Frequently asked questions
Is the Page Size Checker free?
This tool requires an active one-time membership to use - pay once and unlock this tool plus every other gated tool on the site, no subscription, no ads.
What is a good target page size?
Under 1-2MB total page weight is a reasonable target for fast loading on most connections - much larger pages, especially with unoptimized images, tend to load noticeably slower and hurt both user experience and Core Web Vitals scores.
What usually makes a page unexpectedly large?
Unoptimized/uncompressed images are the most common culprit, followed by too many render-blocking scripts and stylesheets, and unminified code.
