How can a bookcase be made most practical?

To make a bookcase practical, first be clear about what books you will store and how many. Adjustable shelves are recommended; do not fix the shelf heights so that both large art books and ordinary books can be accommodated. Keep the depth at around 300 mm; too deep wastes space. Combine open compartments with cabinets with doors: keep frequently used books open and hide miscellaneous items. If the budget is limited, mainstream configurations (overall reference range) are 400–800 yuan/㎡ in Beijing and 340–680 yuan/㎡ in Baoding, Langfang, Xiong'an and Zhuozhou. To see edge banding and side-hole workmanship, you can book a visit to the Gaobeidian factory to observe cutting, edge banding, and side-hole processes. The following are reference prices and do not constitute a formal quotation; the actual price must be calculated based on dimensions, design, materials, hardware, quantity, and site conditions.
