Page Size Checker – Check HTML Page Size & Load Speed Free
Check the HTML page size, server response time, and image count for any URL. Identify oversized pages that slow SEO crawling. Free, instant.
What is Page Size Checker?
A page size checker fetches a webpage and measures the raw HTML document size in kilobytes and the server response time in milliseconds. Large HTML pages slow down both user loading and Googlebot crawling — Google has a crawl budget for each site, and oversized pages consume it faster. Our tool also counts images to identify pages that may need lazy loading.

Frequently Asked Questions
What is a good HTML page size?
Google recommends keeping HTML documents under 100KB. Pages under 500KB are generally fine. Over 500KB may slow crawling and rendering — consider minifying HTML and reducing inline content.
What is crawl budget?
Crawl budget is the number of pages Googlebot will crawl on your site in a given period. Oversized pages, slow responses, and excessive redirects all waste crawl budget, potentially leaving important pages uncrawled.
