What is warehouse capacity?
How do we determine warehouse capacity?
Total warehouse area (A) – expressed in square meters (m²).
Non-storage area (B) – including offices, technical zones, and transport routes.
Maximum storage height (C) – including racking systems and the space required for lighting and installations (e.g., fire protection systems). In other words, this is the maximum height that warehouse racks can reach, regardless of their type: pallet racking, mobile racking, cantilever racking, etc.
Warehouse capacity formula:
Example of converting total facility space into storage capacity
et’s assume:
– A: Warehouse area = 80,000 m²
– B: Non-storage areas = 15,000 m²
– C: Maximum storage height = 12 m
Applying the formula: (80,000 – 15,000) × 12 = 780,000 m³
This means the warehouse has 780,000 cubic meters of storage space. This space must be equipped with appropriate racking systems to enable logistics operations. The most common solution is pallet racking.
Types of warehouses and their equipment
Efficient warehouse management is crucial for both manufacturing and logistics operations. Proper building adaptation and the right choice of equipment (including racking systems) ensure optimal storage.
There are different types of warehouses, varying in load capacity, purpose (e.g., cold storage), and configuration options (e.g., installation of picking shelves). Pallet racking systems offer the widest range of configurations and accessories.
Warehouse equipment
Defining the warehouse purpose before purchasing equipment is essential. Choosing the right racking system is key to achieving optimal storage and management performance.
The market offers many solutions: pallet racks, cantilever racks, mobile racks, mezzanines, and warehouse management systems (WMS). The choice of racking also determines the type of forklifts required.
Pallet or cantilever racking? Which system to choose?
How can an investor decide which system is best? If unsure, it is best to consult warehouse system specialists. Gather all investment data, invite experts for a site visit, and discuss operational needs.
For high-bay warehouses, pallet or dynamic racking systems are recommended. In facilities with limited space, mobile or drive-in systems save space at the cost of accessibility. For small-item operations, shelving systems or automated storage solutions work best.
Key performance indicators
In addition to layout, efficiency indicators are crucial:
- Space utilization ratio (storage area vs. total area)
- Storage density (number of pallets or units per square meter)
Optimizing these increases capacity and improves operational efficiency while reducing time and costs.
How to increase warehouse space utilization?
Warehouse racking design
Well-designed racking systems can increase pallet storage capacity by several dozen percent.
By selecting the right systems—such as pallet, flow, or high-bay racking—you can maximize both horizontal and vertical space. Modern solutions like mobile or automated systems reduce unused space and improve access.
Efficient space management
Properly designed racking layouts improve safety, ergonomics, and reduce operational costs. Companies can increase capacity without expanding the facility, gaining a competitive advantage.
What to consider when analyzing a racking design?
Aisle width vs. forklift dimensions
Ensure aisles match forklift requirements.
Beam height vs. pallet size
Proper beam placement allows more storage levels.
Rack height vs. building height
Account for installations like fire protection systems.
Storage method
Changing how goods are stored (e.g., loose vs. palletized tires) can increase capacity.
Warehouse zoning
Well-planned zones improve efficiency and reduce operation time.
Warehouse safety
All racking systems must meet strict safety standards to protect employees and goods.
Proper layout, clear transport paths, safety barriers, and anti-slip surfaces (especially in cold storage) reduce accident risk. Regular safety training and PPE (helmets, gloves) are essential.
Monitoring systems and motion sensors enable quick response to threats and minimize losses.
Ergonomics in the warehouse
Ergonomics is crucial for employee health and comfort. Proper workstation design, correct rack height, and equipment like forklifts and lifts reduce physical strain.
Reducing manual handling prevents injuries and increases efficiency. Good lighting and ventilation also improve performance and reduce errors.
Picking shelves for better ergonomics
Most warehouses include picking zones—often created by adding shelves to lower levels of pallet racks. These allow workers to access frequently ordered items without forklifts.
Performance and safety in the workplace
Combining efficiency, safety, and ergonomics creates a productive and secure work environment. Investing in these areas improves operations and team morale.
Operational efficiency in the warehouse
Warehouse efficiency directly impacts the entire supply chain. Optimal rack layout, modern storage systems, and automation speed up loading and unloading processes.
Proper planning reduces order picking time, increases throughput, and lowers operational costs.
Modern technologies like WMS (Warehouse Management Systems) enable real-time inventory tracking and product movement monitoring, reducing errors and improving workflow.
