Resolution

This value relates mainly to printing. The resolution determines how many pixels would be inside a centimeter or inch when the file is printed. For example, an image that is to be printed at a size of 4 x 6 inches with a current resolution of 72 Pixels per Inch (PPI) would have a pixel dimensions of 288 x 432 px. The printed image would not be good quality. If we maintained the same pixel dimensions, but changed the resolution to 300 PPI, the image would print out at a size of 0.96 x 1.44 inches, but the print quality would be great. An image that is to be printed at a size of 4 x 6 inches at a resolution of 300 PPI would have a pixel dimensions of 1200 x 1800 px. This image would be of much better quality when printed.
