How To Measure Laptop Screen Size: Step By Step Guide (2022)

Knowing how to measure a laptop screen before purchasing one is essential because there are so many various screens and sizes on the market that determining which one is suitable for you can be difficult. So, how to measure laptop screen size? In this post, MedCPU will put together this fast and easy guide to measuring screen sizes for you.

How are laptop displays measured?

Your laptop’s inch size indicates the diagonal measurement of the screen from edge to edge. This size does not include the ‘bezel’ (the housing that surrounds the screen), which can easily add an inch to the overall size. Place a measuring tape in the bottom left corner of the screen and measure it up to the top right corner, then convert it to inches. This determines the size of your computer screen.

Step by step to measure laptop size

Here are the step-by-step instructions.

Purchase a standard tape measure

Getting a standard tape measure is the best approach to measure a laptop screen. The conventional tape measure will almost certainly have inch units on one side. But if you do not have inch units, do not worry; you can always convert your unit to inches.

Determine your starting point

Before you measure the size of your laptop screen, there are two things you must realize. The first point to mention is that displays are always measured diagonally. And the second is where a lot of people go wrong.

The measuring point is not the top corner of your screen, but rather the point at where the real screen begins. As a result, you will need to turn on your laptop to see where your screen begins and finishes.

We strongly advise you to begin with the top left display corner and end with the diagonal corner in the bottom right display corner.

Make a note of your measurement

If you have successfully measured the size of your screen, make a note of it so you do not forget. You will not need to convert anything if you measured in inches. However, if you have measured in a different unit, it is ideal if you convert the measurement to inches.

Converting centimeters to inches

It is really easy to convert it to inches. 1 inch = 2.54 CM

For example,

If you measure your screen at 39 cm, you must divide it by 2.54 cm to get inches.

39 CM (measured screen size) :2.54 CM (1 inch is 2.54 CM) = 15.4 inches

What are the typical laptop sizes?

Although there are no global standards for laptop physical configuration or screen size, certain models are more consistent than others. The fact that two laptops have the same diagonal size does not imply that they have the same horizontal and vertical dimensions.

The majority of laptop screens range from 13 to 15 inches in size. Compact notebook sizes range from 11 to 13 inches at the low end. The largest laptop has a screen size of 17.3 inches.

How do you determine your laptop’s screen size without measuring it?

Comparing it to a standardized A4 paper

The size of a laptop screen can also be determined without the use of a measuring tape by comparing it to a standardized A4 paper (which corresponds to 13′′). It will be either 11.6, 13.3, 14.1, 15.4, or 17.3 inch laptop depending on how little or large the screen size is in comparison to the paper.

Know the model number

Every laptop comes with its own model number. You may utilize the model number to find out important information about the laptop, such as the screen size. Laptop model numbers typically begin with one or two letters before the number one.

The Acer laptop with model number S291HL, for example, features a 20-inch screen. The figure “20” that appeared following “S” immediately indicated the screen’s size.
