I'm looking for a typeface that is easy to read on screen at small sizes (11-14px high). It will be reversed on a colored button and dark gray on a white button. I'm currently considering Whitney Bold, but don't want to drop the cash if it's not going to work at these sizes. Does anyone have a copy of this typeface that would be willing to do a test for me? I need a few representative words typeset in uppercase at 11, 12, 13 and 14 pixels high. Black on white is fine. Ideally the words would be things like "SAVE", "EDIT", "CANCEL" "ADD". I'd really appreciate any help you can give.
Feel free to make suggestions for alternate fonts as well. My primary requirement is that it be a stylistically neutral sans serif that's readable at small sizes. Here's an example of the button set in Kievit Bold. Thanks!
