Comparison of A-, B-, and C-series paper sizes

I know the A-series is more common, but I sometimes prefer the B-series. It's nice if, for example, you're looking for something between A4 and A5 (i.e. B5).

This video nicely explains the benefits of A4 paper and may also trigger an existential crisis:

Can't explore the scales of the Universe quite as easily with letter paper!

Is it just the size difference or is the ratio also different? I am too tired to grab my calculator.

It's the same, the difference is the starting "0" size. For the A-series, the area is 1 m^2. For the B-series, the shorter side length is 1 m. The C-series is the geometric mean of the areas of the A- and B-series.

It's sqrt(2) for all formats. As you may know, that means you can fold it in half and still have an aspect ratio of sqrt(2).
