What is the optimum distance for watching sd channels on 42" lcd?

Question

i'm planning to buy a 42 lg lcd, in a 4 meters (13 feet) room, the viewing distance will be about 10 to 11 feet, I'm wondering if 42" is too big for this distance and if the screen will be pixelated, should i consider a 37" model for this viewing distance or 42" is fine?

Answer 1

Almost right on.  It would be 10.5 feet.  They say that you multiply the diagonal (inches) by 3 and then divide by 12 to give you the distance in feet.  3x42=126/12= 10.5 feet.  You're good to go.
