What is DPI?

DPI (Dots Per Inch), sometimes called PPI (Pixels Per Inch), describes how many pixels fit into one printed inch. It does not change the pixel dimensions of your image; it only tells printers and software how large to render each pixel. Common values:

  • 72 DPI Standard for web and screens. Keeps file size small.
  • 150 DPI Good for draft prints and documents.
  • 300 DPI Industry standard for professional print (photos, flyers, business cards).
  • 350 DPI Used in magazine and CMYK offset printing.
  • 600 DPI Ultra high quality for fine art and detailed prints.

Frequently Asked Questions

No. Changing DPI only modifies the metadata that tells printers how many pixels to fit per inch. The actual pixel content of your image remains identical.

Lowering DPI increases the physical print size (each pixel takes more space), while raising DPI decreases it. The pixel dimensions stay the same. Only the print dimensions change.

300 DPI is the standard for most professional print work (photos, brochures, business cards). For billboards and large format prints viewed from a distance, 150 DPI is often sufficient.
