I need a new TV and want to put it into a cupboard. The dimensions I have are 75 cm wide and 55 cm high (this includes the stand it will be standing on). So what inch screen do I need?
Screen size is usually measured diagonally but then you also have to allow for the screen frame, so as gsr suggests you'd best go and physically measure I think.
Personally I would go to Currys/Comet etc etc measure tv's and when I find one I like make a note of the model number then go home and buy it cheaper online!
