How To Measure Monitor Size With a Measuring Tape
Desktop computers and laptops come in different screen sizes. It is as essential as screen resolution as it is critical to productivity. The correct measurement can also help you figure out the size of a screen filter you need to buy. Screen size is the actual physical size of the screen and is in inches. The simplest method to measure a computer monitor is with a measuring tape or a ruler. The computer or the laptop manual will mention the monitor size. Manufacturers sometimes display it on a sticker on the device. But if you can’t spot it anywhere, you can measure the size of your existing monitor or a new one you are interested in buying with the help of a measuring tape.
How To Measure Monitor Size With Simple Math
The Pythagorean theorem is an alternative method to measure a computer monitor. It states in a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides. 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. For instance, a Dell XPS 13 has a screen width of 11.57 inches and a height of 6.51 inches. Multiply the width by itself to get 133.8. Then multiply the height by itself to get 42.38. 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.
