For most shelves made from 3/4 inch stock, a practical span is 30 to 36 inches. Shelf depth is determined by the size of the items to be stored, generally within the range of 6 to 24 inches. Shelf depth for a general purpose bookshelf is usually 10 to 12 inches. Shelf spacing will generally range from 7 to 15 inches with 8 to 12 inches being common for bookshelves. To prevent the case from looking and being top-heavy, use a smaller shelf spacing near the top and a larger one near the bottom.
If all books were the same size and shape, bookcase and shelf planning would be simple. But that's not the case. For attractiveness as well as stability, the size and spacing of shelves depend on what you'll put on them.
