undefined medium

undefined medium is a free and open-source pixel grid-based monospace typeface suitable for programming, writing, and whatever else you can think of … it’s pretty undefined.

It is inspired by many 5×7 pixel grid typefaces, especially Gilles Boccon-Gibod’s MonteCarlo, which is unfortunately, since 2010, no longer maintained.

The 400+ character set fully supports Latin Extended-A with Western European, Central European, and South Eastern European languages.

In addition, there’s many typographic symbols, mathematical symbols, superscripts, double-spaced fractions, a copyleft symbol, and a capital sharp s character.

Thank you very much, Toshi Omagari and David Jonathan Ross, for your advice, guidance, and feedback.



undefined medium is available in OTF and TTF fonts for desktop use, as well as in WOFF and WOFF2 fonts for web projects.

You can download the compiled fonts from the releases section of this repository.
