In the specimen the letters i, l and r stand on slab-like feet that fill out their fixed cells, the zero is marked inside to separate it from the capital O, and the strokes are even with squared-off ends. The family has seven weights, Thin, ExtraLight, Light, Regular, Medium, SemiBold and Bold, each with an italic that the makers call unexpectedly expressive: 14 static styles and no variable font. Its 1,028 glyphs cover Latin, Latin Extended, Cyrillic and Vietnamese. The credits name Mike Abbink and the foundry Bold Monday, and the name table adds Paul van der Laan and Pieter van Rosmalen.

IBM Plex Mono is not a variable font here. - **Bold is the heaviest weight**: The range ends at Bold 700; there is no ExtraBold or Black. - **Reserved Font Name**: The license notice reserves the name Plex, so a modified version must be released under another name. - **No Greek**: Cyrillic and Vietnamese are covered; Greek is not. ## FAQs ### Is IBM Plex Mono free for commercial use?
