A Series Size Relations

A2 paper size is obtained by evenly dividing A0 size into 4 parts in the same proportion, so its area is also 1/4 of 1 square meter (the area of A0 size); and it is four times the size of the most common used A4 size. The entire ISO216 paper size series includes A0, A1, A2, A3, A4, A5, A6, A7, A8, A9, A10, etc, size in order from big to small. The size of each number is twice that of the next one, and with actual the same length-width ratio: √2:1.

The following drawing shows the relationship between the sizes of the ISO A size.
