Size of monitors people use varies with the monitor they use. One can find desktop computer monitors in a wide range of sizes. They are available from 13 to 43 inches. Some users may utilize their TV as a monitor, with screen sizes of 84 inches or more. While laptop screens sizes range from 11.6 to 17 inches. If you have questioned that, how to measure monitor size, you are at right place,
There are different methods via which you can measure monitor screen. For desktops and laptops, the monitor or screen is measured from the top left-corner to the bottom-right corner, in inches.
Then following are the methods you can use and learn about how to measure computer monitor size.
How to Measure Monitor Screen Size?
There are three main methods with the help of which you can measure the size of the monitor.
- With measuring tape.
- With Pythagoras theorem
- Using model numbers.
Let’s discuss each of them.
How To Measure Monitor Size with Measuring Tape?
The simplest method to measure a computer monitor is with a measuring tape or a ruler. Size of screen and area of monitor both can measure with the help of measuring tape or a ruler.
The computer or the laptop manual will mention the monitor size. Manufacturers sometimes display it on a sticker on the device. But if you can’t spot it anywhere, you can measure the size of screen by following steps,
Measure the Length
Use a measuring tape of sufficient length.
Start from the top-left corner and stretch it along the diagonal to the opposite bottom-right. If you start from the top-right corner, pull it straight to the bottom-left corner.
Measure only the screen and not the bezel or the casing around the screen. The diagonal measure is the screen size.
Measure The Height of Monitor
Use a measuring tape and measure the length horizontally of your monitor from one point to the other. Do not include the structure or frame around the monitor, only measure the viewing screen.
Then measure the height of the monitor screen excluding the frame.
Multiply the length by the height and as answer you will get the area of monitor.
How To Measure Monitor Size Using Pythagoras Theorem?
The Pythagoras theorem is an alternative method to measure a computer monitor. It states that
“In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides.”
In a computer monitor, the diagonal measure is the hypotenuse, and it gives you the screen size.
- Determine the diagonal of the screen.
- Measure the width and height of screen.
- Calculate the sum of their squares.
- Find the square root of the answer.
- Finally, the final value that you will obtained is the diagonal size of the monitor.
- You can add the obtained number or multiply it by 2. It will give you the measurement of your monitor size.

How To Measure Computer Monitor Screen Using Model Number?
Check the model number of your laptop or desktop. Typically, you’ll find your monitor size embedded into the model number of your computer. For example, an Acer 20-inch screen could have a model number of S201HL. The “20” after the “S” is the size of the monitor, in this case, 20 inches. In general, a model number starts with one or two letters, followed by numbers. The first two numbers after the letters usually represent the size of the monitor. If you’re still unsure, a quick online search of the model number provides you the exact size.
You can also read your computer monitor manual for sizing information.
Usually, the aim of determining monitor size is to choose a display that is perfect for your application or as a means of establishing the correct dimensions for a filter. When it comes to computer monitor physical sizes, the best range to consider is from around 24 inches to 30 inches.
Such monitor screen sizes are the most suitable for work from home purposes and even a favorite among online gamers. The above methods on how to measure monitor screen size will measure size accurately.
