Guide
Projector viewing distance
How far to sit from a projector screen, by size. A reference table of recommended seating distance for 80 to 200-inch 16:9 screens.
Guide
A common guide is to sit about 1.2 to 2 times the screen WIDTH away. For a 100-inch 16:9 screen (87 inches / 7.3 ft wide) that is roughly 9 to 15 feet. Closer is more immersive (THX); further is more relaxed (SMPTE).
Seating distance is a comfort and immersion choice, not a hard rule. About 1.2x the screen width fills your view like a front cinema row (THX ~36 degrees); about 1.6x matches the SMPTE 30-degree reference; beyond 2x the extra detail of a big 4K image is wasted. The table gives the range per size.
Recommended viewing distance by screen size

| 100″ | 8.7 ft–14.5 ft |

| 150″ | 13.1 ft–21.8 ft |
| 200″ | 17.4 ft–29.1 ft |
