Area of A0 = 1 Square meter
A0/A1 = AI/A2 = A2/A3 ...........A9/A10 = 2
Length = 1.414 * Width

Width of An = 2^(-1/4-n/2) and Height = 2^(1/4-n/2)


Area of B0 = 1.414 Square meter
B0/B1 = B1/B2 = B2/B3 ............B9/B10 = 2
B0/A0 = B1/A1 = B2/A2 ..........B10/A10

Width of Bn = 2^(-n/2) and Height = 2^(1/2-n/2)

The C series is used for folders, post cards and envelopes. C series envelope is suitable to insert A series sizes.

Width of Cn = 2^(-1/8-n/2) and Height = 2^(3/8-n/2)

The allowed tolerances are ±1.5 mm for dimensions up to 150 mm, ±2 mm for dimensions above 150 mm up to 600 mm, and ±3 mm for dimensions above 600 mm.

The A, B & C series are trimmed paper sizes. ISO also define format series RA and SRA for untrimmed raw paper, where SRA stands for 'supplementary raw format A'. These formats are only slightly larger than the corresponding A series formats. Sheets in these formats are  cut to the end format after binding. The ISO RA0 format has an area of 1.05 m2 and the ISO SRA0 format has an area of 1.15 m2. These formats also follow the sqrt(2)-ratio and half-area rule, but the dimensions of the start format have been rounded to the full centimeter. The common untrimmed paper formats that printers order from the paper manufacturers are

RA SERIES mm × mm Inch × Inch SRA SERIES mm × mm Inch × Inch
RA0 860×1220 33.86×48.03 SRA0 900×1280 35.43 × 50.39

Japanese Paper Sizes

Japan has adopted the ISO series A sizes, but its series B sizes are slightly different. These sizes are sometimes called JIS B or JB sizes.

A JB0 sheet has an area of 1.5 square meters. The area of each size is the arithmetic average of the areas of the A series page with the same number and the A series page with the next higher number. So for example, the area of a JB4 page is the average of the area of an A4 sheet and an A5 sheet. (In the ISO B series, the area of each sheet is the geometric mean of the A sizes, that is, the square root of the sum of their areas.)

JB SERIES mm × mm Inch × Inch JB SERIES mm × mm Inch × Inch
JB0 1030×1456 40.55×57.32 JB6 128×182 5.06×7.17
JB1 728×1030 28.66×40.55 JB7 91×128 3.59×5.06
JB2 515×728 20.27×28.66 JB8 64×91 2.53×3.59
JB3 364×515 14.33×20.27 JB9 45×64 1.8×2.53
JB4 257×364 10.13×14.33 JB10 32×45 1.27×1.8
JB5 182×257 7.17×10.13

The United States, Canada, and in part Mexico, are today the only industrialized nations in which the ISO standard paper sizes are not yet widely used.
