However, if you are interested in knowing the size of a monitor, you can do a Google search to find out the specifics.

Just open them and access the tabs Specifications, Data o Technical features to check the dimensions on the screen that you will find expressed in inches (″) or centimeters (cm).
If the search on the popular search engine does not have the desired results, you can always resort to "traditional methods". You must know, in fact, that the dimensions of the screens are usually obtained by measuring the diagonal (i.e. the distance between the opposite corners) of the latter in centimeters (cm) and dividing the result obtained by 2,54 (since 1 inch equals 2,54 centimeters).
Furthermore, you can also get the diagonal measurement by applying the Pythagorean theorem: the measurement of the diagonal is equal to the square root of the sum of the length and height of the monitor, both squared. For example, if the length of a monitor is 75cm and its height 42cm, the diagonal will be 85,95cm.
