Frequently Asked Questions
Common questions regarding book spine thickness calculators and cover prepress.
Q.How is book spine thickness calculated?
The thickness is calculated by multiplying the page count of the book block by the caliper thickness of the selected paper stock, adding board wrap hinges for hardcovers.
Q.What is paper caliper?
Caliper is the thickness of a single sheet of paper, usually measured in thousandths of an inch or microns. PPI (Pages Per Inch) determines how many pages make up one inch of thickness.
Q.Why should I include bleed margins?
Bleed margins (usually 0.125 inches or 3.175mm) ensure that the background color extends beyond the trim line. When the cover is cut or wrapped around the binder boards, this prevents white edges.
Q.Are my book titles or designs saved online?
No, all graphics, dimensions, and PDF compilation codes are computed locally in your browser memory. Your intellectual property remains entirely offline.
