APA recommends using the same font throughout your paper. IRSC Librarians recommend using 12-point Times New Roman font. If not using Times New Roman, then another serif  or  sans serif typeface should be used for its readability. Only use different typeface in figure descriptions, in that case, use a font between 8 and 14 points.

Line Spacing & Margins

Use double-spacing throughout the entire paper.To add double-spacing in Microsoft Word, highlight all the text you want double-spaced, then click on Page Layout . Next to the word Paragraph click on the arrow. Under Spacing , Line Spacing , select Double and then click OK .

Leave 1 in. margins from top to bottom and side to side. Microsoft Word usually is set to 1 in. margins. You can check this by clicking on Page Layout , then click on Margins. The margin you are using is highlighted, select Normal if it is not already selected. 

Number of Spaces after a Period

APA style recommends placing one space  after a period

• that ends a sentence, 
• when the period separates parts of a reference entry, 
• and after author name abbreviations (i.e. Lander, F. K.).

Do not put a space after a period

• for internal abbreviations (i.e., U.S., p.m.).

• APA Research Paper Template with an Abstract

The newest edition of APA, 7th edition does not require the use of an abstract for student papers; however, your instructor may wish you to include one. This template has the abstract included.

Sample Paper

The new APA 7th edition has a format for writing a professional paper as well as one for a student paper. These directions are a set-up for student papers. In the header, on the right, is the page number, starting with 1. Centered on the page is the full title of the paper in boldface type. Place one extra space after the title of the paper. Following is the author (or authors if this is a group paper), the department and institution to which the paper is affiliated, the course number and course name, the professor's name, and the due date of the paper.

The text of your paper begins on the second page. The full title starts it off at the top center of a new page, in boldface font. For the rest of the paper, you only need page numbers in the header. Remember to cite!

Your References start on its own page and goes at the end of your paper. Title it References, centered, and bold-faced at the top. The references are alphabetized and have a hanging indent.

General Guidelines

• Make 1 inch margins on the top, bottom, and sides.
• The first word in every paragraph should be indented one half inch.
• sans serif: 11-point Calibri or 11-point Arial
• serif: 12-point Times New Roman, 11-point Georgia
• Double space the entire research paper, including the title page.
• Left align the text.

APA Paper Components

Every paper should include at least four main sections:

Reference List

Student papers do not typically include a running head, an author note, or an abstract, unless specifically requested by the instructor.

A title page is always required in all APA formatted papers. Students should follow the student title page guidelines, unless their instructor requires them to use the professional version. 

The student title page should include:

• paper title;
• author(s) name(s);
• author affiliation (i.e. the department and the name of the university);
• course number and full name;
• instructor name;
• assignment due date;
• page number (start numbering the title page from 1).
• APA Blog - Title Page Setup
• Student Title Page Guide APA provides a student title page guide to assist students in creating their title pages.

If requested by the instructor, students may need to include an abstract, especially for capstone projects.

The abstract should be one paragraph of between 150 and 250 words. It is not indented. The section label "Abstract" is centered at the top of the page and it is in bold title case.

Text (Main Body)

The text of the paper should start on a new page after the title page (and abstract, if included). On the first page of the text, you should repeat the paper title in title case, bold, and centered.

Use double-spacing throughout the paper, left align the text and indent the first line of each paragraph by one tab key (usually set to 0.5 in.). 

Throughout the body, in-text citations are used and they include the author’s/authors’ name(s) and the publication year, followed by the page number of the text cited if applicable (see the In-Text Citations section).

Organizing a Paper with Headings

In order to effectively organized the ideas in your paper, you can use headings to separate each different section. APA recommends the use of a maximum of five possible headings. Not all papers must include headings.

• APA Blog - Headings

The Reference List appears on a new page after the end of the paper.

• Center and bold the title “References” (do not include quotation marks, underline, or italicize this title).
• Alphabetize and double-space all entries.
• Use a hanging indent for all entries (the first line of each reference is flush left and subsequent lines are indented by 0.5 in).
• Every article/source mentioned in the paper and used in your study should be referenced and have an entry.

Writing Center

The Liberty University Writing Center is available to provide writing coaching to students. Residential students should contact the  On-Campus Writing Center  for assistance. Online students should contact the  Online Writing Center  for assistance.

General Rules

Liberty University has determined that graduate students will use APA 7’s formatting guidelines for professional papers. To assist you, Liberty University's Writing Center provides a template paper and a  sample paper .

For professional papers, the following four sections are required: 

• Title Page with Running Head
• Abstract with Keywords
• Reference List

Here are a few things to keep in mind as you format your paper:

• Fonts  - LU recommends that papers be typed in 12-point Times New Roman or 11-point Calibri fonts.  
• Use only one space at the end of each sentence in the body of your paper.
• In general, APA papers should be double spaced throughout. A list of exceptions can be found here.
• To make sure that your paper is double spaced throughout,  select the text ,  right click , select ' Paragraph ,' and look under the section ' Line Spacing ' as shown below:

• Margins/Alignment  - Your paper should use 1-inch margins on standard-sized paper (8.5' X 11'). Make sure that you use  Align Left  (CTRL + L) on the paper, except for the title page.  
•   Indentation – The first sentence in each new paragraph in the body of the paper should be indented a half inch. The abstract, however, should not be indented. References use hanging indentation .  
• Headings:   Please note that all headings are in title case. Level 1 headings should be centered (and in bold), and Level 2 and 3 headings should be left-aligned (and in bold or bold italic, respectively). Level 4 and 5 headings are indented like regular paragraphs. An example of formatting headings in a paper is available here

Title Page: When setting up the professional title page, please note the following elements should be present on the page:

• There is no limit to the number of words in the title.
• Add an extra blank double-spaced line between the title and author’s name.
• Name of each author (centered)
• Name of department and institution/affiliation (centered)
• Place the author note in the bottom half of the title page. Center and bold the label “Author Note.” Align the paragraphs of the author note to the left. For an example, see the LU Writing Center template for graduate students here .
• Page number in top right corner of the header, starting with page 1 on the title page
• The running head is an abbreviated version of the title of your paper (or the full title if the title is already short).
• Type the running head in all-capital letters.
• Ensure the running head is no more than 50 characters, including spaces and punctuation.
• The running head appears in the same format on every page, including the first page.
• Do not use the label “Running head:” before the running head.
• Align the running head to the left margin of the page header, across from the right-aligned page number.

Abstract Page: The abstract page includes the abstract and related keywords.

The abstract is a brief but comprehensive summary of your paper. Here are guidelines for formatting the abstract:

• It should be the second page of a professional (graduate level) paper.
• The first line should say “Abstract” centered and in bold.
• The abstract should start one line below the section label.
• It should be a single paragraph and should not be indented.
• It should not exceed 250 words.

Keywords are used for indexing in databases and as search terms. Your keywords should capture the most important aspects of your paper in three to five words, phrases, or acronyms. Here are formatting guidelines:

• Label “ Keywords ” one line below the abstract, indented and in italics (not bolded).
• The keywords should be written on the same line as and one space after the label “ Keywords ”.
• The keywords should be lowercase (but capitalize proper nouns) and not italic or bold.
• Each keyword should be separated by a comma and a space and followed by a colon.
• There should be no ending punctuation.

13.1 Formatting a Research Paper

Learning objectives.

• Identify the major components of a research paper written using American Psychological Association (APA) style.
• Apply general APA style and formatting conventions in a research paper.

In this chapter, you will learn how to use APA style , the documentation and formatting style followed by the American Psychological Association, as well as MLA style , from the Modern Language Association. There are a few major formatting styles used in academic texts, including AMA, Chicago, and Turabian:

• AMA (American Medical Association) for medicine, health, and biological sciences
• APA (American Psychological Association) for education, psychology, and the social sciences
• Chicago—a common style used in everyday publications like magazines, newspapers, and books
• MLA (Modern Language Association) for English, literature, arts, and humanities
• Turabian—another common style designed for its universal application across all subjects and disciplines

While all the formatting and citation styles have their own use and applications, in this chapter we focus our attention on the two styles you are most likely to use in your academic studies: APA and MLA.

If you find that the rules of proper source documentation are difficult to keep straight, you are not alone. Writing a good research paper is, in and of itself, a major intellectual challenge. Having to follow detailed citation and formatting guidelines as well may seem like just one more task to add to an already-too-long list of requirements.

Following these guidelines, however, serves several important purposes. First, it signals to your readers that your paper should be taken seriously as a student’s contribution to a given academic or professional field; it is the literary equivalent of wearing a tailored suit to a job interview. Second, it shows that you respect other people’s work enough to give them proper credit for it. Finally, it helps your reader find additional materials if he or she wishes to learn more about your topic.

Furthermore, producing a letter-perfect APA-style paper need not be burdensome. Yes, it requires careful attention to detail. However, you can simplify the process if you keep these broad guidelines in mind:

• Work ahead whenever you can. Chapter 11 “Writing from Research: What Will I Learn?” includes tips for keeping track of your sources early in the research process, which will save time later on.
• Get it right the first time. Apply APA guidelines as you write, so you will not have much to correct during the editing stage. Again, putting in a little extra time early on can save time later.
• Use the resources available to you. In addition to the guidelines provided in this chapter, you may wish to consult the APA website at http://www.apa.org or the Purdue University Online Writing lab at http://owl.english.purdue.edu , which regularly updates its online style guidelines.

General Formatting Guidelines

This chapter provides detailed guidelines for using the citation and formatting conventions developed by the American Psychological Association, or APA. Writers in disciplines as diverse as astrophysics, biology, psychology, and education follow APA style. The major components of a paper written in APA style are listed in the following box.

These are the major components of an APA-style paper:

Body, which includes the following:

• Headings and, if necessary, subheadings to organize the content
• In-text citations of research sources
• References page

All these components must be saved in one document, not as separate documents.

The title page of your paper includes the following information:

• Title of the paper
• Author’s name
• Name of the institution with which the author is affiliated
• Header at the top of the page with the paper title (in capital letters) and the page number (If the title is lengthy, you may use a shortened form of it in the header.)

List the first three elements in the order given in the previous list, centered about one third of the way down from the top of the page. Use the headers and footers tool of your word-processing program to add the header, with the title text at the left and the page number in the upper-right corner. Your title page should look like the following example.

The next page of your paper provides an abstract , or brief summary of your findings. An abstract does not need to be provided in every paper, but an abstract should be used in papers that include a hypothesis. A good abstract is concise—about one hundred fifty to two hundred fifty words—and is written in an objective, impersonal style. Your writing voice will not be as apparent here as in the body of your paper. When writing the abstract, take a just-the-facts approach, and summarize your research question and your findings in a few sentences.

In Chapter 12 “Writing a Research Paper” , you read a paper written by a student named Jorge, who researched the effectiveness of low-carbohydrate diets. Read Jorge’s abstract. Note how it sums up the major ideas in his paper without going into excessive detail.

Write an abstract summarizing your paper. Briefly introduce the topic, state your findings, and sum up what conclusions you can draw from your research. Use the word count feature of your word-processing program to make sure your abstract does not exceed one hundred fifty words.

Depending on your field of study, you may sometimes write research papers that present extensive primary research, such as your own experiment or survey. In your abstract, summarize your research question and your findings, and briefly indicate how your study relates to prior research in the field.

Margins, Pagination, and Headings

APA style requirements also address specific formatting concerns, such as margins, pagination, and heading styles, within the body of the paper. Review the following APA guidelines.

Use these general guidelines to format the paper:

• Set the top, bottom, and side margins of your paper at 1 inch.
• Use double-spaced text throughout your paper.
• Use a standard font, such as Times New Roman or Arial, in a legible size (10- to 12-point).
• Use continuous pagination throughout the paper, including the title page and the references section. Page numbers appear flush right within your header.
• Section headings and subsection headings within the body of your paper use different types of formatting depending on the level of information you are presenting. Additional details from Jorge’s paper are provided.

Begin formatting the final draft of your paper according to APA guidelines. You may work with an existing document or set up a new document if you choose. Include the following:

• Your title page
• The abstract you created in Note 13.8 “Exercise 1”
• Correct headers and page numbers for your title page and abstract

APA style uses section headings to organize information, making it easy for the reader to follow the writer’s train of thought and to know immediately what major topics are covered. Depending on the length and complexity of the paper, its major sections may also be divided into subsections, sub-subsections, and so on. These smaller sections, in turn, use different heading styles to indicate different levels of information. In essence, you are using headings to create a hierarchy of information.

The following heading styles used in APA formatting are listed in order of greatest to least importance:

• Section headings use centered, boldface type. Headings use title case, with important words in the heading capitalized.
• Subsection headings use left-aligned, boldface type. Headings use title case.
• The third level uses left-aligned, indented, boldface type. Headings use a capital letter only for the first word, and they end in a period.
• The fourth level follows the same style used for the previous level, but the headings are boldfaced and italicized.
• The fifth level follows the same style used for the previous level, but the headings are italicized and not boldfaced.

Visually, the hierarchy of information is organized as indicated in Table 13.1 “Section Headings” .

Table 13.1 Section Headings

A college research paper may not use all the heading levels shown in Table 13.1 “Section Headings” , but you are likely to encounter them in academic journal articles that use APA style. For a brief paper, you may find that level 1 headings suffice. Longer or more complex papers may need level 2 headings or other lower-level headings to organize information clearly. Use your outline to craft your major section headings and determine whether any subtopics are substantial enough to require additional levels of headings.

Working with the document you developed in Note 13.11 “Exercise 2” , begin setting up the heading structure of the final draft of your research paper according to APA guidelines. Include your title and at least two to three major section headings, and follow the formatting guidelines provided above. If your major sections should be broken into subsections, add those headings as well. Use your outline to help you.

Because Jorge used only level 1 headings, his Exercise 3 would look like the following:

Citation Guidelines

In-text citations.

Throughout the body of your paper, include a citation whenever you quote or paraphrase material from your research sources. As you learned in Chapter 11 “Writing from Research: What Will I Learn?” , the purpose of citations is twofold: to give credit to others for their ideas and to allow your reader to follow up and learn more about the topic if desired. Your in-text citations provide basic information about your source; each source you cite will have a longer entry in the references section that provides more detailed information.

In-text citations must provide the name of the author or authors and the year the source was published. (When a given source does not list an individual author, you may provide the source title or the name of the organization that published the material instead.) When directly quoting a source, it is also required that you include the page number where the quote appears in your citation.

This information may be included within the sentence or in a parenthetical reference at the end of the sentence, as in these examples.

Epstein (2010) points out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Here, the writer names the source author when introducing the quote and provides the publication date in parentheses after the author’s name. The page number appears in parentheses after the closing quotation marks and before the period that ends the sentence.

Addiction researchers caution that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (Epstein, 2010, p. 137).

Here, the writer provides a parenthetical citation at the end of the sentence that includes the author’s name, the year of publication, and the page number separated by commas. Again, the parenthetical citation is placed after the closing quotation marks and before the period at the end of the sentence.

As noted in the book Junk Food, Junk Science (Epstein, 2010, p. 137), “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive.”

Here, the writer chose to mention the source title in the sentence (an optional piece of information to include) and followed the title with a parenthetical citation. Note that the parenthetical citation is placed before the comma that signals the end of the introductory phrase.

David Epstein’s book Junk Food, Junk Science (2010) pointed out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Another variation is to introduce the author and the source title in your sentence and include the publication date and page number in parentheses within the sentence or at the end of the sentence. As long as you have included the essential information, you can choose the option that works best for that particular sentence and source.

Citing a book with a single author is usually a straightforward task. Of course, your research may require that you cite many other types of sources, such as books or articles with more than one author or sources with no individual author listed. You may also need to cite sources available in both print and online and nonprint sources, such as websites and personal interviews. Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.2 “Citing and Referencing Techniques” and Section 13.3 “Creating a References Section” provide extensive guidelines for citing a variety of source types.

Writing at Work

APA is just one of several different styles with its own guidelines for documentation, formatting, and language usage. Depending on your field of interest, you may be exposed to additional styles, such as the following:

• MLA style. Determined by the Modern Languages Association and used for papers in literature, languages, and other disciplines in the humanities.
• Chicago style. Outlined in the Chicago Manual of Style and sometimes used for papers in the humanities and the sciences; many professional organizations use this style for publications as well.
• Associated Press (AP) style. Used by professional journalists.

References List

The brief citations included in the body of your paper correspond to the more detailed citations provided at the end of the paper in the references section. In-text citations provide basic information—the author’s name, the publication date, and the page number if necessary—while the references section provides more extensive bibliographical information. Again, this information allows your reader to follow up on the sources you cited and do additional reading about the topic if desired.

The specific format of entries in the list of references varies slightly for different source types, but the entries generally include the following information:

• The name(s) of the author(s) or institution that wrote the source
• The year of publication and, where applicable, the exact date of publication
• The full title of the source
• For books, the city of publication
• For articles or essays, the name of the periodical or book in which the article or essay appears
• For magazine and journal articles, the volume number, issue number, and pages where the article appears
• For sources on the web, the URL where the source is located

The references page is double spaced and lists entries in alphabetical order by the author’s last name. If an entry continues for more than one line, the second line and each subsequent line are indented five spaces. Review the following example. ( Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.3 “Creating a References Section” provides extensive guidelines for formatting reference entries for different types of sources.)

In APA style, book and article titles are formatted in sentence case, not title case. Sentence case means that only the first word is capitalized, along with any proper nouns.

Key Takeaways

• Following proper citation and formatting guidelines helps writers ensure that their work will be taken seriously, give proper credit to other authors for their work, and provide valuable information to readers.
• Working ahead and taking care to cite sources correctly the first time are ways writers can save time during the editing stage of writing a research paper.
• APA papers usually include an abstract that concisely summarizes the paper.
• APA papers use a specific headings structure to provide a clear hierarchy of information.
• In APA papers, in-text citations usually include the name(s) of the author(s) and the year of publication.
• In-text citations correspond to entries in the references section, which provide detailed bibliographical information about a source.

• Do not use full justification for student papers.
• Do not insert hyphens (manual breaks) in words at the end of line. However, it is acceptable if your word-processing program automatically inserts breaks in long hyperlinks (such as in a DOI or URL in a reference list entry).
• Indent the first line of each paragraph of text 0.5 in . from the left margin. Use the tab key or the automatic paragraph-formatting function of your word-processing program to achieve the indentation (the default setting is likely already 0.5 in.). Do not use the space bar to create indentation. 
• There are exceptions for the  title page ,  section labels ,  abstract ,  block quotations ,  headings ,  tables and figures ,  reference list , and  appendices .

Paper Elements

Student papers generally include, at a minimum: 

• Title Page (2.3)
• Text (2.11)
• References  (2.12)

Student papers may include additional elements such as tables and figures depending on the assignment. So, please check with your teacher!

Student papers generally  DO NOT  include the following unless your teacher specifically requests it:

• Running head
• Author note

For complete information on the  order of pages , see the APA Style website.

Number your pages consecutively starting with page 1. Each section begins on a new page. Put the pages in the following order:

• Page 1: Title page
• Page 2: Abstract (if your teacher requires an abstract)
• Page 3: Text 
• References begin on a new page after the last page of text
• Footnotes begin on a new page after the references (if your teacher requires footnotes)
• Tables begin each on a new page after the footnotes (if your teacher requires tables) 
• Figures begin on a new page after the tables (if your teacher requires figures)
• Appendices begin on a new page after the tables and/or figures (if your teacher requires appendices)

Sample Papers With Built-In Instructions

To see what your paper should look like, check out these sample papers with built-in instructions.

APA Style uses five (5) levels of headings to help you organize your paper and allow your audience to identify its key points easily. Levels of headings establish the hierarchy of your sections just like you did in your paper outline.

APA tells us to use "only the number of headings necessary to differentiate distinct section in your paper." Therefore, the number of heading levels you create depends on the length and complexity of your paper.

See the chart below for instructions on formatting your headings:

General Formatting Guidelines

Follow these guidelines throughout your paper:

• Double space text
• Header for student and professional papers includes the page number in the upper right hand corner
• Single space after ending punctuation
• Font size and style: Times New Roman 12 pt, Arial 11 pt, Calibri 11 pt, or Georgia 11 pt
• Use the same font type and size throughout the paper (exceptions for figure images, computer code, and footnotes - see 2.19 in APA Manual)
• Margins: 1 inch on all sides
• Left align paragraphs and leave ragged (uneven) margins on the right
• Indention: use 0.5 inch indention for the first line of every paragraph (use tab key for consistency)

Formatting Title Page

The 7th edition Publication Manual for APA introduced the student and professional papers. The major difference between these two types of papers is found on the title page. Please, see the guidelines below for formatting the title page of your document. Also note, follow your professors' guidelines for formatting the title page.

General Title Page Guidelines:

• Double space
• The title should summarize the main idea and be focused/succinct (avoid unnecessary words)
• Title written in title case (the first letter of each word is capitalized), bold, centered, and positioned in the upper half of the title page
• Use the author(s) first name, middle initial, and last name as the author's byline

Student Papers:

• title of the paper
• name of the author(s)
• author affiliation (department and institution name)
• course number and name 
• instructor name
• assignment due date (i.e. November 4, 2020)
• page number (in the header)

Professional Papers:

• author affiliation
• author note
• running head (abbreviated title) - Flush with left margin and written in all capital letters

Formatting Headings

Follow this format for headings (see 2.27 of the Publication Manual for additional details):

Level 1 headings are written in bold title case and aligned to the center. The text begins as a new paragraph.

Level 2 headings are written in bold title case and aligned flush to the left. The text begins as a new paragraph.

Level 3 headings are written in bold, italicized title case, and aligned flush to the left. The text begins as a new paragraph.

Level 4 headings are written in bold title case, indented from the left, and end with a period. The text begins after the period and continues like a regular paragraph.

Level 5 headings are written in bold, italicized title case, indented from the left, and end with a period. The text begins after the period and continues like a regular paragraph.

Formatting Reference List

The following are guidelines for formatting your reference list:

• Start on a new page after the last page of text
• Label the page Reference(s) with a capitalized R, written in bold and centered
• Double space all entries
• Use hanging indent for reference entries (first line of the reference is flush with left margin, subsequent lines are indented 0.5 inches)
• Order alphabetically (see chapter 9 section 44-49 for additional instructions on entry order)

APA recommends using 12-point Times New Roman font. If not using Times New Roman, then another serif typeface should be used for its readability. Only use different typeface in figure descriptions to add style to the paper (section 8.03).

Line Spacing & Margins

Use double-spacing throughout the entire paper.To add double-spacing in Microsoft Word, highlight all the text you want double-spaced, then click on Page Layout . Next to the word Paragraph click on the arrow. Under Spacing , Line Spacing , select Double and then click OK .

Put two spaces after the period for each sentence in the body of the paper (Note, use only one space after a period in your references at the end of the paper) . Microsoft Word does not have a setting to automatically put in two spaces at the end of a sentence, but you can set-up the grammar check to alert you when only one space is used. In Word 2007, click on File, then click Options. Next, click on Proofing. Under When correcting spelling and grammar in Word , click on Settings. Next to Spaces required between sentences , change the setting to 2. Click OK to exit. This setting will alert you to single spaces after a period with the green squiggle that shows when there is a grammar error in your paper.

Leave 1 in. margins from top to bottom and side to side. Microsoft Word usually is set to 1 in. margins. You can check this by clicking on Page Layout , then click on Margins. The margin you are using is highlighted, select Normal if it is not already selected. 

Video How-To for Other Popular Applications

Sample Paper

The title page of an APA paper includes a shortened version of your title in the header, with the words: Running head: before it. The shortened title needs to make sense, it is not simply the first 50 characters of the longer title. The running head is on the left, on the right is the page number, starting with 1. Centered on the page is the full title of the paper, the author's name is on the next line, and the institutional affiliation (your school) is on the third line.

If your professor requires an abstract, you will include a summary of your paper on the second page. Start the abstract on a new page. Type the word Abstract on the center top of the page. Include page number and shortened title in the header. You no longer need to type the words

Running head:

before the title. The abstract is typed without any indentation.

Finally, we begin to type the paper! The full title starts it off at the top center of a new page. For the rest of the paper, you only need the title and page numbers in the header. Remember to cite!

APA Research Paper Template

Below is a template you can use every time you need to set-up a research paper using APA style format. Simply open the template and type your own information every time you need to write an APA style research paper. Microsoft Word 2013 will allow you to save personal templates. Once you have the template opened in Word

Click "Save as"

Give the file a name

Under "Save as type", select Word Template

Then when you open Word 2013, you will be able to choose a template rather than a blank document. You might have to select Personal to find your template.

Number of Spaces after a Period

APA style recommends placing two spaces after a period that ends a sentence. This rule is often not enforced by professors. The reasoning behind it is to aid in proofreading. You can read more about it in the APA Style Handbook on pages 87-88. Microsoft Word 2010 and later editions does not allow the user to put in two spaces after a period in any automatic way. You can set-up your grammar check to alert you when you have failed to place two spaces after a period. To do this, go to File-Options-Proofing-Writing Style-Grammar-Settings. In Spaces Required Between Sentences, select 2. Now when you type your paper and insert only one space after a period, you will see a small green squiggly where you fail to put in two spaces, once you do a grammar check of your paper. Keep in mind that APA does not call for two spaces after any period (such as for abbreviations or in the reference list) ONLY when a period ends a sentence do you need two spaces.

How to format a research paper step by step

Discover many styles for producing your research paper, how to correctly arrange and format your research paper in this easy-to-read article.

Whatever form of research you conduct, if you are writing a paper, an outline will help you organize your thoughts and also serve as a model for the rest of your work.

A research paper’s layout should not take longer than the research itself and should aid in making it visually simpler to read. A research paper outline acts as a visual reminder to include all important parts of your chosen subject. It’s simply a skeleton version of the actual document that you can utilize throughout the writing process. 

Understanding the many styles and structures that you may use to outline your research paper will help you learn how to format a research paper properly. This guide will walk you through the steps and help you complete them more quickly.

Research Paper Structure

Before understanding and learning how to format a research paper, it is critical to comprehend the proper structure and how to write it appropriately.

Your research paper, like any other paper you produce, requires a cover page with the title of your study. It also requires the names and institutional affiliations of you and any co-writers.

Introduction

The introduction part informs the reader about the problem that your research is aiming to tackle. You can also discuss the study’s importance and uniqueness here. In the form of a thesis statement, clearly define the research question.

You can learn more about How to write an introduction for a research paper in our recent article.

Background Information

In the background section, you might provide historical facts or clarify previous theories that provide context for your research. It’s also an excellent place to discover your audience and what information they’ll need to understand the rest of your piece.

Literature Review

The literature review part takes research papers or books from the background section and examines them in further depth.

Understanding your study requires knowing if you utilized qualitative or quantitative methodologies. You can mention all of the methods you used to obtain data, such as experiments, surveys, or research.

What conclusions has your research drawn? In this area, you should present your results and data. Use an objective viewpoint here; leave the evaluation until your closing section, the conclusion.

In conclusion, explain why your findings are noteworthy. This part allows you to assess your outcomes and reflect on your process.

We also have an article in the blog about How to Write a Conclusion for a Research Paper .

Reference Page

The reference list includes information for readers who want to access the sources you cited in your work. Your reference page is located at the bottom of your article.

Make sure to mention all of the used references in the proper citation format; there are many formats presently in use, such as MLA and APA, which, while similar, rely on distinct citation styles that must be followed consistently.

How to format a research paper

General formatting.

• If you’re working on a printed research paper, make sure to use clean, good quality 8 1/2′′ x 11′′ white paper,  only printed on one side. 
• Leave 1-inch margins on the top, bottom, left, and right edges of each page of your essay. 
• Page numbers, which are flushed to the right margin, are set 1/2 inch from the top upper-right hand corner; arabic numerals must be used for page numbers and they should not be decorated in any way.
• The letters are centered on this double-spaced page.
• Each word’s first letter should be capitalized, except for extremely short phrases such as prepositions or articles.
• Add the name of your institution, college, or high school. 
• Enter your research paper title, including a subtitle if applicable, about one-third of the way down the page.
• After skipping a few lines, enter your name, course name and number, instructor name, and paper due date, when applicable.

Some formats may not require an abstract; check with your format style to see whether it is required.

• Start a new page.
• The abstract page should include the page header.
• Center and bold the word “Abstract” on the first line of the abstract page (no italics, underlining, or quotation marks). 
• Your study subject, research questions, participants, methodology, findings, data analysis, and conclusions should all be included in your abstract.
• Your abstract should be one paragraph long and double-spaced. Typically, your abstract should be no more than 250 words long. 
• In some styles, such as AMA, you should also incorporate keywords from your article in your abstract. Start a new paragraph, then type Keywords: (italicized), followed by a list of your keywords.

• The entire research should have double spacing between lines.
• One space should be left between words and one space after each comma, semi-colon, or colon. 
• A space should never be placed in front of a punctuation mark.

A quote’s specific format is determined by its length and the research style applied. It is vital to avoid plagiarism by quoting and referencing sources correctly.

Writing Research Papers

• Formatting Research Papers

Research papers written in APA style should follow the formatting rules specified in the Publication Manual of the American Psychological Association .  Most research papers that are written for psychology courses at UCSD, including the B.S. Degree Research Paper and the Honors Thesis, have to follow APA format.  Here we discuss the formatting of research papers according to APA style.

How to Format a Research Paper in APA Style

For the most accurate and comprehensive information on formatting papers in APA style, we recommend referring directly to the Publication Manual of the American Psychological Association. Reputable online sources (e.g., the official APA Style website and the Purdue University Online Writing Lab’s guide to APA style) are also recommended. 

According to the Publication Manual, the major sections and components of APA style research papers should adhere to the following guidelines.  Note that how closely these guidelines are followed may vary depending on the course and instructor.  

General Formatting Rules

• Papers should have at least 1-in. margins on all sides. 1
• All text should be double spaced . 1
• Times New Roman, 12 point font is preferred. 1
• All lines of text should be flush-left and should not be justified, except where noted in the Manual. 1
• The first line of every paragraph should be indented. Exceptions to the indenting rule are the Abstract, quotations, titles and headings, as well as Tables and Figures. 1
• Pages should be numbered at the top right, with the title page numbered page 1, the Abstract numbered page 2, and the text starting on page 3. 1
• An abbreviated title called the Running Head should be placed at the top of each page, flush-left in uppercase letters. 1
• Two spaces should be used after punctuation marks at the end of each sentence (in other words, there should be two spaces after the period that ends each sentence). 2

Formatting the Title Page

• The title should be typed in the upper half of the title page, centered, and with the first letters of all but minor words capitalized. 3
• The name(s) of the author(s) should be typed below the title and followed with the institutional affiliation(s) of the author(s). 3
• An Author Note should appear below the aforementioned items. The Author Note can have up to four paragraphs.  These respectively describe the author(s)’ departmental and institutional affiliation, any changes in affiliation, acknowledgments, and contact information. 3

Formatting the Abstract

• The Abstract typically should not exceed 250 words. 4
• The Abstract should be placed on a separate page, with the label Abstract appearing at the top center of that page and followed by the text of the Abstract. 4
• The Abstract should not be indented. 4

Formatting the Main Body of Text

• The main body of text should begin on a separate page after the Abstract. 5
• It should begin with the Introduction section. 5
• The Introduction section should be titled with the title of the research paper and not the word “Introduction.” The title should appear at the top of the page, centered, and should not be bolded. 5
• The remainder of the text should be flush-left, with each new paragraph indented except where noted above (see General Formatting Rules ). 5
• Each of the subsequent sections of the paper should be prefaced with a heading. APA guidelines specify different heading formats (for more information on Levels of Headings , see below). 5

Formatting References

• The references section should begin on a separate page after the main body of text. 6
• It should begin with the word “References” placed at the top of the page and centered. 6
• All references should be listed in alphabetical order by the last name of the first author of each reference. 6
• All references should be double-spaced and should use a hanging indent format wherein the first line of each reference is flush-left and all subsequent lines of that reference are indented (with that pattern repeating for each reference). 6
• All references should use the appropriate APA reference format (for more information, please see the Citing References section of this website). 6

Levels of Headings in APA Style

As of the sixth edition of the Publication Manual of the American Psychological Association (released in 2010), the five possible levels of heading in APA-formatted manuscripts are: 7

• Level 1: centered, bold, on a separate line, and the first letters of all but minor words capitalized.
• Level 2: flush-left, bold, on a separate line, and the first letters of all but minor words capitalized.
• Level 3: indented, bold, as a paragraph heading (the first part of a paragraph; regular text follows on the same line), and in lowercase letters ending with a period.
• Level 4: indented, bold, italicized, as a paragraph heading (the first part of a paragraph; regular text follows on the same line), and in lowercase letters ending with a period.
• Level 5: indented, not bold, italicized, as a paragraph heading (the first part of a paragraph; regular text follows on the same line), and in lowercase letters ending with a period.

Depending on the structure of your research paper, some or all of the five levels of headings may be used.  The headings have a “hierarchical nested structure” where Level 1 is the highest and Level 5 is the lowest.  For example, you may have a research paper which uses all five levels of heading as follows:

Double-Spacing Demystified: The Research Paper Format

Double-spacing research papers has been an academic standard for centuries, but with the advent of computers and digital writing tools, this practice is being called into question. This article examines the long history of double spacing as a format in scholarly works and delves into the current debate over its merits or detriments to students’ understanding and progress. It then explores potential solutions to address any concerns related to writing styles when it comes to submitting assignments that require certain formatting conventions such as double-spacing research papers. Finally, readers will gain insight on how best practices can be adopted while considering different perspectives from faculty members about proper presentation within their coursework.

I. Introduction

A. definition of double-spacing, b. history of the research paper format, ii. benefits and drawbacks of double-spacing, a. improving readability in longer papers, b. potential layout issues with printed copies, iii. guidelines for properly formatted texts a) spacing between paragraphs b) indentation settings c) font size specifications d) page numbering conventions iv . considerations for non-traditional formats a). bullet point lists b). charts, graphs, and tables v . conclusion vi . references vii . appendix.

It is an undeniable fact that the quality of a research paper can make or break its success. To ensure that your work stands out among others, it is important to pay attention to all aspects of writing and presentation – from styling to spacing. This article seeks to answer the question: are research papers double spaced?

• The short answer is yes.
• While many modern-day formats allow for single spacing in some places, such as within tables or figures, text throughout should always be double-spaced.

Double-spacing allows readers more room between lines; thus making it easier on their eyes when reading through long passages of text. It also provides room for comments or feedback alongside your work when you submit it for review (whether this be done electronically with track changes turned on). Furthermore, having two spaces ensures better readability by emphasizing key words and phrases within sentences due to greater visual contrast between them and surrounding information. All these factors are essential in ensuring clarity throughout academic documents.

Double-spacing refers to the amount of white space a writer leaves between lines of text in an article, essay, or paper. It’s most often used when writing papers for school and professional documents. The standard double spacing convention calls for inserting two spaces after punctuation marks such as periods and commas, question marks, exclamation points, and quotation marks.

• Typically each line should be left blank at least twice the length of the font size being used.

For example , if one is using 12pt Times New Roman font then there should be 24 points (2 x 12) left blank between every line. This allows ample room for editing later on while also providing readers with enough breathing room to easily read through all sections without becoming overwhelmed by too much information on one page.

Additionally some classes require specific styles such as APA style that dictate whether research papers must be double spaced or not. Although this varies from class to class; it is generally safe practice to format any paper according to whichever guidelines are provided by your professor/instructor regardless if you are instructed specifically about single vs double spacing or not..

The concept of the research paper has been in existence for centuries. The earliest known work, a brief written by Leonard of Pisa, can be traced back to 13th-century Italy. Since then, the format and style of writing have developed over time as technology and literacy rates have evolved.

In modern times, it is common practice that research papers should be double spaced . This allows readers to more easily identify key points within each paragraph without having to strain their eyesight or search through lines of text too close together. Additionally, margins are usually set at 1 inch all around so that ample room is provided for comments from instructors while grading student papers. Finally most often research papers include titles or subtitles which act as organizational tools within a document.

The use of double-spacing between lines in academic and business documents has both benefits and drawbacks. The most common example of this is the standard for student essays, which are often written with a double line space.

• Double-spacing makes text easier to read; it increases the physical space between words, providing enough separation so readers can easily distinguish one word from another. This may be especially important when reviewing dense texts or long reports.
• It also allows plenty of room for writing corrections by hand, such as adding extra information or making changes that would otherwise need to be made on a separate page.

In some cases , the extended amount of white space used by double – spacing can make documents look too long and cause them to take up more pages than necessary . When creating materials intended solely for digital delivery , having shorter sections reduces scrolling time , improving usability .

Double – spaced papers also reduce formatting options available for text because there is less flexibility with regard to font sizes , typefaces , margins etc. For instance, research papers should always be single spaced due to their complexity; they require tighter line spacing so all relevant information fits together properly without taking up too much real estate on each page . .

When writing longer papers, readability should be a primary concern. There are several steps that authors can take to ensure readers don’t become overwhelmed with the material.

• For starters, incorporate white space into your paper by adding extra line breaks between sections or using bulleted and numbered lists where appropriate.
• As well, use shorter sentences throughout instead of overly long and complex ones.

Clarity Is Key Printing a document can often bring out formatting problems that weren’t evident before. Careful examination of all elements such as font size and style, spacing between words and paragraphs, indentation for bullet points or lists, table cell widths etc., is necessary to ensure clarity on the printed page. Alignment issues are also common when printing documents; alignment should be examined carefully in order to maintain an even appearance.

When it comes to research papers especially, there are some layout considerations that may need extra attention. Are research papers double spaced? Should block quotes follow different rules than other text within the paper? And what type of margins will look best while ensuring no information is cut off from the edges? Ensuring accuracy with these details helps your readers comprehend their contents more easily – making them look professional yet easy-to-read.

Text formatting is an important component of many academic papers, particularly those written in the humanities. Spacing between paragraphs and indentation settings are a key part of this style, as it allows readers to easily differentiate one idea from another. Font size specifications should also be followed carefully, so that ideas can be read clearly without straining the eyes. Additionally, page numbering conventions must also be used appropriately for referencing and citation purposes.

When exploring non-traditional formats such as bullet point lists or charts/graphs/tables, there are certain considerations which should come into play when formatting them correctly. For example; bullets should all contain similar information on each line where applicable (i.e., two different fonts should not both exist within a single list item). Graphs and tables may need additional explanatory text below them if complex calculations have been performed in order to reach their data points – this helps explain how your findings were reached to any reader unfamiliar with mathematics or statistics terms & concepts. Are research papers double spaced? Generally speaking yes: most research paper guidelines stipulate that documents are double spaced by default for ease of reading while still allowing sufficient space for annotations and corrections from instructors etc..

English: With the understanding of how to format a research paper, including double-spacing requirements, students are now well equipped with an essential tool for academic success. Educators should continue to encourage student literacy in best practices when formatting and citing research materials as part of their ongoing educational endeavors. By instilling these standards early on in the educational process, not only will this aid students’ performance but it can also help create lifelong habits that lead to greater scholarly outcomes.

Radiation-induced DNA double-strand breaks in cortisol exposed fibroblasts as quantified with the novel foci-integrated damage complexity score (FIDCS). Sci Rep. 2024 May 6;14:10400. Note:  From the abstract: “Without the protective shielding of Earth’s atmosphere, astronauts face higher doses of ionizing radiation in space, causing serious health concerns. Highly charged and high energy (HZE) particles are particularly effective in causing complex and difficult-to-repair DNA double-strand breaks compared to low linear energy transfer. Additionally, chronic cortisol exposure during spaceflight raises further concerns, although its specific impact on DNA damage and repair remains unknown. This study explorers the effect of different radiation qualities (photons, protons, carbon, and iron ions) on the DNA damage and repair of cortisol-conditioned primary human dermal fibroblasts.” This article may be obtained online without charge.

Acta Astronaut. 2024 May 8. Online ahead of print. Note:  From the abstract: “Lunar exploration has captivated significant attention in recent times through programs such as Artemis. To establish long-term sustenance on the Moon, astronauts have to grow their food on-site. While a key substrate for plant production – lunar regolith can induce baneful effects, supplementation with organic amendments could alleviate this inherent toxicity and significantly improve plant growth. In the present study, we examined the suitability of cocopeat (CP) as an amendment to ISRO’s lunar soil simulant (LSS), LSS-ISAC-1.”

R Soc Open Sci. 2024 May 1;11(5):231906. Note:  From the introduction: “Here, we propose a novel solution: lunar inhabitants could engage in running on the inside of vertical circular walls, hence running parallel to the Moon surface. Such an activity on Earth is reserved for motorized vehicles during stunt exhibitions (called ‘Wall of Death’ (WoD)) but could be done by humans on the Moon and would generate enough centrifugal acceleration to emulate a higher level of gravity. This would provide an exercise-based countermeasure that simultaneously stimulates cardiorespiratory fitness, the musculoskeletal system and motor control. This article provides a theoretical framework for horizontal circular locomotion tests its prediction in a terrestrial Moon gravity emulator and estimates its physiological demands.” This article may be obtained online without charge.

Online ahead of print. Note:  From the abstract: “In this paper we address very briefly the medical issues, but the work is mainly focused on the advantages regarding engineering, operations, life support, safety and budget of having a constantly rotating spacecraft first in Low Earth Orbit and later for long duration missions to Mars. A large rotating spacecraft is feasible and affordable to build, operate and maintain. It has advantages for governmental and commercial use but also in light of the expected increase in space tourism. It will also save crew time and billions of dollars now being spent to counteract the effects of microgravity.”
