PPI and DPI are two important terms that anyone who works with images should know. Both define the resolution, or clarity, of an image but each refers to separate media—that is, digital versus print.

PPI and DPI are often used interchangeably when they shouldn’t be. Understanding how they are different and how to apply each in your projects will empower you to produce a quality print, to optimize digital images for web and ultimately to save yourself valuable time. With that said, let’s deconstruct what these terms mean and get into the differences between PPI and DPI.

- What is the difference between PPI and DPI?

PPI describes the resolution in pixels of a digital image whereas DPI describes the amount of ink dots on a printed image.

Though PPI largely refers to screen display, it also affects the print size of your design and thus the quality of the output. DPI, on the other hand, has nothing to do with anything digital and primarily concerns print.
