Which fonts look best for numeric labels?

[GISServices]

Hello,

I'm in the process of creating a new base map for a public web application, and was wondering which fonts for numeric labels (roads, interstates, etc) look best?  Or, which one(s) do you prefer?  I'm yet to find something that I like in the default font list.

Thanks!

Jesse

Are you talking about the "shields" for street signs and such? Have you looked into creating text symbols?

If you are mixing letters and number, any simple serif font, because they make numbers easier to distinguish (letter l vs number 1). I like Century.
