Are you intending to sell your laptop and have no idea about its screen size? Or you have just spent handsome money buying a brand new laptop, and now wondering whether the screen size of your laptop is exactly what was mentioned in the specs or not. Let me just tell you the simplest method to do so. 

You can simply measure the screen size of the laptop using a measuring tape. Just open your laptop and place one end of measuring tape at the top corner of the screen and bring it down (diagonally) to the lower corner of the screen. That’s it, now you check the length on the tape.

Measuring the laptop’s screen size is not a difficult task. You can also check the screen size through the model number too. So here in this article, I will guide you about everything that you need to know about laptops whether it is for working or entertainment purposes. Let’s Read!

Things To Consider While Buying A Laptop With A Big Display

Before starting with the methods to measure the screen size, I will enlist some of the major things you must consider before buying a laptop. A laptop with a bigger screen is not always better than the smaller one. So make sure to keep the following factors in mind while buying a laptop.

  1. Graphics

Graphics is the major factor that you must consider while buying a laptop. A laptop with a big display is not always necessary to provide a better display. The quality of the display depends upon the resolution which a screen can offer, not on the size of the screen.

A laptop with an FHD display will provide a better and clearer display than a laptop with an HD display, irrespective of the display size. So before buying a laptop, you must check the graphics or simple resolution offered by that laptop.

  1. Portability

Portability is another major problem with laptops having a bigger display. The laptops having a bigger display size are also bigger and heavier than other laptops, making them hard to carry from place to place. If you are a person who has to travel a lot, then laptops with bigger display sizes might not suit you.

All You Need To Know About Screen Size (What’s The Right Screen Size)

To tell the best screen size of a laptop for a single person is not possible as it is purely based on personal preferences. However, depending upon the portability and usage, I can suggest to you the best screen size which you may also find good.

If you have to take your laptop with you every time you go out, the screen size between 11- 15 inches is the best range. This size makes the laptop much easier to carry around.

What if you use a laptop for gaming or tasks like video editing, and you do not travel with your laptop very often? Then the bigger display size can also suit you. The display size range between 15-17 inches will be most suitable for such use.

Standard Screen Sizes

Laptops particularly do not have a standard screen size, they come in various sizes, but the range of the display is usually the same for every laptop. The laptop’s display size range is between 11 inches to 17.3 inches. All the laptop’s displays are generally under this size range. Laptops’ standard screen sizes are 13.3 inches, 15.6 inches, and 17.3 inches.

Two Super Easy Methods To Measure Laptop’s Screen

Measuring a laptop’s screen is a simple task that can be done easily without spending any money. Every person can measure the laptop’s screen easily. The methods which a person could use to measure the laptop’s screen size are as follows.

  1. Using Model Number

The easiest method to measure the laptop’s screen size is definitely through the model number. To measure the display size through model number, follow the following steps.

  • First, look for the model number of your laptop.
  • Once you find your model number, open your internet browser.
  • Now type the model number of your laptop and write the screen size in front of it.
  • Google will automatically tell you the screen size of your laptop.

Note if you cannot find the model number of your laptop, you can also search the internet with your laptop’s specs and the name of the company to which your laptop belongs and type screen size in front of it.

  1. Using Measuring Tape

What if you want to check whether the display size on the internet is accurate or not? You can also use a measuring tape for this purpose. To measure the laptop’s screen size using a measuring tape, follow the following steps.

  • Get the measuring tape.
  • Open your laptop.
  • Now place one end of the measuring tape at the top corner of the laptop’s screen.
  • Now measure diagonally from one end to the other.
  • The length is the size of your laptop’s display.
Note This method is not very accurate; the chances of error are much more, but it will give you a rough idea about the size of your laptop’s display.


A laptop’s bigger display makes it much more attractive than smaller laptops, but it is also more expensive. So if you are going to buy a laptop and are having trouble with what screen size you should choose or what is the laptop’s screen size? Then this article will help you. The best method to measure the screen size is surely through the model number as it is more accurate.

    A laptop with a diagonal of 15.6 inches must have a length of around 36 cm (14.1 inches) and a height of around 21 cm (8.26 inches).

  2. What is the difference between 14 inches and a 15.6 inches laptop?

    The main difference is size and portability, a 14 inches laptop is generally smaller in size and quite easy to carry which makes it ideal for those who travel a lot. While on the other hand, a 15.6 inches laptop is bigger which is why it’s good for those who love bigger displays.
