Printed sheet is a unit for calculating the length of a publication. It is also a unit used by printing factories for pricing. A printed sheet refers to the printing of one side of a full sheet of paper, so when converted, it is half of the full sheet of paper (one pair open) and printed on both sides, it is called a printed sheet. The pricing method of calling both sides of a split sheet as one printed sheet is more commonly used. The calculation of printed sheets is of great significance in book and magazine publishing. It is the basic unit for calculating printing costs, binding costs, paper usage, and their expenses. The number of printed sheets for each specific type of book or magazine is usually calculated based on the conversion relationship between the printed sheets and the pages. A piece of paper in a book or magazine is called a "page", and there are two page numbers on both sides of a page, so one page has two sides. Under the premise of determining the page size, the number of pages on a printed sheet is equal to the number of pages, and the number of pages is half of the number of pages.

For example, after fully opening the paper and printing on both sides, one printed sheet is equal to 32 pages of 32 pages, 16 pages, or 16 pages of 16 pages, 8 pages; It can also be said that two printed sheets are 64 pages with 32 pages. Because in many situations, the expression of a page is actually the concept of a face, such as page numbers, it is best to use "face" in calculations to avoid misunderstandings.

Calculation formula for printed sheets of books and periodicals

Number of printed sheets per volume=Number of pages per volume ÷ Number of pages per volume

In practical work, the "number of pages per book" used to calculate the number of printed copies of a book refers to the total number of pages per book core, which includes not only the main text but also the number of pages occupied by auxiliary texts such as preface, table of contents, index, appendix, and postscript printed together with the main text. If the title page also uses the same paper as the main text and is printed together with the main text, it should also be included in the "number of pages per book". In short, for any book section that uses the same paper as the main text and can be printed together with the main text, the number of pages it occupies should be included in the "number of pages per book" as the basis for calculating the number of printed sheets. If there are decimals in the calculation of printed sheets, when the number of prints is relatively small (such as only printing a few thousand copies), it is generally necessary to carry up according to the principle of "making the zero pages of less than one printed sheet in a double number (occupying four pages) state" to facilitate printing and binding. For example, a 16 sheet can be printed on 0.25 sheets (4 sheets), 0.50 sheets (8 sheets), or 0.75 sheets (12 sheets), while a 3-sheet can be printed on 0.125 sheets (4 sheets), 0.25 sheets (8 sheets), 0.375 sheets (12 sheets), 0.5 sheets (16 sheets), 0.625 sheets (20 sheets), etc. However, when the print run is so large that paper costs account for about 50% of the cost of books and periodicals, this method is not suitable because the potential savings in printing and binding costs are not enough to compensate for the increase in paper costs.
