As warehouse space becomes more valuable, businesses are increasingly turning to high-density storage systems to maximize efficiency. Double deep pallet racking is one such system that balances storage capacity with accessibility. To fully leverage its benefits, understanding the correct dimensions in inches is essential. This article walks you through the key sizing considerations, standard measurements, and tips to select the optimal configuration for your warehouse.
What Is Double Deep Pallet Racking?
Double deep racking is a storage system that arranges two rows of pallets deep, one behind the other. Unlike selective pallet racks that allow access to each pallet individually, double deep racks require a deep reach forklift to access the rear pallet. This configuration increases storage density by up to 30%, making it ideal for warehouses with high volumes of the same SKU.
This system is commonly used in industries like food and beverage, manufacturing, and retail distribution where product rotation is moderate and space optimization is a priority.
Standard Double Deep Pallet Racking Dimensions (in Inches)
While dimensions can vary based on pallet sizes and custom warehouse designs, the following are typical U.S. standards for double deep pallet rack measurements:
Standard Pallet Size: 48” deep x 40” wide
Rack Depth: 96” (to accommodate two 48” pallets back-to-back)
Beam Lengths: Common options include 96”, 108”, 120”, and 144”
Frame Heights: Typically 96”, 144”, 192”, or higher depending on ceiling clearance
Aisle Width: Minimum of 108″–132″ required for deep reach truck maneuvering
Each bay usually stores four pallets—two per position, stacked two deep—significantly improving cube utilization compared to traditional selective racking.
Customization and Configurable Options
Double deep pallet racking can be tailored to suit your exact storage needs. Key customization options include:
Adjustable Beam Levels: Adapt shelf height for varying pallet heights
Load Capacities: Racks can be designed to handle heavy-duty pallets with weight ratings from 2,000 to 5,000+ lbs per level
Custom Depths and Widths: Non-standard pallets may require 42”, 48”, or even 60” depth configurations
Accessories: Add wire decking, pallet backstops, row spacers, or rack guards for added safety and functionality
Custom sizing ensures compatibility with your equipment, workflow, and inventory types.
How to Choose the Right Dimensions for Your Double Deep Pallet Racking
Selecting the correct dimensions for your double deep pallet racking starts with a clear understanding of your operational needs. Here are the key factors to consider:
Pallet Size & Weight: Know your standard load dimensions and weight per pallet to determine rack depth, beam spacing, and capacity requirements
Forklift Type: Ensure your deep reach truck has the right mast height and reach depth to access rear pallets safely
Available Space: Measure your ceiling height, floor space, and column placements to design an optimal layout
Aisle Planning: Leave sufficient aisle width for safe navigation and turning radius of reach trucks
Fire Code Compliance: Ensure enough vertical clearance for sprinkler systems and ventilation
Product Flow: Use FIFO/LIFO strategies to determine if double deep racking supports your fulfillment model
Taking a systematic approach reduces errors and helps you avoid costly redesigns down the line.
Common Mistakes to Avoid
Even seasoned warehouse managers sometimes overlook key aspects when implementing double deep racks. Common errors include:
Misjudging Aisle Width: Not accounting for the extra reach space needed for deep access forklifts
Improper Beam Length: Selecting beams too short or long for your pallet width, leading to poor fit or overhang
Overloading Racks: Exceeding the weight limit of beams or frames can compromise safety
Ignoring Vertical Clearance: Not leaving enough space between pallets and ceilings or sprinklers
Lack of Future Planning: Failing to anticipate inventory growth or SKU changes
Proper planning and professional consultation can help avoid these issues.
Conclusion
Understanding the dimensions of double deep pallet racking in inches is critical to maximizing warehouse efficiency, safety, and capacity. From standard pallet sizes to custom configurations, every detail plays a role in the overall performance of your storage system. Whether you’re upgrading your current racking or planning a new facility, investing time in proper dimension planning will pay long-term dividends.
