It's been way to long since I did algebra so I'm hoping someone can help me with this.

I have a 21" CRT 4:3 TV I need to replace. In looking at LCD flat screens, virtually all sold these days are widescreen 16:9. It may be a long time before I upgrade my cable to HD, so for the immediate future I would be using a widescreen 16:9 LCD TV to display a standard 4:3 TV picture, with the required black bars on both sides (assuming unzoomed).

So the question is, how big of a 16:9 widescreen (measured diagonally) TV do I need to display at least a 21" 4:3 picture?

Thanks for any help.

It is actually a little trigonometry. A good approximation is to get a set about 20% larger on the diagonal if you want the height to be the same.
