Convert pixels to print size
Print width in inches equals pixel width divided by DPI. Print height uses the same formula. A 3600 × 2400 pixel image at 300 DPI prints at 12 × 8 inches.
| Target quality | Resolution | 3600 × 2400 px print |
|---|---|---|
| Excellent | 300 DPI | 12 × 8 in |
| Very good | 240 DPI | 15 × 10 in |
| Good | 200 DPI | 18 × 12 in |
| Large format | 150 DPI | 24 × 16 in |
Which DPI should you choose?
Use 300 DPI for detailed photo prints viewed closely. A target of 240 DPI is often visually strong for framed prints, while 150 to 200 DPI can work for larger output viewed from farther away. Ask the print provider for its production specification when color and sharpness are critical.
Pixels, DPI, and resizing
Reducing the target DPI increases calculated print size, but it does not increase source detail. Upscaling can create additional pixels through interpolation, yet it cannot recover fine information that was not captured by the original image.
Frequently asked questions
How many pixels are needed for an 8 × 10 print?
At 300 DPI, an 8 × 10 inch print needs 2400 × 3000 pixels. At 240 DPI, it needs 1920 × 2400 pixels.
How do I convert inches to pixels?
Multiply the desired size in inches by DPI. A 6 inch edge at 300 DPI requires 1800 pixels.
Why are centimeters slightly different after rounding?
One inch equals exactly 2.54 centimeters. The calculator preserves the precise conversion and only rounds the displayed result.
