The simplest way to explain the A sizes is two of one size will equate to 1 of the next size up so for example 2 x A4 pages side by side (portrait) will equate to 1 x A3 page and 2 x A3 pages side by side (portrait) will equate to 1 x A2 size.
The larger the size of paper the smaller the number A10 is the smallest and A0 is the largest.
