GFS Didot

GFS Didot is the Greek Font Society's scholarly revival of the Didot types, and the only literal free Didot available — vertical stress and hairline serifs intact rather than approximated. Drawn primarily for Greek, it ships with a matching Latin alphabet built to the same construction, so the modern-face qualities that define the style survive the crossing: a rigid vertical axis, abrupt thick-to-hairline transitions, serifs reduced to fine horizontal strokes.

When a project genuinely needs Didot rather than something Didot-adjacent — fashion mastheads, luxury editorial, high-contrast titling — this is the default free answer. The constraint is range: regular, italic, and bold, with no display cuts tuned for very large settings. Treat it as a faithful text-and-headline Didot, set the hairlines large enough to hold, and do not ask it to carry a full display system.
