Quick Answer

A0 paper dimensions are 841 x 1189 millimeters (33.1 x 46.8 inches). In printable wall art, A0 is the largest standard size in the ISO paper ratio family. A high-resolution A0 file can be scaled down to print A1, A2, A3, A4, and A5 prints. ResizeFlow automates this setup by automatically upscaling and formatting a single design file into A0 sizes at 300 DPI in seconds.

Understanding the Giant A0 Format

A0 paper is the baseline for the ISO 216 standard, representing exactly one square meter of area. Due to its large size, it is commonly used for giant exhibition posters and technical drawings.
