Formula
How to calculate this size
98.4 mm x 300 PPI = 1,162 px wide.
Use this when the artwork stops at the finished edge.
Add 0 mm per side before calculating pixels when artwork reaches the edge.
Common mistakes
Avoid these monarch envelope 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.
