Fold Trim Calculator

Fold Layout is an offline tool designed for paper folding, trimming, and booklet making. Choose common paper sizes or enter custom dimensions, then set fold type, page count, bleed, margins, binding method, and trimming loss. The app automatically calculates each panel width, flat size, cut line positions, and final finished size. It is useful for making journal inserts, greeting cards, table tents, folded flyers, manuals, booklets, labels, and handmade paper projects. All data is stored only on your device.
