What is a Barrel Fold, aka Roll Fold?

A barrel fold, also called a roll fold, is a folding style where each panel folds inward and rolls into the next, so the sheet curls in on itself like a scroll. Each panel wraps around the ones before it.

• How it rolls: panels fold in the same direction, one tucking inside the next.
• Panel sizing: the innermost panels are made slightly smaller so they nest without buckling.
• Common layout: a single sheet split into four or more panels per side.
• Great for: brochures with a clear step-by-step or sequential message.
