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.
Usually shelves are available in widths of 6, 8, 10 or 12 inches (although you can cut your own shelves of plywood or lumber if you wish). Stock shelves are factory-finished to blend in with the pilasters and brackets and are usually available in 24-, 30-, 36- and 48-inch lengths.
