About the Page Size Checker
This tool fetches a page and measures the size of its HTML document in kilobytes, times how long the server took to return it, reports whether it was sent compressed (gzip or Brotli), and counts how many scripts, images and stylesheets the HTML references. It is a fast way to gauge how heavy a page is and where the weight is likely to come from.
Page weight is a real ranking and user-experience factor: heavy pages are slow, especially on mobile connections, and slow pages lose visitors. A bloated HTML document often points to inlined data or a page builder gone wild, while a large number of referenced scripts and images hints that the real payload — the part this measures the count of, not the bytes — is where to look next.
One honest limit: this measures the HTML document itself, not the total downloaded weight of every asset, because that would mean loading the whole page like a browser. Treat the asset counts as a pointer to what to investigate. For the response headers behind the load use the HTTP header checker, and for the status and redirects use the HTTP status checker.
Frequently asked questions
Does this measure the whole page weight?
It measures the HTML document size and counts the scripts, images and stylesheets it links to. It does not download every asset, so the total page weight will be larger.
What is a good HTML size?
There is no hard rule, but a lean HTML document is often well under 100 KB. Much larger usually means inlined data or a heavy page builder worth reviewing.
What does the encoding line mean?
It shows whether the server sent the page compressed with gzip or Brotli. Compression is on when it is not "none", and it substantially reduces transfer size.
Why is the load time different each check?
It depends on the server, network and caching at that moment. Run it a few times to get a feel for the typical figure.
