I am trying to find the dimensions for the various tablets screens, for example what would the sides be on a 7 inch diagonal screen. Not looking to be too exact, just approximations for the various diagonal measures. Thanks for the help.

It varies by tablet, not just by screen size. There are 7" tablets (Nexus7) that has a 1280x800 pixel screen, where as the Coby 7042 7" only has 800 x 480. 10" tablets range from 1024x768 (Archos 101) up to the TF700 & A700 have a 1920 x 1200 screen. Here is a site you can compare them at: http://www.tabletpccomparison.net/

Thanks for the link. What I am really looking for are the approximate dimensions in inches. For example, a 10 inch diagonal could be 6" by 8" on the sides, or a 7 inch diagonal could be approximately 5" by 5". Just looking for a general idea for the different screens out there, 7,8,9,10 inches.
