Fun article. I liked the bit about how the size of A0 can be uniquely determined from abstract constraints. But I'm not convinced that the "Measuring Stuff" section involves anything more than memorising the exact dimensions of A4. I don't see how it applies the stuff about preserved ratios.
Nitpick: typo in the dimensions for A3.
The article declines to mention how precise paper is. The corners are very, very square and the lengths are very, very precise.
Better than an average square, better than an average ruler.
On one hand, you could do the measuring section with any standardized rectangle. On the other hand, any excuse to talk about metric paper
Letter paper, credit card, banknote, business card, etc.
