Understanding Warehouse Racking Systems
Warehouse racking refers to structured storage systems designed to hold pallets, boxes, or materials. Common racking types include:
- Selective Pallet Racking – Most common, easy access to each pallet.
- Drive-In Racking – Maximizes storage density, reducing aisles.
- Cantilever Racking – Ideal for long items like pipes and lumber.
- Mezzanine Racking – Uses vertical space for additional storage.
Choosing the right racking system depends on space availability, product weight, and warehouse operations.
Key Factors in Warehouse Racking Calculation
Before calculating warehouse racking, consider the following factors:
1. Warehouse Space Dimensions
- Measure the total warehouse area (length, width, and height).
- Consider obstructions like pillars, vents, or fire exits.
2. Aisle Width
- Aisle width depends on forklift type:
- Standard forklifts need 3.5 to 4 meters.
- Narrow aisle forklifts need 1.5 to 2 meters.
3. Racking Unit Size
- Standard rack sizes vary but typically range from:
- Height: 2.5m – 12m
- Depth: 900mm – 1.5m
- Width: 2.5m – 3.6m per section
4. Load Capacity Per Level
- Calculate total weight each shelf must support.
- Overloading racks can lead to collapse and safety hazards.
5. Vertical Space Utilization
- Optimize vertical space while ensuring safety and forklift accessibility.
Step-by-Step Guide to Calculate Warehouse Racking
1. Determine Available Warehouse Space
Measure the total warehouse area:
Formula:
For example, if your warehouse is 50m long and 30m wide, the total available space is:
2. Calculate Aisle Space
Aisle space ensures proper forklift movement and worker safety.
Formula:
For five aisles, each 3.5m wide:
Total available storage space:
3. Determine Racking Dimensions
The number of racks depends on available space and rack dimensions.
If each rack is 3m wide, the number of racks per row:
If 5 rows fit in the warehouse:
4. Calculate Weight Capacity
Ensure racks support maximum pallet load.
If each shelf holds 500kg per pallet and there are 4 shelves per rack:
For 20 racks:
5. Optimize Storage Efficiency
Maximize vertical space by ensuring racks do not exceed safe stacking height.
- Consider pallet overhang to prevent tipping.
- Use labels and aisle markings to enhance efficiency.
- Invest in adjustable racking systems for flexibility.
Common Warehouse Racking Mistakes to Avoid
- Ignoring weight limits, leading to structural damage.
- Poor aisle planning, restricting forklift movement.
- Not using vertical space effectively, wasting storage potential.
- Skipping safety inspections, increasing the risk of accidents.

Warehouse Racking Calculation Summary Table
| Factor | Formula / Consideration | Example Calculation |
|---|---|---|
| Warehouse Area | Length × Width | 50m × 30m = 1,500m² |
| Aisle Space | Aisle Width × No. of Aisles | 3.5m × 5 = 17.5m |
| Storage Width | Warehouse Width - Aisle Space | 30m - 17.5m = 12.5m |
| Number of Racks | Storage Width ÷ Rack Width | 12.5m ÷ 3m = 4 racks per row |
| Total Racks | Racks per Row × Rows | 4 × 5 = 20 racks |
| Weight per Rack | Load per Shelf × Shelves per Rack | 500kg × 4 = 2,000kg |
| Total Weight Capacity | Total Racks × Weight per Rack | 20 × 2,000kg = 40,000kg |
