When you’re designing a webpage, it’s important not to create a page that requires your audience to scroll side to side or up and down much in order to see your content (anNOYing!) But how can you know how big your viewers’ browser windows will be before you even put your page up on the web?
Google has released this great tool called browsersize. http://browsersize.googlelabs.com/
Basically, you type in the URL of a webpage in the text box at the top of the screen, and Browsersize shows you what percentage of people will be able to view a given portion of the page. It’s based on the browser window size of people who visit Google, so it should be a good estimate of the total population. It’s probably safe to assume that people on campus have higher resolution monitors than the public at large, so if you’re making a page specifically for a Penn audience, Browsersize should provide a conservative estimate for you.
