Web Typography: Choosing Fonts That Load Fast and Read Well

Typography is around 90 percent of web design in one sense: most of what people do on your site is read. The right fonts make text easy to read and give your brand personality, but poorly loaded fonts can slow pages and cause layout jumps.

Choose for readability first

• Use a clear typeface for body text, at 16 pixels or larger.
• Keep line length to about 50 to 75 characters and line height around 1.4 to 1.6.
• Ensure strong contrast between text and background.

Limit the number of fonts

One or two typefaces are usually enough: one for headings, one for body text, or a single versatile family. Every extra weight and style adds to download size, so load only what you use.

Pair with care

Combine contrast with harmony: for example, a distinctive heading font with a neutral body font. Avoid pairing two similar-but-different fonts.

Load fonts efficiently

• Use modern WOFF2 files.
• Host fonts yourself or use a reliable service with preconnect hints.
• Use font-display: swap so text appears immediately in a fallback font.
• Consider variable fonts, which include multiple weights in one file.
• Subset fonts to the languages you need.
• Choose a fallback font with similar proportions to reduce layout shift.

Consider system fonts

System font stacks load instantly and look familiar. For some sites, especially content-heavy ones, they are a perfectly good choice.

Check licensing

Make sure you have the right to use fonts on your website, and keep records of the licences.
