Page Size Analyzer
Measure HTML size and count stylesheets, scripts, images, and iframes on any page.
What is Page Size Analyzer?
Page weight directly affects load time. The web's average page is ~2MB; sub-1MB pages feel snappy, 3MB+ pages feel sluggish. This tool measures HTML size and counts external resources — it doesn't fetch each one (use Lighthouse for full waterfall analysis), but the resource counts predict total weight.

Under 1MB for content sites, under 2MB for design-heavy. Mobile users especially appreciate small pages.
