📺 TV Size & Distance Calculator
Find the recommended viewing distance for your TV size, or the ideal TV size for your room.
TV Viewing Distance Guidelines
THX recommends a minimum viewing distance of approximately 1.2 times the screen diagonal for a cinematic experience. The SMPTE standard suggests a 30-degree viewing angle, which works out to about 1.6 times the diagonal. For casual viewing, up to 2.5 times the diagonal is comfortable.
Choosing the Right TV Size
Measure your viewing distance first, then divide by 1.6 for the ideal TV size. A 65-inch TV is ideal for about 8.5 feet away. With 4K resolution, you can sit closer without seeing pixels compared to 1080p displays.
