At present, the typical viewing distance for a 75-inch TV is between 6 and 10 feet (1.83 and 3.05 meters). This is because the average screen size of television has increased in recent years and most homes have enough space to accommodate a large TV.
However, it is not only the size of the room that determines the ideal viewing distance, but also the resolution of the TV. The higher the resolution, the closer you can be to the screen without losing image quality.
For example, Full HD TVs with 1920 x 1080 pixel resolution can be watched from a distance of 5 feet (1.52 m) without noticeable pixels. But if we have an Ultra HD 4K TV with a resolution of 3840 x 2160 pixels, the recommended viewing distance is only 2.5 feet (0.76 m).
This means that, in general, the ideal viewing distance for a 75-inch TV will be between 6 and 10 feet (1.83 and 3.05 m). But if the television has a 4K resolution, the ideal distance will be closer, between 2.5 and 5 feet (0.76 and 1.52 m).
As you can see, the TV dimensions of a 75-inch television will vary depending on the aspect ratio. The standard today is 16: 9, but there are still some old 4: 3 TVs in use.
If you want to know the dimension of 75-inch TV in detail, you must take into account the aspect ratio to calculate them correctly.
If the aspect ratio is 16:9, then the screen width is 166.0 cm and the height is 93.4 cm. The diagonal length of the screen is 190.5 cm.
However, if the aspect ratio of the TV is 4:3, then the screen width is 152.4 cm and the height is 114.3 cm. The diagonal length of the screen is 190.5 cm.
It is also important to take into account the viewing distance. The recommended distance to watch TV is usually between 2.5 and 4 times the diagonal length of the screen. That is, for a 75-inch TV, the ideal viewing distance would be between 250 and 400 inches (190.5 * 2.5 = 476.25 cm and 190.5 * 4 = 762 cm).

When buying a TV, it is important to consider the size of the screen according to the dimensions of the room where it will be located. A too-large television may not fit in the space available or, if it does, it can dominate and unbalance the decoration.
