DPI Explained: What 72, 300, and 600 DPI Mean for Print and Screen

DPI, or Dots Per Inch, is a measurement used when preparing images for printing, with different values suited to different purposes. Screen-based work typically uses 72 or 96 DPI, while 300 DPI is the standard for high-quality printed documents such as photos and forms. Higher resolutions like 600 DPI are used in specialized print or scanning workflows that demand greater detail. Importantly, DPI metadata and pixel dimensions are distinct — increasing DPI alone does not add image detail or improve a low-resolution file. Understanding the relationship between DPI, pixel count, and print size helps avoid common errors during image preparation.
