概要
A0 paper measures 841 × 1189 mm, or about 33.11 × 46.81 inches. It defines the starting point of the ISO A series: A1 is half of A0, A2 is one quarter of A0, and A4 is sixteen times smaller by area.
A0 is not a desktop-printer format. Treat it as a final output size for print shops, plotters, architectural review boards, and wall-scale references. Proof spacing and hierarchy on A3, A2, or 11x17 before committing to the large sheet.
