Frequently Asked Questions
How far should I sit from a 55 inch TV?
For a 55 inch 4K TV, the optimal viewing distance is 7.3 feet (2.2m) based on SMPTE standards. The comfortable range is 5.5-11.5 feet.
For a more immersive THX experience, sit 5.5 feet away. This closer distance fills more of your field of view, similar to a cinema experience.
What size TV for 10 feet viewing distance?
For a 10 feet (3m) viewing distance, the recommended TV size is 60-75 inches for 4K TVs.
A 65 inch TV is the sweet spot, providing optimal viewing based on THX and SMPTE standards. This gives you an immersive experience without requiring head movement.
Is bigger TV always better?
Not always. Too large a TV for close viewing can cause eye strain and neck fatigue. Follow the THX formula: minimum distance = screen diagonal × 1.2 for 4K TVs.
The maximum comfortable distance is screen diagonal × 2.5. Beyond this, you'll miss details and the viewing experience suffers.
What's the difference between 4K and 1080p viewing distance?
4K TVs can be viewed 25-30% closer than 1080p TVs without seeing pixels.
For a 65 inch TV: 4K minimum distance is 3.9 feet, while 1080p minimum is 7.8 feet. This allows larger TVs in the same space with 4K resolution.
