Roll Fold Panel Calculator
Enter flat width, panel count and the narrower inside-panel allowance required by your finisher. The result returns panel widths and score positions.
Enter your job values
Use the real values from your job. Optional fields can stay blank; zero should only be used when the value genuinely does not apply.

Paper bulk, grain and equipment can change the geometry
Booklet creep, fold compensation and spine thickness are physical-production estimates. Whenever a fold, bind, die or laminator controls the finished piece, record the actual stock caliper and the equipment/vendor specification rather than converting GSM to thickness by assumption.
What the result is useful for
A compensated layout helps prevent a tucked panel from colliding or buckling when the brochure wraps around itself.
How the calculation works
The innermost panel is reduced by the entered compensation; the remaining width is distributed across the other panels, then cumulative widths become score positions.
What this calculator cannot know
Actual fold compensation depends on stock caliper, grain, fold sequence and equipment. Use the finishing provider’s specification and proof the fold.
