Page Size Checker
A heavy page loads slowly, and slow pages lose visitors. Paste any web address below and the Page Size Checker loads the page, adds up the HTML, images, scripts, stylesheets, fonts and media, and shows you the total weight in seconds. You also see which file types take the most space and which single files are the largest, so you know exactly what to shrink first.
We load the page and its images, scripts and stylesheets, then add up their sizes. Nothing is stored.
Paste the full address of any page (for example example.com or https://example.com/blog), press "Check page size", and in a few seconds you will see the total weight, the size by file type and the largest files to shrink first.
What is the Page Size Checker?
Page size (also called page weight) is the total amount of data a visitor's browser must download to show a page: the HTML document plus every image, script, stylesheet, font and media file it uses. The Page Size Checker loads any page you give it, measures each of those files and adds everything up, so you can see exactly how heavy the page is and what makes it heavy.
What does this tool do?
Paste a web address and the tool fetches the page, finds the images, scripts, stylesheets, fonts and media linked in it, measures each file and reports the total size. You get the overall weight, a breakdown by file type, a list of the largest files and a simple verdict on whether the page is light, average or heavy.
How to use the Page Size Checker
- Paste or type the full address of the page you want to check, for example example.com or https://example.com/blog.
- Press "Check page size" and wait a few seconds while we load the page and its files.
- Read the total page size, the size of the HTML document and how many files were loaded.
- Look at "Size by file type" to see whether images, scripts or stylesheets take the most space.
- Open "Largest files" to find the single heaviest files — shrinking those usually gives the biggest speed win.
Key features

Largest files list
The ten heaviest files on the page, so you know exactly what to shrink first.
Speed verdict
A plain-English rating: light, average or heavy, based on the total size.
Benefits
- Faster pages keep more visitors — most people leave a page that takes more than a few seconds to load.
- Page speed is a confirmed search ranking factor, and page weight is one of the biggest causes of slow pages.
- Knowing which files are heaviest turns "make my site faster" into a short, clear to-do list.
- Free and unlimited: check as many pages as you like, no account needed.
Common use cases
- A blogger checks why a post feels slow on mobile and finds a 4 MB hero image.
- A shop owner compares their homepage weight before and after installing a new plugin.
- A developer verifies that a redesigned page got lighter, not heavier, before launch.
- A freelancer sends a client a simple report showing which files make their site heavy.
Important limitations
- We measure the files linked directly in the page. Content loaded later — ads, videos that start on click, or endless scrolling feeds — may add more weight in a real visit.
- Some websites block automated checks or need a login; those pages cannot be measured.
- Sizes are the download sizes reported by each server, which can vary slightly between checks.
Frequently asked questions
Is this Page Size Checker free?
+
Yes. It is completely free and you can check as many pages as you like — no account needed.
Why is my result different from other tools?
+
Every tool measures a little differently. We add up the HTML document and the files linked directly in the page. Some tools also load ads, videos or content that appears after scrolling, which can make their totals higher.
Does a big page size hurt my Google ranking?
+
Page speed is a confirmed ranking factor, and page size is one of the biggest causes of slow pages. A lighter page loads faster, which helps both your visitors and your search visibility.
Why could you not check my page?
+
Some websites block automated checks or require a login. If a site refuses the connection or returns an error, we show you the message it sent back.
Do you store the pages I check?
+
No. We load the page, measure it and forget it. The address and the results are not saved.
