ISO 216 does not define sizes larger than A0 or B0. With the German standard DIN 476 "Trimmed sizes of paper" the sizes can be expanded by using a factor in front of the size:
Oversized sheets are used when it is desirable to give extra protection to the drawing sheets by providing a binding or trimming margin.
ISO A Series | Size (mm) |
---|---|
RA0 | 860 x 1220 |
RA1 | 610 x 860 |
RA2 | 430 x 610 |
RA3 | 305 x 430 |
RA4 | 215 x 305 |
RA5 | 153 x 215 |
The ISO B series are geometric means between the A series and defined to satisfy the requirements of sizes between the A series sizes. For example, B1 is a geometric mean between A1 and A0.
ISO B Series | Size | |
---|---|---|
(mm) | (inches) | |
B0 | 1000 x 1414 | 39.37 x 55.67 |
B1 | 707 x 1000 | 27.83 x 39.37 |
B2 | 500 x 707 | 19.68 x 27.83 |
B3 | 353 x 500 | 13.90 x 19.68 |
B4 | 250 x 353 | 9.84 x 13.90 |
B5 | 176 x 250 | 6.93 x 9.84 |
B6 | 125 x 176 | |
B7 | 88 x 125 | |
B8 | 62 x 88 | |
B9 | 44 x 62 | |
B10 | 31 x 44 | |
B11 | 22 x 31 | |
B12 | 15 x 22 |
Series C is primarily used for envelopes. The C series formats are geometric means between the B series format with the same number and the A series format with the same number - C2 is the geometric mean between B2 and A2.
ISO C Series Envelopes | Size | |
---|---|---|
(mm) | (inches) | |
C0 | 917 x 1297 | 36.00 x 51.20 |
C1 | 648 x 917 | 25.60 x 36.00 |
C2 | 458 x 648 | 18.00 x 25.60 |
C3 | 324 x 458 | 12.80 x 18.00 |
C4 | 229 x 324 | 9.00 x 12.80 |
C5 | 162 x 229 | 6.40 x 9.0 |
C6 | 114 x 162 | |
C7 | 81 x 114 | |
C8 | 57 x 81 | Commonly Used Formats |
An A4 page will fit into a C4 envelope, A5 will fit into a C5 envelope and so on.
