Very Interesting…
If you take a sheet of A-series sized paper and fold it in half, the ratio of height to width remains the same.
To achieve this the ratio of height to width is height = sqrt(2) * width.
The size (area) of A0 is 1 square meter, A1 is 1/2 square meter, …, A4 is 1/16 square meter.
There is A-1 (2 square meters), A-2 (4 square meters) etc.
