Installation

Installing from GitHub Releases

  1. Download your font package from releases.
  1. Quit all your editors / programs.
  2. Unarchive the font package and you will see the font files.
  3. Take actions depending on your OS:
    • Windows: Select the font files and drag into font settings / font control panel page.
      • On Windows 10 1809 or newer, the default font installation is per-user, and it may cause compatibility issues for some applications, mostly written in Java. To cope with this, right click and select “Install for all users” instead. Ref.
    • macOS: Follow instructions here.
    • Linux : Copy the font files to your fonts directory then run sudo fc-cache.

Features

In the official package, Iosevka provides 6 monospace subfamilies (sans-serif and slab-serif, each in the 3 spacings Default, Term and Fixed) and 2 quasi-proportional subfamilies (Aile (sans-serif) and Etoile (slab-serif)). In all the monospace subfamilies, 9 weights (Thin to Heavy), 2 widths (Normal and Extended), and 3 slopes (Upright, Italic and Oblique) are included. In the quasi-proportional subfamilies, the quantity of widths is reduced to 1.

Weights sampleWeights sample

All versions include the same ranges of characters: Latin letters, Greek letters (including Polytonic), some Cyrillic letters, IPA symbols and common punctuations and some symbols. You can check out the full list here.

Stylistic Sets

Monospace Iosevka contains various stylistic sets to change the shape of certain characters. Enabling corresponded OpenType feature to enable.

View list of stylistic sets of Iosevka.

Character Variants

Alongside stylistic sets, Monospace Iosevka can also be configured to cherry-pick variants for each character using OpenType. The variants are shown below. To enable, assign the feature tag to the variant index. For example, setting cv26 to 6 will enable single-storey a.

Caution : Certain software may limit the quantity of OpenType features and drop some of them if the feature list is too long. Please validate your feature configuration to ensure that it worked in your software.

Ligations

Monospace subfamilies support ligations. Iosevka’s default ligation set is assigned to calt feature, though not all of them are enabled by default.

calt off Ligation Off
calt Default setting in text editors
dlig Discretionary ligatures

Iosevka supports Language-Specific Ligations, which is the ligation set enabled only under certain languages. These ligation sets are assigned to custom feature tags. To use them, you need to turn off calt and enable the corresponded feature. The feature list is:

Please note that, due to the complex interactions when forming ligations, cherry-picking ligation groups will require a custom Iosevka build. The instructions could be seen below.

Iosevka
What is this?Iosevka is an open-source typeface family designed for writing code, using in terminals and preparing technical documents. It comes in sans-serif and slab-serif forms, both monospace and quasi-proportional.
Is it a single font or a whole family?A family: the official package has 6 monospace subfamilies (sans-serif and slab-serif, each in Default, Term and Fixed spacings) plus quasi-proportional Aile and Etoile. Monospace cuts span 9 weights, 2 widths and 3 slopes.
Do I need to install anything else to use it?Nothing — as a font it is simply installed and picked in your editor or terminal. Building your own customized variant from source is optional and needs Node.js 16 or newer with the project's verda build runner.
Are there any gotchas when installing it on Windows?Yes — on Windows 10 1809 and newer the default install is per-user, which some applications (mostly Java-based ones) may not pick up. Right-click the font files and choose 'Install for all users' instead.
Does it work beyond Windows, macOS and Linux?Yes — the README also lists packages for the BSDs: FreeBSD installs it with 'pkg install iosevka', and on OpenBSD you can discover Iosevka packages with 'pkginfo -Q iosevka'.
Does it support programming ligatures, and can I turn them off?Yes. Monospace subfamilies ship ligatures controlled through OpenType features: the default set lives in 'calt' (not all groups are enabled by default), discretionary ligatures in 'dlig', plus language-specific sets under custom tags. Cherry-picking individual ligation groups requires building a custom Iosevka.
Can I change the shape of individual characters?Yes — there are stylistic sets and per-character variants enabled as OpenType features; for example, setting 'cv26' to 6 switches to a single-storey 'a'. Caution: some software limits how many OpenType features it keeps, so validate your configuration.
Does it include Chinese, Japanese or Korean glyphs?No — for CJK the README points users to Sarasa Gothic, the same author's companion project. Iosevka's own coverage is Latin, Greek (including Polytonic), some Cyrillic, IPA symbols and punctuation, supporting 248 languages.
Is the project actively maintained?Yes — the repository is not archived and its CI runs daily development builds; the project has been in continuous development since 2015.
