Use this tool to calculate the precise dimensions of your cover's spine. Accurate spine width is needed to create a print-ready PDF of your cover.
Please review our cover PDF checklist for complete instructions for how to setup your cover PDF for printing.
Your book's spine text should read from top to bottom. For example, if your book has both a main title and subtitle, the main title should appear at the top of the spine. Common spine elements to add after the book title include author name, publisher name or publisher logo.
Text should be centered horizontally along the width of the spine and have a minimum gap of 1/16 inches between it and each edge of the spine. This gap prevents your spine content from accidentally appearing on the front or back of your cover. Books with a spine width of less than 0.15 inches do not usually have text on them for this reason.
