In general, double-space all parts of an APA Style paper, including the abstract; text; block quotations; table and figure numbers, titles, notes; and reference list (including between and within entries). Do not add extra space before or after paragraphs.

Exceptions to double line spacing are as follows:

• Title page: Insert an extra double-spaced blank line between the title and the byline on the title page. For professional papers, also include at least one double-spaced blank line above the author note (student papers do not include author notes). Double-space the rest of the title page.
• Tables: The table body (cells) may be single-spaced, one-and-a-half-spaced, or double-spaced, depending on which is the most effective layout for the information. Double-space the table number, title, and notes.
• Figures: Words within the image part of a figure may be single-spaced, one-and-a-half-spaced, or double-spaced, depending on which is the most effective layout for the information. Double-space the figure number, title, and notes.
• Footnotes: When inserting footnotes with the footnotes function of your word-processing program, use the default font settings (usually single-spaced and a slightly smaller font than the text).
• Displayed equations: It is permissible to apply triple- or quadruple-spacing in special circumstances, such as before and after a displayed equation.
