About Spline Sans Mono

Spline Sans Mono, designed by Eben Sorkin and Mirko Velimirović, is a monospaced companion to the Spline Sans family, carrying over its open, humanist proportions into a fixed-width format. The variable weight axis allows the same font to serve both lightweight code comments and heavy-weight UI labels, reducing font file overhead. It excels in developer tools, code editors, technical documentation, and any interface where monospaced text needs to feel refined rather than utilitarian.
