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.

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:

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

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.

OpenType features

Starting from v2.304, JetBrains Mono has added support for alternate characters. Stylistic Sets ss01-20 usually change a group of characters. Character Variant cv01-99 usually changes only one character. Here are the instructions for enabling these features.

Basic Character Set
