Today we look into an aspect of a device’s screen which has been building up to be quite a trend as of late – the Pixel Density. Our goal is to shed some light on some of the common misconception that people have about it and hopefully answer this question along the way: At what point does Pixel Density can be considered a feature or just marketing gimmick? Definition and Calculation Pixel Density is a way to measure the resolution of a given device. Depending on the device being measured, Pixel Density is represented in various abbreviated terms. • PPI or Pixel per Inch – Similar to DPI, but mainly used for smartphones and tablets. Pixel Density of a display is calculated by dividing the total diagonal resolution in pixels by the screen’s diagonal size in inches. To get the total diagonal resolution in pixels you have to find the square root of the sum of the width resolution and height resolution which are both squared. The PPI sweet spot Now that we have a better understanding of Pixel Density and how it’s calculated, let’s delve deeper in to the ideal pixel density of a screen.
