title: Font Module nav_title: Font description: Optimizing loading web fonts with the built-in `next/font` loaders.

{/* The content of this doc is shared between the app and pages router. You can use the <PagesOnly>Content</PagesOnly> component to add content that is specific to the Pages Router. Any shared content should not be wrapped in a component. */}

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.

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'],
  display: 'swap',
})

export default function RootLayout({
  children,
}: {
  children: React.ReactNode
}) {
  return (
    <html lang="en" className={inter.className}>
      <body>{children}</body>
    </html>
  )
}

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'],
  display: 'swap',
})

export default function RootLayout({ children }) {
  return (
    <html lang="en" className={inter.className}>
      <body>{children}</body>
    </html>
  )
}

</AppOnly> <PagesOnly>

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>
  )
}

</PagesOnly>

`src`

The path of the font file as a string or an array of objects (with type Array<{path: string, weight?: string, style?: string}>) relative to the directory where the font loader function is called.

Used in next/font/local

Required

Examples:

src:'./fonts/my-font.woff2' where my-font.woff2 is placed in a directory named fonts inside the app directory
src:[{path: './inter/Inter-Thin.ttf', weight: '100',},{path: './inter/Inter-Regular.ttf',weight: '400',},{path: './inter/Inter-Bold-Italic.ttf', weight: '700',style: 'italic',},]
if the font loader function is called in app/page.tsx using src:'../styles/fonts/my-font.ttf', then my-font.ttf is placed in styles/fonts at the root of the project

`weight`

The font weight with the following possibilities:

A string with possible values of the weights available for the specific font or a range of values if it's a variable font
An array of weight values if the font is not a variable google font. It applies to next/font/google only.

Used in next/font/google and next/font/local

Required if the font being used is not variable

Examples:

weight: '400': A string for a single weight value - for the font Inter, the possible values are '100', '200', '300', '400', '500', '600', '700', '800', '900' or 'variable' where 'variable' is the default)
weight: '100 900': A string for the range between 100 and 900 for a variable font
weight: ['100','400','900']: An array of 3 possible values for a non variable font

`style`

The font style with the following possibilities:

A string value with default value of 'normal'
An array of style values if the font is not a variable google font. It applies to next/font/google only.

Used in next/font/google and next/font/local

Optional

Examples:

style: 'italic': A string - it can be normal or italic for next/font/google
style: 'oblique': A string - it can take any value for next/font/local but is expected to come from standard font styles
style: ['italic','normal']: An array of 2 values for next/font/google - the values are from normal and italic

`subsets`

The font subsets defined by an array of string values with the names of each subset you would like to be preloaded. Fonts specified via subsets will have a link preload tag injected into the head when the preload option is true, which is the default.

Used in next/font/google

Optional

Examples:

subsets: ['latin']: An array with the subset latin

You can find a list of all subsets on the Google Fonts page for your font.

`axes`

Some variable fonts have extra axes that can be included. By default, only the font weight is included to keep the file size down. The possible values of axes depend on the specific font.

Used in next/font/google

Optional

Examples:

axes: ['slnt']: An array with value slnt for the Inter variable font which has slnt as additional axes as shown here. You can find the possible axes values for your font by using the filter on the Google variable fonts page and looking for axes other than wght

`display`

The font display with possible string values of 'auto', 'block', 'swap', 'fallback' or 'optional' with default value of 'swap'.

Used in next/font/google and next/font/local

Optional

Examples:

display: 'optional': A string assigned to the optional value

`preload`

A boolean value that specifies whether the font should be preloaded or not. The default is true.

Used in next/font/google and next/font/local

Optional

Examples:

preload: false

`fallback`

The fallback font to use if the font cannot be loaded. An array of strings of fallback fonts with no default.

Optional

Used in next/font/google and next/font/local

Examples:

fallback: ['system-ui', 'arial']: An array setting the fallback fonts to system-ui or arial

`adjustFontFallback`

For next/font/google: A boolean value that sets whether an automatic fallback font should be used to reduce Cumulative Layout Shift. The default is true.
For next/font/local: A string or boolean false value that sets whether an automatic fallback font should be used to reduce Cumulative Layout Shift. The possible values are 'Arial', 'Times New Roman' or false. The default is 'Arial'.

Used in next/font/google and next/font/local

Optional

Examples:

adjustFontFallback: false: for next/font/google
adjustFontFallback: 'Times New Roman': for next/font/local

`variable`

A string value to define the CSS variable name to be used if the style is applied with the CSS variable method.

Used in next/font/google and next/font/local

Optional

Examples:

variable: '--my-font': The CSS variable --my-font is declared

`declarations`

An array of font face descriptor key-value pairs that define the generated @font-face further.

Used in next/font/local

Optional

Examples:

declarations: [{ prop: 'ascent-override', value: '90%' }]

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.

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'],
  display: 'swap',
})

export default function RootLayout({
  children,
}: {
  children: React.ReactNode
}) {
  return (
    <html lang="en" className={inter.className}>
      <body>{children}</body>
    </html>
  )
}

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'],
  display: 'swap',
})

export default function RootLayout({ children }) {
  return (
    <html lang="en" className={inter.className}>
      <body>{children}</body>
    </html>
  )
}

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'],
  display: 'swap',
})

export default function RootLayout({
  children,
}: {
  children: React.ReactNode
}) {
  return (
    <html lang="en" className={roboto.className}>
      <body>{children}</body>
    </html>
  )
}

import { Roboto } from 'next/font/google'

const roboto = Roboto({
  weight: '400',
  subsets: ['latin'],
  display: 'swap',
})

export default function RootLayout({ children }) {
  return (
    <html lang="en" className={roboto.className}>
      <body>{children}</body>
    </html>
  )
}

</AppOnly> <PagesOnly>

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>
  )
}

</PagesOnly>

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 as Roboto_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>
  )
}

</PagesOnly>

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'] })

const inter = Inter({ subsets: ['latin'] })

</AppOnly> <PagesOnly>

const inter = Inter({ subsets: ['latin'] })

</PagesOnly>

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',
})

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',
})

import { inter } from './fonts'

export default function Layout({ children }: { children: React.ReactNode }) {
  return (
    <html lang="en" className={inter.className}>
      <body>
        <div>{children}</div>
      </body>
    </html>
  )
}

import { inter } from './fonts'

export default function Layout({ children }) {
  return (
    <html lang="en" className={inter.className}>
      <body>
        <div>{children}</div>
      </body>
    </html>
  )
}

import { roboto_mono } from './fonts'

export default function Page() {
  return (
    <>
      <h1 className={roboto_mono.className}>My page</h1>
    </>
  )
}

import { roboto_mono } from './fonts'

export default function Page() {
  return (
    <>
      <h1 className={roboto_mono.className}>My page</h1>
    </>
  )
}

</AppOnly>

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:

import { Inter, Roboto_Mono } from 'next/font/google'
import styles from './global.css'

const inter = Inter({
  subsets: ['latin'],
  variable: '--font-inter',
  display: 'swap',
})

const roboto_mono = Roboto_Mono({
  subsets: ['latin'],
  variable: '--font-roboto-mono',
  display: 'swap',
})

export default function RootLayout({
  children,
}: {
  children: React.ReactNode
}) {
  return (
    <html lang="en" className={`${inter.variable} ${roboto_mono.variable}`}>
      <body>
        <h1>My App</h1>
        <div>{children}</div>
      </body>
    </html>
  )
}

import { Inter, Roboto_Mono } from 'next/font/google'

const inter = Inter({
  subsets: ['latin'],
  variable: '--font-inter',
  display: 'swap',
})

const roboto_mono = Roboto_Mono({
  subsets: ['latin'],
  variable: '--font-roboto-mono',
  display: 'swap',
})

export default function RootLayout({ children }) {
  return (
    <html lang="en" className={`${inter.variable} ${roboto_mono.variable}`}>
      <body>
        <h1>My App</h1>
        <div>{children}</div>
      </body>
    </html>
  )
}

</AppOnly>

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 `app`
const myFont = localFont({
  src: './my-font.woff2',
  display: 'swap',
})

export default function RootLayout({
  children,
}: {
  children: React.ReactNode
}) {
  return (
    <html lang="en" className={myFont.className}>
      <body>{children}</body>
    </html>
  )
}

import localFont from 'next/font/local'

// Font files can be colocated inside of `app`
const myFont = localFont({
  src: './my-font.woff2',
  display: 'swap',
})

export default function RootLayout({ children }) {
  return (
    <html lang="en" className={myFont.className}>
      <body>{children}</body>
    </html>
  )
}

</AppOnly> <PagesOnly>

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>
  )
}

</PagesOnly>

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, Roboto_Mono } from 'next/font/google'

const inter = Inter({
  subsets: ['latin'],
  display: 'swap',
  variable: '--font-inter',
})

const roboto_mono = Roboto_Mono({
  subsets: ['latin'],
  display: 'swap',
  variable: '--font-roboto-mono',
})

export default function RootLayout({
  children,
}: {
  children: React.ReactNode
}) {
  return (
    <html
      lang="en"
      className={`${inter.variable} ${roboto_mono.variable} antialiased`}
    >
      <body>{children}</body>
    </html>
  )
}

import { Inter, Roboto_Mono } from 'next/font/google'

const inter = Inter({
  subsets: ['latin'],
  display: 'swap',
  variable: '--font-inter',
})

const roboto_mono = Roboto_Mono({
  subsets: ['latin'],
  display: 'swap',
  variable: '--font-roboto-mono',
})

export default function RootLayout({ children }) {
  return (
    <html
      lang="en"
      className={`${inter.variable} ${roboto_mono.variable} antialiased`}
    >
      <body>{children}</body>
    </html>
  )
}

</AppOnly> <PagesOnly>

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>
  )
}

</PagesOnly>

Finally, add the CSS variable to your Tailwind CSS config:

@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
style
CSS Variables

`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',
})

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>

<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 }

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>
  )
}

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'

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 routes 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 a layout, it is preloaded on all the routes wrapped by the layout.
If it's the root layout, it is preloaded on all routes.

</AppOnly> <PagesOnly>

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

</PagesOnly>
