How pixel dimensions determine print size
A digital image is a fixed grid of pixels. When you print it, those pixels are spread across paper. The number of pixels you have, divided by how many you place in each inch, gives the physical size: inches = pixels ÷ DPI.
How DPI affects print dimensions
Higher DPI packs pixels more tightly, so the print is smaller but sharper. Lower DPI spreads them out, making the print larger but softer. Halving the DPI doubles both width and height.
Already have a print size in mind? The DPI Calculator tells you the resulting DPI. For a single measurement, use Pixels to Inches.
Example print sizes
| Pixels | 300 DPI | 150 DPI |
|---|---|---|
| 1800 × 1200 | 6 × 4 in | 12 × 8 in |
| 3000 × 2400 | 10 × 8 in | 20 × 16 in |
| 4000 × 3000 | 13.33 × 10 in | 26.67 × 20 in |
| 6000 × 4000 | 20 × 13.33 in | 40 × 26.67 in |
Frequently asked questions
How big can I print a 3000 × 2400 image?
At 300 DPI it prints at 10 × 8 inches (25.4 × 20.32 cm). At 150 DPI the same file prints at 20 × 16 inches, with less detail per inch.
How is print size calculated?
Divide each pixel dimension by the DPI. Width in inches = pixel width ÷ DPI, and the same for height. Multiply inches by 2.54 for centimeters.
Which DPI should I choose?
300 DPI is a common reference for close-viewed, high-quality prints. Lower values such as 150–200 DPI are often fine for larger prints viewed from a distance. Your print service may recommend a specific value.
Will increasing DPI in my editor make the image print larger?
No. Changing the DPI setting without resampling keeps the same pixels and only changes the intended print size. A higher DPI means a smaller, denser print.
