Things to know before measuring your laptop

First of all, before you can measure your laptop, you will have a measuring tape or ruler. Secondly, after all, your computer.

It doesn’t matter which one you choose, but all my measurements are in inches for this tutorial.


The scale issue in your measuring tape is 1: 8. For instance:

1.0″, 1.1″, 1.2″, 1.3″, 1.4″, 1.5″, 1.6″, 1.7″, 2.0″, 2.1″,……

How to Measure Laptop Size Step by Step Guide

Step 1: Get a standard tape measure.

The most outstanding technique to measure a computer display screen is to get a standard tape measure. Probably, standard tape measurements will likely come with inch units on one side. But if you don’t have inch units, no need to s worry because you can always convert your unit to inches.

Step 2: Find your starting point.

You need to understand the two most important things before actually measuring the size of your laptops screen.

The first thing is that screens are always measured individually. And the second is where a lot of people think it’s wrong.

The measurement point is not the top corner of your screen, yet the actual screen starts.

So, it would help if you turned on your laptop to find out where your screen starts and ends.

We strongly recommend using the bottom left display corner as the starting point and the endpoint as the diagonal corner in the bottom right display corner.

Step 3: Write down your measurements

When you have successfully measured your screen size, please write it down not to forget it. If you have measured in inches, you will not need to make any changes.

But if you have measured another unit, it would be better to convert the unit to inches.

You may be wondering why this is necessary?

One of the standards of the screen industry is to label the size of the screen in inches. Whether it’s a laptops screen, a desktop computer screen, or television – the unit will be inches.

Step 4: Convert centimeters to inches

If you’ve measured your laptop screen in centimeters, it’s effortless to convert it to inches.

1 inch = 2.54 cm

For example – if you get your screen to get 34 cm, scale inches. You have to divide it by 2.54 CM.

34 cm (screen size measured): 2.54 cm (1 inch is 2.54 cm) = 13.3 inches

Measurement of body thickness

Once you know your screen’s size, it is helpful to know your body’s height, which is also called the thickness of the laptop body.

It is helpful to know the body’s thickness, especially when you are buying a laptop case or bag. You can find the right laptop size on rare occasions to find out that your laptop doesn’t fit easily in a laptop bag.

To measure your laptop’s body thickness, retrieve your standard measuring tape. Turn off your laptop, and measure the laptop body from bottom to top where the screen ends.

But make sure you include the screen in the measurement process. If you measure only the bottom of your laptop, you will not find the right thickness.

How do you measure laptop screen size?

Use your measuring tape from the top left corner of your screen to the bottom right. Or if you prefer the top right corner of your screen. Screen measurement only; Do not include monitor frames or “bezels.”

The hardware industry uses inches as a standard unit of measurement for the size of a laptop screen. So, when you measure your screen, be sure to use this unit instead.

How to Use the Measure App in iOS

If you have got an iPhone, you in all probability do not want a ruler to measure a laptop computer. With iOS 12, a new app comes built-in on iOS devices called Major.

If you haven’t updated your phone in a long time, please update it first to use this app.

Note: If you are utilizing an Android cellphone, you may obtain Google Play’s measurement app on your cellphone.

The step-by-step method of measuring through the app is:

Step 1: Launch the measurement app on your phone.

Step 2: Move your phone around until you see this screen on your screen. You’ll see some instructions appear on your screen telling you to move your phone around so that the app can quickly scan things around you.

Step 3: Next, move your machine round to get a place to begin for what you wish to measure in the course of your display screen.

Step 4: Tap the plus signal button on the backside to add a dot. Suppose you make a mistake, faucet the Undo button within the high left nook to attempt once more.

Step 5: Next, move your iPhone upwards so that the endpoint of the line you’re measuring appears in the middle of your screen, and tap the plus icon again to end the line. 

You will then see that the measurement appears along the line you have drawn. If you are trying to measure an object’s dimensions, you can create multiple line measurements simultaneously.

Step 6: Tap the measurement to see the conversion to other units of measurement. Tap Clear within the high right nook to clear and resume all your measurements.

Keep in mind that measuring with a measurement app may not always be accurate. Therefore, measuring with a measuring tape is still best done to achieve accuracy.
