What are Variable Fonts?


(Interactive website by Fontsmith shows how variable fonts work)

Have you ever visited a website or a blog and see the font of the website change from an ugly design to a prettier one? That actually happens because of the delay in loading the website’s fonts. And it’s a quite common occurrence on slow-loading websites.

Variable fonts use CSS attributes for font-weight, font-style, and other font styling features without limitations

When designing websites, you use multiple fonts on the design. Including various weights of the font such as bold and thin. As well as different styles such as italics. You have to embed each font on your webpage in order for them to work. And when a visitor loads the page, it first downloads and renders the fonts one by one before it’s visible on the user’s device.

This adds more time to website loading, costs more server resources and bandwidth, and most importantly, it interferes with the overall user experience.

Variable fonts are a new type of fonts that use the power of CSS to convert different variations of axis using numeric values. Or, in laymen’s terms, variable fonts use CSS attributes for font-weight, font-style, and other font styling features without limitations.

So that instead of having to embed multiple fonts for showing different weights and styles, you only have to embed one font and change styles using CSS. Plus, you no longer have to limit yourself from sticking to a range between the fonts you have embedded. Like defining font-weight, for example. This gives you limitless opportunities to get creative with font designs without affecting the website performance.

How Variable Fonts Work

The technical side of the variable fonts is difficult to put into words without covering a whole list of definitions for terms and typography design. So we’ll try to explain how variable fonts work in simple terms.

When using a variable font, you can control the width of the font using CSS attributes and numeric values without affecting the design of the font.

A great way to look at the flexibility of variable fonts is how font-width works. Normally, when using a regular font on a website, you have little to no control over the font width. Or at least control it without affecting the quality and the design of the font. You are limited to using fonts with fixed-widths like condensed and narrow fonts.

When using a variable font, you can control the width of the font using CSS attributes and numeric values without affecting the design of the font.

For example, you can use a simple CSS attribute like h2 { font-stretch: 60%; } to stretch out the font to control the width of the font to create a different look for your H2 headings.

The same applies to italics, slants, font size, and more. The power of variable fonts lies in CSS. And that’s what makes them more responsive and effective than the old resource-heavy fonts.

There are some amazing experiments made with variable fonts in CodePen. Take a look if you want to get an idea of how variable fonts can be used in creative designs.

Why Use Variable Fonts?

By now you should have a basic understanding of how variable fonts can be beneficial in web design and development. As well as to make the web a better place.

To sum up, here are a few reasons why variable fonts are worth using in your designs:

  • Faster Websites: Without having to embed and load multiple fonts, websites will load much faster and cost fewer server resources
  • Creative Freedom: As designers, you can get creative with web designs without having to limit yourself to a set of fonts or font weights
  • Flexible Designs: With more flexibility, you can define widths, weight, and more without any limitations
  • Improve User Experience: There will be minimal delays in font loading and hopefully better compatibility for variable fonts in operating systems to offer a better user experience

But they may differ for some fonts. So it’s best to refer to each font documentation to understand how it works.
