APA has a number of rules that your instructor may want you to follow. The following information came from the 6th edition of the APA Handbook. See the page number that follows each style rule for more information. NOTE: Your instructor may prefer slight changes to these rules. Check with your instructor for any variations.
Margins - 1 inch all sides, including top, bottom, left and right (p. 229)

Page Numbers & Running Heads - Include a page header (also known as the "running head") at the top of every page. To create a page header/running head, insert page numbers flush right. Then type the title of your paper in the header flush left using all capital letters. The running head is a shortened version of your paper's title and must be less than 50 characters including spacing and punctuation. (p. 229).
