TV screens are measured diagonally from corner to corner, so a 65-inch TV is closer to 55 inches wide. Bigger is better, in most respects — it's more immersive and easier to see, not to mention more impressive when showing off to the neighbors.

The size of a television, often measured in inches, refers to the diagonal length of the screen—from one corner to its opposite (as shown in the image at the top). It’s not about the width or the height of the television, as some might assume.
