Paper Sizes – ISO 216 Standard
The ISO 216 is an international standard for paper sizes used around the world. The standard defines three paper sizes, known as “A”, “B” and “C” Series.
A Series
Use our visual tool below to understand the A Series. The largest A Size available is A0, which when folded in half becomes A1. This pattern is continued through the whole A Series. The smallest A size available is the A8.

A0 | 841 | 1189 |
A1 | 594 | 841 |
A2 | 420 | 594 |
