Importance of Maintaining Viewing Distance While Watching TV

Personal taste, the location in the room, the resolution of the TV pictures you are watching and even the quality of your eyesight can affect your opinion of the right size of TV for your room.

You can put two different people in the same room, with the same size TV, and both may well have a different opinion of the right size screen for that room and the best viewing distance.

However, it can help to get some solid numbers to give us a starting point, so let us consider how we might do this. There are two ways to approach the issue:

Decide on your screen size and calculate the ideal viewing distance
Estimate your viewing distance and calculate an ideal screen size
A good rule of thumb is that the ideal viewing distance for a flat screen HDTV is between 1.5 and 3 times the diagonal size of the screen - and we can use this to calculate both approaches.
