IBM Plex Sans
IBM Plex™ is an international typeface family designed by Mike Abbink, IBM BX&D, in collaboration with Bold Monday, an independent Dutch type foundry. Plex was designed to capture IBM’s spirit and history, and to illustrate the unique relationship between mankind and machine—a principal theme for IBM since the turn of the century. The result is a neutral, yet friendly Grotesque style typeface that includes a Sans, Sans Condensed, Mono, Serif, and several other styles for several languages , and has excellent legibility in print, web and mobile interfaces. Plex’s three designs work well independently, and even better together. Use the Sans as a contemporary compadre, the Serif for editorial storytelling, or the Mono to show code snippets. The unexpectedly expressive nature of the italics give you even more options for your designs. To contribute, see github.com/googlefonts/plex .

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.

Text settingsGood letters carry the memory of the pen.
The brief asked for warmth without nostalgia, and authority without sternness. IBM Plex 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. IBM Plex 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.
