Spline Sans is a grotesque sans serif typeface family, purpose-built for UI interfaces, checkout processes, and paragraphs of text. Space efficiency is accomplished by condensing traditional grotesque proportions. The cool and restrained tone is accented with strategic "thorn" traps, which blossom into view when set at larger sizes. Spline Sans is an original typeface initiated by the Spline Team , and designed by Eben Sorkin and Mirko Velimirović, with project management by Faride Mereb, testing and design feedback by Gonçalo Teixeira, and concept by Alejandro León. Spline Sans supports an extended Latin glyph set, enabling the typesetting of English, Western, Central and Eastern European languages.

Design starts with a question.
Good letters carry the memory of the pen.
A soft serif with old-style warmth, drawn for display sizes and unhurried reading.
This typeface borrows the melting charm of phototype and rebuilds it, patiently, for the screen.
At text sizes the warmth settles into something quieter: open counters, a generous x-height, and forms that curve rather than cut. It reads like a well-worn paperback — familiar, unhurried, and slightly mischievous.
Good letters carry the memory of the pen.
The brief asked for warmth without nostalgia, and authority without sternness. Spline Sans answered both at once — a face that feels typeset by hand yet holds up at retinal resolutions. At this size it settles into an unhurried rhythm: generous spacing, open counters, and letterforms that carry tone before they announce themselves.
Small sizes are where display faces usually apologise for themselves. Spline Sans does not. Drop into text and the texture tightens into a competent, readable grey — open counters, a generous x-height, and forms that curve rather than cut. At text sizes the warmth settles into something quieter: familiar, unhurried, and slightly mischievous. It reads like a well-worn paperback, holding its voice across captions, footnotes, and long paragraphs without flattening into noise. Paired with a neutral grotesque for wayfinding and labels, it gives an identity system exactly one strong opinion — usually the right number — while the body keeps doing the quiet work underneath.
