Preloaded font count and the Core Web Vitals
7.8% of audited sites (15,743) preload 1 to 2 web fonts and reach 88% good LCP (1.3s median), whereas the 2.4% preloading 5 or more fonts drop to 86% good LCP (1.5s median).
86.6% of sites have no preloaded font count. Of the 13.4% that do, 58% use 1 to 2 preloaded fonts, and 88% of those sites have a good LCP, against 86% of all sites.
86.6% of sites have no preloaded font count. Of the 13.4% that do, 58% use 1 to 2 preloaded fonts, and 82% of those sites have a good CLS, against 78% of all sites.
Core Web Vitals pass rate
Sites with 1 to 2 preloaded fonts preloaded font count have a good LCP most often: 88%, against 86% of all sites. Sites with 3 to 4 preloaded fonts font preloads have it least often, at 86%.
Sites with 1 to 2 preloaded fonts preloaded font count have a good CLS most often: 82%, against 78% of all sites. Sites with 5+ preloaded fonts font preloads have it least often, at 77%.
Preloaded font count usage
13.4% of sites use preloaded font count, and three in five of those use 1 to 2 preloaded fonts.
LCP phase breakdown by number of preloaded fonts
Across the four LCP sub-parts in Chrome's field data, the largest gap between 1 to 2 preloaded fonts and 0 preloaded fonts sits in resource load delay: 395 ms median for 1 to 2 preloaded fonts against 260 ms for 0 preloaded fonts. Overall median field LCP is 1.4s for 1 to 2 preloaded fonts (TTFB 463 ms, load delay 395 ms, load duration 124 ms, render delay 230 ms) versus 1.4s for 0 preloaded fonts.

Understanding preloaded font count
Why preloading 1 to 2 fonts helps LCP while preloading 5+ fonts starves the hero image
Normally the browser discovers web fonts only after downloading CSS and matching @font-face rules to DOM nodes. Preloading 1 to 2 core WOFF2 files (7.8% of sites, 15,743) starts font fetches immediately and lifts good LCP to 88% (1.3s median), ahead of the 86.6% with 0 font preloads (86% good LCP, 1.4s median). However, preloading 3 to 4 fonts (3.3%) drops good LCP to 86% (1.4s median), and preloading 5 or more fonts (2.4%) saturates early bandwidth and drops good LCP to 86% (1.5s median).
Limit <link rel="preload" as="font" type="font/woff2" crossorigin> to at most 1 or 2 above-the-fold WOFF2 files, or consolidate weights into a single variable font file. Across all audited sites, 7.8% preload 1 to 2 fonts (88% good LCP) and 2.4% preload 5 or more (86% good LCP).
