Find the right TV size for your space.
Calculate screen dimensions, estimate a comfortable viewing distance or work backwards from your seating position to find TV sizes worth considering.
TV size calculator
Enter how far you sit from the screen. The calculator estimates a practical screen-size range using two viewing-distance multipliers.
Your viewing setup
Measure from your usual seated eye position to the screen.
How to interpret the result
Balanced: a useful starting point for mixed TV, films and streaming.
Immersive: favours a larger screen at the same seating distance.
Relaxed: favours a smaller screen or sitting farther back.
The suggested range is based on screen diagonal, not the outside dimensions of the television. Personal preference, eyesight, content and room layout all matter.

What these dimensions mean
These figures describe the visible 16:9 screen area only. They do not include the bezel, frame, feet or stand. Check the manufacturer’s model specifications before measuring furniture or planning a wall mount.

Your TV details
Distance is personal
There is no single perfect viewing distance for every person or room. Screen resolution, visual comfort, content and individual preference affect what feels right.
The everyday and immersive estimates use simple diagonal multipliers. The Full HD estimate is a broader planning reference, not a strict limit on what you can see.
