Programmers use a lot of symbols, often encoded with several characters. For the human brain, sequences like ->
, <=
or :=
are single logical tokens, even if they take two or three characters on the screen. Your eye spends a non-zero amount of energy to scan, parse and join multiple characters into a single logical one. Ideally, all programming languages should be designed with full-fledged Unicode symbols for operators, but that’s not the case yet.
Fira Code is an extension of the Fira Mono font containing a set of ligatures for common programming multi-character combinations. This is just a font rendering feature: underlying code remains ASCII-compatible. This helps to read and understand code faster. For some frequent sequences like ..
or //
, ligatures allow us to correct spacing.

(#117)
- Support for IntelliJ-based IDEs (instructions)
- Turned on autohinting
- Added Light weight
- Adjusted rules when vertical centering of

occurs
- Fixed calt table conflicts (
----
would incorrectly render as<!--
) - Added centered

-
,*
and+
(only between lowercase letters, e.g. kebab casevar-name
, pointers*ptr
etc)
Added weights:
- Retina (just slightly heavier than Regular)
- Medium
- Bold
Switched to calt
instead of liga
. You can now “step inside” the ligature in text editors.
Fira Code is now drawn and built in Glyphs 2 app (should improve compatibility).
