Exactly. The DIN A series (0 to 7, i think) is from the 1920ies.
Very smart for graphic designers, you always have the same proportion.
A0 is the big poster, A2 is the small poster, A4 is a flyer and A6 is
the common format of a postcard.
And you can easily calculate the weight of a paper or a flyer,
because the paper is given in g/m©÷.
Very german. Based on a french idea of the times of the revolution,
the meter system.
With the roman foot, i think it is coincidence.
I heard the roman foot was 29,63 cm.
