How to recognize the diagonal of a laptop and what you need for this

The question about the diagonal of the laptop screen is controversial. Many manufacturers indicate not the actual size, but a rounded number of inches. Therefore, the laptop's passport here does not really help. Now we will try to describe several ways that will help us understand how to recognize the diagonal of a laptop (in real terms). It is worth considering that the actual number of inches can be very different from the stated number.

Most manufacturers tend to round the diagonals in a larger direction. But some still honestly inform users about the size of the screen. The only trouble is that there are very few such companies. Well, let's get to the real screen size.

If accuracy is not needed

If you are not interested in the exact size of the screen, you can refer to the documentation of your mobile PC. The diagonal will be indicated in the technical specifications. Some manufacturers supply the enclosures of their devices with special labels describing the main technical characteristics. There, too, can be specified the diagonal of the screen. If not, refer to the instruction manual and look for a section with characteristics in it.

Most users have enough generalized information about the screen diagonal. However, some notebook owners want to know more. For example, the general inscription "17 inches" does not suit them. And this is correct, since there can be as less, and more than the declared figure. Now let's move on to how to recognize the diagonal of a laptop with simple measurements.

Using the ruler

Since in our country the metric system of measurement is used (meters, centimeters, millimeters), and the sizes of laptop screens in inches, it is necessary not only to measure the diagonal, but also to calculate the required number of inches using a simple formula.

Measurement of the screen should be carried out from angle to corner on an inclined line. That is, the diagonal is the line between the two most distant corners of the screen. The main thing is not to mix. In the measurement procedure itself, there is nothing complicated. And you will see this now.

So, we apply the ruler to the screen and start measuring the visible part of the screen. Then the resulting number should be divided by 2.54, in order to convert centimeters to inches. Now you will get the real screen size. For example, if you got 43.18 in centimeters, then by simple division we calculate that the real diagonal of the screen is 17 inches. Further in the same spirit.

Search engines

The question of how to recognize the diagonal of a laptop has one more answer. You can refer to the rich reference material on the Internet. It is enough to drive a laptop model into the search string "Yandex", and the system will give you a huge number of results with a detailed description of the technical specifications. However, it is very difficult to know the real size of the screen in this way. In this way, you can get only general information. But if you stumble upon a site for a detailed study of laptops, it is possible that local "experts" have investigated your model along and across and provide reliable data.

However, it is not necessary to rely particularly on the data of the Network. Not all sites verify the veracity of the information provided. To obtain the most accurate data, it is better to use the manufacturer's official website directly. It is there that you can find the most accurate and complete information about your laptop and its screen.

What is the exact screen size for?

First of all, you need to know the real size in case of failure of the laptop display. Categorically, it is not recommended to be guided by general data to replace this element. There are cases when users, guided by the inscriptions on the box, ordered a new matrix, but it did not fit, because it was more or less than necessary. Here accuracy is important, and general information does not fit.

Some need to know the real dimensions of pure curiosity. It is always interesting to know how many unscrupulous manufacturers are and how many inches they have deceived users. Although this happens quite rarely.

Conclusion

Now the question of how to learn the diagonal of the laptop, disappears. And if the screen of your device fails, you can easily measure the old one and order a new one. Nothing complicated in this. And for self-study it is useful to know how inches are considered in diagonals.
