01Compare both grid orientations
The free calculator checks cartons placed lengthwise and widthwise across the pallet. A 120 × 80 cm pallet and 40 × 30 cm cartons produce 6 cartons in one uniform grid and 8 in the other. Mixed-orientation patterns may produce different results.
02Understand TI and HI
TI is the number of cartons per layer; HI is the number of layers. Multiply the two to estimate cartons per pallet. With 25 cm carton height and 100 cm of cargo height, the geometric example gives 4 full layers: 8 × 4 = 32 cartons.
03Separate geometry from stackability
A carton that fits geometrically may not support the cartons above it. Check compression strength, pallet capacity, load stability and handling requirements. The calculator does not assess whether a particular load is safe to stack.
