Pixels Per Inch

• Pixels Per Inch (PPI) describes Image Resolution which refers to the Number of Pixels contained within Each Inch of a Digital Image.

  • A Higher Resolution/PPI Image contains More Pixels and is a Higher Quality of Image.

  • A Lower Resolution/PPI Image contains Less Pixels and is a Lower Quality of Image.

To Calculate PPI:

• Number of pixels ÷ size of the image in inches = Pixels Per Inch.

• Substitute 1 cm for 1 Inch to find Pixels Per Centimeter or PPcm².
