Method
inches = pixels / DPI; centimeters = inches × 2.54.
Calculate physical print size from pixel dimensions and DPI.
inches = pixels / DPI; centimeters = inches × 2.54.
Use the result as a transparent planning estimate. Change one assumption at a time, compare scenarios and move to Toolkit when you need system-level simulation.
File DPI metadata does not create detail; effective resolution matters.
