How to Check Monitor Size in Inches By Measuring?

Are you wondering how big is my monitor inches? The method below is precise and will help you with that query.

To determine, you may use either a measuring tape or a ruler. However, I prefer the measuring tape because it won’t scratch your screen.

The diagonal length of a laptop’s screen is measured in the same way that monitors are measured: from the upper left corner to the lower-right corner or from the upper right corner to the lower-left corner.

However, please remember that the bezel is not included in the dimension. The laptop’s diagonal size is usually between 11″ and 17.” However, you must include the bezel in the measurement if you wish to buy screen protection or any other privacy device for your laptop.


The process for measuring a monitor screen is as follows.

  1. Measure the width and height of your computer screen diagonally. Remember to ignore the computer’s frame and solely measure the screen size as you align your measuring tape or ruler to the top-left corner.
  2. The size of your diagonal measurement should match the diagonal measurement of your frameless screen exactly.
  3. Excluding the frame, measure the apparent height and breadth of your screen. These should also match the dimensions of the computer monitor filter you’ll use.


How can I determine the size of my screen in Windows 10?

The simplest way to determine your screen size is to use the processes previously discussed to assess your model’s characteristics.

You can measure it physically or online or check the backside of your computer for information on display size.

What is the difference between a screen’s resolution and its size?

The physical dimensions of the display, excluding the bezels, are referred to as screen size. On the other hand, screen resolution refers to the number of pixels that make up the screen. Therefore, regardless of the size of your display, you can alter the screen resolutions.


Choosing the right screen size is as crucial for enhancing your work abilities. You can make an online search on the manufacturer or other reputable websites. The best range to consider for computer monitor physical sizes is between 24 and 30 inches. These monitor screen sizes are ideal for working from home and are popular among online gamers.
