The library is a place with a lot of books, so the role of bookshelves in the library is obvious. Bookshelves in libraries can be divided into single-sided bookshelves and double-sided bookshelves according to types. Among them, the number of double-sided bookshelves is obviously more than that of single-sided bookshelves, which can save space and increase the available space of the library. The size of single-sided bookshelf is 90×35×220cm, and the size of double-sided bookshelf is 90×50×220cm. However, due to the different spatial layout and functional requirements of different libraries, the size of bookshelves is also different, and they tend to customize bookshelves, so bookshelves can be the most suitable bookshelf size.

There are also common library bookshelves, size: 900 × 450 × 2000 mm; ; Where 900 is the section length; 450 is the section width; 2000 is the height of the bookshelf. In the process of customization, the size of the bookshelf mainly changes in height, ranging from 2 meters to 2 meters.

In fact, the size of the bookshelves in a library depends on the size of the books, because books in different periods have different requirements on the size, for example, some books are 16 open and some books are 32 open, so there are different requirements on the size of the bookshelves, so as to maximize the use of space.
