  • Area of A0 = 1m^2
  • A0/A1 = A1/A2 = A2/A3 = A3/A4 … A9/A10 = 2
  • Length = √2 * Width

The area of B series sheets is the geometric mean of successive A series sheets. B1 is between A0 and A1 in size, with an area of 0.707 m2 (​1⁄√2 m2). As a result, B0 is 1 metre wide, and other sizes of the series are a half, a quarter or further fractions of a metre wide.

  • B5 is a relatively common choice for books
  • B7 is equal to the passport size ID-3 from ISO/IEC 7810
