Why this matters for the Core Web Vitals, and where to start fixing it

Page weight is a bandwidth problem. The network can only move so many bytes per second and every resource on the page competes for that capacity. The LCP image does not load alone. It shares bandwidth with every script, stylesheet and tracking pixel that loads at the same time. A heavier page means the main content arrives later.

Request count matters next to the bytes. Every request adds queueing and scheduling overhead. On a busy connection important requests wait behind unimportant ones. Script bytes keep costing after the download. The main thread has to parse and execute them, and that delays interactions (INP). The resource type breakdown shows where the bytes sit.

How does page weight affect the Core Web Vitals?

Page weight & requests correlate with the LCP. Page weight separates passing sites from failing sites more than request count does. Where the page weight is low, 83% of sites pass the LCP. Where it is high, 73% do. The decline is gradual. There is no point where sites suddenly start failing.
