Set a custom font for your entire site or separately for headings and body text. Use Google Fonts, local font files, or externally hosted fonts. The default font varies by theme.
Fonts are controlled by the [fonts property](/organize/settings#param-fonts) in your `docs.json`.
## Google Fonts
Mintlify automatically loads [Google Fonts](https://fonts.google.com) when you specify a font family name in your `docs.json`.
```json docs.json
"fonts": {
"family": "Inter"
}
```
## Local fonts
To use local fonts, place your font files in your project directory and reference them in your `docs.json` configuration.
### Setting up local fonts
<Steps>
<Step title="Add font files to your project">
For example, create a `fonts` directory and add your font files:
```text
your-project/
├── fonts/
│ ├── InterDisplay-Regular.woff2
│ └── InterDisplay-Bold.woff2
├── docs.json
└── ...
```
</Step>
<Step title="Configure fonts in docs.json">
Reference your local fonts using relative paths from your project root:
```json docs.json
{
"fonts": {
"family": "InterDisplay",
"source": "/fonts/InterDisplay-Regular.woff2",
"format": "woff2",
"weight": 400
}
}
```
</Step>
</Steps>
### Local fonts for headings and body
Configure separate local fonts for headings and body text in your `docs.json`:
```json docs.json
{
"fonts": {
"heading": {
"family": "InterDisplay",
"source": "/fonts/InterDisplay-Bold.woff2",
"format": "woff2",
"weight": 700
},
"body": {
"family": "InterDisplay",
"source": "/fonts/InterDisplay-Regular.woff2",
"format": "woff2",
"weight": 400
}
}
}
```
## Externally hosted fonts
Use externally hosted fonts by referencing a font source URL in your `docs.json`:
```json docs.json
{
"fonts": {
"family": "Hubot Sans",
"source": "https://mintlify-assets.b-cdn.net/fonts/Hubot-Sans.woff2",
"format": "woff2",
"weight": 400
}
}
```
