Pallet Calculator
Compare both carton orientations, see footprint utilization, and apply height and load-weight limits before building a pallet.

What this pallet calculator checks
Enter carton, pallet, height, overhang, and weight values. The result compares two uniform layer orientations and reports whether stack geometry or the entered maximum load controls the final box count.
Plan boxes per pallet
Enter measured limits
Use the same units for every dimension. Enter zero overhang unless current packaging and carrier rules permit it.
Your inputs
Default worked example. Edit the inputs to calculate your scenario.
Default worked example
The length × width grid fits 16 boxes per layer. 7 whole layers fit by height, and the final count is 110 after the entered 2,200 lb load limit.
Uniform layer orientation comparison
| Orientation | Grid | Boxes per layer | Footprint use |
|---|---|---|---|
| Length × width | 4 × 4 | 16 | 100% |
| Width × length | 4 × 3 | 12 | 75% |

Pallet Calculator FAQs
Does the pallet calculator rotate boxes?
Yes. It compares uniform length-by-width and width-by-length orientations and selects the one with more whole cartons per layer.
Does the result include a pallet weight limit?
Yes. The final carton count is the lower of the geometric stack count and the entered maximum load divided by carton weight.
Can mixed carton patterns fit more boxes?
Sometimes. This calculator compares two uniform grids; mixed rows, pinwheel patterns, compression, and stability require a detailed palletization plan.
Is overhang always allowed?
No. Enter zero unless the pallet, packaging, warehouse, and carrier rules explicitly permit overhang.
How to use the calculator
Estimate a uniform box grid on a pallet using inches for dimensions and pounds for weights. Enter available CARGO height above the pallet base and available CARGO load weight after accounting for tare. Overhang is added to each side of the footprint only; follow the actual permitted policy.
What the result means
The maximum layers by height and full-layer footprint-use cards describe geometric capacity. The final box count and loaded height also reflect weight limits. A partly filled top layer is possible. The two-row table compares uniform orientations rather than a mixed-row packing optimization.
Formula and units
Usable length/width = pallet length/width + 2 × allowed overhang. Compare floor(length/box length) × floor(width/box width) with the rotated grid. Equal capacities keep the length-by-width orientation. Height-limit layers = floor(cargo height/box height). Final boxes = minimum(full-grid boxes × height-limit layers, floor(cargo weight limit/box weight)). Loaded height uses only the layers needed by that final count.
Worked examples
12 × 10 × 8 in boxes: Box length: 12 in; Box width: 10 in; Box height: 8 in; Box weight (lb): 20 lb; Pallet length: 48 in; Pallet width: 40 in; Max stack height: 60 in; Allowed overhang per side (in): 0 in; Maximum carton load (lb): 2200 lb.
Example result: Boxes per layer: 16; Selected orientation: Length × width; Maximum layers by height: 7; Total boxes: 110; Full-layer footprint use: 100%; Loaded height: 56 in; Load weight: 2,200 lb; Limiting factor: Maximum load weight.
Box length: 18 in; Box width: 15 in: Box length: 18 in; Box width: 15 in; Box height: 12 in; Box weight (lb): 20 lb; Pallet length: 48 in; Pallet width: 40 in; Max stack height: 60 in; Allowed overhang per side (in): 0 in; Maximum carton load (lb): 2200 lb.
Example result: Boxes per layer: 6; Selected orientation: Width × length (rotated); Maximum layers by height: 5; Total boxes: 30; Full-layer footprint use: 84.4%; Loaded height: 60 in; Load weight: 600 lb; Limiting factor: Stack geometry.
Limitations and common mistakes
This is a uniform-grid estimate, not a loading approval. It does not determine compression strength, stability, center of gravity, pallet rating, wrapping, trailer clearance or safe overhang. Whole layout counts must remain within the supported safe integer range. Inputs retain at most 64 decimal characters and exponents from -308 to 308.
Use cargo height and cargo weight capacity, excluding the pallet base and tare. Do not interpret full-layer footprint use as the actual coverage of a partial layer. Decimal floors and layer counts use unrounded inputs, so a visually rounded dimension can sit just above or below a count boundary.
Sources and assumptions
The grid, utilization, height, and weight arithmetic are mathematical; mixed patterns, compression, stability, overhang policy, and carrier rules remain outside the model.
