Container Loading Calculator
Calculate geometric carton capacity for standard or custom containers — including rotations, door clearance and payload.
Mixed SKUs and reusable shipping projects.
The free single-SKU container optimizer stays available. Multi-product loading, CSV import and exports are planned at €6.99/month.
How the container loading calculator works
PackMize generates all box orientations allowed by the selected rotation axes, builds efficient two-dimensional layer patterns for each feasible layer height, and then chooses a height combination that maximizes the number of boxes inside the container. Payload and requested quantity are applied after geometric capacity.
Container dimensions are not universal
Internal and door dimensions can vary slightly by container manufacturer, owner and equipment series. PackMize therefore treats its presets as representative planning dimensions and exposes a custom-container option for operational use.
Limitations
The V1 models rigid rectangular cartons. It does not model loading sequence, axle loads, center of gravity, lashing, crush strength, pallets inside containers, dangerous goods segregation or real forklift access. A geometric plan is not a transport-safety approval.
Frequently asked questions
Does the container calculator use cubic metres only?
No. It builds geometric layers from the carton dimensions and tests allowed orientations before applying payload limits.
Are standard container dimensions exact for every carrier?
No. Published internal and door dimensions can vary by manufacturer and equipment. PackMize presets are representative and can be replaced with custom dimensions.
Can I load multiple product sizes?
The V1 optimizes one rectangular SKU at a time. Mixed-SKU loading is planned for PackMize Pro.
