1. Why Warehouse Design Matters
A well-designed warehouse is not only about shelves and aisles.
It is about flow, safety, visibility, efficiency, accuracy, and the ability to scale with business growth.
Good warehouse design helps you:
- reduce travel time
- improve picking speed
- prevent congestion and accidents
- lower operating costs
- use space effectively
- increase service levels
- support future automation
This guide brings together the most practical and proven best practices used by warehouse managers and
consultants when designing or improving warehouse layouts.
2. Start with the Flow: Make Processes Visible
Warehouse design must follow the natural flow of goods:
Receiving → Put-away → Storage → Picking → Packing → Shipping
Every layout decision should support this sequence.
Why It Matters
A good flow reduces mistakes, congestion, and delays.
What to Do
- keep inbound and outbound flows separate
- avoid crossing paths (forklifts vs pedestrians)
- design clear routes from docks to storage
3. Design Storage Zones with Purpose
Separate the warehouse into logical storage areas:
- fast-moving area (A items)
- medium-moving area (B items)
- slow-moving area (C items)
- oversized area
- hazardous or special goods area
- returned goods zone
Why It Matters
Zone-based storage increases picking speed and reduces congestion.
4. Use Standardized and Clear Location Coding
Location coding is one of the foundations of good warehouse design.
Best Practices
✔ use a simple, readable structure (Row–Bay–Level)
✔ apply large, professional labels
✔ ensure visibility from the aisle
✔ use alphanumeric systems that scale
✔ keep coding consistent across the warehouse
5. Aisle Width and Accessibility
What to Consider
- type of equipment (manual pallet jacks vs reach trucks vs VNA trucks)
- number of pallet movements per hour
- working speed and safety requirements
Why It Matters
Incorrect aisle width is one of the most expensive design mistakes — and one of the hardest to fix later.
6. Slotting and Space Utilization
Slotting means placing products in the best possible location.
Effective Slotting Rules
- fast movers at ergonomic height
- heavy items at lower levels
- seasonal products closer to picking
- bulky items near open areas
- slow movers higher or farther
This significantly improves picking speed.
7. Safety and Ergonomics as Design Elements
Warehouse layout must integrate safety:
✔ pedestrian lanes
✔ forklift routes
✔ fire lanes
✔ emergency exits
✔ anti-slip floor markings
✔ well-lit workstations
Ergonomics reduces operator fatigue and errors.
8. Infrastructure and Equipment Positioning
Key design considerations:
- number and placement of docks
- staging areas
- battery charging stations
- packing tables
- printer and barcode stations
- bin shelving for small parts
- racking alignment and anchoring
Each of these influences daily efficiency.
9. FAQ
Should a small warehouse follow the same design principles as a large one?
Yes — principles are the same, scale is different.
How often should layouts be reviewed?
At least once per year or after major product changes.
Which design mistake is most common?
Aisles that are too narrow or picking areas placed too far from shipping.
Do ABC zones really improve speed?
Yes — dramatically, especially in manual-picking warehouses.
