Why is the screen measured diagonally

The 55-inch diagonal is 139.7 centimeters. This size is easy to calculate the length and width of the TV, through the size of the monitor and frame. You can prepare a place for it before purchasing equipment.

The first picture tubes were spherical. The width and height of the screen could only be measured conditionally. Therefore, the size of the TV set was determined by the generatrix and was indicated in cm, and not in inches. Then the ray tubes were gradually shortened, the screen became less curved and rectangular.

The width and height of the product were at first 4: 3, then gradually domestic models switched to an aspect ratio of 9: 5.

Length converter centimeters to inches and vice versa.

Since the end of the last century, they began to produce domestic models with a ratio. width and height according to the international standard 16: 9. Ergonomics experts say that it is most convenient to see the picture at this aspect ratio.

Now the diagonal was characterized in English units of measurement and was the maximum. 32 inches. Television capabilities were limited. On a larger monitor, the picture turned out to be blurry, indistinct.

With the development of digital television and improved picture quality, 55-inch televisions have become the most popular. It is ideal for a hall in a standard apartment. The length and width allow you to set it correctly and watch the gears with comfort. A 55 ″ flat monitor does not require much space. Most models simply hang on the wall and watch analog and digital TV broadcasts.

Marketers argue that it is easier to characterize equipment with one number in inches than two or more. Manufacturers of various products indicate the size of the monitor. the diagonal and the width of the frame around it.

The length and width of the TV screen have a standard aspect ratio of 16: 9. The diagonal in inches represents the hypotenuse of a right triangle. You can find out what the height and width of the TV monitor is using the Pythagorean formula through the square root.

In order not to make complex calculations in inches, you should use the already calculated ratio of the dimensions of the diagonal and the sides:

  • height. 1.14;
  • width. 2.04.

The procedure is not complicated at all. When buying, the diagonal on the model’s marking in inches first looks. Then it is calculated on a calculator by multiplying by 2.54 and it is determined how many centimeters the screen will be. Then it is divided by the coefficient of the desired parameter. A calculator in your mobile phone is enough for this operation.

The TV is slightly larger. A frame is visible around the monitor. It does not exceed 5 centimeters or 2 inches in each direction in modern models. The dimensions of the case should be added to the data obtained during the calculations. The dimensions of the equipment are of great importance when placing the TV in a niche of furniture or a wall.

What is determined diagonally

You can comfortably watch programs only if the TV is installed correctly. The distance from the screen to the eyes should be 3-4 diagonals. First, it is determined how many cm or inches is the distance from one corner of the screen to another. Then the distance to the sofa or chair is calculated.

Some types of TV with high resolution allow you to see the picture well at close range. TV distance can be reduced to 2.2 meters.

The second factor for a clear picture and free viewing is the height of the monitor. Ergonomics dictates that the center of the screen should be at or below eye level within a 10 degree angle from the horizontal. If family members are of different heights, the TV is installed 50–70 cm above the floor. For a 139.7 cm screen, the optimal bottom edge to the floor is 55 centimeters.
