DPI Calculator

Calculate DPI for printing images at different sizes.

How to Do It Manually

DPI (dots per inch) measures print resolution. Divide the pixel dimension by the physical print size in inches.

DPI = Pixels ÷ Inches
  1. Know your image pixel dimensions (e.g. 3000 × 2000 px).
  2. Know the desired print size in inches (e.g. 10 × 6.67 in).
  3. DPI = pixel dimension ÷ print dimension (3000 ÷ 10 = 300 DPI).

Frequently Asked Questions

What DPI is good for printing?

300 DPI is the standard for high-quality photo printing. 150 DPI is acceptable for large format prints viewed from a distance.

What is PPI vs. DPI?

PPI (pixels per inch) refers to screen resolution. DPI (dots per inch) refers to printer output. They are often used interchangeably but technically differ.
