| Re: Recommended Font Sizes
As PocketRocket says, 3/16" (about 5 mm) is a good general minimum for the denomination. If the contrast between font and background is high, and the font has a high readability, then it could be slightly smaller. If the contrast is low, or the font has a low readability, then the font should be considerably bigger.
Other text could go down to about half the size of the minimum size of the denomination.
As Colquhoun says, the best thing is to try it out. Make a couple of mock ups from a printout and put them in the middle of the table in the lighting you would have at a game. If the denomination is readable while you are seated at the table, the font is adequately sized.
