Overview
Fonts shape a brand and also consume download and rendering time. Treating them as managed static assets reduces dependency on external requests and makes versions, caching and licensing easier to understand.
Confirm usage rights before preparing files
Downloading, changing or embedding a font depends on its license. Keep the license and source record, then choose formats, weights and character coverage according to actual pages.
- Load only weights and styles the page uses instead of downloading an entire family repeatedly.
- Check character coverage and fallback order for multiple languages.
- Version updated font files and retain their licensing information.
Keep font substitution from disrupting reading
Differences in width and line metrics can move content after a font loads. Choose a suitable fallback and check actual headings, buttons and numeric text.
Fallbacks
Provide system and appropriate CJK fallbacks so content remains readable while fonts load.
Display behavior
Choose a loading strategy suited to branding and reading instead of leaving text invisible for a long period.
Preload scope
Consider preloading only fonts needed for the current first view, not every font another page might use.
Maintain fonts like other static assets
Provide the right content type, cache policy and required cross-origin response. Test whether pages request duplicate files or display missing characters.
| Scenario | Check |
|---|---|
| First visit | Text visibility and font request order |
| Repeat visit | Cache reuse and version changes |
| Language switching | Character coverage, line height and wrapping |
| Mobile | File size, type size and layout stability |
