DPI – PPI – Resolution

DPI: Dot’s per inch. The number of dots in a printed inch. The more dot’s the higher the quality of the print (more sharpness and detail).

DPI: Dot’s per inch. The number of dots in a printed inch. The more dot’s the higher the quality of the print (more sharpness and detail).

PPI: Pixels per inch. Most commonly used to describe the pixel density of a screen (computer monitor, smart phone, etc…) but can also refer to the pixel density of a digital image.

Resolution: Resolution is the measure of pixels in the display, usually expressed in measurements of width x height. For example a monitor that is 1920 x 1080 is 1920 pixels across and 1080 pixels down.

Higher resolution means more detail. Higher DPI means higher resolution. Resolution is not “size”, but it’s often confused with it because higher resolution images are often bigger, but that doesn’t necessarily have to be the case.

Print: 300dpi is standard, sometimes 150 is acceptable but never lower, you may go higher for some situations.

Web/Digital: DPI doesn’t equate to digital as it’s a print measure. It was commonly believed for a long time that 72dpi was ideal for web. If you hear that it’s simply not the way things work. When talking digital, we’re concerned with the actual resolution. How that image prints is another matter.
