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`](/docs/app/api-reference/components/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](https://web.dev/articles/cls).

You can also conveniently use all [Google Fonts](https://fonts.google.com/). 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.**

<AppOnly>

```tsx filename="app/layout.tsx" switcher
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>
  )
}
```

```jsx filename="app/layout.js" switcher
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](/docs/pages/building-your-application/routing/custom-app) under `/pages` as shown below:

```jsx filename="pages/_app.js"
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>
  )
}
```

### `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`](https://fonts.google.com/knowledge/glossary/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](https://fonts.google.com/variablefonts) font
- An array of weight values if the font is not a [variable google font](https://fonts.google.com/variablefonts). 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](https://fonts.google.com/variablefonts)

Examples:

- `weight: '400'`: A string for a single weight value - for the font [`Inter`](https://fonts.google.com/specimen/Inter?query=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`](https://developer.mozilla.org/docs/Web/CSS/font-style) with the following possibilities:

- A string [value](https://developer.mozilla.org/docs/Web/CSS/font-style#values) with default value of `'normal'`
- An array of style values if the font is not a [variable google font](https://fonts.google.com/variablefonts). 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](https://developer.mozilla.org/docs/Web/CSS/font-style)
- `style: ['italic','normal']`: An array of 2 values for `next/font/google` - the values are from `normal` and `italic`

### `subsets`

The font [`subsets`](https://fonts.google.com/knowledge/glossary/subsetting) defined by an array of string values with the names of each subset you would like to be [preloaded](/docs/app/api-reference/components/font#specifying-a-subset). Fonts specified via `subsets` will have a link preload tag injected into the head when the [`preload`](#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](https://fonts.google.com/variablefonts?vfquery=inter#font-families). You can find the possible `axes` values for your font by using the filter on the [Google variable fonts page](https://fonts.google.com/variablefonts#font-families) and looking for axes other than `wght`

### `display`

The font [`display`](https://developer.mozilla.org/docs/Web/CSS/@font-face/font-display) with possible string [values](https://developer.mozilla.org/docs/Web/CSS/@font-face/font-display#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](/docs/app/api-reference/components/font#preloading) 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](https://web.dev/cls/). 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](https://web.dev/cls/). 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](#css-variables).

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](https://developer.mozilla.org/docs/Web/CSS/@font-face#descriptors) 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](https://fonts.google.com/variablefonts) for the best performance and flexibility.

<AppOnly>

```tsx filename="app/layout.tsx" switcher
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>
  )
}
```

```jsx filename="app/layout.js" switcher
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**:

```tsx filename="app/layout.tsx" switcher
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>
  )
}
```

```jsx filename="app/layout.js" switcher
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](/docs/pages/building-your-application/routing/custom-app) under `/pages` as shown below:

```jsx filename="pages/_app.js"
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**:

```jsx filename="pages/_app.js"
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:

```jsx filename="app/layout.js"
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`.

<PagesOnly>

### Apply the font in `<head>`

You can also use the font without a wrapper and `className` by injecting it inside the `<head>` as follows:

```jsx filename="pages/_app.js"
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:

```jsx filename="pages/index.js"
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](https://fonts.google.com/knowledge/glossary/subsetting). 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`](/docs/app/api-reference/components/font#preload) is `true` will result in a warning.

This can be done by adding it to the function call:

<AppOnly>

```tsx filename="app/layout.tsx" switcher
const inter = Inter({ subsets: ['latin'] })
```

```jsx filename="app/layout.js" switcher
const inter = Inter({ subsets: ['latin'] })
```

</AppOnly>

<PagesOnly>

```jsx filename="pages/_app.js"
const inter = Inter({ subsets: ['latin'] })
```

</PagesOnly>

View the [Font API Reference](/docs/app/api-reference/components/font) 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:

```ts filename="app/fonts.ts" switcher
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',
})
```

```js filename="app/fonts.js" switcher
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',
})
```

<AppOnly>

```tsx filename="app/layout.tsx" switcher
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>
  )
}
```

```jsx filename="app/layout.js" switcher
import { inter } from './fonts'

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

```tsx filename="app/page.tsx" switcher
import { roboto_mono } from './fonts'

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

```jsx filename="app/page.js" switcher
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](/docs/app/api-reference/components/font#variable) and use it with your preferred CSS solution:

<AppOnly>

```tsx filename="app/layout.tsx" switcher
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>
  )
}
```

```jsx filename="app/layout.js" switcher
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>

```css filename="app/global.css"
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](https://fonts.google.com/variablefonts) for the best performance and flexibility.

<AppOnly>

```tsx filename="app/layout.tsx" switcher
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>
  )
}
```

```jsx filename="app/layout.js" switcher
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>

```jsx filename="pages/_app.js"
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:

```js
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](/docs/app/api-reference/components/font) for more information.

### With Tailwind CSS

`next/font` integrates seamlessly with [Tailwind CSS](https://tailwindcss.com/) using [CSS variables](/docs/app/api-reference/components/font#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.

<AppOnly>

```tsx filename="app/layout.tsx" switcher
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>
  )
}
```

```jsx filename="app/layout.js" switcher
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>
  )
}
```

```jsx filename="pages/_app.js"
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](/docs/app/guides/tailwind-css#configuring-tailwind):

### Tailwind CSS v4

As of [Tailwind v4](https://tailwindcss.com/blog/tailwindcss-v4), there is zero configuration required by default. If you do need to configure Tailwind, you can follow the [official documentation](https://tailwindcss.com/blog/tailwindcss-v4#css-first-configuration) for configuring the global CSS file.

```css filename="global.css"
@import 'tailwindcss';

@theme inline {
  --font-sans: var(--font-inter);
  --font-mono: var(--font-roboto-mono);
}
```

### Tailwind CSS v3

```js filename="tailwind.config.js"
/** @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.

```html
<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`](#classname)
- [`style`](#style-1)
- [CSS Variables](#css-variables)

#### `className`

Returns a read-only CSS `className` for the loaded font to be passed to an HTML element.

```tsx
<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.

```tsx
<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:

```tsx filename="app/page.tsx" switcher
import { Inter } from 'next/font/google'
import styles from '../styles/component.module.css'

const inter = Inter({
  variable: '--font-inter',
})
```

```jsx filename="app/page.js" switcher
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.

```tsx filename="app/page.tsx" switcher
<main className={inter.variable}>
  <p className={styles.text}>Hello World</p>
</main>
```

```jsx filename="app/page.js" switcher
<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:

```css filename="styles/component.module.css"
.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:

```ts filename="styles/fonts.ts" switcher
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 }
```

```js filename="styles/fonts.js" switcher
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:

```tsx filename="app/page.tsx" switcher
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>
  )
}
```

```jsx filename="app/page.js" switcher
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:

```json filename="tsconfig.json"
{
  "compilerOptions": {
    "paths": {
      "@/fonts": ["./styles/fonts"]
    }
  }
}
```

You can now import any font definition as follows:

```tsx filename="app/about/page.tsx" switcher
import { greatVibes, sourceCodePro400 } from '@/fonts'
```

```jsx filename="app/about/page.js" switcher
import { greatVibes, sourceCodePro400 } from '@/fonts'
```

### Preloading

<AppOnly>

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](/docs/app/api-reference/file-conventions/page), it is preloaded on the unique route for that page.
- If it's a [layout](/docs/app/api-reference/file-conventions/layout), it is preloaded on all the routes wrapped by the layout.
- If it's the [root layout](/docs/app/api-reference/file-conventions/layout#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](/docs/pages/building-your-application/routing/pages-and-layouts), it is preloaded on the unique route for that page
- if it's in the [custom App](/docs/pages/building-your-application/routing/custom-app), it is preloaded on all the routes of the site under `/pages`
