WHICH WIDE SCREEN HAS SAME VERT. HEIGHT AS MY 36

Hey guys,
Pull out your tape measures!
First off, were measuring screens here, not something else!
LOL.
Seriously, I own a 36" Sony Wega KD-36XS955 4:3 CRT HDTV and the actual screen height, vertically, is 22 1/2 high.
This does not include the chassis, only the actual screen itself.
I like the vertical height of my Sony, but I want a wide screen tv for HD and movies with the 16:9 aspect ratio. I want the actual screen height at least the same vertical height as my 36 incher.
My question is this:
On wide screen tv's, what MINIMUM size would I need to buy to AT LEAST EQUAL the 22 1/2 vertical height of my 36" 4:3 screen Sony CRT?
Remember, this is the actual screen itself, and does NOT include the chassis.
One friend said a 46", another friend said a 50" wide screen, but I need more solid answers from actual owners of wide screens. Neither of my friends actually owns one!
Any help at all would be greatly appreciated.
Thanks.
