JetBrains Mono: a typeface made for developers

JetBrains Mono is available as a standalone download, and is also bundled in all JetBrains IDEs. Discover more font features & design on its web page.

Default version of JetBrains Mono comes with OpenType features and ligatures (which can always be toggled on & off in the settings). If your IDE doesn’t support OpenType, use a special version of the font — JetBrains Mono NL, which doesn’t include any ligatures.

Installation

JetBrains IDEs

Brew (macOS only)

1. Tap the font cask to make the Jetbrains Mono font available :

• Chocolate
• ChromeOS terminal

Font Styles

There are 8 font styles available in JetBrains Mono, from Thin to ExtraBold, each coming with its own italic version.

Font Features

Increased x-height

While characters remain standard in width, the height of the lowercase is maximized. This approach keeps code lines to the length that developers expect, and it helps improve rendering in small size, since each symbol occupies more pixels.

Distinctiveness of symbols

Ligatures for Code

A ligature is a character consisting of two or more joined symbols. Traditionally, it was introduced as a space-saving technique in printed texts. In code, this technique is adopted to show operators and is used mainly for two purposes:

1. To reduce noise by merging symbols and removing details so the eyes are processing less:

2. To balance whitespace more efficiently by shifting the glyphs in certain cases:

📝 Note: if your IDE doesn’t support OpenType features and ligatures, use JetBrains Mono NL instead.

Basic Character Set

• install gftools pip install gftools (requires python 3.9.5 or higher on BigSur)
• Navigate to …JetBrainsMono/sources/ in Terminal app.
• Type gftools builder config.yaml in Terminal and run it.

Which font?

TL;DR

• Pick your font family and then select from the 'complete' directory.
  • If you are on Windows pick a font with the 'Windows Compatible' suffix.
    • This includes specific tweaks to ensure the font works on Windows, in particular monospace identification and font name length limitations
  • If you are limited to monospaced fonts (because of your terminal, etc) then pick a font with the 'Mono' suffix.
    • This denotes that the Nerd Font glyphs will be monospaced not necessarily that the entire font will be monospaced

Ligatures

By the Nerd Font policy, the variant with the 'Mono' suffix is not supposed to have any ligatures. Use the non-Mono variants to have ligatures.

Explanation

Once you narrow down your font choice of family (Droid Sans, Inconsolata, etc) and style (bold, italic, etc) you have 2 main choices:

Option 1: Download already patched font

• download an already patched font from the complete folder
  • This is most likely the one you want. It includes all of the glyphs from all of the glyph sets. Only caution here is that some fonts have glyphs in the same code point so to include everything some had to be moved to alternate code points.

Option 2: Patch your own font

• patch your own variations with the various options provided by the font patcher (see each font's readme for full list of combinations available)
  • This is the option you want if the font you use is not already included or you want maximum control of what's included
  • This contains a list of all permutations of the various glyphs. E.g. You want the font with only Octicons or you want the font with just Font Awesome and Devicons. The goal is to provide every combination possible in this folder.

For more information see: The FAQ

Variations (Combinations)

The combinations and total number of combinations are provided here for reference if you want to create your own variation of a patched Nerd Font.

Why aren't all variations included ?

Combinations are no longer included by default because of the large inflation in size it caused the Repository and the amount of time it takes to rebuild all of the combinations. This issue would exponentially get worse as the numbers of Fonts and Glyph Sets provided increase.
