# Too many font files are downloaded

`perf/too-many-fonts` · severity **warn** · category Performance · detected by `void perf` and `void audit`

## Why it matters

Each font file is a separate request that competes with the LCP resource and can cause a separate text reflow.

## How to fix it

Keep to ≤ 2 families and ≤ 4 files per route. Prefer a variable font over several static weights.

## More performance rules

`void perf` reports 25 rules in this category. Core Web Vitals and bytes: LCP, CLS, TBT, TTFB, JavaScript, CSS, fonts, images, caching and compression, measured as the median of several runs on a throttled mobile and a desktop profile.
