Published on 18 August 1922, the German standard DIN 476 is the original specification of the A, B and C paper sizes. In 1991, it was split into DIN 476-1 for the A and B formats and 476-2 for the C series. The former has been withdrawn in 2002 in favor of adopting the international standard as DIN EN ISO 216, but part 2 has been retained and was last updated in 2008. The first and the second editions of DIN 476 from 1922 and 1925 also included a D series.
