From product-in-a-carton to a full container
Generic cube calculators treat everything the same. ContainerMath works at both scales — Carton Fit packs your products into the right carton or crate, and Freight stacks, nests, crates and balances real cargo into the right number of containers.
Carton Fit for FMCG
Pack your products into your own cartons and crates (sizes in mm) and get units-per-box and boxes-needed instantly — with an optional max weight per box.
3D + 2D load plans
Interactive 3D placement view plus a 2D cross-section your loading crew can read on a phone at the dock.
Smart bin-packing engine
An extreme-point algorithm fits mixed box sizes, stacks and orientations into the tightest legal arrangement — including pipe nesting when you need it.
Crate & trolley modes
Two-level packing: fill each crate or trolley by SKU first, then stack the crates into the container for the real-world load.
AI manifest import
Paste a dispatch list, packing list or Excel sheet — AI parses sizes, weights and quantities in seconds.
Weight distribution & CoG
Centre-of-gravity and axle-balance analysis on every plan, so loads pass weighbridge and survey without surprises.
Saved plans & profiles
Reusable cargo profiles, one-click scenario presets and a full history of plans for repeat jobs and audits.
Paste the mess. Get a clean manifest.
Drop in a dispatch list, a packing list, or an Excel paste. The AI reads sizes, weights and quantities — even estimating dimensions for items described only by name — and hands back structured cargo lines ready to pack.
The same engine, every kind of load
From a wall of identical cartons to a 20-footer of boxes, drums and a machine crate — here are three live load plans, each packed and balanced its own way.
From dispatch list to load plan in three steps
Paste your manifest
Drop in a dispatch list, packing list or Excel sheet — or enter items by hand. AI fills in dimensions and weights.
Pick your vessel
20 container, trailer and rail wagon types, from a 20ft standard box to a 55ft domestic double-deck.
Get the load plan
A packed 3D plan with stacking, crate fill, weight balance and the exact number of containers you need.
If it ships in a container, it packs here
Boxes, cylinders and flexible loads — each packed by its real geometry, orientation and stacking rules.
Down to the last retail unit
Carton Fit packs your products — cartons, cans, bottles, pouches and odd shapes — into the right shipper box or case, then tells you units-per-box and boxes needed.
One cargo list, compared across every way to ship it
Tap any two or more to see capacity, internal dimensions and payload side by side.
Built for the people who actually load containers
ContainerMath grew out of real export jobs on a busy dispatch floor — the workflows are the ones loading teams already use.
Manufacturers & exporters
Producers planning factory-gate dispatches and export containers for boxed, palletised and profile cargo.
Export & dispatch teams
Quote container counts to customers before production ends — not after the first truck is half-loaded.
Logistics & freight planners
Forwarders and 3PLs comparing 20ft, 40ft HC, domestic 32/55ft, trailers and rail wagons for the same cargo.
Project & infrastructure supply
Teams supplying construction and utility projects with mixed boxed, crated and oversized consignments.
