The screen sizes of smartphones are normally published in inches, but in many countries following the metric system, like Europe and India, mobile phone screen sizes are also specified in centimeters. To convert inches into Centimeters multiply the inch value by 2.54 (1 inch =2.54 cms or centimeters). To make screen size in inches from centimeters, divide by 2.54.

In the smartphone screen image here, the screen size is marked as 10.2 cms or 4 inches which is the measurement from the bottom left corner to the top right corner. Smartphone screen sizes can be specified in two different ways: one by the screen diagonal measurement in inches and, two: by the pixel count on the two sides of the phone screen, that is the width and height of the phone screen.

The pixel density or PPi of a phone screen depends on phone screen size in inches and the pixel measurement of the phone screen. More on this from our page about smartphone pixel density PPi
