Recommended Viewing Distance
Optimal viewing distance depends on screen size, resolution, and type. Too close causes eye strain; too far reduces detail visibility.
General formulas:
TV (4K UHD):
Distance = Screen size × 1.0 to 1.5
TV (1080p HD):
Distance = Screen size × 1.5 to 2.5
Computer monitor (desk work):
Distance = 20 to 40 inches (50 to 100 cm) — at arm’s length
Phone:
Distance = 12 to 16 inches (30 to 40 cm)
Common recommendations:
| Screen Size | 4K TV | 1080p TV |
|---|---|---|
| 43 in | 3.5–5.5 ft | 5.5–9 ft |
| 55 in | 4.5–7 ft | 7–11.5 ft |
| 65 in | 5.5–8 ft | 8–13.5 ft |
| 75 in | 6.5–9.5 ft | 9.5–15.5 ft |
