Pallet Space Calculator

Turn dimensions into reliable pallet capacity numbers fast. Add gaps, aisles, and stacking rules easily. Export results for teams, quotes, and execution everywhere now.

Inputs
Enter your space and pallet/unit-load details. Then calculate capacity.
Shipping & Logistics
Space
If you enable stacking, height becomes important.
Pallet / unit load
All length inputs use the same unit.
Constraints
Stacking
Max layers lets you enforce crush limits or SOP rules.
Weight limits (optional)
If both are set, capacity is capped by payload.
Quick actions
Tip
Use utilization for pillars, damage zones, and irregular edges.
Example data table
Sample scenarios for a trailer bay or a marked warehouse zone.
Scenario Space (L×W×H) Pallet (L×W×Load H) Gaps / Clearances Util / Aisle Result (approx.)
Dry van plan 12.0×2.35×2.70 m 1.20×1.00×1.50 m 0.02 m gap, 0.05 m edge, 0.10 m top 92% / 10% ~16 pallets (single layer), 1–2 layers by rules
Warehouse zone 20.0×10.0×6.00 m 1.20×1.00×1.60 m 0.03 m gap, 0.10 m edge, 0.20 m top 90% / 15% ~90–120 pallets, depending on stacking
High clearance rack aisle 30.0×4.0×8.00 m 1.20×0.80×1.40 m 0.02 m gap, 0.05 m edge, 0.20 m top 95% / 25% ~60–80 pallets, with access allowance applied
Examples are illustrative. Always validate against facility SOP and equipment clearances.
Formula used
  • Pallet footprint area: Ap = Lp × Wp
  • Usable dimensions: Lu = L − 2E, Wu = W − 2E, Hu = H − T
  • Count along a direction (with gap g): n = ⌊(S + g) / (P + g)⌋
  • Pallets per layer: Nlayer = nL × nW (checked for both orientations)
  • Operational adjustment: Noper = ⌊Nlayer × U × (1 − A)⌋, where U is utilization ratio and A is aisle ratio
  • Layers (stacking): Nlayers = ⌊(Hu + gz) / (Hload + gz)⌋, limited by max layers
  • Total pallets: Ntotal = Noper × Nlayers, capped by payload if provided
Practical note: Utilization and aisle allowance approximate non-rectangular losses. For racking, use verified slot counts from your layout drawings.
How to use this calculator
  1. Pick one unit, then enter the space length and width.
  2. Enter pallet length, width, and unit load height.
  3. Set gaps and edge clearances to match handling equipment.
  4. Add utilization and aisle allowance for access and obstacles.
  5. Enable stacking if allowed, then set max layers if needed.
  6. Press calculate to see totals above the form.
  7. Export the summary as CSV or PDF for sharing.
