Inputs
Enter dimensions, optional deductions, mezzanine, and storage assumptions.
Example Data Table
Sample inputs and typical outputs for a medium warehouse.
| Scenario | Zones (L×W) | Deductions | Office / Dock / Utility | Mezzanine | Net Storage (approx.) |
|---|---|---|---|---|---|
| Metric example | Main: 60×40 m Wing: 20×15 m |
Core: 6×6 m Pit: 4×3 m |
Office: 250 m² Dock: 300 m² Utility: 120 m² |
40% of ground | ~ 2,818 m² |
| Imperial example | Main: 200×130 ft Annex: 80×50 ft |
Core: 20×20 ft | Office: 2,800 ft² Dock: 3,200 ft² Utility: 1,100 ft² |
Direct: 6,000 ft² | ~ 24,100 ft² |
Note: Example outputs are rounded and depend on your exact entries.
Formula Used
- Zone area = Length × Width (for each rectangle).
- Gross floor area (ground) = Σ(Zone areas).
- Deductions = Σ(Void areas), where Void area = Length × Width.
- Mezzanine area:
- Percent mode: Mezzanine = Gross × (Mezzanine% / 100)
- Direct mode: Mezzanine = Entered mezzanine area
- Total built-up area = Gross + Mezzanine.
- Net storage area = Gross − Office − Dock/Staging − Utility/Support − Deductions.
- Effective storage area = Net storage × (Utilization% / 100).
- Pallet positions ≈ floor( Effective storage ÷ (Pallet area × Aisle factor) ).
- Net storage volume = Net storage area × Clear height (optional).
Tip: Use multiple zones to model L-shapes, corridors, or step-backs.
How to Use This Calculator
- Select Metric or Imperial units at the top.
- Enter the warehouse footprint using one or more zones (rectangles).
- Add deductions for pits, lift cores, shafts, or non-usable areas.
- Optionally enter office, dock, and utility allocations.
- If applicable, include a mezzanine as a percent or direct area.
- For a quick capacity check, set utilization, pallet size, and aisle factor.
