What is "quarto"?

Quarto is a book format created by folding a large sheet of paper twice to produce four equal leaves, resulting in eight pages per sheet. This format is larger than octavo but smaller than folio. Quarto books typically measure about 9.5 inches by 12 inches, which is approximately 240 mm by 305 mm. This size is often used for academic texts, art books, and other publications where a larger page size is beneficial for detailed information or illustrations.
