DPI, or dots per inch, is a measure of the resolution of a printed document or digital scan. The higher the dot density, the higher the resolution of the print or scan. Typically, DPI is the measure of the number of dots that can be placed in a line across one inch, or 2.54 centimeters.

How do you calculate dot per inch?

People regularly discuss digital images in terms of DPI, which stands for Dots Per Inch. The DPI of a digital image is calculated by dividing the total number of dots wide by the total number of inches wide OR by calculating the total number of dots high by the total number of inches high.

Is 300 PPI the same as 300 DPI?

PPI refers to how many pixels per inch there are in a digital image. So, technically, it's PPI until you have a physically printed image, then it becomes DPI and vice versa. However, pixels and dots are pretty much interchangeable. A 300 PPI image will still be a 300 DPI image.
