# Library

The library has a page for each member, comparisons with other typefaces, guides and explainers. It also has a page for every script and every language on the map.

## Members

- [Katagami Sans](https://katagami.kevinliu.studio/katagami-sans): Katagami Sans is the core member of the family. It is a sans serif for interfaces and display with squared bowls, level cuts and square punctuation.
- [Katagami Round](https://katagami.kevinliu.studio/katagami-round): Katagami Round squares its bowls less than Katagami Sans and rounds every sharp vertex. It is for interfaces and text that should look softer.
- [Katagami Text](https://katagami.kevinliu.studio/katagami-text): Katagami Text is the member for reading. It has a lower x-height, is set smaller and tighter, and has wider round letters and capitals.
- [Katagami Serif](https://katagami.kevinliu.studio/katagami-serif): Katagami Serif is Katagami Text with rectangular serifs. Each serif ends square and meets the stroke in a short bracket.
- [Katagami Mono](https://katagami.kevinliu.studio/katagami-mono): Katagami Mono is Katagami Sans fitted to a monospace cell. It is for code, terminals and tables.

Katagami draws its own Latin, Greek and Cyrillic. It merges 19 scripts from the Noto Sans fonts and scales them to Katagami's x-height.

## Guides

- [Monospace fonts for code](https://katagami.kevinliu.studio/fonts-for/coding): A monospace font for code needs one width for every character, distinct look-alike characters and ligatures you can turn off. Katagami Mono, JetBrains Mono, Fira Code, IBM Plex Mono, Geist Mono and Berkeley Mono are compared on license, weights, axes and features.
- [Fonts for interfaces](https://katagami.kevinliu.studio/fonts-for/interfaces): An interface font needs tabular figures, distinct look-alike characters, enough weights, coverage for your languages and a license for embedding. Katagami Sans and Round are compared with Inter, Geist, Roboto, SF Pro and IBM Plex Sans.
- [Fonts for long reading](https://katagami.kevinliu.studio/fonts-for/reading): Long text needs a moderate x-height, spacing set for body sizes and bold weights that stay open. Katagami Text and Katagami Serif are free typefaces for articles, documentation and books.
- [Fonts for many languages](https://katagami.kevinliu.studio/fonts-for/many-languages): Katagami sets the main language of places where 99.9 percent of people live. It draws Latin, Greek and Cyrillic, merges 19 more scripts and sets Chinese, Japanese and Korean with companion fonts.
- [Commercial use](https://katagami.kevinliu.studio/free-for-commercial-use): Katagami is free for commercial use under the SIL Open Font License 1.1. The license allows use in apps, websites and print, and it asks you to keep the license with the files and to rename changed versions.

## Explainers

- [Variable fonts](https://katagami.kevinliu.studio/learn/variable-fonts): A variable font holds a whole range of a design in one file. Katagami's weight axis runs from 100 to 900, its files name their styles, and CSS can set any weight in between.
- [OpenType features](https://katagami.kevinliu.studio/learn/opentype-features): OpenType features are substitutions that a font carries and a browser applies on request. CSS turns them on with font-variant and font-feature-settings, and Katagami Sans has 41 features you can switch.
- [Squared curves](https://katagami.kevinliu.studio/learn/squared-curves): How far a curve's handles reach toward its corner decides how square a bowl looks. A table gives the handle fraction f for a circle and for Katagami Text, Round and Sans.
- [Katagami stencils](https://katagami.kevinliu.studio/learn/katagami-stencils): Katagami are Japanese paper stencils for dyeing cloth, and the word 型紙 means pattern paper. They are cut by hand in Suzuka with four cutting methods.
- [Fonts in coding agents](https://katagami.kevinliu.studio/learn/fonts-in-coding-agents): Coding agents print their interface as text in a terminal grid. The font has to draw their box-drawing, block, Braille and status characters at one cell width, and each terminal has its own setting for Katagami Mono.
- [Agent-native fonts](https://katagami.kevinliu.studio/learn/agent-native-fonts): An agent needs readable text, an index, a license it can act on, stable addresses and facts as data before it can use a font. Katagami publishes each of these and offers a prompt for a coding agent.

## Scripts

The [scripts page](https://katagami.kevinliu.studio/scripts) lists every script in Katagami and whether it is drawn, merged or set by a companion font.

## Languages

The [languages page](https://katagami.kevinliu.studio/languages) lists every language on the map, and each of the 234 languages has its own page.

## Machine-readable text

Every page has a Markdown twin at the same address with `.md`. The file [llms.txt](https://katagami.kevinliu.studio/llms.txt) lists every page, and [llms-full.txt](https://katagami.kevinliu.studio/llms-full.txt) holds every page except the language pages in one file.
