.

Mostly, there is the undergraduate thesis, a project that marks the end of a bachelor’s degree, and a master’s thesis that marks the end of a master’s program.

A thesis should be around 50 pages long for a bachelor’s degree and 60-100 pages for a Master’s degree. However, the optimal length of a thesis project depends on the faculty’s instructions and the supervising professor’s expectations . The length also depends on the topic’s technicalities and the extent of research done.

A master’s thesis project is longer because it is a compilation of all your knowledge obtained in your master’s degree.

It basically allows you to demonstrate your abilities in your chosen field.

Often, graduate schools require students pursuing research-oriented degrees to write a thesis.

This is to demonstrate their practical skills before completing their degrees.

In contrast to undergraduate thesis, which are shorter in length and coverage area, usually less than 60 pages. A master’s theses are lengthy scholarly work allowing you to research a topic deeply.

Then you are required to write, expand the topic, and demonstrate what you have learned throughout the program. This is part of why you must write a thesis for some undergrad in some of the courses.

A Master’s thesis necessitates a large amount of research, which may include conducting interviews, surveys, and gathering information ( both primary and secondary) depending on the subject and field of study.

For this reason, the master’s thesis has between 60 and 100 pages, without including the bibliography. Mostly, the topic and research approach determine the length of the paper.

This means that there is no definite number of pages required. However, your thesis should be long enough to clearly and concisely present all important information.

Need Help with your Homework or Essays?

How long should a dissertation be.

A dissertation is a complex, in-depth research paper usually written by Ph.D. students. When writing the dissertation, Ph.D. Students are required to create their research, formulate a hypothesis, and conduct the study.

On average, a dissertation should be at least 90 pages at the minimum and 200 pages at the maximum , depending on the guidelines of the faculty and the professor. The optimal length for a dissertation also depends on the depth of the research done, the components of the file, and the level of study.

Most Ph.D. dissertations papers are between 120 to 200 pages on average.

However, as we said earlier, it all depends on factors like the field of study, and methods of data collection, among others.

Unlike a master’s thesis, which is about 100 pages, a dissertation is at least twice this length.

This is because you must develop a completely new concept, study it, research it, and defend it.

In your Ph.D. program, a dissertation allows you the opportunity to bring new knowledge, theories, or practices to your field of study.

The Lengths of Each Part of a Thesis and Dissertation

Factors determining the length of thesis or dissertation.

As we have seen, there is no definite length of a thesis and dissertation. Most of these two important academic documents average 100 to 400 pages. However, several factors determine their length.

Universities- we all know universities are independent bodies. Also, it’s important to know that each university is different from the other. As a result, the thesis and dissertation length varies depending on the set rules in a certain college or school.

Field of study- some fields of study have rich information, while others have limited information.

For example, you may have much to write about or discover when it comes to science compared to history.

As such, if you are to write a thesis or a dissertation in both fields, one will definitely be longer than the other. Check the time it takes to write a thesis or a dissertation to get more points.

Other factors that affect the length of a thesis or a dissertation include your writing style and the instructor’s specifications. These factors also come into play when it comes to the time taken to defend a thesis or your dissertation.

Tips for the Optimal Length for a Thesis or Dissertation

Instead of writing for length, write for brevity. The goal is to write the smallest feasible document with all of the material needed to describe the study and back up the interpretation. Ensure to avoid irrelevant tangents and excessive repetitions at all costs.

The only repetition required is the main theme. The working hypothesis seeks to be elaborated and proved in your paper.

The theme is developed in the introduction, expanded in the body, and mentioned in the abstract and conclusion.

Here are some tips for writing the right length of thesis and dissertation:

• Remove any interpretation portion which is only tangentially linked to your new findings. 
• Use tables to keep track of information that is repeated.
• Include enough background information for the reader to understand the point of view.
• Make good use of figure captions.
• Let the table stand on its own. I.e., do not describe the contents of the figures and/or tables one by one in the text. Instead, highlight the most important patterns, objects, or trends in the figures and tables in the text.
• Leave out any observations or results in the text that you haven’t provided data.
• Do not include conclusions that aren’t backed up by your findings.
• Remove all inconclusive interpretation and discussion portions. 
• Avoid unnecessary adjectives, prepositional phrases, and adverbs.
• Make your sentences shorter – avoid nesting clauses or phrases.
• Avoid idioms and instead use words whose meaning can be looked up in a dictionary.

Difference between a Thesis and a Dissertation

The most basic distinction between a thesis and a dissertation is when they are written.

While a thesis is a project completed after a master’s program, a dissertation is completed at the end of doctorate studies.

In a thesis, you present the results of your research to demonstrate that you have a thorough understanding of what you have studied during your master’s program.

On the other hand,  a dissertation is your chance to add new knowledge, theories, or practices to your field while pursuing a doctorate. The goal here is to come up with a completely new concept, develop it, and defend it.

A master’s thesis is similar to the types of research papers you’re used to writing in your bachelor’s studies. It involves conducting research on a topic, analyzing it, and then commenting on your findings and how it applies to your research topic.

The thesis aims to demonstrate your capacity to think critically about and explain a topic in depth.

Furthermore, with a thesis, you typically use this time to elaborate on a topic that is most relevant to your professional area of specialization that you intend to pursue.

In a dissertation, on the other hand, you use other people’s research as an inspiration to help you come up with and prove your own hypothesis, idea, or concept. The majority of the data in a dissertation is credited to you.

Last but not least, these two major works differ greatly in length. The average length of a master’s thesis is at least 100 pages.

On the other hand, a doctoral dissertation should be substantially longer because it includes a lot of history and research information, as well as every element of your research, while explaining how you arrived at the information.

It is a complex piece of scholarly work, and it is likely to be twice or thrice the length of a thesis. To know the difference, check the best length for a thesis paper and see more about it.

Here is a Recap of the Differences

• While the thesis is completed at the end of your master’s degree program, a dissertation is written at the end of your doctoral degree program.
• Both documents also vary in length. A thesis should have at least 100 pages, while a doctoral dissertation is longer (over 200 pages)
• In the thesis, you conduct original research; in the dissertation, you use existing research to help you develop your discovery.
• For a thesis, you have to add analysis to the existing work, while a dissertation is part of the analysis of the existing work.
• In comparison to a thesis, a dissertation requires a more thorough study to expand your research in a certain topic.
• The statements in a thesis and a dissertation are distinct. While a thesis statement explains to readers how you will prove an argument in your research, a dissertation hypothesis defines and clarifies the outcomes you expect from your study. Here, you apply a theory to explore a certain topic.
• A dissertation allows you to contribute new knowledge to your field of study, while a thesis makes sure you understand what you have studied in your program and how it applies.

A thesis or a dissertation is a difficult document to compile. However, you should not be worried since your school assigns you a dissertation advisor who is a faculty member.

These advisors or supervisors help you find resources and ensure that your proposal is on the right track when you get stuck.

Check out my guide on the differences between a research paper, proposal, and thesis to understand more about these issues.
