How To Check Laptop Screen Size? – Step By Step Guides 2021

This can be a question pooping-up in the owner’s mind, sometimes, especially when they are not aware of the exact specifications of their PC, right? Also, the laptop’s screen size is important to know when the owner has to buy a laptop bag or they need to fix or replace the screen of the laptop. So, there could be many reasons that the owners will be interested to know the exact screen size.

Are you also looking to know the screen size of your laptop? Well, you are in right place. For finding the size of a laptop computer, there are some simple methods. In this post, these are further discussed. Just stick with the articl till the end to figure out the best method to check the laptop screen size.



The traditional method of measuring the screen size is by using a measuring tape. From the top left corner to the bottom right of your screen, use your measuring tape. Or from the upper right corner to the bottom left corner of your screen. Measure the screen only; don’t include the monitor frame or the “bezel.”

PRO TIP: As the traditional measuring unit for laptop screen sizes, the hardware industry uses inches. So, when you do your screen measurement, make sure you use this unit instead of the other.


You might not have a measuring instrument or ruler. So, here are some tricks for figuring out the size of your laptop screen without measuring it. The following are the other five key ways how to check laptop screen size.


By comparing it with regular A4 paper (corresponding to 13 inches), you can measure the screen size of a laptop, and you can also measure the screen size of a laptop without using a tape measure. They would be 11.6, 13.3, 14.1, 15.4, 17.3-inch laptops, depending on whether the screen size is small or wide relative to the paper.

Rulers are a great option because you can convert and calibrate different measurements as required, or use them to measure various screen areas, as well as images and other objects.

By measuring the screen with the aid of a measuring tape, the size of a laptop screen can easily be found. Make sure that you placed the measured side of the measuring tape on the diagonally opposite corners of your laptop during the screen measurement. Check if the tape is clean, as it can make your computer dirty, as a precautionary measure.

2-Model Number Usage

A convenient way to find a laptop’s screen size without taking a measurement is to verify the model specifications of the laptop. You can find these details on the case from which you bought it (in its user manual) or by looking at the cover on the laptop’s bottom to see if it is present. A model number’s requirements should explicitly state the size of the screen or at least the model.

Searches can display model specifications instead of screen size in some instances. Use this model to browse online for your screen size. It might not be entirely correct if it is general knowledge. A website unique to you will be available several times, and you can inquire for sizes from their customer service.

3-Using the Web or an Application

Technology has revolutionized the digital world. Online Rulers are software on your laptop or desktop screen that helps you calculate elements. You will need to download the software and install it, but compared to looking for lines of code and requirements it will save you tonnes of time. If you need to measure the bezel field, this will not work, though. Some apps enable you to enter the current resolution of the monitor and a few other screen requirements, so apps do the rest for you. Most online rulers, however, allow you to simply drag the edge of the ruler shown from one corner to the other to get the length of your screen. Digital rulers are a great choice because you can convert and calibrate different measurements as required, and you can also use them to measure various areas of your screen as well as images and other objects. Some fantastic websites will allow you to calculate the screen size of your laptop.

4-Viewing the Laptop Backside

Rotate the back of the laptop and look for a label that includes the model of the laptop and some significant specifications for the laptop. It also includes the display’s scale.

The screen size is also indicated on certain laptops by a number in its upper-right corner. H243HX, for instance, means that the screen size is 24 inches.

5- Using laptop specifications

Checking the model dimensions of your laptop is an easy way to find your laptop’s screen size without measuring it. These specifications will either be available from the user manual on the casing you purchased it in, or you can check the cover on the bottom of your laptop to see if they are there. The requirements should explicitly define the size of the screen or at least the model number.

If you are unable to access the specifications from the packaging or cover of the laptop, a simple search for the model details settings on your device should work. You will find the screen size under the properties of the laptop, normally in the monitor settings folder. If not, try the tab for the advanced monitor settings. If you don’t understand what they represent, be careful not to change them. In certain situations, the search could disclose the requirements of the model and not the screen size. To search online for the size of your screen, use this model number. If it is general, this may not be absolutely precise knowledge. There would be a website specifically for your brand several times, and you can ask about the measurements from their customer service.

Another choice would be to look for similar devices to yours online and try to estimate your screen size. Search for the nearest make and/or model that comes to yours. This may not be true but may serve the function for which you need the measurements, such as in the case of purchasing a laptop bag. You will need more precise measurements if you need the dimensions for purposes like buying screen guards or connecting to other screening devices. For the tech-savvy ones, a more suitable quest will be for a command line code that will generate the specifications. This does not need to be too hard, though, as you copy the file depending on your laptop model, paste it into your command prompt (you can scan for this program on your computer), and run the code. Depending on whether or not the drivers are up to date, this code can include precise measurements. You will need to know how these findings can be read.


In sizes and ratios, laptop displays differ. When you purchase a laptop, one of the most important components to review is the screen. The distinction between Core i5 and Core i7 CPUs might not be noted by people who do not need to perform many high-end tasks, but even the least tech-savvy individuals would like beautiful displays. So, you need to pick the best screen, whether you’re choosing between competing models or choosing the laptop configuration you want. You will look at it all day, after all. If you want to know what are the screen sizes that laptops come in the market then read till the end.
