Where should the sofa sit from the TV? Slide it and see

The best sofa-to-TV distance comes from one idea: how much of your view the screen fills. Aim for roughly 30° to 40°, which for a 16:9 screen is about 1.2 to 1.6 times the diagonal.

Drag the sofa towards and away from the TV, change the screen size, and watch the viewing angle and comfortable range update. Then measure your own room before you move or buy anything.
