TV Size Comparison

TV size comparison
How is a TV measured? The inch size is the diagonal across the screen (not the width), and 1 inch = 2.54 cm. So a 65″ TV has a diagonal of 65 × 2.54 = 165 cm. Drag the pink screen over the purple one to compare.
Choosing the right TV size
Bigger isn't always better — the right TV size depends on how far you sit from the screen. Use this comparison to see how different diagonals actually compare, and convert between inches and centimetres for international specs.
Frequently asked questions
How is TV screen size measured?
TV sizes are measured diagonally across the screen in inches. This tool converts that diagonal between inches and centimetres and shows the screen to scale.
What's the difference between 55 and 65 inch TVs?
A 65-inch TV is roughly 18% larger diagonally than a 55-inch one, but the actual screen area is about 40% bigger because area grows with the square of the diagonal.
Can I compare multiple TV sizes at once?
Yes — pick several sizes and the tool displays each one to scale so you can see exactly how much bigger one is than another.
