What is A2 Poster size?

A2 Poster Size

A2 poster size measures 420mm x 594mm or 16.53 x 23.39 inch.

A2 size is typically used for posters, drawings and outdoor advertising.

Part of the ISO 216 standard

A2 is part of a set or range of page sizes, called the ISO A or ISO 216 standard. This international standard is based on the German DIN 476 standard from 1922. A5 is actually often referred to as DIN A5. The Japanese have adopted the same range of paper sizes in their JIS P 0138-61 standard.

By folding an A2 in two along its shortest side, you create an A3 poster. Two A2 pages next to each other in a spread equals the A1 paper size.  This is a great way to understand the size.

What resolution required to print a picture on a A2 poster size?

For A2 poster size,  150dpi is a good resolution. A2 is 16.53 x 23.39 inch. So if you use the full image (no crop) you’ll be fine. Always save your work at 300dpi and as a JPEG or PDF.
