**The true dimensions of a 55-inch television depend on several factors, but a standard wide format screen has a height of 26.96 inches and a width of 47.94 inches.** A traditional format screen that measures 55 inches diagonally has a height of 33 inches and a width of 44 inches.

The height and width of screens with the traditional 4:3 aspect ratio can be determined for any size screen by multiplying the diagonal size by 0.6 to determine the height and 0.8 to determine the width. The height and width of a widescreen with a 16:9 aspect ratio can be determined by multiplying the diagonal size by 0.49 to determine the height and 0.87 to determine the width. The actual dimensions of the entire television depend on several factors, such as the size of the case and the bezel surrounding the screen.
