A 50-inch television’s length and width are determined by the area reserved for the bezel, however a wide-screen model with a 16:9 aspect ratio has dimensions of 43.58 inches wide and 24.51 inches high. A screen with a conventional 4:3 aspect ratio is 40 inches wide and 30 inches tall.
The dimensions of a typical screen with a 4:3 aspect ratio can be calculated for different screen sizes by multiplying the diagonal length by the values 0.8 and 0.6. Using the factors 0.87 and 0.49, wide displays with a 16:9 aspect ratio can be created. A standard bezel increases the screen size by 3 to 5 inches.
