How to use Pallet Calculator
- Use verified deck dimensions and usable carton-stack height above the pallet rather than mixing total unit-load height with carton height allowance.
- Enter the carton's stable footprint, gross weight, pallet base height, and usable payload limit for the operation.
- Use the lower geometry/weight count, then check pallet tare, compression, containment, overhang, center of gravity, rack, forklift, and vehicle limits.
Calculator guide
Understanding Pallet Calculator
Pallet capacity depends on deck footprint, usable stack height, and payload weight. This screening model compares two uniform carton orientations, calculates complete layers, and then uses the lower of geometry capacity and payload capacity.
Calculation method
How the calculation works
Compare both uniform orthogonal footprint orientations, calculate full layers within the usable stack-height envelope, and use the lower of geometry capacity and payload-weight capacity. For each orientation, floor-divide usable deck dimensions by carton footprint dimensions. Multiply the better layer count by complete height layers, floor-divide usable payload by gross carton weight, and take the lower count.
Detailed calculation process
Apply deck, height, and payload limits in sequence
A high footprint count is useful only when complete layers fit the height envelope and the resulting mass stays within payload.
General formula: Geometry count = best cartons per layer × full layers; Loadable cartons = min(geometry count, floor(payload ÷ carton weight)) Both footprint orientations use floor division, and only complete layers are included. Payload is checked independently.
What each symbol means
Worked substitution with the default inputs
Deduct pallet tare when appropriate and complete stability, compression, containment, rack, forklift, door, and vehicle checks before approving the unit load.
Load engineering
Check the constraints that can override the geometric maximum
Cube utilization is useful only when the unit load can be handled safely.
Worked situations
Practical examples
- A 120 cm by 100 cm deck fits 3 by 3 cartons when a 40 cm by 30 cm footprint is used, producing 9 cartons per layer.
- A 150 cm usable stack allowance with 25 cm cartons permits 6 full layers and 54 cartons geometrically.
- At 12 kg per carton and a 1,000 kg usable payload limit, weight allows 83 cartons, so geometry remains binding in the default case.
Better inputs
Useful tips
- Reserve clearance for corner boards, slip sheets, stretch wrap, and rack tolerances.
- Check gross pallet weight after calculating cube utilization.
- Test interlocked patterns separately because a simple full-grid model cannot represent them.
Before relying on the result
Limitations and common mistakes
- The model allows one carton size and one uniform orientation per layer; mixed and interlocked patterns are excluded.
- Pallet tare is not deducted automatically from payload, and load stability, compression strength, edge overhang, mixed SKUs, and vehicle cube remain outside the calculation.
- The displayed height is the pallet base plus the configured full geometry layers; a weight-limited partial load may use fewer layers.

Calculated from the entered shipment values and stated rate rules. Carrier tariffs, quotes, service rules, customs treatment, and claims terms control actual charges.
Frequently asked questions
Does the calculator mix carton orientations in one layer?
No. It compares two uniform orthogonal grids; a mixed or pinwheel pattern needs a dedicated packing layout.
Is pallet height included in the usable stack-height input?
No. Enter carton-stack height above the pallet separately; the calculator adds the pallet base height for the displayed unit-load envelope.
Does payload include pallet tare?
The model limits carton weight only. Reduce the entered usable payload first when pallet tare must be included in the equipment or transport limit.
Does the highest carton count guarantee the best load?
No. Stability, compression, weight distribution, labels, airflow, containment, and unloading sequence may favor a lower count.
