Very Narrow Aisle vs. Standard Racking: Which Maximizes Your Warehouse Space?

July 07, 2026

If your warehouse is running out of space, Very Narrow Aisle (VNA) racking can significantly increase storage capacity without expanding your facility.

However, the right choice depends on your inventory volume, throughput requirements and equipment investment. MHS Lift helps businesses evaluate both options and design the most efficient warehouse layout.

Which Racking System Stores More Inventory?

Standard pallet racking typically requires aisle widths of 10-12 feet to allow forklifts to operate safely. VNA systems reduce aisle widths to as little as 5-7 feet, creating more room for additional rack positions.

The result? Many warehouses can increase storage capacity by 30% to 50% within the same building footprint by transitioning to a VNA layout.

What Are the Trade-Offs?

While VNA systems maximize storage density, they require specialized equipment such as turret trucks or VNA forklifts designed to operate in tighter spaces. Standard racking offers greater flexibility and lower upfront equipment costs, making it a practical choice for operations with lower storage demands.

VNA Advantages:

  • Higher storage capacity
  • Better use of existing square footage
  • Reduced need for facility expansion

Standard Racking Advantages:

  • Lower equipment investment
  • Greater operational flexibility
  • Simpler implementation

Which Option Is Right for Your Warehouse?

The answer depends on your inventory profile, throughput goals and growth plans. A warehouse running out of storage space may benefit significantly from VNA design, while a facility focused on flexibility may be better served by traditional racking.
