Which is bigger, 9k or 8k paper?

9k and 8k paper are a little bigger than 8K paper.

8k means cutting a piece of paper into 8 pieces, and the size of 8k paper is 420mm*285mm.

The size of 9k paper is 260mm×362mm, which is a little larger than 8k paper.

There are 4000 sheets of eight sheets of paper in a ream and 4500 sheets of nine sheets of paper in a ream.

Paper size standard

The specification of paper refers to that after paper is made, it is trimmed and cut into a certain size. In the past, the size of paper was expressed by the number of "open" (for example, 8 open or 16 open, etc. ). At present, China adopts international standards, which stipulate that the format specifications of paper should be represented by A0, A 1, A2, B 1, B2 and other marks. The standard stipulates that 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 layout size of A0 is 841mm×1189mm, and the layout area is 1m2.

B0 has a width of1000 mm×1414 mm, and its width area is1.4m2. C0 has a width of 9 17mm× 1297mm, and its width area is/kloc-. The format specification of copy paper only adopts A series and B series.

If A0 paper is divided into two halves along the length, it becomes A 1 specification; If A 1 paper is split along the length, it becomes A2 specification, and so on, it becomes A8 specification; According to this method, B0 paper is also split into B8 standard. The following table lists the format sizes of A0 ~ A8 and B0 ~ B8. 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, while Group C is mainly used for envelopes.

In addition, there are many nonstandard sizes in China, such as the business acceptance registration form used by China Mobile and other companies, which is 190mm*265mm, so it is easy to make mistakes when the copier automatically selects paper.
