In order to meet the basic functions, the size of the bookcase is generally about 300mm in depth and about 2200mm in height (beyond this height, ladders are generally needed for auxiliary use). The grid height should be at least 300mm( 16 opening height, and only 150mm for audio-visual discs). Depending on the material, the width of the grid is limited. Use particleboard or density board with a thickness of 18mm, and the limit width of the grid shall not exceed 800 mm (the limit width of the board with a thickness of 25 mm is 900mm). Use solid wood grid, and the limit width is generally1200 mm.

The height of the bookcase partition should not be less than 220 mm, the height of the partition interlayer is generally 300-350 mm, the magazine width is 25cm, and the book width is 15cm. The vertical board of bookcase is generally 350㎜~ 800㎜, and the normal height of the board is 350 ㎜ ~ 400 ㎜; Personalized design is generally 32 books with a height of 250㎜, and 16 books with a height of 320㎜.

The bookshelf has a depth of 250-400 mm (each cell), a length of 600- 1200 mm, a bottom depth of 350-450 mm and a height of 800-900 mm. ..

If the linear width of the whole bookcase is more than 4 meters and the height is more than 2.2 meters, this design will give people a simple, broad and vast momentum and feeling. Under this style of design, the four corners of the lattice can be decorated with ancient wood carvings, and it will also create an elegant and noble impression on bookcases (also known as bookshelves or whole bookcases) (the Forbidden City has classic works of this design).

Different styles of bookcases have different requirements for size. The styles of bookcases are divided into one-shaped, L-shaped and U-shaped. A straight line means that the bookcases are lined up against the wall. There is an angle between the two sides of the L-shaped bookcase against the wall, and the U-shaped bookcase is a combination of three straight lines and two angles. This kind of bookcase needs space, and it looks good in a large study. In terms of size, the size of a single bookcase on the market is above 80 cm, the thickness is between 30 and 40 cm, and the height is about 1.8-2.2 meters. Although there is little difference in size, if the functions emphasized are different, these sizes are still very particular.
