why does it matter? - a 32" telley is the same size as all the others (give or take an inch) (you can't really get a bigger one ... cause then its called a 37"
all you need are the case dimentions to see if it will fit
6 Months ago I bought a new Sony 40" HDTV (lcd) Model No KDL40W4000 and I cannot recommend it highly enough. You can look up reviews of this set and others on the internet. Sony are regarded as leaders in the field of LCD and Panasonic in the Plasma.
The choice is yours !!!!
You may find that although the screen size is measured corner to corner, with a larger older square 4:3 type tv screen you will not get as much vertical area as on a newer widescreen tv.
So a 32 inch widescreen tv my look and be a lot bigger than the 26 inch widescreen but may not be as big as an older 26 inch square screen.
