What the result is useful for

Required Resolution 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

Required pixels = final print inches × target PPI on each axis.

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.
