How to Measure the Size of the Monitor? [Guide]

If you are going to buy a new monitor or an LCD for your tv room and want to know what size you have been using before and what size you want to buy now, you are at the right place.

If you are using your monitor screen now you can easily determine the size of your display without even getting up.

You can take help from the internet by checking the display options. Or there is another way, if you have your monitor papers saved yet, you can check from their manual too. Simply put if you know your model number you can just put it on the internet and determine your monitor size.

Per se, if you have lost your monitor’s manual as many people tend to do that. You should at least remember your model number but if you have forgotten that too. No need to worry, there are other ways to determine your monitor size.

How Can I Know the Size of My Monitor?

The most forthright approach would be to go for manual. Most of the company’s selling displays add and complete introductory manual in product packaging.

If the manual is misplaced or lost then there are other methods to measure your monitor size. With the help of a measuring tape or a ruler, you can measure the size of your monitor from the top left corner to the bottom right corner.

Determination of Display Area

First, with the help of a measuring ruler measure the screen length. You can do that by placing your ruler on side of the screen and taking the reading. Here’s a trick now, when you take that reading, don’t include the frame of casing surrounding the sides of your computer. As companies don’t add frame size in display size readings. It’ll help you get an accurate reading.

Secondly, with the help of your ruler take the vertical reading of your display. Again, do not add a frame of your computer to reading. Just the screen that displays graphic pictures.

Now, you will multiply both readings that you took. That is the length and height of your screen. For example, if you have a height of 15’’ and a length of 8’, after multiplication, you’ll get the monitor’s image area of 120 square inches.

How to Find Out the Aspect Ratio?

The aspect ratio is the ratio of the screen’s length to its height. Classically computers are produced with an aspect ratio of 16:9, 21:9, and 4:3 ratio.

If you follow the steps given below you can precisely determine the aspect ratio of your monitor.

First of all, take a ruler and measure the vertical height of your computer from top to bottom. While taking the reading keep in mind not to include the frame of your display in the reading. For precise reading, the frame should be excluded and only the area of the screen that displays graphic images should be added.

Secondly, with the help of a ruler measure the length of your monitor. Again, keep in mind not to include frame structure in your reading. Tio’s for height and length.

The last step would be to make ratios for height and length. For example, if you measured height 12’’ and length 18’’ the aspect ratio of your monitor will be 12: 18. You can increase and decrease the value but the ratio will stay the same.

Measurement of Diagonal Area

Typically, to measure the size of the monitor, people go with the diagonal method. It is, simply, to say the most effective and successful method. You can follow the given steps below to measure the screen display diagonally.

First of all, what is a diagonal area? It is the distance from the lower corner of one side to the upper corner of the opposite side. Therefore, what you need to measure here is the distance from the top left corner of your screen to the bottom right corner or from the bottom right corner to the upper left corner.

The most important thing you need to keep in mind is not to include the frame structure of your monitor in taking a reading. The companies making these products do not include the frame structure in screen display or monitor display size.

In order to take the measurement, take the readings of the height and length of the screen. After that, you can add both the shared values and calculate the square root of the added sum. If you follow all the steps, it’ll give you the diagonal value of your monitor display.

Frequently Asked Questions (FAQs)

How to Find Out What is the Size of Your Monitor?

You can easily find out your display size by use of a manual given to you by a production company or by the model number of your given monitor. You can also measure it by measuring tape. Either of the above-mentioned steps can be used for the measurement of your monitor.

How Do You Measure the Size of a Curved Monitor?

A:  Unexpectedly, you can find out the size of your cured monitor in the same way as that of the flat monitor. You can either use the diagonal measurement method as stated above or with the help of the Pythagoras theorem.

How Can I Measure the Image Area of a Monitor?

A: The image area of your monitor is the area that displays the graphic images. This area excludes the frame structure of your monitor, including only the screen area. To find the measurement of image rea, multiply the length, and height of the screen.

Conclusion

In conclusion, it does not matter which method you have used to get the measurement, as far as you take the correct reading you can get your size of monitor easily. Always exclude the bezel or casing around the monitor during measure, and taking readings. If you by mistake include the frame structure, it will compromise the precise measurement of your monitor.

The diagonal area i.e., from the top right corner of one side to the bottom left corner of the other side is referred to as screen size. There are three ways through which you can measure the screen size, the aspect ratio, image area, or also referred to as the diagonal area of your monitor.

For using either of the above-mentioned steps you must have a measuring ruler or tape. In some cases, people are unable to measure the size of their monitor, they can use the Pythagoras theorem to get a precise value of their monitor size.
