Iosevka Version Patreon Donate

Coders’ typeface, built from code.

Installation

Quit your editor/program. Unzip and open the folder.

  • Instructions for Windows: Download the fonts from the Releases, select the font files and right click, then hit "Install".
    • 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.
  • Instructions for macOS
    • Standard distribution in Homebrew: brew tap caskroom/fonts && brew cask install font-iosevka (May be outdated).
    • Customizable install using Homebrew: see robertgzr/homebrew-tap.
  • Linux : Copy the TTF files to your fonts directory → Run sudo fc-cache.
    • Arch Linux users can install the font from the AUR here using an AUR wrapper or by doing it manually. All variants.
    • Void Linux users can install the font with xbps-install font-iosevka.
  • FreeBSD: The font can be installed with pkg install iosevka.

Weights, Variants and OpenType features

The typeface contains 9 weights (Thin to Heavy) alongside with both italic and oblique versions, with the same metrics as the regular one.

Weights 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.

Languages Sample

Iosevka supports accessing all letter variants using OpenType features.

Style Sets

Character Variants

Ligations

Ligations Sample

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

Iosevka supports Language-Specific Ligations, which is the ligation set enabled only under certain languages. These ligation sets are assigned to custom feature tags, like XHS0.

Building from Source

To build Iosevka you should:

  1. Ensure that nodejs (≥ 8.4), ttfautohint, otfcc (≥ 0.9.3).
  2. Install necessary libs by npm install. If you’ve installed them, upgrade to the latest.
  3. npm run build -- contents::iosevka.

You will find TTFs, as well as WOFF(2) web fonts and one Webfont CSS in the dist/ directory.

Build Your Own Style

Since version 2.0, Iosevka would no longer support building via makefile. To initialize a custom build, you need:

  1. Create private-build-plans.toml file.

  2. Add a build plan into private-build-plans.toml, following this format:

    [buildPlans.iosevka-custom]            # <iosevka-custom> is your plan name
    family = "Iosevka Custom"              # Font menu family name
    design = ["common styles"]             # Common styles
    upright = ["upright-only", "styles"]   # Upright-only styles
    italic = ["italic-only", "styles"]     # Italic-only styles
    oblique = ["oblique-only", "styles"]   # Oblique-only styles
    
    # Override default building weights
    # When buildPlans.<plan name>.weights is absent
    # All weights would built and mapped to default shape/CSS
    [buildPlans.iosevka-custom.weights.regular]
    shape = 400                            # Weight for glyph shapes
    menu  = 400                            # Weight for menu name
    css   = 400                            # Weight for WebFont CSS
    
    [buildPlans.iosevka-custom.weights.bold]
    shape = 700
    menu  = 700
    css   = 700
    
    # Override default building slant sets
    # Format: <upright|italic|oblique> = <"normal"|"italic"|"oblique">
    # When this section is absent, all slants would be built.
    [buildPlans.iosevka-custom.slants]
    upright = "normal"
    italic = "italic"
    oblique = "oblique"
  3. Run npm run build -- contents::<your plan name> and the built fonts would be avaliable in dist/. Aside from contents::<plan>, other options are:

    1. contents::<plan> : TTF (Hinted and Unhinted), WOFF(2) and Webfont CSS;
    2. ttf::<plan> : TTF;
    3. ttf-unhinted::<plan> : Unhinted TTF only;
    4. woff::<plan> : TTF and WOFF only;
    5. woff2::<plan> : TTF and WOFF2 only;
      • Note: Since version 2.2.0, we are using two colons (::) in the build target names.

The current available styles for design/upright/italic/oblique options are:

  • Styles for general shape:
    • sans : Sans serif (default).
    • slab : Slab serif.
  • Styles related to ligations and spacing:
    • term : Disable ligations and exact monospace.
      • The font built will not contain ligatures.
      • All glyphs wider than one letter would be deleted.
      • In case of your OS or editor cannot handle ligatures correctly, you can disable ligations with it.
    • termlig : Similar to term, the font is exact monospace to make fontconfig happy, while ligations are still present.
    • no-ligation : Disable ligation only.
    • no-cv-ss : Prevent generation of cv## and ss## features.
    • type : Make some symbols, like arrows () full-width.
  • All registered ss## and cv## feature tags, including:
    • ss01~ss10 : Predefined stylistic sets based on other Monospace fonts.
    • cv01~cv53 : Standalone character variants.
  • Styles for ligation sets, include:
    • ligset-haskell: Default ligation set would be assigned to Haskell.
    • ligset-idris: Default ligation set would be assigned to Idris.
    • ligset-coq: Default ligation set would be assigned to Coq.
    • ligset-elm: Default ligation set would be assigned to Elm.
    • ligset-ml: Default ligation set would be assigned to ML.
    • ligset-fs: Default ligation set would be assigned to F#.
    • ligset-fstar: Default ligation set would be assigned to F*.
    • ligset-swift: Default ligation set would be assigned to Swift.
    • ligset-purescript: Default ligation set would be assigned to PureScript.
  • Styles for further customizing default (calt) ligation sets. When any of these styles present in your configuration, the ligset-* styles would be overridden.
    • calt-clear: Clear the calt ligation set.
    • calt-center-ops: Vertically align some of the operators (like *) to the center position it is before or after a "center" operator (like +);
