What font should you use on your resume?

The most common and accepted font for business and professional use is Times New Roman.

• A popular online resume writing service recommends serif fonts (e.g. Times New Roman) for a traditional look, and sans serif fonts (e.g. Arial, Helvetica) for a more contemporary look. Which you choose depends on your personal preference and the job you're applying for.
• Use Century Old Style if you're applying to a "business" job--banks, brokerages, like that. Century Old Style is traditionally the face used for bank advertising.
