Weights, Variants and OpenType features

The typeface contains seven weights (thin, extra-light, light, regular, medium, bold and heavy) alongside with both italic and oblique versions, with the same metrics as the regular one.

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

Iosevka supports accessing all letter variants using OpenType features.

Ligations (Experimental)

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 XHS_.

Building from Source

To build Iosevka you should:

1. Ensure that nodejs (≥ 6.0), ttfautohint, otfcc (≥ 0.4.4) and make are runnable in your terminal.
   • Windows users may need to install MinGW and make *nix utilities accessible (mkdir.exe, cp.exe, cat.exe and rm.exe, in particular) from Command Prompt. Utilities provided by Git for Windows works fine.
2. Install necessary libs by npm install. If you’ve installed them, upgrade to the latest.
3. make.
   • Use make DONTHINT=1 to disable hinting.
   • Use make DONTREF=1 to turn off reference-ify (will increase file size but provide better compatibility).

You will find TTFs in the dist/ directory.

Building the Web Font

The webfonts/ directory is used to build Iosevka for web font uses. To build the web fonts you should:

1. Build Iosevka.
2. Ensure that sfnt2woff and woff2_compress are installed and runnable.
3. Run make web .

The web fonts will be generated into dist/iosevka/web and dist/iosevka-slab/web.

Build Your Own Style

Iosevka comes with several visual styles, however they are inactive using the default build. To build these variants, you should perform custom build:

1. make custom-config [set=<name>] with the parameters listed below to create a configuration. The set=<name> part is optional, it will be set to custom when absent.
2. make custom [set=<name>] to acquire your custom font.
   • make custom-web [set=<name>] is for web fonts.

The first step, make custom-config takes following parameters to set styles of your custom build. All of them are optional, and would default to Iosevka’s default configuration:

• design='<styles>', styles for your custom font set.
• upright='<styles>', styles for uprights only.
• italic='<styles>', styles for italics only.
• oblique='<styles>', styles for obliques only.

You can add arbitary styles for these variables, for example, make custom-config upright='v-l-zshaped v-i-zshaped' && make custom will create a variant with Z-shaped letter l and i for uprights.

The current available styles are:

• Styles for general shape:
  • sans : Sans serif (default).
  • slab : Slab serif. When present, the family of your font would be Iosevka Slab.
• Styles related to ligations
  • term : Disable ligations. When this style is present, the font built will not contain ligatures, and its family name will be set to Iosevka Term. In case of your OS or editor cannot handle ligatures correctly, you can disable ligations with it.
