How this calculator works
Cartons per layer use the better of two right-angle orientations. Capacity is limited by height and, when entered, maximum gross pallet weight.
Using this result
Capacity is constrained by the simple right-angle carton grid, stack height and any gross-weight limit entered.
Next step: Check carton strength, overhang rules, pallet tare weight and handling limits before building the load.
Worked example
On a 120 × 100 cm pallet, a 40 × 30 × 25 cm carton fits 10 per simple layer and 6 layers high: 60 cartons.
How to measure
- Use usable deck dimensions, not nominal overhang.
- Measure compressed, closed cartons.
- Set height to the permitted loaded-goods height.
Common mistakes
- Treating this simple grid as optimized mixed-case packing.
- Ignoring pallet weight.
- Exceeding carton compression or facility height limits.
