dots per inch

Dots per inch (DPI) measures the resolution of a printed image or a scanner, indicating how many individual dots of ink or pixels fit into one inch. Higher DPI means more dots or pixels per inch, resulting in a sharper, more detailed image. For example, a 300 DPI printer produces images with 300 dots in each inch, offering clearer print quality. In digital screens, DPI helps determine image sharpness and clarity, especially when resizing or printing. Essentially, DPI quantifies the level of detail achievable in a physical or digital image based on dot density.
