DpiCalc
Calculate print resolution

No universal pixels-per-inch assumption

Convert pixels to inches at a stated PPI

Pixels become a physical length only after you state the print density. The calculator keeps that assumption visible.

Known values

Enter whole pixel dimensions and the PPI used for printing.

DpiCalc solves pixel arithmetic only. It does not inspect files, resample, crop, add bleed, predict perceived quality, or equate source PPI with printer hardware DPI.
