The paper size guide you need

Paper sizes can be confusing but this guide will clear your doubts. We use 2 types of paper sizes, A sizes and B sizes.

A sizes are the more commonly known format used, everyone is generally aware of the standard A4. B sizes are in between A sizes, for example, A4 > B5 > A5

A sizes are halves of themselves. 1/2 A3 = A4 or 1/2 A4 = A5 etc.

The following list is in order of size
