The official notes explain how the Roboto shapes were adapted to that constraint: narrow letters such as I, l and i gain serifs to even out the texture, wide letters are adjusted in weight, and round capitals take straighter sides. Characters that matter in source code are kept distinct: the digit 1, lowercase l and capital I differ, zero differs from capital O, curly braces have pronounced points, and full stops and commas are enlarged. The specimen shows the slab-like feet on i, j and l. Roboto Mono is variable in weight from 100 to 700, with seven named weights, each with an italic, 14 styles in total. Its 999 glyphs cover Latin, Cyrillic, Greek and Vietnamese sets. Christian Robertson is credited as designer, and the license is the SIL Open Font License 1.1. ## License SIL Open Font License 1.1.

There is no ExtraBold or Black. - **Two variable files**: Roman and italic are separate files. - **Every character fills a cell**: Because i and l occupy the same width as m and w, a line in Roboto Mono runs longer than the same line in Roboto. ## FAQs ### Is Roboto Mono free for commercial use?
