The safe quick rule: pixels ÷ 300 = inches. If your image is 6000×4000 px, a crisp 300 DPI print is about 20×13.3 in. Want this done for you? Try Max Print Size (by MP).
Common megapixels → 300 DPI print sizes
Approximate max size at ~3:2 aspect. You can go larger for posters viewed from farther away (150–200 DPI is often fine). For exact conversions, use the Print Size Calculator.

Rules of thumb
- Close viewing (photos, fine art): aim for ~300 DPI.
- Posters viewed from a distance: 150–200 DPI usually looks great.
- Short on pixels? Upscale first, then export the exact print size.
