The ISO paper series A and B make sense. A0 or B0 are the parent sizes. Each number take the paper size and cuts it in half. So two A1 sheets equal A0. Two A2 sheets equal 1 A1. In the practical size arena, A4 is the normal size for most documents, and A3 would be twice that size. Making it easy to make larger or smaller copies on the copier. Most copy machines (outside of the US) it is common to have A4 and A3 paper and possibly even A5 paper too. Japan is familiary with the B size paper and most of my notes are on B5 size paper. What about the US? Letter and Legal? How is this even still convenient. As an American who only knew about Letter and Legal, my first experience with the ISO standard was one of frustration. Now that I have more experience, I rather enjoy these sensible sizes that have been thought out. Take a listen to hear more.
