Warehouse Space Calculator
A warehouse space calculation from pallet count to floor area — square footage and m², plus the storage capacity that area gives you — using the same aisle and rack math as our floor planner. Your inputs stay in the URL — bookmark the result.
Estimated total footprint
588 m²≈ 6,334 sq ft
Numbers are the start. The layout is where it goes wrong.
Draw this warehouse in 3D — the planner checks forklift reachability, 90° turn clearance, slab loading and zone rules while you drag.

The number people get wrong is not the pallet size — it is everything around the pallet. Work in four steps, and always start from pallets stored, not products.
1. Ground positions = pallets ÷ levels high
Racking stores pallets vertically. 500 pallets 4 levels high = 125 ground positions. This is the single biggest lever — one extra rack level cuts your ground footprint by a quarter.
2. Footprint per position + a share of the aisle
Plan ~1.2 × 1.1 m per pallet position including the rack steel. Then add half an aisle per rack row, because two rows share one aisle. Aisle width is set by the forklift: reach truck ~2.9 m, counterbalance ~3.7 m, VNA ~1.8 m.
3. Storage area = positions × (footprint + aisle share)
This is the racked-and-aisled floor — the part that actually holds inventory.
4. Add support space (÷ by 1 − 0.35)
Receiving, shipping, staging, battery charging and offices are typically 30–40% of the building. Divide storage area by 0.65 to gross up to the total. Skip this and you undercount by roughly a third.
// Worked example — 500 pallets, 4 levels, reach trucks
Ground positions = 500 ÷ 4 = 125
Per position = (1.2 × 1.1) + (2.9 × 1.2 ÷ 2) = 1.32 + 1.74 = 3.06 m²
Storage area = 125 × 3.06 = 383 m²
Total = 383 ÷ 0.65 ≈ 590 m² (~6,350 sq ft)
The formula gives you a number. Whether that space actually works depends on the layout — can every forklift reach every pallet, turn into every bay, and does the slab carry the load?
