There are 65-inch, 75-inch, 98-inch and 100 inch TV screens, mainly depending on the size of the living room. The viewing distance of TV is generally between two and three times the size of TV. That is, the nearest viewing distance watched by the TV set = the size x2 of the screen; Farthest viewing distance = screen size x3; The best viewing distance is between the nearest viewing distance and the farthest viewing distance. For example, for a 60-inch TV set, according to 1 inch =2.54 cm and 60-inch = 152.4 cm, then the nearest viewing distance =152.4x2 = 304.8cm ≈ 3m; The farthest viewing distance =152.4x3 = 457.2cm ≈ 4.6m; Therefore, the best viewing distance of 60-inch TV should be between 3 meters and 4.6 meters, and the viewing experience is better.
