Web Typography Best Practices for Readable, Beautiful Sites

Typography makes up the vast majority of any website’s content, yet it’s often an afterthought. Get it right and your site feels polished and effortless to read. Get it wrong and even great design falls apart. Here are the web typography best practices that matter most.

Choose fonts with purpose

Limit yourself to one or two typefaces — typically one for headings and one for body text. Pair fonts that contrast but complement each other. Google Fonts offers a huge, free, performance-friendly library, and Fonts In Use is great for inspiration on real-world pairings.

Prioritise readability over personality

A characterful display font can work for a logo or hero headline, but body text needs to be effortlessly legible. Stick to well-hinted, screen-optimised fonts for paragraphs.

Get your base size right

Set body text to at least 16px (often 18px for long-form content). Anything smaller strains readers, especially on mobile. This also supports accessibility.

Mind your line length

Aim for 50–75 characters per line. Lines that are too long are hard to track; too short and the eye jumps constantly. The Butterick’s Practical Typography reference is an excellent, opinionated guide to this and much more.

Use generous line height

For body text, a line height of around 1.5–1.7 improves readability dramatically. Tight leading makes paragraphs feel cramped and harder to scan.

Establish a clear hierarchy

Use size, weight, and spacing to distinguish headings, subheadings, and body text. A consistent type scale — documented on resources like Type Scale — creates rhythm and guides the reader through your content.

Limit weights and styles

Loading a dozen font weights bloats your page. Pick the few you actually need. This keeps your site fast and your Core Web Vitals healthy.

Optimise font loading

Web fonts can slow your site and cause layout shift. Use font-display: swap, preload critical fonts, and consider variable fonts. Google’s web.dev has thorough guidance on fast, flicker-free font loading.

Don’t forget contrast and colour

Text must meet WCAG contrast standards against its background. Grey-on-grey may look trendy, but it fails real users.

The payoff

Thoughtful typography is invisible — readers simply find your content easy and pleasant to consume. That ease translates directly into engagement and conversions, the same goal behind every high-converting website. Want a site with a polished type system built in? Explore our web design service.
