Common brochure sizes include A4 and US Letter formats, used for both bi-fold and tri-fold layouts.

Tri-fold brochures typically use A4 or US Letter flat sizes, divided into three vertical panels.

A bi-fold brochure folds once into two panels, while a tri-fold brochure folds twice into three panels.

Incorrect sizes cause panels to misalign, overlap, or be cut off after folding.

Misalignment usually happens when panels aren’t sized correctly, or margins don’t account for folds.

Brochures are printed flat on standard sheets before being folded.

Choose based on how much content you need and how the brochure will be folded.

Plan panel widths carefully and keep content away from fold lines.

Resize to the flat brochure size and avoid stretching individual panels.
