What Size Is My Monitor?

The easiest way for you to know your monitor’s size is to check its manual. If you can’t find it, you can measure the screen diagonally from the top left corner to the bottom-right corner using a measuring tape.

Don’t include the frame of the monitor in your measurement, just the screen only. Fortunately, most measuring tapes today contain both the imperial and metric systems of measurements.

The visible way to size a computer monitor is to measure its screen physically. Pull out the measuring tape and start measuring the screen from the top-left corner, on the inside of the bezel. That means you do not include the screen frame in your measurement, just the screen only.

Pull the measuring tape down to the bottom right corner of the screen; again, do not include the bezel. Then look at where that corner lands on the tape. That number on the tape is the size of your monitor, in inches.

Here are the steps you can follow to measure your computer’s screen:

  • Measure the diagonal of the computer screen. Remember, the corner edge of the computer frame is not included, but just the visual screen.

The size of this diagonal measurement should perfectly match the diagonal measurement of the frameless screen.

They should also match the width and height of the filter that you want to buy.

How to Measure the Size of a Laptop Screen?

Laptop screens are also measured in the same way as computer monitors:

1. Measure the Diagonal Distance

Take the diagonal distance from the upper left corner (inside the bezel) down to the bottom right corner (inside the bezel), and that will give you the screen size of your laptop.

2. Measure the Height and Width

Laptop screens usually range from 11 to 17 inches. But if you want to buy a protective filter to put on top of the screen, you should also measure the height and the width of the screen.

Most laptops have bezels; therefore, all of the measurements you will take should be within or inside the bezel.

Measure the screen’s height from bottom to top (inside the bezel) and do the same thing with its width. Most laptop screen filters are specified as width times height or W x H, all in inches.

3. As an Alternative, You Can Use Google
