Pallet, container & cutting optimization.
Free calculators for quick jobs. A professional workspace for real orders, mixed-SKU loads, reusable scenarios and auditable load plans.
One-off calculation or repeatable workflow.
Start with a free calculator when the job is simple. Move to the Load Planner when the order contains multiple products, constraints or decisions.
Pallet optimization
How many cartons fit? Calculate TI-HI, height, payload and the tested layout.
Open Pallet Calculator → Free calculatorContainer loading
Test 20 ft, 40 ft and High Cube capacity with real carton geometry and payload limits.
Open Container Calculator → Professional workflowMixed-SKU load planning
Import real orders, optimize mixed pallets, containers or vehicles, compare scenarios and save the chosen plan.
Explore Multi-SKU Load Planner → Free calculatorsMaterial optimization
Arrange sheet parts or linear cuts with kerf-aware plans and transparent utilization metrics.
Open cutting tools →Know what fits before you load or cut.
Use millimetres, centimetres, metres, inches or feet. Review capacity, useful material and the constraints that limit the result.
Enter the real inputs
Choose standard equipment or add your own dimensions, products, material sizes and required quantities.
Apply the constraints
Model height, payload, rotation, kerf, support, stop order and other constraints relevant to the selected tool.
Inspect the evidence
Review the visual plan, utilization, limiting constraints and whether the mathematical bound was actually reached.
Single SKU when the job is simple. Multi-SKU when it is real.
Use the public calculators for a quick capacity check or move into a persistent workspace for complete orders and repeatable planning.
Turn a cut list into a material plan.
Compare layouts for rectangular panels or lengths of timber, metal profiles, bars and pipes with explicit kerf and utilization.
A good layout is not automatically a proven optimum.
PROVEN OPTIMAL means the result reaches a valid mathematical bound, or a completed exact search proves the minimum within the stated model. BEST SOLUTION FOUND means the engine found this plan without proving that no better one exists.
Packing results are geometric planning estimates. General sheet layouts are rectangular arrangements; when an ordered guillotine sequence is required, use the dedicated Guillotine mode. No cutting result is a CNC toolpath, so check actual material and machine constraints before use.
Specific questions with reproducible answers.
PackMize publishes the assumptions, formulas and worked examples behind the tools so both people and machines can understand what a result means and reproduce it.
Turn a calculator result into a repeatable operation.
Reuse SKUs, build projects, optimize mixed loads, compare scenarios, save auditable snapshots, generate Professional Load Reports and share read-only plans. The four core calculators stay free.
