Google Browser Size - Tool to see how others view your website

To help you understand how everyone sees your website, Google have created a tool called Browser Size. Browser Size is based on a sample of data from visitors to google.com. Special code collects data on the height and width of the browser for a sample of users. For a given point in the browser, the tool will tell you what percentage of users can see it. For example, if an important button is in the 80% region it means that 20% of users have to scroll in order to see it. If you're a web designer, you can use Browser Size to redesign your page to minimize scrolling and make sure that the important parts of the page are always prominent to your audience. People can use this tool to make their websites better, in turn making the web better for everyone.

To try it, simply visit browsersize.googlelabs.com and enter the URL of a page you'd like to examine. The size overlay you see is using latest data from visitors to google.com, so this should give you a pretty good indication of what parts of your UI are generally visible and what aren't.

How Google Browser Size Works

Google Browser Size is a visualization of browser window sizes for people who visit Google. For example, the "90%" contour means that 90% of people visiting Google have their browser window open to at least this size or larger.

This is useful for ensuring that important parts of a page's user interface are visible by a wide audience. On the example page that you see when you first visit this site, there is a "donate now" button which falls within the 80% contour, meaning that 20% of users cannot see this button when they first visit the page. 20% is a significant number; knowing this fact would encourage the designer to move the button much higher in the page so it can be seen without scrolling.

To view your own Web site with this same visualization overlaid on it, simply type its URL into the "Enter URL here" textbox at the top of the window and click Go.
