Fill every container to the last millimetre.
ContainerMath arranges your cargo, pallets and crates into balanced, high-density 3D load plans — compared across 20+ container, trailer and rail types, then exported for the team that actually loads them.
Free to start — no credit card. Your first load plan in minutes.
One cargo list, packed every way you can ship it
Everything you need to turn a dispatch list into a dense, weight-legal load plan — and prove it before you book the box.
20+ vessel types
Sea containers, trucks, trailers and rail wagons — compare capacity, internal dimensions and payload side by side.
Automatic 3D packing
Drop in a cargo list and get a dense, ordered 3D arrangement — no manual Tetris, no wasted cubic metres.
Weight & balance
Stay within payload limits and keep loads balanced front-to-back so they're road-legal and safe to move.
Crate, pallet & mixed modes
Load loose cartons, palletised goods, trolleys or a mix of all three — together in one plan.
AI manifest import
Paste a messy dispatch list and let AI turn it into structured, ready-to-pack cargo in seconds.
Clean exports
Hand the warehouse a tidy 3D/2D load plan as a PDF or image — clear stacking order, no spreadsheets.
Three steps to a loaded container
Add your cargo
Paste a dispatch list, AI-import a manifest, or add items by hand — dimensions, weight and quantity.
Pick your vessels
Choose the containers or trailers to load, and compare a few to find the densest, cheapest fit.
Get a balanced plan
ContainerMath returns a weight-aware 3D load plan with utilisation and a stacking order you can export.

Importers & distributors
Check how an order will load — and what it'll cost to ship — before you commit.
Good to know
How is this different from Carton Fit?
Carton Fit packs products into shipper cartons and cases. ContainerMath loads those boxes, pallets and cargo into shipping containers and trailers. Pro Plus includes both capabilities.
Which vessels are supported?
20+ vessel types across sea, road and rail — plus a custom vessel library on Pro plans, so you can model your own equipment exactly.
Can it handle weight limits and balance?
Yes. Plans respect each vessel's payload limit and keep the load balanced front-to-back, so what you plan is actually safe and legal to move.
Can I import a manifest?
Paste a dispatch list and AI import structures it for you. When the plan's ready, export a clean 3D/2D load plan as a PDF or image.
