Futura Font

Jost was explicitly designed as an open-source take on 1920s German geometric sans serifs, so it shares Futura's circular o, pointed A, and single-story a. Its x-height is a bit taller, which makes it more practical for body text than most Futura cuts.

League Spartan revives Spartan, the American answer to Futura, so the geometry and proportions track Futura closely, especially in the bold weights. It is heavier and punchier by default, best for headlines rather than long text.

Didact Gothic has the plain circular geometry and open, schoolbook-style letterforms that sit close to Futura Book. It ships in only one weight, so it works for text settings but not for a full Futura-style hierarchy.

Questrial is a single-weight geometric sans with round counters and minimal stroke contrast, close to a light Futura in feel. It is more open and airy, and the lack of additional weights limits it to display and short-copy use.

Josefin Sans is a geometric sans rooted in the same 1920s vintage, with long elegant ascenders and a small x-height that echo Futura Light. Its lowercase sits lower on the line and feels more decorative, so it reads as vintage rather than strictly modernist.

Poppins applies Futura-style pure-circle geometry to a large x-height and near-monolinear strokes, giving a friendlier, more contemporary result. It is rounder and less severe than Futura, but the geometric DNA is unmistakable.
