What is the difference between DPI and PPI?
DPI (dots per inch) refers to the physical dots a printer can place per inch. PPI (pixels per inch) refers to the pixel density of a digital screen or image. In practice, these terms are often used interchangeably, but they describe different things.
A printer at 1200 DPI places 1200 ink dots per inch. A screen at 110 PPI displays 110 pixels per inch. An image at 300 PPI has 300 pixels per inch when printed at 100% size.
For digital images: use PPI. For printers: use DPI. When someone says “300 DPI image,” they technically mean 300 PPI.

How do DPI and PPI relate?
Numerically, DPI and PPI use the same value when specifying image resolution for print. A “300 DPI” image file is actually 300 PPI — it has 300 pixels per inch.
The printer then uses its own DPI to reproduce each pixel. A 1200 DPI printer uses ~16 dots (4×4) to reproduce each pixel of a 300 PPI image.
For most practical purposes, DPI and PPI are interchangeable when discussing image resolution. The distinction matters mainly in pre-press and printer calibration.
Practical tips
- Image resolution: always specified in PPI. 300 PPI = print quality, 72 PPI = web.
- Printer resolution: inkjet printers typically 1200–4800 DPI. Laser: 600–1200 DPI.
- Screen PPI: MacBook Pro 14″ = 254 PPI, iPhone 15 = 460 PPI.
- Changing PPI in Photoshop without resampling just changes the print size, not the pixel count.
