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.
| 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) |
