Page Size Checker
About Page Size Checker
Our Page Size Checker calculates the total file size of any webpage, including all HTML, CSS, JavaScript, images, and other resources. Page size directly affects loading speed - larger pages take longer to load, leading to higher bounce rates and lower search rankings.

Google uses page speed as a ranking factor, and a 1-second delay in page load time can reduce conversions by 7%. By knowing your page size, you can identify which elements are causing slowdowns and optimise accordingly.
Page Size Guidelines
- Ideal page size: under 500KB
- Acceptable: 500KB–1MB
- Needs optimisation: 1MB–3MB
- Critical issue: over 3MB
How to Use the Page Size Checker
- Enter the full URL of the page you want to measure.
- Run the check to have the tool fetch and total the size of the page's resources.
- Review the reported total size and compare it against the size guidelines above.
- If the page falls into the "needs optimisation" or "critical" range, identify likely culprits such as unoptimised images or unminified scripts.
- Re-check the page after compressing images or removing unused resources to confirm the size has improved.

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.
