Compare TV Sizes Side by Side
See exactly how much bigger one TV is than another — to scale, with real dimensions.
Pick two or three sizes to compare.
| Size | Width | Height | Screen area | vs 55" | Ideal 4K distance |
|---|---|---|---|---|---|
| 55" | 47.9″ | 27″ | 1,293 in² | — | 6.1 ft |
| 65" | 56.7″ | 31.9″ | 1,805 in² | +39.7% area | 7.3 ft |
| 75" | 65.4″ | 36.8″ | 2,404 in² | +86% area | 8.4 ft |
How this is calculated
Screen area grows with the square of the diagonal, so a small bump in
inches is a big jump in picture. For a 16:9 screen, area = (16 × 9 ÷ 337) × diagonal²: a 75" TV has 2,404 in² vs 1,293 in² for the 55" — about +86% more screen.
Compare TV sizes to scale
“Going up just 10 inches” is bigger than it sounds — because screen area grows with the square of the size. Pick any two or three sizes above to see them overlaid to scale, with the real width, height, and area difference.

How much bigger is a 65″ than a 55″?
A 65-inch screen is about 18% wider but 40% more screen area than a 55-inch — a much bigger jump than the 10-inch diagonal suggests. From 65″ to 75″ is another ~33% more area.
Which size is right for your distance?
The best size depends on how far you sit. Use the TV viewing distance calculator to match any seating distance to its sweet-spot size.
