Specifications of a Smartphone - PPI

Pixels Per Inch (PPI)

Working out the pixel density, or pixels-per-inch (ppi) of a device can give a good indication of how clear the screen of a smartphone can be.
Having a large device does not mean you will have a super-high resolution. Large screen devices will have a much lower ppi because the pixels are spread across a much larger area.

Calculating PPi
PPI refers to the number of pixels spread across the surface area of the screen, but because screens are measured diagonally it's not as straightforward as multiplying the pixel count going across the device by the number down and then dividing by the diagonal measurement.
The thing with ppi is that the larger the screen, the lower the ppi. This is because a larger screen means the individual pixels have to be larger to fill the space.
