Frequently Asked Questions

Common questions about Print Size and DPI Calculator, formulas, and expected usage.

How do pixels and DPI determine print size?

Print width equals pixel width divided by DPI, and print height equals pixel height divided by DPI.

Is 300 DPI required for every print?

Not always. Higher DPI is common for close viewing, while larger prints can look great at lower DPI when viewed farther away.

Can this estimate effective DPI for a target print?

Yes. Use print dimensions and image pixel dimensions to estimate achieved DPI in each direction.

Why include megapixels in the results?

Megapixels provide a quick quality reference and help compare files when planning print output.
