Is there a font with 3px max width

Question

I would like to feed my led matrix display (with round leds) with a font that uses max. 3 pixel in width per letter.

How would I create such a font, that is still readeable?

I think the biggest problem would be the "w" (but maybe use a trick to the eye for this.)

Answer 1

Why not just use an 8x3 bitmap dataset instead of a real font? Something like a W on an 8x3 can be encoded in a few ways, just add a tiny vertical to act as visual middling (same for M):
