How do I choose the right number of bookshelves for my office?

Estimate your storage needs: a standard 36 in. wide shelf holds approximately 30–40 standard binders or 40–50 average hardcover books. For every 100 binders or 150 books you need to store, plan for approximately 3 standard 36 in. shelves. Add 20% capacity buffer for growth.
