Ways to Preload Fonts for Faster Web Page Load Times

When it comes to web design, every second counts. Research shows that users expect a web page to load in 2 seconds or less, and any delay can result in them abandoning the site. One factor that can significantly slow down a page load time is the use of web fonts.

However, with the use of font preloading, you can improve the user experience by making sure the fonts are loaded faster.

What is a Preload Font?

Preload font is a technique used to load font files before they are actually needed. This is done by adding a preload link or preload directive in the HTML head section. By preloading the font files, you ensure that the fonts are ready to use when needed, and the user doesn’t have to wait for them to load.

Web pages rely heavily on fonts to display text content. However, when a user visits a web page that uses custom fonts, the browser needs to download the font files before it can display the text correctly. This process can take time, especially if the font files are large or hosted on a slow server, which can result in a slower page load time and a poor user experience.

Preload font solves this problem by allowing the browser to download the font files in the background before they are actually needed. This is accomplished by adding a preload link or preload directive in the HTML head section, which instructs the browser to fetch the font files as soon as possible. By doing so, the font files are cached in the user’s browser, ensuring that they are ready to use when needed, and the text is displayed correctly without any delay.

How does preload font improve web page performance?

Preload font allows the browser to download and cache the font files before they are actually needed. This means that when a user visits your website, the fonts are already available, and the browser can render the text faster. This can lead to a better user experience as users don’t have to wait for the fonts to load.

How to Preload Font?

There are several ways to preload fonts, depending on your web page setup. You can use the preload link, preload directive, or the webfont loader plugin. The most common way is by using the preload link.

To use the preload link, add the following code in the head section of your HTML file:

<figure class="wp-block-table">
<table>
<tbody>
<tr>
<td>&lt;<strong>link</strong> rel=”preload” href=”/path/to/font.woff2″ as=”font” type=”font/woff2″ crossorigin&gt;</td>
</tr>
</tbody>
</table>
</figure>

Here, you specify the font file path, the type of file, and the cross-origin attribute. The cross-origin attribute is used to allow the loading of the font file from a different domain, which is useful if your fonts are hosted on a CDN.

By using the preload link, the font file is downloaded in the background while the rest of the page is loading. This means that when the font is actually needed, it’s already available and the user doesn’t have to wait for it to download. This can significantly improve the user experience and reduce the risk of users abandoning the page due to slow loading times.

Why Preload Font?

Preload font has several benefits, such as:

1. Faster Page Load Time:

Preload font can speed up page load times by allowing the browser to download and cache the font files before they are actually needed. This means that when a user visits your website, the fonts are already available, and the browser can render the text faster. This can lead to a better user experience as users don’t have to wait for the fonts to load.

2. Improved Core Web Vitals:

Google’s Core Web Vitals is a set of metrics that measure the user experience of a web page, such as loading speed, interactivity, and visual stability. Font loading can impact the Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS) metrics, which are important factors in Google’s ranking algorithm. Preload font can improve these metrics by ensuring that the fonts are available early in the page loading process.

3. Invisible Text:

When a user visits a web page, they may initially see unstyled text before the fonts are loaded. This can cause confusion and a poor user experience. By preloading the font, you can ensure that the text is visible from the start, which can improve the user experience.

4. Preloading Custom Fonts:

If you’re using custom fonts on your website, preloading them can be especially useful since they may not be available in the user’s system font library. This ensures that your web page will look the way you intended, regardless of the user’s device or browser. Without preloading custom fonts, users may see fallback fonts or a delay in rendering the text, which can impact the user experience.

FAQs:

Are there any Alternatives to Preloading Fonts?

Yes, there are several alternatives to preload font, such as using system fonts, limiting the number of custom fonts used, and using font-display CSS property. Using system fonts can improve page load times since they are w already available on the user’s device. 

Limiting the number of custom fonts used can also help reduce the file size and improve page load times. The font-display CSS property can help control how the font is displayed while it is loading, allowing you to provide fallback options for slower connections.

How can I check the impact of preloading fonts on my website?

You can use various tools to measure the impact of preload font on your website, such as Google PageSpeed Insights, GTmetrix, and WebPageTest. 

These tools can provide you with insights into page load time, font loading time, and other performance metrics. You can use this information to optimize your website further and improve the user experience.

Tips to Preload Font:

To ensure that preloading fonts is done correctly, keep the following tips in mind:

1. Use Modern Browsers:

Modern browsers have better support for preloading fonts and other web technologies. Make sure your website is optimized for modern browsers like Google Chrome, Firefox, and Safari, as they offer the best user experience.

2. Check Browser Support:

Before using the preload link, it’s important to check whether the browser supports it. You can use feature detection techniques to check browser support and provide fallback options for unsupported browsers. If preloading fonts is not supported, consider using a fallback font or a different method of preloading.

3. Preload Local Fonts:

If you’re using custom fonts or a WordPress theme, it’s a good idea to preload font files locally. This helps to avoid relying on external sources, such as CDNs, which may be slower or unreliable.

4. Use WOFF2 Font Format:

The WOFF2 font format is a compressed format that reduces the file size of font files, leading to faster loading times. Consider using this format for your font files to improve loading speed and overall page performance.

5. Use Resource Hints:

Resource hints are a set of HTML attributes that help the browser anticipate which resources will be needed next. By using resource hints, you can improve the loading of critical resources, including fonts. Examples of resource hints include the prefetch, pre-connect, and preload directives, which can be added to the HTML head section.

<figure class="wp-block-table">
<table>
<tbody>
<tr>
<td>&lt;!DOCTYPE html&gt;<br>&lt;<strong>html</strong>&gt;<br>&lt;<strong>head</strong>&gt;<br>&lt;<strong>meta</strong> charset=”UTF-8″&gt;<br>&lt;<strong>title</strong>&gt;Resource Hints Example&lt;/<strong>title</strong>&gt;<br>&lt;<strong>link</strong> rel=”preload” href=”style.css” as=”style”&gt;<br>&lt;<strong>link</strong> rel=”prefetch” href=”image.jpg”&gt;<br>&lt;<strong>script</strong> src=”script.js” defer&gt;&lt;/<strong>script</strong>&gt;<br>&lt;/<strong>head</strong>&gt;<br>&lt;<strong>body</strong>&gt;<br>&lt;<strong>h1</strong>&gt;Resource Hints Example&lt;/<strong>h1</strong>&gt;<br>&lt;<strong>p</strong>&gt;This is an example of using resource hints in HTML to preload or prefetch resources.&lt;/<strong>p</strong>&gt;<br>&lt;/<strong>body</strong>&gt;&lt;/<strong>html</strong>&gt;</td>
</tr>
</tbody>
</table>
</figure>

6. Limit the Number of Fonts:

Using too many fonts on a web page can slow down its loading speed. Every font added to the page requires the browser to download additional files, which increases the page size and the amount of time it takes to load.

To avoid this, it’s recommended to use a maximum of 2-3 fonts per page and only use the styles that you actually need. This not only speeds up the loading time but also helps maintain a consistent design aesthetic throughout the page.

7. Consider Fallback Fonts:

Fallback fonts are an important consideration when preloading fonts. In case the font fails to load, a fallback font will be used to ensure that the text is still readable. It’s important to specify a fallback font in the CSS to ensure that the text is still readable even if the preferred font doesn’t load.

It’s recommended to choose a fallback font that is similar in style to the preferred font to maintain consistency in design. By specifying fallback fonts, you ensure that the user can still access the content even if the font fails to load, resulting in a better user experience.

Can Preload Fonts Cause Any Issues?

Preloading fonts can sometimes cause issues if not implemented correctly. For example, if you preload too many fonts, it can slow down the page load time, defeating the purpose of preloading. Additionally, if you use a font that is not supported by some browsers, it can cause compatibility issues. 

It’s important to test your website thoroughly after preloading fonts to ensure that everything works correctly.

Conclusion:

In conclusion, preloading fonts is a valuable technique for improving the performance and user experience of your website. By preloading fonts, you can reduce page load times, improve core web vitals, ensure text is visible from the start, and ensure that custom fonts are displayed correctly.

To make the most of preloading fonts, it’s important to use modern browsers, check browser support, preload local fonts, use the WOFF2 font format, and use resource hints. Additionally, it’s important to limit the number of fonts used on a page and consider fallback fonts in case of font loading failures.

Overall, preloading fonts is a simple yet effective technique for optimizing your website’s performance and ensuring a better user experience. By implementing these tips and best practices, you can make the most of preloading fonts and improve your website’s speed, functionality, and overall appeal.
