TV Viewing Distance Converter
Calculate optimal viewing distance for any screen size at 1080p, 4K, and 8K resolutions.
Enter your TV screen size to see the ideal viewing distance for each resolution.

Optimal viewing distance depends on screen size and resolution. Higher resolution allows you to sit closer without seeing pixels.
THX recommendation (for cinematic experience):
- Viewing angle of about 40 degrees
Society of Motion Picture and Television Engineers (SMPTE):
- Minimum 30-degree viewing angle
Resolution-based formulas: The minimum distance where pixels are not visible to normal vision (20/20):
- 1080p: Distance = screen height × 3.0
- 4K (2160p): Distance = screen height × 1.5
- 8K (4320p): Distance = screen height × 0.75
Screen height from diagonal:
- Height = diagonal × 0.49 (for 16:9 screens)
- Width = diagonal × 0.87 (for 16:9 screens)
Example for 55" TV:
| Resolution | Min Distance | Max Distance |
|---|---|---|
| 1080p | 2.2 m (7.1 ft) | 3.4 m (11.2 ft) |
| 4K | 1.1 m (3.5 ft) | 2.2 m (7.1 ft) |
| 8K | 0.5 m (1.8 ft) | 1.1 m (3.5 ft) |
All measurements assume a standard 16:9 aspect ratio display.
