- Everyone uses them each day, but nobody knows the sizes, so here is a
- list for the USENET community. Please proof read it, before I'll include
- it in the standards FAQ.

- International paper formats
- ---------------------------
-
- The paper end formats defined by ISO in the A, B and C series are used
- today in nearly all countries apart from North America.
-
- The formats have been determined according to the following rules:
-
- - A0 has an area of one square meter.
- - The format of all members of the A, B and C series is 1 : sqrt(2).
- - You get the next higher format by cutting the paper in two
- equal pieces parallel to the shorter side. This results again in
- an 1 : sqrt(2) format (that's the big advantage of this format).
- - The size of a B paper is the geometric mean between the size of
- the corresponding A paper and the next bigger A paper. E.g.
- B1 is between A1 and A0.
- - The size of a C paper is the geometric mean between the size of
- the A and B paper with the same number.
-
- The following table lists the paper sizes rounded to an integral number
- of millimeters, which is the official definition:
-
- 4 A0 1682 x 2378
- 2 A0 1189 x 1682
- A0 841 x 1189 B0 1000 x 1414 C0 917 x 1297
- A1 594 x 841 B1 707 x 1000 C1 648 x 917
- A2 420 x 594 B2 500 x 707 C2 458 x 648
- A3 297 x 420 B3 353 x 500 C3 324 x 458
- A4 210 x 297 B4 250 x 353 C4 229 x 324
- A5 148 x 210 B5 176 x 250 C5 162 x 229
- A6 105 x 148 B6 125 x 176 C6 114 x 162
- A7 74 x 105 B7 88 x 125 C7 81 x 114
- A8 52 x 74 B8 62 x 88 C8 57 x 81
- A9 37 x 52 B9 44 x 62 C9 40 x 57
- A10 26 x 37 B10 31 x 44 C10 28 x 40
-
- The most popular sizes are perhaps:
-
- A0 technical drawings
- A4 letters, magazines, documents
- A5 books
- C4,C5,C6 envelopes
- B4,A3 supported by many copy machines, newspapers
-
- There are also stripe formats possible, e.g.
-
- 1/3 A4 99 x 210
- 2/3 A4 198 x 210
- 1/4 A4 74 x 210
- 1/8 A4 37 x 210
- 1/4 A3 105 x 297
- 1/3 A5 70 x 148
- etc.
-
- (The values have been copied from DIN 476 (Dec 1976) which is the German
- version of the ISO standard).
