About IBM Plex Sans

IBM Plex Sans is a sans serif typeface designed by Mike Abbink, Bold Monday, published as an open-source font in 2018. It carries a calm, even rhythm and a composed, professional tone, which shapes where it works best. The family ships 14 styles and is available as a variable font, so any weight in between is available too.

Language support extends beyond basic Latin to cyrillic, cyrillic-ext, greek, latin-ext, vietnamese. Because IBM Plex Sans is licensed under the SIL Open Font License 1.1, you can use it in commercial work without buying anything or crediting anyone in the design itself.

Licence

✓ IBM Plex Sans is free for commercial use

SIL Open Font License 1.1, verified by DaFontFonts

The SIL Open Font License is the most common open font licence. It permits use in any commercial or personal project, print, logos, websites, apps, products for sale, and allows modification and redistribution. The only real restrictions: you may not sell the font files by themselves, and if you modify the font you must rename it (if it uses a Reserved Font Name) and keep it under the OFL.

You can

Commercial use in any project, client work, products for sale, advertising
Logos and brand identities (including trademarked logos)
Web embedding (@font-face) and app embedding
Print: books, packaging, merchandise, print-on-demand
Modifying the font and redistributing modified versions (under the OFL, renamed if a Reserved Font Name applies)

Keep in mind

Selling the font files by themselves (bundling with software or designs is fine)
Modified versions must stay under the OFL and drop any Reserved Font Name
