Free Online Page Size Checker
Instantly check the total size of any webpage in KB and MB.
Why Does Page Size Matter?
The size of a webpage directly impacts its loading speed. Larger pages take longer to download, which can lead to a poor user experience and higher bounce rates. Search engines like Google also consider page speed as a ranking factor.
By checking your page size, you can identify if your page is too large and take steps to optimize it, such as compressing images and minifying code. This tool measures the size of the HTML document, which is the foundation of your page's total weight.

Understanding the Results & How to Improve
Excellent / Good Rating
This means your HTML document size is lean and well-optimized (typically under 100 KB). This is great for performance, as browsers can download and start rendering your page very quickly. No immediate action is needed, but always strive to keep your code clean.
Large Rating
A "Large" rating indicates that your HTML document size is excessive. This can be caused by "code bloat" from page builders, too many plugins, or large amounts of inline CSS and JavaScript. This will slow down your website. Here is how to fix it:
- Minify HTML: Use a tool (like our Code Minifier) to remove all unnecessary whitespace, comments, and line breaks from your code.
- Move CSS and JS to External Files: Large blocks of 'style' and 'script' tags inside your HTML add to its size. Move them to separate `.css` and `.js` files and link to them.
- Remove Unused Code: Audit your plugins, themes, and page builder elements. Deactivate and remove anything you are not actively using.
- Enable Gzip/Brotli Compression: Make sure your web server is compressing your files before sending them to the browser. This can dramatically reduce file size.
Use Cases
Performance Audits
As a first step in a website speed audit, checking the page size helps you quickly identify if a page is bloated. It's a simple check that can point to larger underlying performance issues.
Competitor Analysis
Quickly check the page size of top-ranking competitors. If their pages are significantly smaller and faster than yours, it highlights an area where you can gain a competitive advantage by optimizing your own site.

Check Size NowFrequently Asked Questions
What is a good page size?
While this tool measures the HTML document size, a good **total page size** (including images, CSS, and scripts) is generally considered to be under 2 MB. The smaller, the better. A smaller HTML document itself contributes to a faster initial page load (Time to First Byte).
Does this tool measure the size of images and scripts?
No, this tool specifically measures the size of the initial HTML document that is downloaded. The total size of a page also includes all external resources like images, CSS files, and JavaScript files, which are downloaded separately by the browser. However, a large HTML file is often a sign of a bloated and slow-loading page.
