TV Size and Viewing Distance Calculator
Enter how far your main seat is from the screen to see the immersive and comfortable screen size ranges.
Result
- Immersive (THX-style)
- 90 in
- Comfortable (SMPTE-style)
- 68 in
- Casual living room
- 54 in
These are guidelines. Try taping the outline of a screen size to the wall to see how it feels from your seat.
How this calculator works
THX recommends about a 40 degree viewing angle, roughly screen diagonal = distance / 1.2. SMPTE suggests a more relaxed 30 degrees, roughly distance / 1.6. With 1080p sources we cap the immersive size a little, because sitting that close can show pixels.
