APA (7th Edition) for Word Online

APA requires one inch margins for top, bottom, right, and left. Here is how to check your document's margins in Word Online. One inch margins will usually be selected by default. 

APA papers should be written in a font that is accessible to all users. Historically, sans serif fonts have been preferred for online works and serif fonts for print works; however, modern screen resolutions can typically accommodate either type of font. Use the same font throughout the text of the paper. Options include:

• a sans serif font such as 11-point Calibri, 11-point Arial, or 10-point Lucida Sans Unicode or
• a serif font such as 12-point Times New Roman, 11-point Georgia, or normal (10-point) Computer Modern (the latter is the default font for LaTeX)

APA requires your paper be double-spaced (2.0). From the "Home" tab select the "Paragraph" button. Change the "After" spacing to "0pt" and "Line spacing" to "Double".
