Warehouse Space Calculator
Aisles and support space take most of it.
Space required
2,500 sq ft
52% used for storage
Only 52% of the floor holds stock. Aisles, receiving, packing and offices take the rest, which is why a quoted requirement based on pallet footprint alone will be short by a factor of two or more.
How the Warehouse Space Calculator works
Only a fraction of a warehouse floor holds stock. Aisles, receiving, packing and offices take the rest, which is why a requirement calculated from pallet footprint alone will be short by a factor of two or more.

Frequently asked questions
How much space do I need?
Racked footprint, divided by one minus the aisle share, divided by one minus the support-space share. Each division compounds, which is why the answer is so much larger than the pallet area.
How much goes to aisles?
Commonly 30% to 40% of the storage area, depending on rack configuration and the equipment used. Narrow-aisle systems reduce it at the cost of specialised trucks.
What counts as support space?
Receiving, dispatch, packing benches, returns processing, offices and welfare. Twenty percent is a reasonable planning figure for a pick-and-pack operation.
Does ceiling height matter?
Enormously — racking upward multiplies capacity without adding footprint. A site with double the clear height can hold nearly double the stock in the same floor area.
