A0 is a square meter, and everything in the A series has an aspect ratio of sqrt(2) and different sizes are achieved by simply folding (or cutting) in half. It's actually pretty neat... check out:

(When you are not in the printing-business). The thing with cutting in half is more essential to it, than that it is based on square meter. Also, even when it is an square meter, the sides are something "odd" because the ratio is fixed.
