NaN Serf Sans
NaN · Hugues Gentile, Fadhl Haqq, Léon Hugues, Jean-Baptiste Morizot, Luke Prowse, Florian Runge · 2025

A humanist sans derived from the NaN Serf skeleton, built for screen text across five scripts and more than 550 languages.
About
Sharing the underlying skeleton of NaN Serf, the design replaces serifs with clean vertical-cut endings and opens up the counters to prioritise rhythm and legibility at text sizes. Five scripts — Latin, Cyrillic, Arabic, Greek and Thai — are included from the outset, covering 482 Latin-based, 49 Cyrillic-based and 33 Arabic-based languages alongside Greek and Thai. Distinctive details such as the flat curves on the /G, /b and /q carry over from Serf, giving the family a consistent character across both subfamilies.
Classification
NaN describe it explicitly as a humanist sans derived from the NaN Serf skeleton, with vertically-cut stroke endings and generous counters optimised for text use on screen.
