ContainerMath - 2026 Pricing, Features, Reviews & Alternatives

ContainerMath is 3D container loading and cargo-packing software that turns messy cargo lists into optimized, exportable load plans. Built on a busy export dispatch floor, it replaces spreadsheet guesswork with placement-level plans your loading crew can actually follow.

TWO SCALES, ONE ENGINE

Carton Fit packs your retail products — cartons, cans, bottles, pouches and irregular items — into your own shipper boxes and crates (dimensions in mm), returning units-per-box and boxes-needed instantly, with an optional max weight per box. Freight then arranges boxes, pallets, drums, pipes and crates into the tightest legal 3D arrangement and tells you exactly how many containers you need.

KEY CAPABILITIES

- Smart bin-packing engine: an extreme-point algorithm fits mixed box sizes, orientations and stacks, including pipe nesting.

- AI manifest import: paste a dispatch list, packing list or Excel sheet and AI parses sizes, weights and quantities in seconds — even estimating dimensions for items described by name only.

- 3D + 2D load plans: an interactive 3D placement view plus a phone-friendly 2D cross-section for the dock.

- Weight distribution & CoG: centre-of-gravity and axle-balance analysis on every plan, so loads clear the weighbridge and survey.

- Crate & trolley modes: two-level packing — fill each crate or trolley by SKU, then stack crates into the container.

- My Load Plans & profiles: reusable cargo profiles, one-click scenario presets and full plan history for repeat jobs and audits.

VESSEL COVERAGE

40+ sea, road and rail vessel types — 20ft standard, 40ft standard and high-cube, 45ft HC, reefers, open-tops, flat-racks, curtainsiders, dry vans, 53ft trailers, flatbeds, step-decks, 32ft/55ft domestic, box trucks, rail boxcars, flatcars and gondolas.

CARGO TYPES

Boxes, pallets, crates, bars and profiles, pipes and tubes, rolls and coils, drums and barrels, bottles and cans, IBC totes, sacks, big bags (FIBC) and pouches — each packed by its real geometry, orientation and stacking rules.

WHO USES IT

Manufacturers and exporters planning factory-gate dispatches; export and dispatch teams quoting container counts before production ends; logistics and freight planners and 3PLs comparing vessels for the same cargo; and project/infrastructure supply teams handling mixed boxed, crated and oversized consignments.
