Determining the weight capacity of a bookshelf involves considering its design, materials, and construction. Typically, standard bookshelves can support 20-25 pounds per shelf. However, it is crucial to consult the manufacturer's guidelines for precise weight limits. Distributing weight evenly across the shelves prevents strain. Creative arranging, such as interspersing decorative items, not only enhances visual appeal but also helps in maintaining the longevity and load-bearing capacity of the bookshelf.
