Font Module
next/font
automatically optimizes your fonts (including custom fonts) and removes external network requests for improved privacy and performance.
It includes built-in automatic self-hosting for any font file. This means you can optimally load web fonts with no layout shift.
You can also conveniently use all Google Fonts. CSS and font files are downloaded at build time and self-hosted with the rest of your static assets. No requests are sent to Google by the browser.
To use the font in all your pages, add it to _app.js
file under /pages
as shown below:
import { Inter } from 'next/font/google'
// If loading a variable font, you don't need to specify the font weight
const inter = Inter({ subsets: ['latin'] })
export default function MyApp({ Component, pageProps }) {
return (
<main className={inter.className}>
<Component {...pageProps} />
</main>
)
}

Examples
Google Fonts
To use a Google font, import it from next/font/google
as a function. We recommend using variable fonts for the best performance and flexibility.
To use the font in all your pages, add it to _app.js
file under /pages
as shown below:
import { Inter } from 'next/font/google'
// If loading a variable font, you don't need to specify the font weight
const inter = Inter({ subsets: ['latin'] })
export default function MyApp({ Component, pageProps }) {
return (
<main className={inter.className}>
<Component {...pageProps} />
</main>
)
}
If you can't use a variable font, you will need to specify a weight:
import { Roboto } from 'next/font/google'
const roboto = Roboto({
weight: '400',
subsets: ['latin'],
})
export default function MyApp({ Component, pageProps }) {
return (
<main className={roboto.className}>
<Component {...pageProps} />
</main>
)
}
You can specify multiple weights and/or styles by using an array:
const roboto = Roboto({
weight: ['400', '700'],
style: ['normal', 'italic'],
subsets: ['latin'],
display: 'swap',
})
Good to know: Use an underscore (_) for font names with multiple words. E.g.
Roboto Mono
should be imported asRoboto_Mono
.
Apply the font in <head>
You can also use the font without a wrapper and className
by injecting it inside the <head>
as follows:
import { Inter } from 'next/font/google'
const inter = Inter({ subsets: ['latin'] })
export default function MyApp({ Component, pageProps }) {
return (
<>
<style jsx global>{`
html {
font-family: ${inter.style.fontFamily};
}
`}</style>
<Component {...pageProps} />
</>
)
}
Single page usage
To use the font on a single page, add it to the specific page as shown below:
import { Inter } from 'next/font/google'
const inter = Inter({ subsets: ['latin'] })
export default function Home() {
return (
<div className={inter.className}>
<p>Hello World</p>
</div>
)
}
Specifying a subset
Google Fonts are automatically subset. This reduces the size of the font file and improves performance. You'll need to define which of these subsets you want to preload. Failing to specify any subsets while preload
is true
will result in a warning.
This can be done by adding it to the function call:
const inter = Inter({ subsets: ['latin'] })
View the Font API Reference for more information.
Using Multiple Fonts
You can import and use multiple fonts in your application. There are two approaches you can take.
The first approach is to create a utility function that exports a font, imports it, and applies its className
where needed. This ensures the font is preloaded only when it's rendered:
import { Inter, Roboto_Mono } from 'next/font/google'
export const inter = Inter({
subsets: ['latin'],
display: 'swap',
})
export const roboto_mono = Roboto_Mono({
subsets: ['latin'],
display: 'swap',
})
In the example above, Inter
will be applied globally, and Roboto Mono
can be imported and applied as needed.
Alternatively, you can create a CSS variable and use it with your preferred CSS solution:
html {
font-family: var(--font-inter);
}
h1 {
font-family: var(--font-roboto-mono);
}
In the example above, Inter
will be applied globally, and any <h1>
tags will be styled with Roboto Mono
.
Recommendation: Use multiple fonts conservatively since each new font is an additional resource the client has to download.
Local Fonts
Import next/font/local
and specify the src
of your local font file. We recommend using variable fonts for the best performance and flexibility.
import localFont from 'next/font/local'
// Font files can be colocated inside of `pages`
const myFont = localFont({ src: './my-font.woff2' })
export default function MyApp({ Component, pageProps }) {
return (
<main className={myFont.className}>
<Component {...pageProps} />
</main>
)
}
If you want to use multiple files for a single font family, src
can be an array:
const roboto = localFont({
src: [
{
path: './Roboto-Regular.woff2',
weight: '400',
style: 'normal',
},
{
path: './Roboto-Italic.woff2',
weight: '400',
style: 'italic',
},
{
path: './Roboto-Bold.woff2',
weight: '700',
style: 'normal',
},
{
path: './Roboto-BoldItalic.woff2',
weight: '700',
style: 'italic',
},
],
})
View the Font API Reference for more information.
With Tailwind CSS
next/font
integrates seamlessly with Tailwind CSS using CSS variables.
In the example below, we use the Inter
and Roboto_Mono
fonts from next/font/google
(you can use any Google Font or Local Font). Use the variable
option to define a CSS variable name, such as inter
and roboto_mono
for these fonts, respectively. Then, apply inter.variable
and roboto_mono.variable
to include the CSS variables in your HTML document.
Good to know: You can add these variables to the
<html>
or<body>
tag, depending on your preference, styling needs or project requirements.
import { Inter } from 'next/font/google'
const inter = Inter({
subsets: ['latin'],
variable: '--font-inter',
})
const roboto_mono = Roboto_Mono({
subsets: ['latin'],
display: 'swap',
variable: '--font-roboto-mono',
})
export default function MyApp({ Component, pageProps }) {
return (
<main className={`${inter.variable} ${roboto_mono.variable} font-sans`}>
<Component {...pageProps} />
</main>
)
}
Finally, add the CSS variable to your Tailwind CSS config:
Tailwind CSS v4
As of Tailwind v4, there is zero configuration required by default. If you do need to configure Tailwind, you can follow the official documentation for configuring the global CSS file.
@import "tailwindcss";
@theme inline {
--font-sans: var(--font-inter);
--font-mono: var(--font-roboto-mono);
}
Tailwind CSS v3
/** @type {import('tailwindcss').Config} */
module.exports = {
content: [
'./pages/**/*.{js,ts,jsx,tsx}',
'./components/**/*.{js,ts,jsx,tsx}',
'./app/**/*.{js,ts,jsx,tsx}',
],
theme: {
extend: {
fontFamily: {
sans: ['var(--font-inter)'],
mono: ['var(--font-roboto-mono)'],
},
},
},
plugins: [],
}
You can now use the font-sans
and font-mono
utility classes to apply the font to your elements.
<p class="font-sans ...">The quick brown fox ...</p>
<p class="font-mono ...">The quick brown fox ...</p>
Applying Styles
You can apply the font styles in three ways:
className
Returns a read-only CSS className
for the loaded font to be passed to an HTML element.
<p className={inter.className}>Hello, Next.js!</p>
style
Returns a read-only CSS style
object for the loaded font to be passed to an HTML element, including style.fontFamily
to access the font family name and fallback fonts.
<p style={inter.style}>Hello World</p>
CSS Variables
If you would like to set your styles in an external style sheet and specify additional options there, use the CSS variable method.
In addition to importing the font, also import the CSS file where the CSS variable is defined and set the variable option of the font loader object as follows:
import { Inter } from 'next/font/google'
import styles from '../styles/component.module.css'
const inter = Inter({
variable: '--font-inter',
})
To use the font, set the className
of the parent container of the text you would like to style to the font loader's variable
value and the className
of the text to the styles
property from the external CSS file.
<main className={inter.variable}>
<p className={styles.text}>Hello World</p>
</main>
Define the text
selector class in the component.module.css
CSS file as follows:
.text {
font-family: var(--font-inter);
font-weight: 200;
font-style: italic;
}
In the example above, the text Hello World
is styled using the Inter
font and the generated font fallback with font-weight: 200
and font-style: italic
.
Using a font definitions file
Every time you call the localFont
or Google font function, that font will be hosted as one instance in your application. Therefore, if you need to use the same font in multiple places, you should load it in one place and import the related font object where you need it. This is done using a font definitions file.
For example, create a fonts.ts
file in a styles
folder at the root of your app directory.
Then, specify your font definitions as follows:
import { Inter, Lora, Source_Sans_3 } from 'next/font/google'
import localFont from 'next/font/local'
// define your variable fonts
const inter = Inter()
const lora = Lora()
// define 2 weights of a non-variable font
const sourceCodePro400 = Source_Sans_3({ weight: '400' })
const sourceCodePro700 = Source_Sans_3({ weight: '700' })
// define a custom local font where GreatVibes-Regular.ttf is stored in the styles folder
const greatVibes = localFont({ src: './GreatVibes-Regular.ttf' })
export { inter, lora, sourceCodePro400, sourceCodePro700, greatVibes }
You can now use these definitions in your code as follows:
import { inter, lora, sourceCodePro700, greatVibes } from '../styles/fonts'
export default function Page() {
return (
<div>
<p className={inter.className}>Hello world using Inter font</p>
<p style={lora.style}>Hello world using Lora font</p>
<p className={sourceCodePro700.className}>
Hello world using Source_Sans_3 font with weight 700
</p>
<p className={greatVibes.className}>My title in Great Vibes font</p>
</div>
)
}
To make it easier to access the font definitions in your code, you can define a path alias in your tsconfig.json
or jsconfig.json
files as follows:
{
"compilerOptions": {
"paths": {
"@/fonts": ["./styles/fonts"]
}
}
}
You can now import any font definition as follows:
import { greatVibes, sourceCodePro400 } from '@/fonts'
Preloading
When a font function is called on a page of your site, it is not globally available and preloaded on all routes. Rather, the font is only preloaded on the related route/s based on the type of file where it is used:
- if it's a unique page, it is preloaded on the unique route for that page
- if it's in the custom App, it is preloaded on all the routes of the site under
/pages
