Iosevka is an open-source typeface family that combines sans-serif and slab-serif, monospace and quasi-proportional designs. It is built for writing code, working in terminals, and preparing technical documents.
The monospace family is slender by default, with every glyph exactly 1/2em wide. Compared with competing fonts, this lets users fit more columns within the same screen width. Iosevka offers two widths, Normal and Extended, so readers who want more space between characters can choose Extended.
Because terminal emulators have stricter font compatibility requirements, Iosevka includes specialized Term and Fixed families. In these, symbols are narrower to match the column-count model terminals rely on. The Fixed families also disable ligation to improve compatibility in certain environments.
The project offers a wide range of styles, from Thin and Extra Light to Semi Bold, Extra Bold and Heavy, along with Character Variant features. Its quasi-proportional Aile and Etoile families extend the design to non-monospace typesetting, making it suitable for technical documents as well as code.
