F3 marks the transition from utility to humanity. With a medium weight, rounded terminals, and a slightly larger aperture on letters like ‘c’ and ‘e’, F3 is designed for long-form reading: novels, long articles, personal correspondence. It balances warmth with neutrality—neither formal nor casual. Serifs (if included) are soft brackets; sans-serif versions of F3 use a near-uniform stroke width to reduce eye fatigue.
