DPI vs PPI Print Calculator
This tool calculates image sampling density in PPI. Printer DPI describes output dots and is not interchangeable with image PPI.

What the result is useful for
DPI vs PPI Print Calculator is useful when you need to turn pixel dimensions and a physical output size into a decision about resizing, cropping or whether the source file has enough raster detail.
How the calculation works
Effective PPI = source pixels ÷ final print inches on each axis; the lower axis is the limiting effective resolution.
What this calculator cannot know
The math can describe pixels, PPI and geometry, but it cannot judge subject detail, sharpening, resampling quality, printer process, media or viewing distance. Use the output provider’s requirement when one exists.
