no comic sans, ever
I received a job description today from a prominent local company. The description is in Comic Sans.
Why do people in business use Comic Sans for official correspondence? Did you want me to laugh and smile at your network administrator requirements?
In addition to looking amateur, Comic Sans is hard to read, as its edges are not uniform.
When choosing a font for a resume, a cover letter, or any document that will represent you or your company, it’s best to err on the side of conservatism. Times New Roman, Courier, Tahoma and Arial are easy to read, both on screen and in print. They give your document a clean, polished, and uniform appearance.
I’m not entirely opposed to working outside of this font set, especially for resumes for graphic designers or other creative professionals. However, use discretion. Make sure that you print out your resume to see how what is on your screen translates to paper. (I can’t reiterate enough how often recruiters/HR folks still print resumes.) If you have the opportunity, try looking at any non-standard font choices on different screens. What may look crisp and beautiful on your Mac at home could be muddy on the hiring manager’s PC.
