Aisle width should be based on the handling equipment and load, with added allowance for operating conditions and risk.
Aisle width should be based on the handling equipment and load, with added allowance for operating conditions and risk.
Start with equipment data
Use the equipment manufacturer’s right-angle stacking or minimum aisle specification for the actual truck and load. Nominal truck width alone is not enough.
Add real-world allowances
Pallet overhang, imperfect placement, rack protection, pedestrian separation, floor conditions, visibility, and driver skill can require additional room.
Separate aisle purposes
Storage aisles, main travel aisles, staging lanes, pedestrian paths, and emergency access serve different functions. Do not apply one width to every area.
Questions answered
Frequently asked questions
Can I measure aisle width from rack face to rack face?
Use the dimension method required for the equipment and design, accounting for loads and obstructions.
Are narrower aisles always more efficient?
No. Density gains can be offset by specialized equipment, slower travel, congestion, and reduced flexibility.
