Martian Mono


Martian Mono is a younger brother of Martian Grotesk—a variable font that I meticulously crafted for the needs of designers and web developers. Get your free trial on Gumroad.


Martian Mono is a monospaced typeface family consisting of a variable font and 28 styles: Condensed to Wide, Thin to Extra Bold. It’s not a neutral font, but despite this, it remains suitable for reading. Overhanging terminals, a closed aperture, and an almost complete lack of contrast lead to slightly brutal and assertive aesthetics.

The typeface features a tall x-height, and it has vertical metrics which guarantee equal space is present above the cap height and under the baseline. The latter makes this typeface an on-screen workhorse: it is evenly placed on buttons, inputs, lists, and forms. When coupled together, all the above features make Martian Mono a reasonable choice for any user interface design.

Prefer otf file format for macOS, and ttf for Windows.
