What Font to use?

I assume you're talking about a resume. Times is the standard that most people use, but you can use any font as long as it looks professional and is easy to read. I would rank Arial last as it just doesn't look very nice.

Personally, I prefer sans-serif fonts because they're easier on the eyes. I used Calibri for mine and it was fine. It's really a matter of preference.

I use Georgia, but it hardly matters.

Georgia seems to be popular among the academics.

I use Times New Roman personally

I like sans-serif too. I use Franklin Gothic Medium. It's main drawback is that its a bit heavy on the bold. But its fine to me.

My friend said he found a study saying Garamond was the best to use, so that's what I use.

Garamond..............or nothing

jester is pretty good. probably the most professional looking. stencil is also nice
