What is the size of 8 k paper?

The standard size of 8k paper is 420mm x 297mm.

The original size of 8k paper is 787 x 1092(mm). The format of the paper is defined by China himself, which is inconsistent with international standards, so it is a non-standard format that has been eliminated. The commonly used a4 paper size is 2 10mm*297mm, so a piece of 8k paper is equivalent to two pieces of A4 paper.

The size of the paper layout is called folio, which is calculated by the whole paper. How many small sheets each whole piece of paper is cut into is called folio. After being folded in half, the size of the whole paper is folio, then folded in half to 4k, then folded in half to 8k, then folded in half to 16k, then folded in half to 32k, and then folded in half to 64k, and so on, and the ruler time is also reduced.

According to the size, folio is usually divided into three types: large format, medium format and small format. Taking 787× 1092 paper as an example, 12 format is large format, 16 ~ 36 format is medium format and 40 format is small format.

However, books mainly written in words are generally of medium format. The folio shapes are all rectangles with different proportions except 6-size, 12-size, 20-size, 24-size and 40-size, which are suitable for books with different properties and uses.
