    I have a old fashioned CRT TV that is 32 inch standard screen. I an considering buying a wide screen TV , possibly 37 inch. Does anyone know the difference in the two screen sizes ? ideally I would like a wide screen TV that has a screen size that is as "high" as my 32 inch, just several inches wider.

    You have discerned an issue that eludes most tv buyers who are upgrading from an
    older 4:3 AR set to a 16:9 AR widescreen display -- the vertical height of a 16:9 set
    of similar or slightly greater diagonal screen size is actually shorter than the 4:3 set,
    therefor characters and other things in a displayed image are smaller.

    Short of having a conversion table, I suggest you measure the vertical height of your
    4:3 set and go to a local electronics store with tape measure in hand so you can
    determine what 'size' HD display has an equivalent or greater screen height.

    Best of luck in finding just the right HD display for your needs.

    EDIT: I have a link to a conversion chart somewhere, but I don't have time to search
    for it at the present. I'll see if I can find it for you in the next day or two.

    A simple rule of thumb I use is to multiply a 4:3s display size by 1.2 . In other words, to get a 16:9 set that has the same vertical size as your 32" set, you'd need to a 16:9 set that measured 38.4 (32 x1.2), so you'll probably find a 40" or 42" will do the job. It's not perfect, but it'll get you close enough to fool the eye.

    A 42" widescreen is roughly equal to a 35 inch CRT. A 37 inch WS is roughly equivalent to a 30 inch CRT

    That's exactly why we got a 32 inch 16:9 to replace a 27 inch 4:3 that died...

    Great thread! I'm trying to talk my mother into letting me buy her a flat-screen HD TV to replace her 25" SD tube TV in the kitchen, and when we were out looking, she thought the 26" LCD looked too small and the 32" looked too big ...

    Now I just need to find a 30" LCD and I'll be all set! :lol:

    Thanks for the excellent table! I ended up doing a lot of math to convince Mrs. Shadow we needed a bigger TV when we upgraded.

    Here's how the math works for screen size:


    For wide screen (16:9):

    Width = 0.87 * Diagonal
    Height = 0.49 * Diagonal


    For narrow screen (4:3)

    Width = 0.8 * Diagonal
    Height = 0.6 * Diagonal
