## About Oxygen Mono

Oxygen Mono is a monospaced sans serif in which every character occupies the same width. Vernon Adams drew it as the companion to Oxygen, the typeface made for the KDE project's user interface and branding, so the two can share a desktop. The specimen shows the details that matter in code: the zero carries a slash, the lowercase l ends in a curved tail, and the i stands on a slab-like foot that fills its cell and sets it apart from the numeral 1. The lowercase is tall, which keeps lines even. The family has one Regular style of 362 glyphs across the Latin and Latin Extended subsets and is not a variable font. Oxygen Mono is published under the SIL Open Font License 1.1.

## Where it works

- **Code editors and terminals**: Fixed widths align indentation, while the slashed zero and tailed l separate 0 from O and l from 1.
- **Desktop interfaces alongside Oxygen**: It was made as the monospace partner of the KDE interface face, for consoles and logs inside the same environment.
- **Code samples in documentation**: One upright style is enough for inline snippets and command lines inside a page set in a proportional face.
- **Columns of figures**: Equal character widths line numbers up in plain-text tables, receipts and log output.

## Things to know

- **Regular only**: Oxygen Mono has no bold and no italic, so syntax highlighting has to rely on colour.
- **Latin and Latin Extended**: The 362 glyphs cover the two Latin subsets; no other scripts are included.
- **Reserved name**: The license notice reserves the font name Oxygen, so a modified version needs a different name.
