What You'll Learn
Measure the length of the monitor screen
To measure the length of your monitor screen, you will need a measuring tape or a ruler.
First, turn off your monitor and unplug it from its power source. This is an important safety precaution and will also make it easier to see the screen's borders.
Next, place the measuring tape or ruler at the top-left corner of your screen. Measure the horizontal length of the monitor from this corner to the bottom-right corner. Ensure that you only measure the viewing screen and do not include the frame, bezel, or any other structural element in your measurement. The length should be measured in inches or centimetres.
If you want to find the exact dimensions of your monitor, you can also measure the height of the screen separately. Place your ruler or measuring tape at the top edge of the screen and measure down to the bottom edge to determine the height. Again, make sure you only measure the screen itself and not the surrounding frame or bezel.
By measuring the length and height of your monitor screen, you can gain valuable information about your display. These measurements can help you determine the image area, aspect ratio, and diagonal measurement of your screen. Additionally, knowing the size of your monitor can assist in adjusting display settings, choosing compatible accessories, and enhancing your productivity.

Measure the height of the monitor screen
To measure the height of your monitor screen, you will need a ruler or measuring tape.
First, turn off your monitor and unplug it from its power source. This ensures that you are not handling electrical equipment while taking measurements and reduces the risk of electrical shock.
Next, place the ruler or measuring tape at the very top edge of the screen and measure down to the bottom edge. This will give you the vertical height of the screen. Ensure that you only measure the screen and not the bezel or casing around it.
Note the measurement insection. You can also measure the width of the screen in the same way, starting at the left edge of the screen and measuring across to the right edge.
If you want to find the diagonal measurement of your screen, you can do so by measuring from the top-left corner of the screen to the bottom-right corner. This will give you the length of the screen's diagonal, which is typically how screen size is described.
It is important to measure the screen size accurately, especially if you are looking to buy accessories such as monitor stands or wall mounts, as they are designed to fit specific monitor sizes.

Multiply the length by the height to find the image area
To find the image area of your monitor, you need to multiply the length by the height. This will give you the total area of the screen in square units (e.g. square inches or square centimetres).
First, you need to measure the length and height of your monitor screen. It is important to only measure the image area, excluding the frame or border around the monitor. Use a ruler or measuring tape to determine the horizontal length and vertical height of the screen.
For example, let's say your monitor screen has a length of 16 inches (40.6 cm) and a height of 10 inches (25.4 cm). To find the image area, you would multiply the length by the height: 16 x 10 = 160 square inches. So, the image area of this monitor is 160 square inches.
You can also use this method to find the screen area of other devices, such as laptops, smartphones, and tablets. Just make sure to only measure the screen itself and not the bezel or frame around it.
Additionally, if you want to find the diagonal measurement of your monitor, you can use the Pythagorean theorem. Simply square the height and length of the screen, add the two numbers, and then find the square root of the sum. This will give you the diagonal distance.
Knowing the image area and diagonal measurement of your monitor can help you determine the quality of your viewing experience and ensure you have the right setup for your needs.

Determine the aspect ratio by comparing the length and height
The aspect ratio of a screen is the relationship between its height and width, expressed as two numbers separated by a colon. For example, a ratio of 16:9 means the width of the screen is 16 units and the height is 9 units.
To determine the aspect ratio of your monitor, you first need to find its width and height. You can do this by checking your monitor settings on Windows or Mac, or by physically measuring the screen with a tape measure or ruler.
Once you have the width and height, you can calculate the aspect ratio by dividing the width by the height. For example, if your monitor's resolution is 1920 x 1080, you would divide 1920 by 1080, resulting in an aspect ratio of 16:9.
You can also compare this ratio to common aspect ratio standards, such as 16:9 for widescreen TVs and laptops, or 3:2 for iPhone displays up to iPhone 5.
Additionally, you can use online aspect ratio calculators to determine the aspect ratio of your monitor by inputting the width and height measurements. These calculators can also help you resize images or videos for your projects by providing the correct height or width when resizing.
Knowing the aspect ratio of your monitor is essential for various reasons. It can help you choose the right monitor size for your needs, ensure you have the correct setup for an immersive experience, and allow you to adjust your display settings for optimal viewing.

Measure the diagonal distance of the screen
Measuring the diagonal distance of your screen is a straightforward process. It is also a very important measurement to take, as it can help you determine the quality of your viewing experience.
To measure the diagonal distance of your screen, you will need a tape measure or a ruler. If you don't have either of these, you can use a credit card, debit card, library card, or standard ID. First, turn off your monitor and unplug it from any power source. Then, place your measuring tool along the diagonal of the screen, from the top-left corner to the bottom-right corner. Make sure to measure the screen at its widest point to ensure you are capturing the full diagonal. Take the measurement in centimetres or inches.
If you are unable to measure the screen manually, you can also calculate the diagonal distance using the screen's aspect ratio and width and height measurements. To do this, you can use the following formula:
Diagonal screen size = √(height² + width²)
For example, if your monitor has a resolution of 1920 x 1080 and an aspect ratio of 16:9, you would calculate the diagonal screen size as follows:
Diagonal screen size = √(1080² + 1920²) / 96 = 21.5 inches
It is important to note that this calculation assumes that the aspect ratio is expressed as a ratio of width to height. If your aspect ratio is expressed as a ratio of height to width, you will need to rearrange the formula accordingly.
Additionally, there are online tools available that can help you calculate the diagonal distance of your screen. These tools typically require you to input the aspect ratio and at least one dimension, such as width or height.
By following these instructions, you can easily measure or calculate the diagonal distance of your screen, which will help you determine the optimal viewing distance and enhance your viewing experience.
