Monitor diagonal in cm and inches: table of values

It is customary for manufacturers of televisions and computer monitors to produce devices with certain standard aspect ratios. Of the most common formats:

• 16: 9, the name of the format is HD 720p, or widescreen;
• 5: 4, SXGA;
• 8: 5, WXGA + and the like.

How the screen size depends on the diagonal in cm. and inches

The first ratio on the list is the most common. But it has recently been giving way to 16:10. The geometric size of the screen in this case depends on the length of the diagonal in inches or centimeters, as in an ordinary triangle. In trigonometry, such sizes are usually determined using sines and cosines.

It should be noted that the most favorable format for viewers, according to many experts, is a 16: 9 ratio. There are several reasons for this. This ratio is convenient for perception by the human eye. Not the least role is played by the fact that almost all of the popular video products are made for such a format. On TVs and monitors with other aspect ratios, viewing it is not very convenient.
