Warehouse Layout Design Best Practices to Reduce Picking Time

Picking accounts for as much as 55% of total warehouse operating costs, making it one of the most critical processes to optimize. Slow or inefficient picking can drain labor budgets, reduce throughput, and frustrate customers with late or inaccurate orders.

At Southwest Warehouse Solutions, we’ve helped countless facilities improve their warehouse layout design to shorten picking time, boost ROI, and maximize every square foot.

Layout Principles That Impact Order Picking Efficiency

An efficient warehouse layout design starts with core principles that ensure both workers and materials move fluidly throughout the facility. By structuring your storage areas and pathways with these fundamentals in mind, you can significantly reduce wasted steps and improve fulfillment speed.

Clear Flow of Movement

A well-designed warehouse layout ensures products move seamlessly from receiving to storage, then to picking and shipping, without unnecessary detours. Minimizing backtracking reduces congestion in busy areas and keeps operations running smoothly. This streamlined flow helps improve picking speed while reducing worker fatigue and equipment traffic jams.

Strategic Storage Placement

High-demand SKUs should be stored in locations that are quick and easy to access, ideally near packing and shipping areas. This strategic positioning minimizes pickers’ travel time, allowing them to process more orders in less time. SWWS often recommends reorganizing storage to prioritize accessibility for top-moving products.

Optimized Aisle Widths

Balancing narrow aisles for maximum storage capacity with wide enough aisles for safe and efficient forklift operation is key. Too narrow, and movement slows due to congestion; too wide, and valuable storage space is wasted. Proper aisle width design improves both productivity and safety, supporting a smoother warehouse workflow.

Logical Segmentation

Dividing the warehouse into clearly defined zones based on product type, order volume, or picking method improves organization and reduces confusion. This segmentation prevents worker overlap, minimizes cross-traffic, and allows for more focused picking routes. The result is a more efficient operation with fewer errors and faster fulfillment times.

When these foundational principles are implemented, the warehouse becomes easier to navigate, and your picking team can work faster with fewer errors. SWWS specializes in designing layouts that incorporate these best practices without requiring an expansion.

Data-Backed Design Strategies: Zoning, Slotting, and Flow Paths

Data is one of the most valuable tools for designing an effective warehouse layout. By tracking SKU movement, order trends, and worker travel paths, you can reconfigure your facility to save measurable time.

Zoning

Zoning is the process of grouping similar products together or creating dedicated areas for high-priority SKUs to streamline picking. For instance, placing fast-moving products near packing stations can significantly cut travel time and increase throughput.

Slotting

Slotting strategically assigns product locations based on how often they’re accessed and their size, shape, or weight. Heavy or bulky items are best kept at ground level for safety, while smaller, high-volume SKUs can be placed in easily accessible bins. When designed properly, slotting reduces picker strain, minimizes handling errors, and accelerates fulfillment speed.

Flow Paths

Flow paths are the designated routes pickers take to move through the warehouse, and optimizing them eliminates wasted steps. Poorly designed paths can cause congestion, backtracking, and delays.

Best Practices for Reducing Travel Time and Increasing Throughput

Reducing travel time is one of the fastest ways to cut picking costs. With the right strategies, you can refine your warehouse layout design and significantly increase throughput without additional labor.

Use a Golden Zone

The golden zone is the most ergonomically efficient picking area, typically between a worker’s knees and shoulders. Placing your highest-demand SKUs here minimizes bending, reaching, and lifting strain, which saves valuable seconds per pick but and reduces the risk of workplace injuries. Emphasizing golden zone storage in warehouse layout design helps maximize comfort, efficiency, and picking accuracy without sacrificing overall storage capacity.

Implement Cross-Aisle Shortcuts

If workers must walk the full length of an aisle to retrieve a single item, picking time skyrockets. Cross-aisle shortcuts allow pickers to cut across mid-aisle, dramatically reducing walking distances and congestion. Incorporating strategic cross-aisle breaks into warehouse layout design to balance storage density with optimal movement flow, boosting both throughput and worker efficiency.

Leverage Batch or Zone Picking

Batch picking combines multiple orders in a single trip, while zone picking assigns workers to specific warehouse sections. Both methods significantly cut travel time and reduce traffic in busy aisles. SWWS designs warehouse layouts that support these systems, ensuring that pick paths, slotting, and storage zones align with your fulfillment strategy for maximum efficiency.

Utilize Dynamic Slotting Strategies

Dynamic slotting involves periodically reassessing and rearranging SKU locations based on seasonal demand or order trends. This ensures fast-moving products are always positioned for quick access. SWWS helps facilities implement dynamic slotting as part of their warehouse layout design, keeping travel times low year-round and supporting fluctuating inventory demands without costly reconfiguration.

Incorporate Pick-to-Light or Voice-Directed Systems

Technology-driven picking aids like pick-to-light or voice-directed systems streamline order fulfillment by guiding workers directly to the correct pick location. These systems reduce searching and decision-making time, improving accuracy and speed. Integrating these technologies into your warehouse layout design can complement optimized pick paths and enhance your facility’s overall operational throughput.

How Warehouse Design Impacts Labor and Fulfillment Speed

Your warehouse layout design affects travel time and has a direct influence on labor productivity, error rates, and customer satisfaction. An inefficient layout increases the number of steps per order, strains your workforce, and slows down fulfillment during peak demand.

For example, poor slotting might cause workers to visit the same aisle multiple times in one shift, while congestion in high-traffic zones can lead to bottlenecks and delayed shipments. By partnering with SWWS to redesign your space, you can reduce wasted motion, improve order accuracy, and fulfill more orders per hour without hiring additional staff.
