The CSS and web font files to easily self-host the “Cascadia Code” font. Please visit the main Fontsource monorepo to view more details on this package.


Fontsource assumes you are using a bundler, such as Webpack, to load in CSS. Solutions like CRA, Gatsby and Next.js are prebuilt examples that are compatible.

yarn add @fontsource/cascadia-code // npm install @fontsource/cascadia-code

Then within your app entry file or site component, import it in. For example in Gatsby, you could choose to import it into a layout template (layout.js), page component (index.js), or gatsby-browser.js.

import "@fontsource/cascadia-code" // Defaults to weight 400.

Fontsource allows you to select weights and even individual styles, allowing you to cut down on payload sizes to the last byte! Utilizing the CSS unicode-range selector, all language subsets are accounted for.

import "@fontsource/cascadia-code/500.css" // Weight 500.
import "@fontsource/cascadia-code/900-italic.css" // Italic variant.

Alternatively, the same solutions could be imported via SCSS!

@import "~@fontsource/cascadia-code/index.css"; // Weight 400.
@import "~@fontsource/cascadia-code/300-italic.css";

For more advanced setups, you can use our highly customisable Sass mixins that can modify many of the existing @font-face variables.

@import "~@fontsource/cascadia-code/scss/mixins";

// Fully customisable single @font-face mixin.
@include fontFaceCustom(
  $weight: 600,
  $display: optional,
  $unicodeRange: false
// More options available in link below.

You can see all of the existing inputtable mixin variables here.

These examples may not reflect actual compatibility. Please refer below.

Supported variables:

  • Weights: [400]
  • Styles: [normal]

Finally, you can reference the font name in a CSS stylesheet, CSS Module, or CSS-in-JS.

body {
  font-family: "Cascadia Code";

Additional Options

In the rare case you need to individually select a language subset and not utilize the CSS unicode-range selector, you may specify the import as follows. This is especially not recommended for languages, such as Japanese, with a large amount of characters.

import "@fontsource/cascadia-code/latin-ext.css" // All weights with normal style included.
import "@fontsource/cascadia-code/cyrillic-ext-500.css" // Weight 500 with normal style.
import "@fontsource/cascadia-code/greek-900-italic.css" // Italic variant.
  • Supported subsets: [latin-ext,pl-latin-ext]


It is important to always read the license for every font that you use. Most of the fonts in the collection use the SIL Open Font License, v1.1. Some fonts use the Apache 2 license. The Ubuntu fonts use the Ubuntu Font License v1.0.
