A4: the most rational/irrational ratio-sized paper size

submitted by pierrekrahn

An explanation as to how the A4 paper got its measurements.

It's a rational reason based on an irrational number.

Interesting, but I think it needed to touch on the idea that A0 is not 1 square meter in the sense of 1m x 1m, but rather it has an area of 1m squared with the A aspect ratio of 1 / sqrt(2).

The graphic doodles animating during the talk show A0 as 1m x 1m, which would blow the whole aspect ratio quality right out of the water.

--EDIT-- Did a wikipedia search and came up with a handy chart HERE.

Could have been half as long - He had a good start, then just started to ramble...
