What are the best practices for optimizing font loading to improve page speed?
Asked on Mar 27, 2026
Answer
Optimizing font loading is crucial for improving page speed and reducing layout shifts. By using techniques like font-display and preloading, you can enhance the user experience and meet Core Web Vitals metrics.
Example Concept: To optimize font loading, use the "font-display" property in CSS to control how fonts are rendered. The "swap" value is commonly used to ensure text is visible while the font loads, preventing invisible text during loading. Additionally, preloading fonts using the tag can prioritize font loading, reducing the time to first render.
Additional Comment:
- Use "font-display: swap;" in your @font-face CSS rule to ensure text remains visible during font loading.
- Preload key fonts with to prioritize their loading.
- Limit the number of font weights and styles to reduce the overall font file size.
- Consider using system fonts for faster loading times, as they do not require additional HTTP requests.
- Ensure fonts are served in modern formats like WOFF2 for better compression and faster loading.
