The claim ”smallest readable 3x4 font” is a bit confusing. Are there bigger 3x4 fonts?



It's a variable width font, so it can be smaller than a fixed 3x3 font.

For example it chose this (ambiguous) encoding for "o":

--

xx

xx

--

where a bigger 3x4 font could choose the overhigh and wider

-x-

x-x

-x-

Ah, that explains it – thank you.
