Understanding Digital Image Resolution

Digital image resolution quantifies the detail an image holds. It’s typically expressed as the number of individual dots or pixels that can be placed in a line within a one-inch span (DPI or PPI) or other units of length.

  • DPI (Dots Per Inch): Traditionally refers to printer resolution, indicating the density of ink dots a printer can produce.
  • PPI (Pixels Per Inch): Refers to the pixel density of a digital image or a display screen.

In many contexts, especially when preparing digital images for print, DPI and PPI are used interchangeably to describe the image’s pixel density. This converter treats them as numerically equivalent for density conversion purposes.

Common Resolution Units & Typical Applications
Unit Typical Application Example Value
DPI / PPI Web Images 72 – 96 DPI/PPI
DPI / PPI Newspaper Print ~150 DPI/PPI
DPI / PPI Magazine/Brochure Print 300 DPI/PPI
DPI / PPI High-Quality Photo Print 300 – 600 DPI/PPI
d/cm or pixel/cm Metric system measurements ~118 d/cm (for 300 DPI)
