Required Pixels for Printing

To calculate required pixels, multiply the print size in inches by the target PPI. A 12 × 18 inch print at 300 PPI needs 3600 × 5400 pixels (about 19.4 megapixels).

Required Pixels Formula

Required width (px) = print width (in) × PPI. Pixel results are rounded up so the image never falls below your quality target. When working in centimeters or millimeters, the size is converted to inches first.

What Resolution Do I Need for Printing?

Use 300 PPI for close-up photo prints. For posters and larger prints viewed from farther away, 200 or 150 PPI is often sufficient and lets you print larger from the same image.
