How to Find Out Your Laptop Screen Size Without Measuring

You can measure your laptop screen to get the size, but it is not advisable. Measuring your screen with a tape on any other measurement material might cause your screen to develop a fault. There are several methods of how to find out your laptop screen size without measuring.

How to Find Out Your Laptop Screen Size Without Measuring

1. Use a standard object

This is one most straightforward ways to determine a laptop screen’s size without measuring. Get a standard A4 paper that is 13 inches. Now, place the paper on the laptop’s screen to see if it matches.

Use a standard object

The laptop screen will be one of these sizes, 11.6 inches, 13.3 inches, 14.1 inches, 15.4 inches, or 17.3 inches. With the paper on the screen, you can tell where the screen size falls.

2. Know the laptop model number

Every gadget comes with a model number specifically for it. This number helps people find important information about the device and applies to laptops.

There is a label pasted there on the back of the laptop. Every product manufacturer puts it for users to find useful information. The label contains other specifications of the laptop and the model number that states the size of the laptop screen.

Know the laptop model number

To figure out the laptop’s screen size, check for the number after the first letters. The model number does not always start with one letter or two. So, whatever number of letters it starts with, the first number is always the screen size after the letter.

However, it is not always accurate, but it is close to the accuracy. This is because manufacturers don’t write only the screen size number and add other numbers. So, you might misread it sometimes.

3. Use the model specification of the laptop

Another method is to check the model specification of the laptop. The model specification always has the screen size on it. It will have the model number if it doesn’t, and this is a quick way of checking, as we mentioned earlier.

The model specification can be behind the laptop, on the carton, or in the user’s manual. You can also follow these simple steps to find it on the laptop.

  • Open and boot your laptop.
  • Go to the ‘Settings’ option on the laptop
  • Open ‘System’
  • Click on ‘Display’
  • When it opens, click on ‘Advanced Display Settings.’ When it opens, you will see the information about the laptop screen you want.

4. Use software or search online

With the technological evolution, some software can tell you the specification of your laptop. It will also tell you the size of the screen. All you need to do is download and install it on your laptop.

Use software or search online

Not all software will give you the detail you require. For some, you have to provide the display resolution and a few other specifications to get the screen size. Some will give you the full-screen specifications plus the screen size without any information from you.

Some apps use rulers. When you open such apps, drag the ruler from one end of the screen to the other to get your screen size. You can search online to get the screen size of your laptop. Most websites that offer this service require your laptop’s model, resolution, and maybe other specifications. The good news is that they produce the result in a few seconds.

5. Inspect the laptop’s backside

On the back of your laptop, a label has the laptop’s specifications. Most times, it has the screen size of the laptop on it. You can use the model number to determine the laptop’s screen size when it doesn’t.

Inspect the laptop’s backside

The screen size is always the number after the first letters. So, although it does not always give an accurate figure, it provides something close to the precise figure.

6. Check the manual for the laptop screen size

Almost every device has a manual for users. Manufacturers know some customers are first, and they will misuse the product if not properly guided. Even regular users might still want clarifications on some aspects they might have forgotten. So, the manual is essential.

It is always in the product packaging, and it has specifications of the product in it. So, check for your laptop manual and go through it. Under the specifications, you will find the size of your laptop’s screen.

7. Check for the laptop online

The internet has made things easier for people. You can go online and search for anything you want, and you will see it or something close to it. So, on that same note, go online and search for the specification of your laptop with the model, brand, and probably model number.

This is a straightforward process. Sometimes, you can go straight to searching the screen size of your laptop.

What Are the Things to Consider for a Quality Laptop Screen?

To get a good laptop, consider these laptop screen features.

Screen Resolution

Screen resolution is the number of pixels in a laptop display area. For example, some laptops have 1920 x 1080 HD resolution, and others have 1024 x 720 High Definition (HD) resolution. Then there are the ones with the Full High Definition (FHD), 4K, 1400, and more that are more understandable and regular.

What Are the Things to Consider for a Quality Laptop Screen

Mainly, the laptop’s price determines the screen resolution of the laptop. A good screen resolution makes the laptop screen display things faster, clearer, and brighter. So, when buying a laptop, consider the screen resolution as a low one that can frustrate your usage.


A bright screen is something everyone wants on their devices for gaming, editing, watching movies, and other things we do with our devices. Nit is a component used to measure the level of brightness of your laptop screen.

Devices like laptops, smartphones, and other mobile devices only have one brightness measuring tool, which is the nit. For example, most laptops come with 200 to 300 nit brightness settings. However, Macs mostly have 540 units.

Contrast ratio

They also call it the display aspect ratio. It makes the difference between bright and dark colours on a device screen. When the contrast ratio is highest, you see an accurate display on your laptop screen. But when it is low, part of the screen becomes darker than others, so the image display is inaccurate.

Refresh rates

The laptop’s refresh rate is the frequency of display per second to switch the image. You can measure the refresh rate in Hz. People use average refresh rates of 60Hz and 144Hz, depending on what they want it for.

For gaming, you need a higher refresh rate ranging from 240Hz to 360Hz for a seamless gaming experience. But for things as simple as web browsing and other light activities, 60Hz to 144Hz is good enough.

Black and White Accuracy

Another way to measure screen excellence is the black and white accuracy, also called the black surface. This aspect of the device is like the contrast rate. It specializes in black displays on different screens. It determines how the screen shows the black with a calculative figure.

The smaller the figure, the better the black surface, and the higher the figure, the lower the black surface. This feature also measures white surface levels. The higher the figure, the better the white surface representation and vice versa. Its highest at RGB is 255; then, the screen will display an accurate white surface.
