Nextjs Fonts: How to Enhance Text in Web Projects

Using fonts in Next.js : Google Fonts, Local and TailwindCSS

When it comes to web development, the choice of fonts plays a crucial role in both the aesthetics and usability of a web application. Next.js, a powerful React framework, offers developers streamlined ways to manage fonts, ensuring that their web projects are visually appealing and performant. In this comprehensive guide, we will dive deep into nextjs fonts, covering everything from basic integration to advanced optimization techniques.

Overview of Next.js fonts

Before we delve into the specifics of Next.js font management, let’s first understand the importance of fonts in web development and get acquainted with Next.js and its font-handling capabilities.

Understanding Next.js and Its Font Handling Capabilities

Next.js is a popular React framework, one key feature of Next.js is its efficient handling of fonts. Unlike traditional CSS methods, Next.js streamlines font management, allowing developers to leverage both system and custom fonts with ease. Understanding these capabilities is the first step in effectively utilizing fonts in your Next.js projects.

Types of Next.js Fonts

In the realm of Next.js, fonts can be broadly categorized into system fonts and custom fonts.

Let’s take a closer look at these two types:

System Fonts

System fonts are pre-installed fonts available on user’s devices. They offer faster load times and provide a native feel to your web application.

Examples of system fonts include Arial, Times New Roman, and Helvetica. Next.js makes it easy to incorporate system fonts into your project by simply specifying the font family in your CSS files.

For example:

body {
  font-family: Arial, sans-serif;
}

By using system fonts, you can ensure quick load times and a consistent user experience across different devices and browsers. However, it’s crucial to provide fallback font options to ensure maximum compatibility.

Custom Fonts

Custom fonts, on the other hand, are externally sourced and provide a unique look to your application. These fonts are not pre-installed on user’s devices and need to be loaded from external sources.

Examples of popular sources for custom fonts include Google Fonts and Adobe Fonts.

Integrating custom fonts in Next.js is relatively straightforward. You can either host the font files directly in your project or link to external sources.

Let’s take a look at an example of adding a Google Font to your Next.js application:

import Head from 'next/head';

export default function Home() {
  return (
    <div>
      <Head>
        <link href="https://fonts.googleapis.com/css2?family=Roboto:wght@400;700&display=swap" rel="stylesheet"/>
      </Head>
      {/ Rest of your component /}
    </div>
  );
}

When using custom fonts, it’s important to consider load times and potential render-blocking issues that may affect the performance of your web application.

Providing Fallback Font Options

While system fonts are widely available, it’s essential to provide fallback font options to ensure maximum compatibility across various devices and operating systems. Not all users will have the same system fonts installed on their devices, so it’s crucial to have backup options in case the desired system font is not available.

To provide fallback font options, you can specify multiple font families separated by commas in your CSS file. The browser will then attempt to use the first available font in the list.

Here’s an example:

body {
  font-family: Arial, Helvetica, sans-serif;
}

In this example, if Arial is not available, the browser will try using Helvetica as a fallback font. If both Arial and Helvetica are not available, it will resort to using a generic sans-serif font.

By providing fallback font options, you can ensure that your Next.js application maintains a consistent visual experience for all users, regardless of their device or operating system.

Methods to Add Custom Fonts

In the previous section we discussed what custom fonts are, but to use a custom next js font there are several ways.

Let’s explore a few of these methods:

Host the font files directly

One way to integrate custom fonts is by hosting the font files directly in your project. This method allows you to have complete control over the fonts and eliminates the need to rely on external sources.

To host the font files, follow these steps:

  • Place the font files in a directory within your Next.js project. For example, /public/fonts/.

  • In your CSS file, use the @font-face rule to specify the font family and the path to the font files. Here’s an example:

@font-face {
  font-family: 'MyCustomFont';
  src: url('/fonts/MyCustomFont.woff2') format('woff2');
}
  • In your CSS file, apply the custom font to the desired selector using the font-family property:

body {
  font-family: 'MyCustomFont', sans-serif;
}

Link to external sources

Another popular method of integrating custom fonts is by linking to external sources. Platforms like Google Fonts and Adobe Fonts offer a wide range of fonts that you can easily incorporate into your Next.js project.

To link to an external source, follow these steps:

  • Find the desired font on the external source website (e.g., Google Fonts).

  • Follow the instructions provided by the external source to obtain the necessary CSS link or code snippet.

  • Include the CSS link or code snippet in your Next.js application, either within a specific component or in the <Head> section for global availability.

Here’s an example of adding a Google Font to your Next.js application:

import Head from 'next/head';

export default function Home() {
  return (
    <div>
      <Head>
        <link href="https://fonts.googleapis.com/css2?family=Roboto:wght@400;700&display=swap" rel="stylesheet"/>
      </Head>
      {/ Rest of your component /}
    </div>
  );
}

When you are importing fonts from external sources it is recommended to put the correct links in the head section inside of document.js or _app.js file depending on your next version, to make them available globally and also add a prelaod flag so that they are fetched beforehand.

<link href="https://fonts.googleapis.com/css2?family=Roboto:wght@400;700&display=swap" rel="preload" as="style"/>

Using next/font

If you are using the latest version of Next Js then you can use next/font which is the recommended and the most efficient way to use Nextjs fonts. It is a built-in feature in next js that optimizes web fonts for performance. This font system automatically self-hosts any Google Fonts by including them at the time of deployment, so there are no external requests made for getting the fonts. This is different from the case where we used external font links.

Here is an example:

import { Inter } from 'next/font/google'
 
const inter = Inter({
  subsets: ['latin'],
  display: 'swap',
})
 
export default function RootLayout() {
  return (
    <html lang="en" className={inter.className}>
      <body>...</body>
    </html>
  )
}

If you check out the source code of the generated HTML then you will see a font being preloaded there

Handling Font Variants and Styles

Next.js provides developers with the flexibility to manage different font variants and styles to create consistent and adaptive designs. This is particularly important for responsive design, where typography needs to adapt to various screen sizes and resolutions.

To handle font variants and styles in Next.js, you can specify multiple font weights and styles in your CSS. Here’s an example:

@font-face {
  font-family: 'MyCustomFont';
  src: url('/fonts/MyCustomFont-Regular.woff2') format('woff2');
  font-weight: normal;
  font-style: normal;
}

@font-face {
  font-family: 'MyCustomFont';
  src: url('/fonts/MyCustomFont-Bold.woff2') format('woff2');
  font-weight: bold;
  font-style: normal;
}

In this example, we define two different font faces for the same font family, one for the regular weight and one for the bold weight. By specifying the appropriate font-weight and font-style properties, you can ensure that your typography adapts correctly to different styles and weights.

By effectively managing font variants and styles in your Next.js application, you can create visually appealing designs that are consistent across various devices.

Best Practices for Using Fonts in Next.js

To ensure optimal performance and user experience, it’s important to adhere to best practices for using fonts in Next.js. Here are some key best practices:

  • Minimize the number of font variants: Each additional font variant adds to the overall file size and loading time. Minimize the number of font variants used in your Next.js application to optimize performance.

  • Define fallback fonts: Always provide fallback font options to ensure compatibility across different devices and operating systems. Use generic font categories like sans-serif or serif as fallbacks.
