TV Size Chart: Screen Dimensions & Viewing Distance

Quick answer

TV size is the screen diagonal. A 55 in 16:9 TV is about 47.9 in wide and 27.0 in tall, and 4K viewers can sit about 1 to 1.5 times the diagonal away. Add 1-3 in for the bezel and stand.

How to measure a TV

  1. Measure diagonally from one corner of the screen to the opposite corner.
  2. Measure the width and height of the frame for your stand or wall space.
  3. Allow room for ventilation behind the TV.

Choosing a size

Match the screen to your room, the same way you would check a mattress or bed frame for fit. Bigger rooms suit 65 in or more.
