Accelerating Your Website: Embracing System Fonts for Enhanced Speed

Written by Daily Fix - Published 12-Dec-2023, last updated 21-Jun-2024

In today's digital landscape, website performance is paramount. A sluggish website can lead to increased bounce rates, decreased engagement, and a tarnished reputation. So web developers are always seeking ways to speed up the websites they build.

One significant factor affecting website speed is font loading. Google Fonts, a renowned resource for web fonts popular with web developers, provides a vast library of beautiful and versatile fonts. However, relying solely on Google Fonts can introduce unnecessary delays and hinder website performance.

So what's the answer? Take a bow system fonts...

How web fonts can impact web page performance

When a web page is requested from the web server, and prior to text rendering in the browser, web fonts must be loaded for users to view content on your page.

The browser only recognises web fonts after the HTML is loaded and the CSS files are processed. This process can be time-consuming, particularly if there are multiple web fonts that need to be loaded based on the website's design, potentially causing delays in page load times.

As a result, visitors may encounter the Flash of Invisible Text (FOIT) issue, in which the text is prepared for display but the web font has not yet been loaded.

What is Flash of Invisible Text (FOIT)?

The Flash of Invisible Text (FOIT) is a frustrating issue encountered when loading web pages, where text briefly appears blank before rendering the actual font. This occurs when using web fonts that require a short time to load and render on the screen, resulting in a flash of invisible text before being properly displayed. The FOIT problem can lead to poor user experience as it disrupts the visual flow of content on a website.

Several factors contribute to the FOIT issue, including slow network connections and large font files that take longer to download and render. The imact of the FOIT problem can be reduced by using system fonts rather than fonts whoch need to be downloaded.

Boost the performance of your website using system fonts

System fonts, also known as web-safe fonts, are fonts that are already installed on most users' devices. This means that they don't need to be downloaded from a remote server, eliminating the latency associated with network requests. As a result, websites that utilise system fonts load significantly faster than those relying on external font sources like Google Fonts.

Benefits of using system fonts

There are many benefits to using system fonts. These include:

Reduced Load Times: System fonts eliminate the need to download additional resources, significantly reducing page load times. This enhanced performance not only improves user experience but also boosts search engine rankings.

Reduced HTTP Requests: By not having to fetch font files from an external source, using system fonts can reduce the number of HTTP requests, further improving performance.

Simplified Deployment: System fonts are already integrated into the user's device, eliminating the need to manage and host font files. This simplifies website development and maintenance.

Enhanced Affordability: System fonts are typically royalty-free, eliminating the need to secure licenses or pay for fonts. This can significantly reduce development costs.

Cross-Platform Compatibility: System fonts are compatible with a wide range of operating systems and devices, ensuring consistent presentation across different platforms.

Reduced Network Traffic: By utilising system fonts, websites generate less network traffic, contributing to a more efficient and sustainable web experience.

How to use system fonts - CSS syntax

To use system fonts on a website you need to use the font-family CSS property to set the primary font-family for the website as follows:

body {
font-family: system-ui, sans-serif;
}

The CSS code above tells the browser to use the default system font (system-ui) and fall back to using sans-serif if there are any problems using the system font.

Conclusion: Use system fonts to help speed up your website

By embracing system fonts, website developers can significantly enhance website performance, reduce load times, and improve user experience.

System fonts offer a plethora of advantages, including simplified deployment, reduced network traffic, and enhanced cross-platform compatibility. As a result, leveraging system fonts is a strategic decision that can contribute to a more efficient, user-friendly, and performant website.
