I have always wanted to know this, and now I'm looking to buy a new TV it would be REALLY handy. So, um, does anyone know, or can they figure out the dimensions of the SCREEN of a Widescreen TV?

For instance I'd like to know the HEIGHT and WIDTH of the SCREEN (not the actual TV) for a 32" 16:9 TV or a 42" or a 50" etc.

Does such a list exist anywhere?

Thanks!

Since the measurement is the diagonal of the screen, a perfect 16:9 screen would be advertised size times .49 high and times .872 wide.

Example:

32" = 15.7 x 27.9
42" = 20.6 x 36.6
50" = 24.5 x 43.6
53" = 26.0 x 46.2
55" = 27.0 x 47.9
57" = 27.9 x 49.7
64" = 31.4 x 55.8

Of course, this is not a perfect world and these are rough estimates only.

It's just simple trig. A rectangle that is 16" wide by 9" tall, will have a 18.36" diaganol. So just use this relation for other diagonals.

Example
a 16:9 34" set will have:
Width = (16/18.36")x(34") = 29.63"
Height = (9/18.36")x(34") = 16.67"

A 4:3 set is even easier since a 4" wide by 3" tall rectangle has a 5" Diaganol:
Width = (4/5)x(Diaganol)
Height = (3/5)x(Diaganol)

Wow! Thanks for that you guys! I guess the words "simple" and "trigonometry" don't go together in my vocabulary!

Here's some more measurements for anyone else:

32" = 15.7 x 27.9
34" = 16.7 x 29.6
36" = 17.6 x 31.4
40" = 19.6 x 34.9
50" = 24.5 x 43.6
60" = 29.4 x 52.3

And the revised link (the last one didn't work for me!):

Thanks again!
