About this calculator
Compare clear equipment dimensions and available payload for identical loaded pallets. Use measured loading clearance and approved stacking levels, rather than relying on a vehicle size label.
Inputs
How to use this calculator
Equipment scenario
- Usable equipment length (in)Net floor length; account for doors and clearance first.
- Usable equipment width (in)Enter measured net width, not an unverified equipment label.
- Usable equipment height (in)This must also account for the loading path and door clearance.
- Available cargo payload (lb)Remaining payload for these full pallets, not the vehicle gross weight rating.
Shared inputs
- Loaded pallet length (in)Include overhang.
- Loaded pallet width (in)Include overhang.
- Loaded pallet height (in)Include the pallet deck.
- Gross weight per loaded pallet (lb)Include packaging and pallet tare.
- Approved maximum pallet levelsKeep 1 unless stacking is separately approved for the product, pallet, handling and transport conditions.
- Grid orientationCompare two uniform grid orientations; this is not mixed-direction optimization.
Enter the shipment or scenario values, then select Calculate result.
Method
Formula and variables
Floor positions = max of the allowed uniform grids. Levels = min(floor(clear height ÷ loaded height), approved levels). Geometric capacity = positions × levels. Final capacity = min(geometric capacity, floor(available payload ÷ gross pallet weight)). Scenarios are alternatives, never added.

Interpret the result
Geometric capacity and weight capacity are separate limits. The usable result is the smaller count for each alternative equipment scenario, and alternative capacities are not added.
Outputs: Geometric and payload-limited pallet capacity by equipment
Geometric estimate for identical full pallets only. No mixed rows, wheel wells, axle loads, road limits, stability, rack strength or handling acceptance is certified. Dimensions, payload and approved levels are user inputs; the example is not a standard truck/container specification.
Worked example
Check the arithmetic
This example uses the starting values shown above. The arithmetic below is calculated independently of the interactive result.
Work through the calculation
- Original floor grid: floor(240 ÷ 48) × floor(96 ÷ 40) = 5 × 2 = 10 positions; rotated grid = floor(240 ÷ 40) × floor(96 ÷ 48) = 6 × 2 = 12.
- Approved levels = 1, so geometric capacity = 12 × 1 = 12 pallets.
- Payload allows floor(12,000 ÷ 1,200) = 10 pallets. Usable capacity = min(12, 10) = 10.
Compare the displayed result
Expected displayed result: 10 pallets
FAQs
Does a geometric second level mean stacking is approved?
No. The approved maximum levels input independently caps the height-based count. Keep it at one unless the load and operating conditions have separate approval.
Example inputs and options
