How to Compare Fonts Across Different Websites Side by Side

Choosing between two fonts using sample text on Google Fonts is like choosing a paint color from a swatch card — it gives you a rough idea but doesn't show you how it'll look on the wall. Fonts behave differently at different sizes, in different layouts, and with different amounts of text.

A better approach is to find real websites using each font you're considering and compare them in context. Font Detector makes this practical.

Say you're deciding between Inter and Nunito Sans for body text. Search for websites using Inter — run Font Detector on documentation sites, SaaS dashboards, and blog articles that use it. Then do the same for Nunito Sans. You'll see how each font handles long paragraphs, short UI labels, dense data tables, and everything in between.

Pay attention to specific characteristics. How does each font handle long lines of text? Some fonts feel cramped at 16px while others feel open and airy. How readable is each at small sizes like 12px or 13px? Fonts that look great as headings sometimes fall apart as caption text.

Font Detector gives you the exact specifications each site is using — size, weight, line height, letter spacing. If a site using Inter looks particularly good, note those exact settings. The font itself is only part of the equation — the sizing and spacing choices matter just as much.

This real-world comparison method takes more time than glancing at a font catalog, but it produces better decisions. You're evaluating fonts in the conditions they'll actually be used, not in the idealized conditions of a preview widget. The extra 15 minutes of research prevents the "this looked good in the preview but awful in my layout" problem that wastes hours later.
