How can I fix layout-shift issues caused by font-loading?

Asked on Oct 02, 2025

Answer

To address layout-shift issues caused by font-loading, you can use the "font-display" CSS property to control how fonts are rendered during loading. This helps improve the Cumulative Layout Shift (CLS) metric by ensuring text remains readable and stable.

/* CSS for font-display */
    @font-face {
      font-family: 'CustomFont';
      src: url('customfont.woff2') format('woff2');
      font-display: swap;
    }

Additional Comment:

Using "font-display: swap" allows the browser to use a fallback font until the custom font is fully loaded, minimizing layout shifts.
Ensure fallback fonts have similar metrics to custom fonts to reduce noticeable shifts.
Consider preloading critical fonts using the "link rel='preload'" tag to speed up font loading.
