Fonts power 87% of websites today
How do web fonts impact site speed?
Rising font file sizes
Web fonts are getting larger, slowing page loads—especially on mobile or slower connections. While WOFF2 adoption is growing, many sites still use uncompressed fonts or fail to subset unused glyphs, leading to inefficiencies and longer load times.
Improper loading strategies
Only 11% of websites use the most effective <preload> resource hint, while many still rely on outdated strategies like blocking text until fonts load—resulting in poor user experience, delayed content visibility, and failed Core Web Vitals.
Slower speed with icon fonts
Font Awesome and other icon fonts are used by 15% of websites, yet they’re notorious for performance issues. These fonts lack proper fallbacks, increase font file sizes unnecessarily, and often delay text rendering—hurting page speed and user experience.
