DPI Calculator
Enter your image dimensions in pixels to calculate the maximum print size at different DPI settings. For sharp photo prints, use 300 DPI. For posters viewed from a distance, 150 DPI is often sufficient.

How to Use This Calculator
- Find your image dimensions in pixels (right-click the file → Properties/Get Info).
- Enter the width and height in the fields above.
- Click "Calculate Print Size" to see the maximum print dimensions at 300, 200, and 150 DPI.
Which DPI Should You Choose?
- 300 DPI — Photo prints, fine art, anything viewed up close. This is the gold standard for photo printing.
- 200 DPI — Acceptable for prints viewed at arm's length. Good for larger prints where 300 DPI isn't achievable.
- 150 DPI — Posters and large prints viewed from 3+ feet away. Acceptable for canvas wraps and wall art.
The Formula
The calculation is straightforward: Maximum Print Size (inches) = Pixel Dimension ÷ DPI. For example, a 4000×3000 pixel image at 300 DPI can print up to 13.33 × 10 inches. To convert to centimeters, multiply inches by 2.54.
