Roboto Mono vs JetBrains Mono
The Roboto Mono vs JetBrains Mono comparison pits a neutral, familiar monospace against a coding-specialized one. Both are free and legible, but JetBrains Mono targets developers with ligatures and a taller x-height, while Roboto Mono offers understated consistency for code, UI, and data alike.
What is Roboto Mono?
Roboto Mono was designed by Christian Robertson as the monospaced member of Google’s Roboto family. It carries the same clean, neutral, slightly grotesque-with-humanist character as Roboto, mapped onto a fixed-width grid. Roboto Mono is highly readable and pairs naturally with Roboto in interfaces, but it has no programming ligatures by default, rendering operators literally. It is free under the Apache License 2.0, making it easy to deploy anywhere Roboto already appears.
What is JetBrains Mono?
JetBrains Mono was created by JetBrains and released in 2020 as the default font for its IDEs. It is engineered specifically for reading code, featuring a notably tall x-height, increased character height, and balanced spacing that reduces eye strain during long sessions. It includes programming ligatures that fuse multi-character operators into single glyphs and disambiguates confusable characters such as 0/O and 1/l/I. It is free under the SIL OFL / Apache license. Both fonts appear in our developer-oriented best Google Fonts selection.
What’s the difference between Roboto Mono and JetBrains Mono?
Both are free monospace fonts, but they differ in ligature support, x-height, and intended use.
| Property | Roboto Mono | JetBrains Mono |
|---|---|---|
| Classification | Monospace (Roboto family) | Monospace coding font |
| Designer / year | Christian Robertson (Google) | JetBrains, 2020 |
| Key trait | Neutral, no ligatures by default | Tall x-height, coding ligatures |
| Best used for | UI, data, general code, Roboto pairing | IDEs, long coding sessions |
| Availability / license | Free, Apache License 2.0 | Free, SIL OFL / Apache |
When should you use each?
Use Roboto Mono when you want a calm, neutral monospace that blends with a Roboto-based interface, or for code snippets, tables, and data where literal character rendering and a familiar look matter more than coding features. Use JetBrains Mono when coding is the primary task and you want the readability boost of a taller x-height plus optional ligatures. In a terminal or IDE that supports ligatures, JetBrains Mono can make operator-heavy code feel cleaner; in a plain text context, Roboto Mono’s simplicity is an asset.
Which is better for coding?
For dedicated coding, JetBrains Mono is generally the stronger choice. Its taller x-height makes characters appear larger and clearer at the same size, and its ligatures and explicit 0/O and 1/l/I disambiguation are tailored to source code. Roboto Mono is perfectly usable for code but is a general-purpose mono without coding-specific tuning. If you want the most code-optimized experience, JetBrains Mono wins; if you want consistency with a Roboto design system, Roboto Mono fits better.

Are Roboto Mono and JetBrains Mono free?
Yes. Roboto Mono is free under the Apache License 2.0, and JetBrains Mono is free under the SIL Open Font License (with Apache terms historically referenced). Both can be used in personal and commercial projects, embedded, and self-hosted at no cost. For details on these licenses, see our font licensing guide.
Frequently Asked Questions
Does Roboto Mono have ligatures?
No, Roboto Mono does not include programming ligatures by default. It renders every operator and symbol literally. If you specifically want ligatures that combine sequences like => or != into single glyphs, JetBrains Mono is the better option, since ligatures are part of its coding-focused design.
Which font is better for a terminal?
Both work well in terminals. JetBrains Mono’s taller x-height can improve legibility for dense output, and its ligatures appear if your terminal supports them. Roboto Mono offers a cleaner, more neutral look without ligatures, which some users prefer for predictable, literal rendering of every character in command-line work.
Can I pair Roboto Mono with Roboto?
Yes, and that is one of its main advantages. Roboto Mono was designed as the monospaced sibling of Roboto, so it shares the same proportions and tone. Pairing them gives interfaces a cohesive look, using Roboto for prose and Roboto Mono for code blocks, data, or technical labels.
Which has a taller x-height?
JetBrains Mono has the taller x-height. Its designers raised the lowercase letters specifically to make code easier to read in IDEs, so characters look larger at a given point size. Roboto Mono’s x-height is more moderate, consistent with the rest of the Roboto family’s balanced proportions.
Are there other coding fonts worth comparing?
Yes. Fira Code, Source Code Pro, and Consolas are all popular monospace options with different approaches to ligatures and letterforms. If you are weighing system fonts instead of open-source ones, our Consolas vs Courier comparison covers the built-in monospace faces on Windows.
