TV Size and Viewing Distance Calculator
TVs are sold by their diagonal, which says little about whether one will fit your wall. Enter the screen size to see its actual width and height and a recommended viewing distance.

The math behind it: TV Size and Viewing Distance
width = diagonal x 16 / 18.36; height = diagonal x 9 / 18.36 (for a 16:9 screen)
A 55 inch TV is 47.9 inches wide and 27 inches tall, not counting the frame. For a cinema-like picture that fills 40 degrees of your view, sit about 5.5 feet away; for everyday viewing at 30 degrees, about 7.5 feet. These are guidelines, so adjust to suit your room.
Common questions
How wide is a 55 inch TV?
About 47.9 inches wide and 27 inches high for the screen alone. Allow an extra inch or so each way for the frame.
How far should I sit from a 65 inch TV?
Between about 6.5 and 8.8 feet. The closer figure gives a more immersive, cinema-style picture, and the farther one suits general viewing.

Diagonally, from one corner of the screen to the opposite corner, without the frame.
