Pallet Height Optimizer
Find how many carton layers fit within a height limit once the pallet's own base height is accounted for, and the resulting total pallet height.
6 inch pallet base plus 5 layers at 10 inches each totals 56 inches, 86.2% of the 65 inch limit. A calculation that skips subtracting the pallet base height would claim 6 layers, overflowing the limit by 1 inches.

How this works
The height available for cartons is the overall height limit minus the pallet's own base height, the deck plus stringers or blocks, not the limit applied directly to the carton stack. Layers per pallet is that usable height divided by carton height, rounded down, since a partial layer is not stable and would push the total past the limit. The resulting pallet height is the base height plus the layer count times carton height, and it always stays within the entered limit by construction.
Key terms
- Pallet base height: the empty pallet's own height before any cartons are loaded, deck plus stringers or blocks.
- Overall height limit: the height ceiling measured from the floor, a trailer's clear height, a rack beam, or a dock door.
- Usable stack height: the overall height limit minus the pallet base height, the space actually available for cartons.
- Height limit utilization: the share of the overall height limit the finished pallet actually uses.
Assumptions
- Uniform carton height across every layer
- The height limit is measured from the floor, not from the top of the pallet deck
Limitations
- Does not itself check carton footprint or weight, see Cartons per Pallet Optimizer
- Does not check whether the resulting pallet height clears a specific trailer for double-stacking, see Double Stack Feasibility

Worked example
A pallet with an 8 inch base loads 10 inch tall cartons against a 65 inch overall height limit. Subtracting the base first leaves 57 inches usable, for 5 full layers and a 58 inch total pallet height, inside the limit. A calculation that skips subtracting the base height and divides the full 65 inches by 10 gets 6 layers instead, then adding the 8 inch base back gives a 68 inch total, 3 inches over the same 65 inch limit, a load that would not clear the trailer door or rack beam it was sized against.
Common use cases
- Sizing a pallet's layer count against a trailer's clear height before loading
- Checking a rack beam or dock door clearance before finalizing a stack height
- Feeding a finished pallet height into Double Stack Feasibility to check trailer double-stacking
