Screen Resolution Calculator

A screen resolution calculator is a tool used to calculate the number of pixels of your screen. It can be used for monitors, televisions, and even your smartphone.

How does a monitor calculate resolution?

A monitor calculates the resolution by dividing the width by the height. The higher this ratio is, the more pixels it has on its display. For example, if a monitor has a width of 1920px and a height of 1080px, it will have 1920/1080=2.0725 or 2.0725 million pixels per square inch (PPI).
