How do we calculate?
The calculator uses international standards from SMPTE and THX. The key principle is field of view (FOV).
- 40° — THX Cinema: Ideal for movies where the screen fills a large portion of your field of view.
- 30° — SMPTE Mixed: Minimum recommended for sports and news. Provides a comfortable overview.
Why 4K?
Higher resolution means you can sit closer without seeing individual pixels.
4K (Ultra HD) gives you tremendous flexibility. The pixels are so small they are nearly invisible at normal viewing distances, allowing you to choose a larger TV even in smaller rooms.
8K is rarely necessary unless you sit extremely close to a very large screen (over 85 inches).
How to Measure Your TV
- Grab a tape measure.
- Measure the screen diagonally from corner to corner.
- Measure only the screen itself, not the plastic bezel.
- The result in inches is your TV's screen size.
Frequently Asked Questions
How far should I sit from a 55" TV?

How far should I sit from a 65" TV?
About 6.5 to 9 feet. Many experts recommend around 6.5 feet for the best immersion.
Can you sit too close to a TV?
It is not harmful to your eyes, but it can become fatiguing if you need to turn your head to see the entire picture (over 40° field of view).
Is 4K worth it?
Absolutely. It allows you to sit closer to large screens without the image looking grainy.
