Mixed-SKU pallet planning is harder than a one-box pallet calculator because several carton sizes compete for the same footprint, height and weight capacity. This planner accepts multiple SKU rows and estimates how the mix can be distributed across pallets.
How to use this calculator
Set the pallet dimensions, pallet/packaging tare, height and gross-weight limits, then add carton types with dimensions, quantity and weight. The planner allows base rotation and applies a greedy shelf-and-layer heuristic to the carton list.
Formula and method
The algorithm sorts larger and taller cartons first, fills shelf rows inside each layer, starts new layers when needed and starts a new pallet when the current pallet cannot accept the next carton within the entered geometry and gross-weight limits after tare is included.
Worked example
A mixed shipment with three carton sizes may use pallet space more efficiently than treating every SKU as a separate pallet, but the exact gain depends on the dimensions and sequence. The planner provides a repeatable scenario estimate rather than a hand calculation.
What to check before you ship
This is not an exact three-dimensional optimization proof. Mixed-SKU stacking must also respect crush strength, stack compatibility, center of gravity, pallet tare, labeling, pick sequence and customer or warehouse rules.
Why the result matters
Accurate dimensions and weights help with quoting, space planning and avoiding preventable adjustments. Always use the packaged outside dimensions that will actually be tendered for transport, and verify any carrier-specific rules that affect billing or classification.
The mixed-SKU pallet planning guide explains why a layout estimate still needs stability and weight checks. Use the pallet weight calculator for a separate mass check.
