Choosing the Right TV Size
Living room (8–12 ft): 55" to 75" is ideal for most living rooms. At 10 feet, a 65" 4K TV fills your field of view perfectly.
Bedroom (5–8 ft): 43" to 55" works well. The shorter viewing distance means you don't need as large a screen.
4K vs 1080p: With 4K, you can sit closer without seeing pixels, allowing a larger TV for the same room. 4K is worth it for any screen 50" and above.
THX standard: THX recommends a 36° viewing angle for cinema-like immersion. SMPTE suggests 30°. Our calculator uses both to give you a comfortable range.
