Calculation of spine width is crucial while designing a book cover. We do not want spine to be too narrow or too wide. The spine width of a book depends on the paper-weight (GSM), quality of paper and number of pages. Type of cover also adds to the spine width. A book may be paperback, hardcover or hardcover with dustjacket.
This tool calculates spine width based on the paper/pages input given by you. Please note that this spine measurement is approximate.
