Why this matters for the Core Web Vitals, and where to start fixing it
Every font face is a separate file, and most sites load one per weight and style. Three families with three weights each is nine downloads of render-path bytes. Text either waits for them or reflows as they land, one by one.
The audit is quick: which weights actually appear above the fold? A variable font collapses a whole family of weights into one file. A system font stack costs nothing at all.
How does this affect the Core Web Vitals?
Fonts per page correlates with the LCP. Font count separates passing sites from failing sites more than font weight does. Where the font count is low, 88% of sites pass the LCP. Where it is high, 68% do. The decline is gradual. There is no point where sites suddenly start failing.
