What do Quarto and Folio mean?
Quarto and folio are printers' terms used to describe oversized books.
- Up to 27 cm. (approx. 10.5") is the height range for most books.
- A Quarto book has a height of 27-31 cm. (approx. 10.5 - 12.25").
- A Folio book is over 31 cm. (12.25").
Libraries add quarto or folio height designations to call numbers because sometimes libraries or collections must file oversized books separately to conserve shelving space. Different locations may vary slightly in their specifications. If you can't find the book you're looking for on the shelf, be sure to ask a library staff member. The size of the book can affect its location.
