The Math / Science
The ideal viewing distance is also based on the size of the television, and is the perfect distance away from the screen you should be sitting when you watch. The calculation for this is your TV size, divided by 0.55. As a quick reference, for a 42” television, the optimal viewing distance is 76 inches away. For a 55”, you’ll want to be 100” away.
The optimal viewing for 65” TVs is 118”, and for 70” televisions, you’ll ideally want to be 127” away.
