Mixed or single-SKU pallets: compare workable plans
Combining products can reduce partly filled pallets, but a smaller pallet count is only useful when the resulting units remain stable and practical to handle. Compare mixed and single-SKU plans with the same quantities and the same load restrictions.
Key takeaway
Choose the arrangement that meets support, stacking and handling requirements. Better space utilization alone does not prove that a mixed pallet is suitable for shipping.
Start with the dispatch requirement
Single-SKU pallets simplify identification, counting and access to one product. Mixed pallets can be useful for small orders or several products going to the same destination. Decide whether customers accept mixed units and whether deliveries must be separated. Define these requirements before comparing pallet counts, otherwise the apparently efficient result may create sorting work at receipt.
Check support across each layer
Different carton footprints can leave steps, gaps and unsupported edges. Inspect the contact area beneath every carton instead of looking only at the top view. Keep goods within the permitted pallet footprint unless overhang has been explicitly allowed and measured. A visually neat rectangle does not establish adequate support, and gaps should not be bridged merely because a carton fits geometrically.
Respect the load each carton can carry
Record weight, allowed orientations and stacking restrictions by product. Dense, robust cartons often belong lower down, but that rule does not replace actual compression and support limits. Fragile or non-stackable goods need their own constraints. Check the load transmitted through several layers, the total cargo weight and the gross pallet weight. Unknown carton strength should trigger clarification, not an invented allowance.
Plan picking, securing and unloading
Group products so labels remain identifiable and the intended unloading sequence is possible. Consider whether removing one product leaves the remaining stack unstable. Choose wrapping, separators or other securing measures to suit the goods and transport conditions. These measures need a practical assessment; a packing calculation cannot confirm their performance merely from dimensions. Give warehouse staff a clear item list and loading order.
Compare the alternatives on equal terms
Run both plans with identical quantities, pallet dimensions, height limits and orientation rules. Compare used pallets, unused space, gross weights and the effort needed for picking and receiving. Review the placement view for collisions, support and permitted loads. A heuristic mixed-packing result is one proposed arrangement, not proof that no better arrangement exists. Keep the chosen assumptions with the released plan.
Calculate with your own data
Balance space use, carton support, stacking strength and picking order when deciding whether to combine different products on one pallet.
