Overview
A1 paper measures 594 × 841 mm, or about 23.39 × 33.11 inches. It sits between A0 and A2 in the ISO A series, so it is much larger than ordinary office paper and normally belongs in print-shop or large-format workflows.
Use A1 when a poster, drawing, or wall reference needs to stay readable from a distance. For PaperGens workflows, proof the layout on A3, A2, or 11x17 first, then export the final PDF at the exact A1 page size.
