Would you like to purchase a monitor, but are unsure of how to measure monitor size?
Because at that time the most important factor to consider is the size of the monitor.
This guide will teach you the right way to measure monitor size so that you can find the perfect one for your needs.
So whether you’re looking for a large monitor for gaming or a small one for work, following these steps is essential.
So, let’s get started!
Two Ways to Measure Monitor Size
Following are the two ways to measure monitor size:
1. Measure the Size of the Monitor by Using Measuring Tape
When it comes to measuring the size of your monitor, you have to take a couple of things into consideration.
The first is the width, and the second is the height. You can easily measure the width by using a measuring tape.

Make sure that the measurement should be in inches so it’ll be easy for you to determine the size accurately.
Ensure that you only measure the screen of the device itself and not the bezel or the casing that surrounds it.
Keep in mind that these are only approximate measurements. If you want to be absolutely sure of the size of your monitor, you can always consult the manufacturer’s website or manual.
2. Take Diagonal Measurements of the Monitor
An aspect ratio for a monitor is usually either a 4:3, a 5:3, a 16:9, or a 16:10 aspect ratio. You can find the aspect ratio by comparing the length and height and reducing the numbers if necessary.

- The aspect ratio is 16:10 when the length and height are 16 ins (40.6 cm) and 25 ins (25.4 cm).
- The aspect ratio of 25 inches (63.5 cm) by 15 inches (38.1 cm) is 25:15. It can be reduced to 5:3 by dividing this ratio by 5.
Using the Pythagorean theorem, determine the exact value of the diagonals of the monitor by calculating the distance between the diagonal corners.
As a result, you will be able to get the exact size of your monitor with ease.
How to Find the Size of a Curved Monitor
In order to determine the size of a curved monitor, there are a few things you’ll need to keep in mind. The first thing is the curvature of the screen will affect the measurement. Secondly, you’ll need to take into account the bezel size.

Here’s a quick rundown on how to measure your curved monitor:
Step 1: Use a tape measure to find the width of the screen.
step 2: Multiply the width by two to get the circumference.
step 3: Measure the distance from the top of the screen to the center point. This is known as the radius.
step 4: To get the size of the monitor, simply add the circumference and the radius.
Keep in mind that the size of a curved monitor can vary depending on the brand and model. However, it’s always best to check with the manufacturer before making your purchase.
Where can I Directly Find the Screen Size of My Monitor?
Here are a few ways by which you can determine the size of your monitor without measuring it.
1. Determine the Model Number
Take a look at the model number displayed on your monitor. This is usually written in the bottom right corner of the screen, or it will be printed on the box of the monitor.

Following each of the letters are the two numbers that indicate how large the monitor is in terms of inches.
2. Go Through the Manual
It is also a good idea to check the manual of your monitor, as it contains other information about the monitor as well as the size mentioned there.

3. Search Online
Checking your monitor’s size online is another easy way to find out how large your monitor is. You can use multiple ways to get your monitor size online.
Method 1: There are many online tools available to you through search engines such as Google that will help you determine the screen size of your monitor.

Method 3: For accurate information regarding the model of the monitor you are using, you are advised to go to the official website for the brand of the monitor you are using.
Method 4: Enter the model number of your monitor in the search bar of their website or peruse the website to find out the monitor’s sizing information.
Final Thoughts
Monitor size is an important factor to consider when choosing a new computer. The wrong size monitor can lead to eye and neck strain, among other health problems.
