Fira Code: free monospaced font with programming ligatures

Read in Español | 简体中文 | 日本語 | Português brasileiro

Problem

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.

Solution

Fira Code is a free monospaced font containing 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.

What’s in the box?

Left: ligatures as rendered in Fira Code. Right: same character sequences without ligatures.

Fira Code comes with a huge variety of arrows. Even better: you can make them as long as you like and combine start/middle/end fragments however you want!

Fira Code is not only about ligatures. Some fine-tuning is done for punctuation and frequent letter pairs.

Fira Code comes with a few different character variants (cv01, cv02, etc), stylistic sets (ss01, ss02, etc), and other font features (zero, onum, calt, etc), so that everyone can choose what’s best for them. How to enable

Some ligatures can be altered or enabled using stylistic sets/character variants:

Being a programming font, Fira Code has fantastic support for ASCII/box drawing, powerline, and other forms of console UIs:

Fira Code is the first programming font to offer dedicated glyphs to render progress bars:

In action:

We hope more programming fonts will adopt this convention and ship their own versions.

Unicode coverage makes Fira Code a great choice for mathematical writing:
