Custom web fonts add real visual polish, but poorly implemented font loading is a common, underappreciated cause of slow page rendering.
Limit the Number of Font Weights and Styles Loaded
Every additional font weight or style is a separate file to download; loading only the specific weights actually used on the page meaningfully reduces load time.
Use Font-Display Settings to Avoid Invisible Text
Configuring how a browser handles the gap between page load and font load prevents text from being invisible during that window, improving perceived performance.
Consider System Fonts for Non-Critical Text
Using a visitor's own device fonts for less brand-critical text elements avoids a custom font download entirely for that content.
