The APA Style rules for formatting a thesis or dissertation are specific, ranging from the proper font size to the proper margins to the type of paper you should use. Here are 14 formatting tips you should follow when creating your paper.

Tip 1: ABBREVIATIONS. Try to avoid using abbreviations in your paper. However, if you have an abbreviation that's commonly accepted in language and appears in the dictionary, such as AIDS, you may use it.

Tip 2: ALIGNMENT. Always align the text flush left. Do not use the "full justify" setting on your word processor, which spreads the text and aligns it both left and right.

Tip 3: FONT. If using a word processor, stick with a serif font, such as Times New Roman. Use text in a 10- or 12-point size.

Tip 4: HYPHENATION. Do not break and hyphenate words at the end of a line. Instead, leave one line a little short and place the entire word on the next line, or go a couple of characters beyond the right margin to fit the entire word on the line.

Tip 5: INDENTIONS. Indent paragraphs within the main text of the paper one-half inch, if using a computer word processor, or five to seven spaces, if using a typewriter. However, do not indent in the following special circumstances: The abstract, block quotations, figure captions, notes, reference list entries, table titles, and titles or headings.

Tip 6: MARGINS. Use 1-inch margins on all four sides of the paper: Top, bottom, right, and left. Old rules called for some 1.5-inch margins, but those rules no longer are valid.

Tip 7: PAGE NUMBERING. Number almost every page in the paper, including the title page. Place the number in the upper-right corner of the page, and use only Arabic numerals. Place the number "1" on the title page and the number "2" on the abstract page. The main text should start on page number "3". Do not number pages that contain only figures or artwork.

Tip 8: PAPER TYPE. Use standard white, 20-pound bond paper that measures 8.5-by-11 inches. If using a computer, use an inkjet or laser printer to print the paper; if you must use a tractor-feed printer, be sure to remove the pinhole borders from the edges of the paper.

Tip 9: PARENTHESES. Try to limit parentheses to set apart elements that are structurally independent, such as when listing a figure or illustration related to a sentence. If you're enclosing a complete sentence in parentheses, place the punctuation inside the parentheses. If you're enclosing only part of a sentence inside parentheses, leave the punctuation outside the parentheses.

Tip 10: PUNCTUATION. In most instances, use one space after all typical punctuation marks, such as periods, commas, colons, and semicolons. Three exceptions exist to this rule. First, do not use a space after periods inside an abbreviation, such as when using U.S. for United States. Second, do not use a space after a colon in a ratio, such as 3:2. Third, some instructors prefer the old rule of using two spaces after periods that end sentences. If you're using Courier or another mono-space font, APA Style does allow two spaces between sentences, although one is preferred.

Tip 11: SHORT TITLE. A Short Title, which is a two- or three-word summary of the main title, should appear on every page in the top right corner, other than pages that contain only figures or artwork. The Short Title should appear just to the left of the page number.

Tip 12: SLASH MARK. Avoid using slash marks in your paper. For example, instead of writing "red and/or green," write "red, green, or both."

Tip 13: SPACING. Use double spacing throughout the entire paper, unless your instructor specifically requests single spacing in certain circumstances, such as with block quotations.

Tip 14: TITLE. Center the title on the title page, using a mixture of uppercase and lowercase letters. If the title is long enough to require a second line, double space between the lines. After the title, the student's name should appear, followed by the institution for which the paper is being written. If you don't have an institution to include, you may substitute the city and state of the author of the paper. Double space between every line on the title page. The title page should contain the number "1" in the upper right corner.
