Are you sure ? I'm not sure we exactly know, I have seen 29.64 cm, but I think it differed in areas and in periods.
However, while we are having fun with standards, can someone explain why the length of A4 paper (European not U.S.) 29.7 cm, is identical to the Roman foot ?
A4, I believe, is German (DIN) in origin before being an international standard (ISO). It is I believe a pure coincidence that the foot and the length A4 are approximatively equal since the base of the ISO A paper size series is the A0 format whose area is 1 m². By successive division respecting the ratio of √2, you get A4 to be 297mm × 210 mm.
Coincidence, or the product of sideways thinking by some eurocrat ?
