German Extension

The German standard DIN 476 was published in 1922 and is the precursor of the current ISO standard A, B and C series’ of paper sizes. It differs in two details from its international successor: DIN 476 provides an extension to formats larger than A0, denoted by a prefix factor. In particular, it lists the formats 2A0 – which is twice the area of A0, and 4A0 – which is four times the area of A0. This series also has slightly different tolerances from the ISO standards.
