Best tiny fonts?

[Tannaidhe]

So, I'm trying to fit a lot of information in a very tiny space on a business card (it's not functioning *as* a business card, don't worry, nor is it going up 'for sale', it's for a personal project XD )

I'm just looking for advice on the smallest/most compact font that is still readable when printed, if anyone has experimented with that.

From puttering through the fonts, Banjoman Bold seems to be nicely readable even at size 4 on my screen, but we all know that doesn't necessarily translate to the printed version.

For anyone that might be curious:
I ended up going with Life Roman at 4.5, and it's perfectly readable (assuming you have good eyesight lol..  it is very tiny; but the font is nice and clear.)

Dongle is also a good font for when you want very tiny clear text.

Best fonts for tiny spaces on biz cards: condensed, sans-serif typefaces of medium weight. This will allow for more letters per space, a tall “x” height (height of the “bowl” of each letter), and is very readable. Technically, serifed fonts are the easiest to read, but when going down to teeny-tiny sizes, even weighted letters are easy on the eye and readable. Hope this helps:)
