How to Measure Monitor Size

Whenever we watch desktops, laptops, TVs, etc., online, they usually indicate the size of the display. For example, we know that the Apple MacBook Air comes with a 13.3-inch screen.

So, what is the easiest way to measure the size of a monitor?

How to Measure Monitor Size

Measuring monitor size:

  1. Measure the tape and estimate the diagonal length of the display area.
  2. You need to measure it from one corner of the screen to the opposite end of the screen. This will give you the correct screen size.

Another quick and easy way to find out the size of your monitor is to look for an online model.

Google model number, and you will get the size. And again, this would mean that you have to spend on these processes.For further info check our top rated monitors for students.

Steps to measure monitor size

For a CRT Display

Yes, it is doubtful you are using older tech CRT displays, but some people and organizations still use them.

Measuring the display size of a CRT monitor requires a different approach than measuring the size of a new display.

You will need to measure the tape and check the length from one corner of the monitor, including the non-display part, diagonally to the other end.

For an LCD/LED display

If you want to know the display size for any non-CRT display, the process is very straightforward. Check our recommendations on the top printers for students.

 You need to measure the diagonal length of the display to determine the size.

On display, delete the template and measure the screen from one end to the other.

Use the same steps as the display to measure the size of your TV, laptop, desktop, or any other electronic device.

Methods of calculating display area

There is a lot of speculation as to what the definition of display size is.

If you want to invest a good amount in the display, you need to know about size calculation.

Calculating the Monitor Size

The nominal size of the display is one of the most common ways to calculate its size. This is the diagonal length measured from one corner of the monitor area to the opposite end.

Calculating the Viewable Area

The viewable area is part of the display. This will always be less than the nominal size of the monitor because it does not include the size of the template.

This is calculated by measuring one corner of the display area to the diagonal end of the display area.

Calculating the Aspect Ratio

The most important size for some users is the metric aspect ratio. It is not directly related to the size of the monitor but to the layout and design factor.

The aspect ratio tells us the relationship between the length and width of the monitor. 4: 3 for standard displays and 16: 9 for widescreen displays are the most common.

Calculating the Image area

If you are interested in calculating the total area of ​​the display or image area, you need to follow two steps.

  • First, measure the tape and calculate the length of the display (not the monitor)
  • Then measure the height of the show.
  • Multiplying both will give you the total display area.
