FAQ
What is aspect ratio and why does it matter for printing?
Aspect ratio is the width-to-height proportion (e.g., 3:2, 4:3, 16:9). It determines how your image fits standard print sizes without unwanted cropping or borders.
How do I calculate print size from pixels?
Divide image pixels by DPI/PPI. For example, 6000×4000 px at 300 DPI ≈ 20×13.3 in (≈ 50.8×33.8 cm). Our print size calculator does this instantly and shows max and recommended sizes.
What DPI should I use for high-quality prints?
For fine-art and close viewing, aim for 300 DPI. For large posters viewed from farther away, 180–240 DPI often looks excellent.
What’s the difference between DPI and PPI?
PPI describes pixel density in your file; DPI is the printer’s dot density. In practice, people say DPI for print sizing.
How big can I print my photo?
Use our max print size result. It’s computed from your pixel dimensions and target DPI to keep quality sharp and gallery-ready.
What if my DPI is too low?
Choose a smaller print, view from farther away, or start with a higher-resolution file. For artwork, professional scanning can help capture more detail.
Can I use this for social media crops?
Yes. Knowing your aspect ratio helps adapt images to platform-specific sizes while protecting composition before you print.
