The Anatomy of a Typeface
By FontSide · June 2026
Every typeface is a system of decisions — about stroke contrast, x-height, spacing, and rhythm. The best ones feel invisible: you stop seeing the letters and start hearing the voice behind them. That transparency is the hardest thing to design.
A high x-height opens up the counters and makes small text breathe. Tight tracking pulls a headline together; loose tracking gives a caption room to exhale. None of these choices are accidents — they are arguments about how reading should feel.

The Syne family was originally designed in 2017 for the Art Center "Synesthésie", based in Saint-Denis — a suburb of Paris. The Art Center aims to gather diverse artistic personalities in order to create new and enriching situations. Based on that idea, Syne is an exploration of atypical associations of weights and styles.
Syne Mono is another take on letting go of control. Based on Syne Regular, it has been processed by Bonjour Monde’s DataFace tool, automatically switching on-curve points into off-curve ones and vice-versa.
Checkout the other two members of this heteroclite family: Syne and Syne Tactile.
Syne was conceptualized by Bonjour Monde and designed by Lucas Descroix with the help of Arman Mohtadji. To contribute, see gitlab.com/bonjour-monde/fonderie/syne-typeface
