Inter UI is a free typeface specially designed for user interfaces with focus on high legibility of small-to-medium sized text on computer screens. Inter UI comes in 9 weights from Regular to Black and matched Italics.  The family features a tall x-height to aid in readability of mixed-case and lower-case text. Several OpenType features are provided as well, like contextual alternates that adjusts punctuation depending on the shape of surrounding glyphs, slashed zero for when you need to disambiguate “0” from “o”, tabular numbers, etc.

Inter UI typeface is free for personal and commercial use.
