Steps to Measure Laptop Size [100% Accurate]

Well, before we get started, it’s important to establish a few fundamental concepts. Please let us know what all of the fundamental concepts are prior to moving on to the measurements.

Things to know before taking the measurement

First and foremost, the screen size has nothing to do with the overall size of the laptop. Both of them are distinct in that they do not contain the bezel portion of the laptop screen. Second, when purchasing a laptop bag, it is always a good idea to add a few inches to the actual measurement to account for error.

In addition, a measuring tape or a large ruler will be required to determine the appropriate size. Keep in mind that this is not just to measure the screen size, but rather the overall laptop size, which includes everything. We have a fantastic guide here that is focused solely on measuring the screen size and offering some more helpful information.

Inches are the standard measuring unit that is utilized at the majority of locations or sites. However, if you have a different measurement in mind, you can convert it once the work is completed. We can now proceed to measuring the laptop’s dimensions, which comprise its height, width, depth, and diagonal. These dimensions are as follows:

Step 1: Measuring Diagonally

The first and most fundamental measurement that everyone should be aware of is how to precisely measure the size of a laptop or even the screen size. The diagonal measure is a highly accurate measure of distance. To be honest, the process isn’t difficult, but it is necessary to grasp what needs to be accomplished.

We will be measuring with an Apple MacBook in this instance. The methods, on the other hand, are applicable to any brand of laptop, including those from HP, DELL, Lenovo, ASUS, Acer, and even MSI. As a result, you must now close the laptop screen in order to improve accuracy.

Placing the measuring tape at the bottom left corner of the laptop and stretching it all the way to the top right corner is recommended. This is the approximate size of your laptop computer. You have the option of measuring in inches or centimeters. Alternatively, you can convert to any unit you choose. A standard MacBook Air is approximately 15 inches in height and width or higher.

Step 2: Measuring Height

Following that, we’ll take a measurement of the laptop’s height. Given that you are measuring a live model, distinguishing between the height and width may prove tricky. Make certain that you adhere to the instructions.

Start by putting the measuring tape on the laptop’s top-middle and stretching it all the way to the bottom of the laptop. If you have a laptop or MacBook, this will be the height of your device. Now, if you are shopping for a bag, make sure to increase the measurement by a fraction of an inch or two each time.

Step 3: Measuring Width

We will now measure the breadth of the laptop to ensure that we have a precise understanding of its dimensions. In order to precisely measure the width of the laptop, you must position the measuring tape horizontally on the top of the laptop from left to right.

Add only a small amount of extra width to your real measurement for the bag or any other reason, or it will seem awkward and be too bulky to be carried around comfortably.

Step 4: Measuring Depth

Last but not least, you will need to determine the depth of the laptop. Consider the sides of the laptops and position the measuring tape vertically on the sides of the laptops to determine the depth of the laptop. To gain a better understanding, simply refer to the graphic below, which depicts the same movement as well as how the measurement has been carried out.

It will also provide you with a sense of how slim or hefty your laptop is for any other function you may use it for in the future.

How to know which laptop Bag or Skin to choose based on Size?

Many customers make the extremely common error of selecting a bag or a laptop skin based on the size of the screen that is advertised everywhere when they are shopping. Instead, it should be based on the actual size of the laptop, which should take into account the borders and bezels as well as the screen.

If you have followed the steps outlined above to determine the size of your laptop, you should now be aware of the dimensions of your laptop, which include its height, width, depth, and diagonal. So, these are pretty much sufficient criteria for selecting a laptop bag depending on its size. If the precise measurement is not known, then design and quality become secondary considerations.

A similar approach can be used to select the appropriate Laptop skin for your machine based on its measurements. Because you intend to use it on the panel, you will need to either hunt for bespoke stickers on which you can write measurements or acquire skins that are the exact size you need to fit the panel. Alternatively, you will have to cut it when it arrives based on the measurements provided.

All of this may appear to be a touch excessive, but it isn’t at all. The idea behind finding you the appropriate bag and skin for your laptop is really simple; otherwise, you might order or buy the wrong one based solely on the size of your laptop’s screen.



Lastly, there are several frequently asked questions that users have been submitting for quite some time now, including how to measure a laptop’s size and other inquiries pertaining to this topic.

How to know the screen size of a laptop without measuring?

This has long been a standard question for anyone who does not want to go to the trouble of measuring the size of a laptop computer system. Fortunately, you can find the screen size of your laptop on the website where you purchased it or on the interior of the screen itself. Additionally, a quick Google search with the model of your laptop will assist you in determining the appropriate size, and you will not be required to measure.

There are several basic screen sizes available, including 11, 13, 15, and 17 inches, each of which has multiple versions within the same size. Now, the laptop sizes are also in between these ranges, or even higher for a laptop with a 17-inch display screen.

How to measure the screen size of a laptop?

You may use the same approach that we used to measure the diagonal dimension of a laptop to determine the screen size of a laptop as well. Avoid making the mistake of measuring it horizontally, since this will result in an incorrect measurement. In order to obtain accurate measurements, simply take the measuring tape or perhaps a ruler and arrange it along the sides of the computer diagonally.

How can I measure my Laptop in cm?

In most cases, computers have been offered with the basic screen size rather than the laptop size in inches as units of measurement. In order to measure directly in centimeters, you can either use a scale or a measuring tape. If you do not have such items and merely want the measurement in centimeters rather than inches, you can use the following formula. You will need to alter it in order to make it more convenient for you. For example, if one inch equals 2.54 centimeters and you had a laptop with a screen size of 15 inches, the size in another unit would be 15″ x 2.54 centimeters = 38.1 centimeters. This refers to the overall size of your computer, rather than the screen size in particular.
