Start at the top-left corner and extend it along the diagonal to the opposite bottom-right. If you start from the top-right corner, pull it straight to the bottom-left corner.

In a computer monitor, the hypotenuse is the diagonal measure that gives you the screen size. Measure the width and height of the screen, square the screen’s width and the height, and add the two numbers together. Calculate the square root of this sum to get the diagonal measurement and the screen size.

Add the two numbers together (133.8+42.38 =176.18). Find the square root of the sum (√176.18 = 13.27). 13.3 inches is the advertised size of a Dell XPS 13 laptop monitor.
Tip:
There are online calculators like Omni Calculator that quickly estimate the dimensions with the diagonal, width, or height.
