External dimensions of bookshelves
Bookcase width dimension: The width dimension of bookcase varies according to the number of bookcase doors. Generally, the width of two bookcases is between 500 and 650 mm, and the width of three or four bookcases is expanded to 1/2 to 1 times. The size and width of some special corner bookcases and large bookcases can reach 1000~2000mm, or even wider. But now the whole bookcase is custom-made furniture, and the width can be customized according to the actual needs of consumers.
Height dimension of bookcase: The height dimension of bookcase should be the highest at the top of bookcase until adults can reach the books on the top partition. If the book falls too high, it is easy to cause security risks and it is not convenient to take the book. Second, it will affect the center of gravity of the bookcase, causing security risks and affecting the stability of the bookcase. Take two bookcases for example. Generally, the height of bookcase is 1200mm to 2 100mm. If the height exceeds this size, ladders are generally needed to assist in holding books, which affects practicality. But if it is a top-level bookcase with a particularly large collection space in the library, the height of the bookcase can be as high as 3000 mm
Internal dimensions of bookshelves
Depth dimension of bookcase bookcase: The main purpose of bookcase is to collect and place books, so the depth dimension of bookcase can be based on the current general book specifications. At present, the scale of books, even literary books, is not very large. Therefore, the standard of the depth dimension design of modern bookcases between 280 mm and 350 mm can not only meet the collection needs of most modern people.
Height dimension of partition: The height dimension of partition is also designed according to the specifications of books. For example, the height of bookcase partition is designed according to the size standard of 16 format, the height of laminated board is between 280 mm and 300 mm, while the height of partition designed according to the standard of 32 format is between 240 mm and 260 mm. Some books with relatively large specifications that are not commonly used are usually above 300 mm to 400 mm, and the fitting height can be set at 300 mm to 400 mm.
Other dimensions of bookcase: The height dimension of bookcase drawers is usually between 200mm~350mm. When customizing bookcases, there are width dimensions between bookcases. For a normal two-door bookcase, the limit width of the compartment should not exceed 800mm; for a four-door or wider bookcase, the width of the compartment is generally 1200mm. If the width of the bookcase is unreasonable, it will cause the instability of the bookcase and easily lead to problems in the use process.
Customization precautions
edit
Most customized bookcases in the market use MDF, and some use moisture-proof boards, which are better than MDF. Open and close the cupboard door to see if it is smooth. If there is a creaking sound, you'd better not buy it.
Books are relatively heavy, which is different from other items stored in furniture, so the requirements for firmness are very high, especially the horizontal plate in the middle, and the vertical support is relatively firm, so that the whole can be firm and durable.
The formaldehyde content in the materials of cupboard doors or cabinets is too high, which will have adverse effects on the health of users. How to judge its formaldehyde content exceeds the standard? The simple way is to open the cupboard door and open the drawer. If it exceeds the standard, it will generally emit a strong pungent smell and even make people cry. This situation shows that the formaldehyde content in this bookcase is seriously exceeding the standard. This kind of bookcase is very harmful to health, so it is generally not recommended to buy it.
Some bookcases are particularly cheap, and sometimes they can even be cut down to thousands of dollars. In fact, most of these bookcases are made of a large number of low-quality and low-priced materials, which often exceed treasures. Consumers should be careful of these seemingly cheap ones. In addition, all bookcases made of wood-based panels have strict restrictions on edge sealing, especially particleboard, which can limit the release of harmful substances in wood-based panels, but many manufacturers only do partial edge sealing in order to save materials, so it is best not to buy this kind of bookcase.
