APA Style (7th ed.)
Manuscripts submitted for publication contain a running head with an abbreviated version of the paper title at the top left corner of every page. Student papers only require a running head when specifically requested by instructors; otherwise, papers submitted for grading do not use a running head (American Psychological Association [APA], 2020, p. 37).
If you need to include a running head in your text, the running head should appear directly across from the page number and will be identical on every page, including the title page (APA, 2020, p. 37). The running head includes the title of the paper in all-capital letters up to a maximum of 50 characters, counting letters, punctuation, and spaces between words, for instance: TITLE OF DOCUMENT IN 50 CHARACTERS (APA, 2020, p. 37). When the title of the paper is over 50 characters, abbreviate the title in a shortened form using the most important words from the original title. For an example of how the running head appears in article manuscripts submitted for publication, please see the APA’s Annotated Professional Sample Paper.
