WHAT IS DESIGN FOR PRINT?//PAPER FORMATS/SERIES B//OUGD504

PAPER FORMATS/SERIES B:
The dimensions of the B series paper sizes, as defined by ISO 216, are given in the table below in both millimetres and inches (cm measurements can be obtained by dividing the mm value by 10). The B Series paper size chart to the right is a visual explanation of how the B paper sizes relate to each other.

TABLE OF PAPER SIZES FROM B0 TO B10
B SERIES PAPER SIZE TOLERANCE:
ISO 216 specifies tolerances for the production of B series paper sizes in the same way as for A series paper sizes, the specific details of which are as follows:
  • ±1.5 mm (0.06 in) for dimensions up to 150 mm (5.9 in)
  • ±2 mm (0.08 in) for lengths in the range 150 to 600 mm (5.9 to 23.6 in)
  • ±3 mm (0.12 in) for any dimension above 600 mm (23.6 in)

B SERIES PAPER SIZES DEFINITION:
The B series paper sizes are defined in ISO 216 in the following way.
The B series paper sizes were created in order to provide paper sizes that weren't covered by the A series, but also use an aspect ratio of 1:root2. B sizes are defined as size B(n) being the geometric mean of size A(n) and size A(n-1). The Geometric Means of 2 numbers being the square root of the product of the two numbers.
