How do I know the size in inches or pixels of my laptop screen on Windows or Mac?

Laptops have become a great tool and ally when you need to work outside of your home or at work due to their small size. But how big or small is he? Today we are going to you get to know the size in inches or pixels of my laptop screen in Windows or Poppy.

There are many occasions when we need to transport our computer from one place to another, but in order to do this we need to keep it in a briefcase or briefcase to protect it from bumps and prevent it from breaking.

The problem arises when we don't know the size of our laptop and end up buying something too big or too small that we don't use to protect it.

In addition, knowing the screen size of a laptop can help you know if it will be useful for the work you want to do there . This without neglecting, knowing the technical specifications and the tools available to you.

How to find out how many inches my laptop screen is step by step

Before you start, be aware that these types of computers have screens ranging from 10 inches or 25,4 cm to 18 inches, or 46 cm, although this will depend on the model and brand of it.

To begin with, you must have a metric c inta and a unit converter or a calculator to manually change the unit by multiplying 2,54 by the number of centimeters in your laptop.

Don't forget to turn off your laptop and open it to an angle of 90 ° (ninety degrees) so that it can be done easily and without problem.

We recommend that you use a tape measure to measure it because they are soft and smooth, so you wouldn't risk damaging it if you do it with something more rigid.

You need to find a point to start measuring. Note that it is calculated by measuring diagonally . We therefore recommend that you start in the lower or upper right or left corner of the screen.

Now extend the tape measure from the starting point to its opposite corner. Here you need to measure the screen avoiding doing it from the frame of it as it doesn't count as inches.

Finally, you need to do the unitary step as we mentioned at the beginning:

laptop cm x 2,54 = inches of your screen

When you have done that, you will be able to know the number of inches of your laptop.

How to calculate the pixel density of my Windows or Mac laptop screen

The first thing to do is to know the graphic density or PPi . It is directly related to the size of your computer visor, because the larger the screen, the better the graphics resolution you will have.

To do this, first enter the system configuration. From there, enter the screen option.

In this section, look for advanced settings of the screen. In the section Resolution of the screen, click the arrow pointing down to select Maximum supported by the equipment.

It will give you the following information:

N ° of width X N ° of height of the screen.

With this data, we will do some calculations. We recommend that you use a calculator for this, because no matter how proficient you are in math, these are big numbers.

You have to add the two numbers not without first raising them to the second power. That is to say

(Width ²) + (Height ²) = value obtained

Then you need to extract the square root of this sum. Save this result for later:

√ value obtained = value 2

Now you need to take a tape measure and measure the screen size of your Mac or Windows laptop diagonally as we did in the previous section. But you don't have to change it to inches, you will need this number in centimeters .

Finally, divide the value obtained after taking the square root of the sum of the pixels and by the number of centimeters in the previous paragraph:

laptop cm / value 2

The result will be the pixel density of your laptop.

It is also helpful that you know the refresh rate of a monitor to know how the fluidity of the image is
