History

The size of a sheet of paper is changed over time. At first she was completely arbitrary and hung depending on the age of the size of the scoop shape from.

Since 1883 efforts have been made in Germany to unify the sheet sizes. It emerged 12 normal formats, of which the number one unbroken or plano measured in 33x42 cm.

Finally, one developed in 1922 until today standard paper format DIN A series in which the format is the eighth A5 sheet ( octave ) and produced by triple folding the single sheet (A2).
