What Is A Laptop’s Screen Size?

We use the size of a laptop to describe how big the gadget is. However, many users are still confused about this term. 

Size vs. Width

Many users mistakenly believe that the display dimension listed in the specifications is the width. This idea is not true. Two computers with the same display size but differing widths are possible.

The screen size is the diagonal length of the monitor from the top left corner to the lower right corner or vice versa. The length doesn’t include the bezel.

The bezel is the rim that surrounds the monitor and does not qualify as part of the monitor.

Size vs. Resolution

The actual dimension of the monitor in inches is the size. On the other hand, screen resolution refers to the number of pixels on display. 

For example, a 5-inch iPhone display screen can have a resolution of 320×480 pixels.

Keep in mind that even displays with the same dimensions might work with different resolutions. 

When creating mobile-friendly layouts, developers utilize viewpoints to make sure that the app looks the same on all platforms.

How To Measure Laptop Screen Size? 

Screen size is a diagonal distance between its corners. This video shows you the full process of measuring laptop screen. 

Here are the detailed instructions.

Don’t worry if you don’t have inch measurements. You may always convert your measurement to inches if needed.

Step 2: Find the measuring point

You need to measure all monitors diagonally. The measuring point is the place where the real display begins. Many people make the same mistake when using the top corner of the monitor as their measuring point. 

You’ll need to switch on your machine to see where your display begins and ends.

As a beginning point, we strongly advise you to start at the upper left monitor corner. The bottom right corner should be the ending point.

Step 3: Take note of the measurement

When you’ve established the size of a laptop, please take note of it. You won’t have to convert anything if you’ve recorded in inches.

However, if you have checked in different measurements, it is better to convert to inches. In the monitor sector, it is common to mark sizes in inches. 

Step 4: Convert centimeters to inches

The formula to convert centimeters to inches is quite simple: 1 inch = 2.54 centimeters.

For example, if your monitor is 35 cm, you’ll need to divide that by 2.54 to get inches: 35 / 2.54 = 13.8 (inches). 

How To Measure The Laptop Thickness? 

After you’ve determined the screen size, you’ll need to know the body height, also known as body thickness.

When buying a laptop bag, knowing the machine’s thickness is quite helpful. You may purchase the right size of a laptop in rare situations only to discover that your machine does not readily fit into the laptop bag.

First, retrieve a measurement tape to determine about the thickness of the computer’s chassis. 

Then, close the machine and measure from the top to the bottom of the monitor.

However, be sure to include the monitor in the measurement. You won’t have the proper thickness if you simply measure the bottom half of your machine.

How To Identify Laptop’s Screen Size Without Measuring? 

There are many ways to figure the screen sizes. If you don’t have a measuring tape, you can use these alternatives.

Model name

You need to check about model specs of your machine as a way to identify the screen dimension without having to take a measurement. 

You can find these major laptop specifications on the case you bought it in or on the cover of the machine if one is available. 

The model number’s specs show specifies the screen resolution or the variant.

For example, your Acer model name is H243HX. You will know its display is 24 inches. Often, the first numbers after the first letter indicate the size. 

In certain situations, rather than computer screen size, searches may give model characteristics. You can use this information to check the screen size on the internet. 

Maybe the basic info isn’t entirely correct. You can access the webpage and ask about sizes with its customer care staff.

Technology has transformed in the digital age. Online testers are programs that allow you to measure multiple elements of your gadget. 

You just need to install the program and set it up. Nevertheless, compared to looking for code lines and specs, it may save you lots of time.  

If you want to measure the border, though, you can’t utilize it. Some programs ask you to submit the actual laptop screen resolution and a few other display characteristics before executing the rest.

On the other hand, most online measures may enable you to simply move the border of the shown ruler from one side to the other to acquire the screen’s sizes.


Check the backside for a label that includes the laptop model and some key specifications. It also mentions the display’s size.

A figure in the upper-right corner of certain laptop models also indicates the screen size.


You may double-check the sizes by looking up the screen specifications in your handbook. The manual shows the exact sizes of laptop screens.

How To Choose The Best Laptop’s Screen Size? 

You may need a computer for specific purposes. There are a few essential factors to consider when it comes to the size of a laptop. 


What do you use the computer for? Do you need a small or large monitor?

The larger options can offer you a broad viewing angle. They will also improve your productivity. 

The large display seems to be the best for gamers. On the other hand, smaller monitors are compact. Many of them come with excellent resolution. 

Another advantage of these options is cost-saving and power-effective. 


If you are often on the go, the smaller monitor is ideal for traveling or business trips. You will find it easy to carry it along with you. 

Some users just place their laptops on a fixed spot. They like to work with large monitors due to the better experience.

The area of the workspace also influences the computer screen sizes. Some people use several displays, while others work with flexible schedules and just use their laptops as monitors.

As a result, it’s a good idea to think about your workspace before choosing the screen size you’ll require.

In a crowded environment, large screen sizes might be distracting. They lost their primary benefits in this case. 

Multimedia activities

If you use laptops to broadcast or watch videos, a larger option is advantageous. It has a broader viewing angle and more clarity, making it easier to take full advantage of broadcasting and online gaming.

Gamers and streamers might benefit significantly from buying a larger or higher definition display.

How To Choose The Right Laptop Case?

When purchasing a laptop case, the most crucial factor is fit. Your gadget should fit snugly within the bag without any strain on the zipper. 

It should also not protrude towards the four corners. If such a thing happens, the bag is too small for your machine.

In contrast, the laptops should not be movable inside the case. The spare space might result in scratches and excessive wear and tear.

In addition, a cushioned compartment is necessary. It will reduce shocks and provide some support for your device in the event of a fall. 

A cushioned base will also offer excellent protection. If you drop the bag by mistake, the device inside will not get damaged.
