Quick Answer

A4 paper dimensions are 210 x 297 millimeters (8.3 x 11.7 inches). In printable wall art, A4 is the most popular standard page size in the ISO paper ratio family. A high-resolution A4 file can be scaled down to print A5 prints. ResizeFlow automates this setup by automatically upscaling and formatting a single design file into A4 sizes at 300 DPI in seconds.

Understanding the Universal A4 Format

A4 paper is the standard letter-equivalent size used globally outside of North America. It is the default size for documents, flyers, letterheads, and standard home wall prints.
