Hallo Hans! As I defined a few envelope formats I realized that some predefined paper sizes differ from my DIN copies. DIN 476, Dez 1976 DIN 476 Part 1, Feb 1991 (A/B variants) DIN 476 Part 2, Feb 1991 (C variants) differ (1mm) B3: 353x500 % width*height B4: 250x353 B5: 176x250 B6: 125x176 B8: 62x88 B9: 44x62 C1: 648x917 C2: 458x648 C3: 324x458 C6: 114x162 C7: 81x114 missing 4 A0: 1682x2378 2 A0: 1189x1682 A10: 26x37 B10: 31x34 C10: 28x40 DIN 678-1, Jan 1998 DIN 680, Jan 1995 switched DL: 110x220 missing C6/C5: 114x229 E4: 280x400 That's all :) If you are interested, I can mail you copies of this boring DIN stuff.
