7" Touch Screen Dimensions?

Hi,

Can anyone tell me the dimensions of the viewable window on a 7" LCD Touchscreen?

I need the length and height of the rectangular window of a 7" LCD Touchscreen.

Thanks for any tips.

for touchscreen info I usually go to densitron, http://www.densitron.com


One type of 7inch has a viewable area of
152.95 x 94.5 mm

but it looks like they vary

screens are measured diagonally, which creates a triangle.
if it is letterbox, it has a 16:9 ratio, standard is 3:4
so, if it is letterbox, working off the pythagoean theorem and 7" is the hyptenuse, you can calculate the length and width of the screen.
