Re: Great article

The short and long sides of a sheet of paper are in the ratio 1:sqrt(2), which also happens to be equal by definition to sqrt(2):2. (The ratio must be constant for all paper sizes, otherwise, you might have problems reducing or enlarging since things will only ever fit perfectly axis) At this particular ratio, you can make the next sized sheet up by sticking two sheets together, or the next size down by cutting one sheet in half, and there is no wastage.

297 / 420 = approximately 210 / 297 = approximately 148 / 210.
