How To Measure Monitor Size

How do you measure the size of the monitor? Monitor height is defined as the distance that extends from the top left corner of the visible screen area to the corner that is diagonally opposite from it. The actual viewing area on a CRT monitor is typically around an inch less than the size of the screen itself.

What Is the Monitor Size? How Are Monitors Measured?

The monitor size is measured diagonally (one corner to the opposite corner). Although many manufacturers make their monitors with slightly smaller dimensions to save on raw materials and shipping costs. This means that although the screen may be 32-inches measured across the front of the screen, it is 31.5 inches (81.6 cm) diagonally.



How to Find Out Monitor Size?


To find the diagonal monitor size, you need to multiply the vertical by the horizontal dimensions of your screen (or vice versa). So if your monitor is 21 inches x 13 inches (53 x 33 cm), then multiply these figures together and you get 238.5 cm or 7 ft 6 inches.

Monitor sizes, measured diagonally, may be slightly different from the specified size because of manufacturing tolerances. Monitor manufacturers often put a slightly smaller monitor case on a larger working screen to save costs and pass the savings on to you.


Why Is It Important to Know Your Monitor Size?


Monitor sizes can vary from 19 inches to 27 inches, and larger. If you’re planning to set up a home office, the size of your monitor is crucial. It could save you money in the long run by getting a bigger model ahead of time.

For example, if you have an older 17-inch monitor and you’ve just bought a new computer that uses a widescreen monitor, the size of your screen may be different. The older 17-inch monitor is taller than the newer 21-inch model because it’s designed to show the same resolution as the larger monitor.

This means there will be space on either side of your documents and images. This wastes space and doesn’t take full advantage of the larger screen area offered by the widescreen monitor.

If you’re upgrading your computer, you’ll need to buy a bigger monitor as well. If you don’t, not only will your images and text be smaller (which can make them difficult to read), but many applications won’t work because they were designed for a screen with a different aspect ratio.


How to Measure Size of Computer Monitors


To measure the size of a desktop computer monitor, start from one corner of the screen by following these steps:

  1. Turn off the monitor and unplug it from the wall outlet.

  2. Lay a straight edge or ruler flat on top of the screen with its back edge along the left or right side then measure across to the opposite side.

  3. Add the two measurements together to get the diagonal monitor size in inches or centimeters.



How to Measure Monitor Size of Laptop Computer


To measure the size of a laptop monitor, start from one corner and follow these steps:

  1. Turn off the monitor and unplug it from the power source.

  2. Lay a straight edge or ruler flat across the top of the screen to find its center point then measure diagonally in both directions to opposite sides.

  3. Add the two measurements together to get the diagonal monitor size in inches or centimeters.

  4. Multiply that number by 1.5 to find the total width and height of the screen (allowing for bezels) in inches or centimeters.


Check Screen Size by Model Number


To find the size of your monitor, you will need to look at the model number. The model number may be printed directly on the front or back of your computer screen, or it may be printed on a sticker located somewhere else such as on the side or bottom of the monitor case.

Once you have found and written down this information, you can compare the first and second numbers to determine the monitor size in inches or centimeters. For example, if your monitor model number is C1934SW, the first digit ‘3’ tells you that this is a 19-inch monitor. The second digit ‘4’ tells you that this monitor has a 4:3 aspect ratio


Checking Monitor Size by Manufacturer’s Specifications


To find out the screen size of your monitor, you will need to refer to your computer’s documentation or do an Internet search for “monitor dimensions” using the model number you have written down.

You may be able to find this information on a manufacturer’s website. For example, looking at the Acer monitor model numbers below shows us that an Acer AL1916 has a 19-inch screen and a 4:3 aspect ratio.



How to Diagonal Measurement Your Monitor Screen Using a Measuring Tape?


To find out the diagonal monitor size, buy a measuring tape and use it to measure from one corner of your screen to another.

If you don’t have a tape measure handy, you can also use a ruler but this method will not be as accurate because the markings on the ruler may not match up with your screen size exactly.


Without Measuring, How Can I Tell What Size My Monitor Is


If you don’t have a ruler or measuring tape nearby, there is another way to determine your monitor size using just an Internet browser.

Most browsers allow you to resize the screen by pressing CTRL and scrolling down with the wheel on your mouse (on a PC) or scrolling down with two fingers (on a Mac).

Start by maximizing the browser window and then resize it, looking at the listed screen resolution to determine if that matches your monitor. You may have to try this a couple of times before you get an accurate idea about your monitor size this way.


What Is the Best Size for a Monitor?


The best monitor size is completely subjective. It depends on your desk space, viewing distance, and how you use the computer.

If you sit closer to your screen or have limited desk space, go for a smaller monitor.

On the other hand, if you prefer to keep some distance between yourself and the screen or want more details in your work, a larger monitor may suit your needs better.


What Are the Most Frequently Used Monitor Sizes?


The most popular monitor sizes are 17-inch, 19-inch, 21.5-inch, 23-inch, and 24-inch.


What Is the Size of A Monitor with A 24-Inch Screen?


A monitor with a 24-inch size is approximately 60 centimeters wide and 50 centimeters high. This includes the frame and bezels though, so you will need to add about 20 centimeters on each side for the total width and height of the visible screen area.


What Is the Difference Between Screen Resolution and Screen Size?


The size of the screen is measured in inches or centimeters diagonally. This measurement indicates how big the monitor looks from an average distance away.

Screen resolution, on the other hand, is measured by pixels and indicated by width x height. It tells us about the sharpness of images displayed on your screen. While a larger screen size means that you will see more content on the screen at once, a higher pixel resolution means that this content will be displayed more sharply.



You Can Also Use Online Calculators


There are several internet calculators accessible like Omnicalculator that can quickly compute the dimensions with the diagonal, breadth, or height. Enter one, and the program will calculate the other two dimensions as soon as you finish entering them.


How Big Is a 22 Screen?


A 22-inch screen is approximately 56 centimeters wide and 45 centimeters tall. This includes the frame and bezels though, so you will need to add about 20 centimeters on each side for the total width and height of the visible screen area.


What Does 27 Inch Monitor Mean?


A monitor with a 27-inch size is approximately 68 centimeters wide and 55 centimeters high. This includes the frame and bezels though, so you will need to add about 20 centimeters on each side for the total width and height of the visible screen area.


Is 27-Inch Monitor Too Big?


A 27-inch monitor is considered relatively large, but it isn’t considered huge. If your desk space allows for it, you might benefit from the extra screen area.


Is 27 a Good Monitor Size?


A 27-inch monitor is well suited for tasks that require a lot of screen space and multiple windows. It’s also ideal if you like to sit close to the screen because it provides more detailed content than smaller monitors do.


How Wide Is 27inch Monitor?


A 27-inch monitor has a width of 68 centimeters from one edge to the other.




It doesn't matter whatsoever method you choose to determine the size of the monitor; all you need to do is keep the following considerations in mind.

When measuring the size of your monitor's screen using a ruler or measuring tape, you should never include the shell or bezel that surrounds your display. Inaccurate readings are certain to result in the event that you factor in the monitor's housing or the surrounding structure.

The diagonal distance that may be measured from the top-right corner to the bottom-left corner, or vice versa, is referred to as the screen size.

When it comes to determining the size of a monitor, there are three distinct criteria that may be measured. The aspect ratio, image area, and diagonal measurement of your display are their respective names.

You are required to arm yourself with either a ruler or a measuring tape in order to measure any of the two characteristics that were discussed before in this paragraph.

In the event that you are unable to physically measure the diagonal of your screen, you may always use pythagoras' theorem to compute the diagonal, and you will be able to do it in a matter of minutes.
