Find the DPI you get for a print of a given width, and the largest clean print.
The achieved DPI is the pixel width divided by the print width, and the largest clean print shrinks as target DPI rises. Most prints look sharp around 300 DPI, but larger prints are viewed from farther away and need less density.
Print DPI Required
Achieved DPI = pixels / print width; max size = pixels / target DPI
Achieved DPI = pixels / print width; max size = pixels / target DPI The achieved DPI is the pixel width divided by the print width, and the largest clean print shrinks as target DPI rises.
Most prints look sharp around 300 DPI, but larger prints are viewed from farther away and need less density.
This calculator takes 3 inputs: Pixel width, Print width, Target DPI. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
