Image Print Size Calculator
Convert image pixels and PPI into maximum print size in inches, centimetres, and millimetres for print planning.
Print readiness
3000×2400px at 300 PPI prints 10×8 in (25.4×20.32 cm). Quality: High. A4 needs 2480×3508px portrait at 300 PPI.
- A4 portrait: danger requires 2480×3508px.
- A4 landscape: danger requires 3508×2480px.
- Portrait shortfall if not enough: 46.2% more pixels on the limiting side.
- Changing DPI metadata does not create image detail.
How to use this result
Start with the target surface: a printed size, a platform canvas, a marketplace image requirement, or a safe-zone overlay. Enter the real pixel dimensions or upload a local image when the tool supports it, then compare the result with the recommended size, ratio, file-size limit, and source note.
Use the copied output as a production checklist rather than as an approval guarantee. The calculator checks measurable dimensions and ratios, while final acceptance can still depend on compression, color, account settings, crop previews, platform policy, or printer-specific export instructions.
FAQ
Is DPI metadata enough?
No. Real print detail comes from actual pixel dimensions.
What is a good print PPI?
300 PPI is high quality, 200 PPI is often usable, and below 150 PPI is risky for close viewing.

Print formulas use standard inch, cm, mm and PPI conversions. Last checked 2026-05-24.
Platform dimensions are centralized in data files. Every platform spec must include sourceConfidence, sourceUrl and lastCheckedAt. Official platform documentation overrides this tool when specifications differ.
