Beautiful reference poster: A-series paper sizes (A0, A1, A2, A3, A4, A5, ...)

A beautiful life-sized A0 poster showing the exact size of all the A-series papers. 

The papers are arranged in a recursive pattern, and overlaid with a long spiral showing the first 1024 digits of √2, the ratio on which the A-series is based.

Each life-sized paper is also overlaid with the length of its longest side in millimetres (mm) including each length's standard ISO tolerances for A-series paper. This makes it serve as a really handy reference for those who frequently work with paper of different sizes.

Available in many different colours! This is ideal to hang on your wall if you frequently work with paper, or as a gift to any visual designer, crafter, number geek, or anyone else wanting a beautiful abstract piece to hand on their walls.
