Web Typography Performance & Core Web Vitals

Optimizing Web Typography for Core Web Vitals

Font loading speeds impact your site's performance and SEO rankings. Loading too many custom fonts or weights can delay rendering and cause cumulative layout shifts (CLS).

Optimize your setup by using system font stacks as fallbacks and checking load times with the Google Fonts Speed Tester. This keeps your site responsive and easy to load.

Minimizing Core Layout Shifts

When a custom font loads slowly, the browser displays a fallback font first, causing text to shift when the custom font renders. Proper fallback declarations minimize this layout shift, preserving page stability and search visibility.
