I'm looking to get a HD tv but have had a near impossible time trying to find actual screen size dimensions. How much bigger (hight + width) is a 40" 16:9 tv vs say a 27" 4:3 tv?

Here is the website I found to help.

Took me forever to find this so I thought I would share it here.

Thanx, Jeff...I was looking for something like this!

great site, thanks.
