Martian Mono is a monospaced version of the Martian Grotesk font for code style design. It inherits Grotesk’s brutal and eye-catching aesthetics as well as all of its benefits—metrics equilibrium, readability and intelligibility, and convenience for web developers and designers who believe in a systematic approach to design.

The typeface features a tall x-height, and it has vertical metrics which guarantee equal space is present above the cap height and under the baseline. The latter makes this typeface an on-screen workhorse: it is evenly placed on buttons, inputs, lists, and forms. When coupled together, all the above features make Martian Mono a reasonable choice for any user interface design.
When choosing a font format, prefer ttf for variable and otf for static on macOS, and ttf for Windows.

| sWd | Semi Wide | 112.5% | semi-expanded |
| Std | Standard | 100% | normal |

| Cn | Condensed | 75% | condensed |
And 7 weights:

Originally designed for the screen, the glyph heights stick to the pixel grid on commonly used font sizes. In addition, it comes equipped with OpenType and TrueType hinting, and Martian Mono appears legible on most platforms, even when being rendered in small sizes.
For the best results, use the following pairs of size / line height:
- 7.5 / 10 (or 14, 18, etc.) px
- 10 / 12 (or 16, 20, etc.) px
- 12.5 / 14 (or 18, 22, etc.) px
- 15 / 20 (or 24, 28, etc.) px

For better compatibility with various terminal emulators and text editors on the desktop, it is a good idea to install the font not as a single variable font but as several different fonts. See the releases page, and download otf for macOS and ttf for Windows. Install the fonts.
Next, if your application has a font picker, just choose Martian Mono and the variant you require.
If the configuration is done using a text file, use Martian Mono for the default font variant (Martian Mono Std Rg), or try specifying the font name like MartianMono-NrRg for the Nr Rg variant.
When choosing a font variant for a darker (or pitch black) background for your terminal or text editor, consider choosing a "lighter" variant if the font looks "too bold" to you. White font on a dark background can have that effect, see here for details.
For example, go for Std Lt instead of Std Rg.
Once you install the font and start using it, you might notice that the picture might look quite confined:
Instead, you might want to opt for something more readable and easy for the eyes if you like:
The difference is line spacing. Learn how to set it up below, and consult the Font size and legibility chapter to learn about the best setting. Or, experiment yourself by setting different percentages (120%, 140%) or paddings in pixels (1, 2, 4, and so on).
Preferences → Profiles → (choose a profile) → Text → Font → [Change]. You will be met with a font picker dialog that has the Line Spacing property.
Preferences → Profiles → (choose a profile) → Text. Look for the n/n symbol that looks like a fraction. That's your line spacing, in percentage (100% is the default).
Open the config file (~/.config/kitty/kitty.conf). Look for the adjust_line_height property and see the documentation.
For setting line spacing in GUI versions of vim, see linespace/lsp.
Open your preferences. Add the line_padding_top and line_padding_bottom parameters. Both set the padding for a line of text in pixels.
