How visible are the main areas on your website?

March 31, 2010

If you want to know how visible the main areas on a website page are to readers, head on over to Google’s Browser Size Labs to find out. Update 2014: In 2012, Google added this feature to Google Analytics, so as far as I know it’s only available to those who use Google Analytics (see: http://analytics.blogspot.com.au/2012/06/new-feature-conduct-browser-size.html).

Google Browser Size (http://browsersize.googlelabs.com/) 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.

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.

  1. A useful tool. I produced a desktop background image with gridlines showing different screen resolutions so that I can always check that my documents and designs work with several common screen resolutions without adjusting my monitor settings. I think that with the increase in netbook, iPhone and now iPad usage, the trend for ever-increasing screen resolutions has reversed somewhat.

  2. http://browsersize.googlelabs.com/ no longer resolves.

  3. Thanks Travis. It looks like they released it from Google Labs in 2012 and added it to Google Analytics: http://analytics.blogspot.com.au/2012/06/new-feature-conduct-browser-size.html. I don’t know if it’s still available there.

    I’ll update the post.
