Since scanning equipment may differ from company to company, it's best to err on the conservative side when choosing fonts that will be easily read by the software.

 

Therefore, avoid all "designer" fonts that are difficult for a human being to read.  If anything, the scanning software will have even more difficulty.

 

It's best to stick with classic fonts like Arial, which is san serif, or Times New Roman, a popular serif font.  Other good choices are Garamond, Bookman, Courier New, and Century Schoolbook.

 

Font size

Don't make the software work extra hard to read all the characters in your resume, as this may lead to mistakes and missed keywords.  It's best to use a font size between 9 and 12, depending upon the font.
