Cover Spine Width
Paper type affects spine width
Spine width values differ across different paper types. Each paper type has a different sheet thickness, which changes the total spine width at the same page count. For some paper types, spine widths also differ by bleed type (Full Bleed vs. No Bleed). Ensure your integration passes the correct paper type when calculating spine dimensions. Select the appropriate options below to view the corresponding spine width table.
