    What's the rule of thumb for viewing distance vs how big the screen should be? I sit about 9-10' away from my 25" tv in a 12'x13' room and it's a bit too small. I try to judge from floor displays at electronic stores but due to the size of the showroom it's just not the same.

    The 'formula' is, for a high-definition signal, you should view from a distance of 3.3 times the picture height. For interlaced NTSC, it's 8 times the picture height, but since all the HD sets perform line-doubling (at least), a better figure to use is 5 times the picture height.

    Based on this, a widescreen set around 51" diagonal would be in order for your viewing distance.

    You can use this Viewing Distance Calculator to get the THX recommended distance (based on viewing angle) or the SMTP distance based on resolution.

    I sit 8' from my 42". With that viewing calculator I would pay most attention to the last section, visual acuity. There's no way I would sit so close to my TV based on the viewing angle numbers.

    I am going for a 40" and I will be sitting 14' feet away. You should be OK with a 32", but I would just go the distance for the 36".
