APA Formatting and Style Guide
Summary: APA (American Psychological Association) is most commonly used to cite sources within the social sciences. This resource, revised according to the 5th edition of the APA manual, offers examples for the general format of APA research papers, in-text citations, endnotes/footnotes, and the reference page. Please use the example at the bottom of this page to cite the Purdue OWL in APA.
General Format
General APA Guidelines
Your essay should be typed, double-spaced on standard-sized paper (8.5" x 11") with 1" margins on all sides. You should use 10-12 pt. Times New Roman font or a similar font.
Include a page header in the upper right-hand of every page. To create a page header, type the first 2-3 words of the title of the paper, insert five spaces, then give the page number.
Major Paper Sections
Your essay should include four major sections: the Title Page, Abstract, Main Body, and References.
Title Page
Your title page should already include the page header (described above). On the first line of the title page flush-left, add a running head. Begin the running head with the words “Running Head” followed by a colon. Then give an abbreviated title of your paper in 50 characters or less in all caps. Note: Remember that the page header will appear on every page of your paper, whereas the running head will only appear on your title page.
In the upper half of the title page, type your full title, your byline (name[s]), and affiliation (university, etc.) centered on separate lines. Your title may take up one or two lines as in the example below:
![This is a sample title page that adheres to the APA style guide. The
paper title is in the top right corner, followed by the page number. A
running head should be placed below the page number line, with the first
three words from the paper title in all caps. Then, the paper's title,
author and university information should be centered roughly 10 spaces
below the running head.](https://webarchive.library.unt.edu/eot2008/20090117022225im_/http://owl.english.purdue.edu/media/jpeg/20071205025515_560.jpg)

Abstract
Begin a new page. Your abstract page should already include the page header (described above). On the first line of the abstract page, center the word “Abstract” (otherwise unformatted, no bold, italics, underlining, or quotation marks).
Beginning with the next line, write a concise summary of the key points of your research. (Do not indent.) The abstract should be a single paragraph double-spaced of less than 120 words.
![This is a sample of an APA abstract. The paper title and page number
should be placed in the upper right-hand corner of the page. The word
abstract should be centered on the first line of the page, followed by the
abstract's written contents.](https://webarchive.library.unt.edu/eot2008/20090117022225im_/http://owl.english.purdue.edu/media/jpeg/20071205030245_560.jpg)
