Cartora: Box & Pallet Planner

Cartora is an offline packaging studio that helps you design the right box, plan pallet loads and estimate shipping weight — all from your phone, with no account needed. Whether you run a small online shop, manage a warehouse or design product packaging, Cartora turns packaging math into clear, visual answers. BOX CALCULATOR Enter inner dimensions and wall type to get outer size, volume, surface area and the board you need. Rotate a live 3D preview of your box. DIELINE GENERATOR Create flat box templates for regular slotted cartons, tuck-end boxes, mailers, trays and more. Cut and fold lines are drawn to scale and can be exported as a printable PDF. PALLET PLANNER Choose a pallet size, height and load limit. Cartora finds the best box orientation and shows boxes per layer, number of layers, space utilization and total weight. DIMENSIONAL WEIGHT Compare actual and dimensional weight with common divisors and see which one is billable before you ship. CARTON STRENGTH Estimate box compression strength from board grade and box size, then check a safe stacking height with humidity and storage factors. CUSHION AND VOID FILL Work out empty space inside a box and estimate how much paper, air pillows or foam you need. PACKAGING COST ESTIMATOR Add board, print, labor and fill costs to see unit and batch cost at different quantities. PACKING LISTS AND LABELS Build packing lists, assign items to boxes, and design printable shipping labels with handling symbols and box counts.
