Measure Laptop Screen Size With Measuring Tape:

There are different screen sizes for laptops. Correct measurement is also helpful in determining the size of a screen.

Using a measuring tape or a ruler is the easiest method to measure the screen size of a laptop. 

Users of laptops will find the screen size on top of the laptop because some manufacturers display this information on a sticker. In case you can’t find it anywhere, you can use the measuring tape and ruler to measure the size of your screen. 

Use a measuring tape of sufficient length:

  1. Draw a diagonal from the top-left corner to the opposite bottom-right. If you start from the top-right corner, draw it straight down to the bottom-left corner.

Check the specs on the backside of the laptop:

The laptop screen size can be found on the back of the laptop. In general, you will find your laptop’s details at the back of the machine, such as the serial number, the product number, the RAM, and the screen size too. 

In some cases, if you cannot find details on the backside of your machine, then you can check the right side of your laptop’s screen

Because, in some laptops, the screen size is indicated on the right side of the screen so that a user can find out the size of their laptop’s screen simply by looking at it.

  1. Find the Your Laptop’s Screen Size From Official Website:

Some websites demand serial numbers to check your laptop’s model so for that;

How To Measure Monitor Size With Simple Math:

It’s true! You heard me right! You can even measure the size of your laptop’s screen using a mathematical formula

When I discovered this method, I was also shocked. I couldn’t resist sharing it with you as it’s one of the interesting methods that I have never seen before

The Pythagorean Theorem :

Pythagorean theorem is a method for measuring a laptop screen size. According to this rule, the square of the hypotenuse side of a right-angled triangle is the same as the sum of the squares of the other two sides. 

On a laptop screen, the hypotenuse is the diagonal measurement. 

To calculate the screen’s width and height, square the width and height of the screen and add the two numbers. Take the square root of this sum to determine the diagonal measurement and screen size. 

For instance, a Dell XPS 13 has a screen size of 11.57 inches by 6.51 inches. 

Add the two numbers together (133.8+42.38 =176.18). After multiplying the height by itself, you get 42.38. Add these two numbers together (133.8 + 42.38 = 176.18). Calculate the square root of the sum (√176.18 = 13.27).

Hurrah you have found the answer 13:27 inches.

Hahahaha but trust me, it’s not our style to measure screen size using this Pythagorean theorem

A Final Conclusion:

These are some simple methods for measuring the screen size of a laptop. It is generally a good idea to understand your laptop’s screen size.

In my opinion, however, I personally prefer to use an online method to determine the screen size of a laptop and its other details.
