International standard paper:

Specify A0, A 1, A2, B 1, B2 ... and other marks to indicate the paper format specifications. According to the standard, the proportional relationship between the width (represented by X) and the length (represented by Y) of paper is X: Y =1:N. ..

According to the basic area of paper format, the format specifications are divided into A series, B series and C series.

The folio size of A0 is 841mm×1189mm, and the folio area is1m2;

B0 has a width of1000 mm×1414 mm and a width area of √ 2m2;

The width dimension of C0 is 9 17mm× 1297mm, and the width area is1.2m2; The format specification of copy paper only adopts A series and B series.

If A0 paper is split in half along the length direction, it becomes A 1 specification; If A 1 paper is split along the length direction, it becomes A2 specification, and so on, it becomes A8 specification; B0 paper is also divided into B8 standard according to this method.

The format sizes of A0 ~ A8 and B0 ~ B8 are shown in the following table. Among them, A3, A4, A5, A6, B4, B5 and B6 are common specifications of copy paper.

Many countries use the international standard ISO 2 16 to define the paper size. This standard originated in Germany and was adopted in 1922. It defines three groups of paper sizes: A, B and C, including the well-known A4 paper size. Group C is mainly used for envelopes.
