Formula
How to calculate this size
215.9 mm x 300 PPI = 2,550 px wide.
Use this when the artwork stops at the finished edge.
Add 3 mm per side before calculating pixels when artwork reaches the edge.
Common mistakes
Avoid these legal paper size problems
A paper size needs a PPI target before pixels mean anything for print.
Portrait and landscape use the same dimensions, but width and height swap in the export.
Paper pages show trim size first; add bleed only when the design prints to the edge.
