Optimising your warehouse can be simpler than expected with the right storage solutions. We have been asked multiple times about the distinction between Narrow Aisle Racking (NAR) and Very Narrow Aisle (VNA) Racking. This is understandable because of the slight similarity in their names. We want to clarify that both options are used to boost storage capacity by narrowing aisle widths (as suggested in the phrase “narrow”), but they are two different solutions for different environments. Our guide will outline both racking applications, but by the end, you’ll better understand VNA racking systems as one of our most effective racking solutions.
Narrow Aisle Racking Vs. VNA Racking
NAR is intended for companies seeking to boost storage space without making major changes to loading equipment. NAR systems enable the utilisation of additional rows of racks within a designated floor area due to aisle widths varying from 2.5 to 3 metres. This can greatly boost storage compared to wide aisle systems while accommodating standard forklifts. Nevertheless, the requirement for precise navigating in the aisles leads to reduced speed of operations and slight decrease the efficiency of pallet retrieval. One of the narrow aisle racking advantages is that it can boost storage capacity without the need for specialised equipment. For a more in-depth comparison, check out our guide on VNA Racking vs. Drive-In Racking.
VNA Racking is designed to optimise pallet storage space while ensuring convenient access to each pallet. Ideal for companies seeking to maximise warehouse space, this system offers aisle widths varying from 1.7 to 2.2 metres. The phrase “very narrow aisle” emphasises the main benefit of this system, which is its capability to greatly decrease the space between racks, resulting in a higher storage capacity. Companies can boost their storage capacity by up to 40% by narrowing aisle width and raising rack height, as opposed to conventional racking systems.

Additional Information On VNA Racking
- Besides the increased capacity, VNA racking comes with a lot of other advantages. A significant aspect is the utilisation of specialised material handling equipment equipped with radio frequency controls, enabling operators to effectively oversee pallet movements. This technology enables maximum pallet cycles per hour, a handy benefit for high-demand warehouses.
- However, operating in such narrow aisles requires specially designed equipment like combination order pickers, turret trucks, or VNA trucks. These machines are guided along the aisles by wireless control systems, and their masts or forks can rotate to retrieve and deposit pallets as needed. This setup optimises the use of space, but it also requires a perfectly level floor to maintain the stability of the tall racks, which can reach up to 17 metres in height.
- VNA racking is an excellent choice for businesses that need to store a large volume of stock in limited floor space, offering significant advantages in storage capacity and operational efficiency. By investing in this system, companies can dramatically enhance their warehouse’s performance, making it a powerful solution for those prioritising both space and speed.
Key Differences Between Narrow Aisle Racking and VNA Racking
- Aisle width: NAR systems have aisle widths of 2.5 to 3 metres, while VNA racking reduces aisles to 1.7 to 2.2 metres, significantly increasing storage capacity.
- Forklift requirements: NAR systems can be navigated using standard forklifts, though care is needed in narrow spaces. VNA systems require specialised VNA trucks equipped with wire or rail guidance, designed to move within very narrow aisles without turning.
- Storage density: While NAR improves storage density over wide aisle systems, very narrow aisle pallet racking offers the highest density, potentially increasing storage capacity by up to 40%.
- Operational efficiency: NAR systems, though space-efficient, can lead to slower pallet retrieval times due to careful navigation. VNA systems are optimised for speed, using guided trucks to maximise the number of pallet cycles per hour.
- Cost considerations: NAR systems tend to have lower initial costs since they don’t require specialised equipment. However, VNA systems, though more expensive upfront due to the need for specialised trucks and equipment, offer significant long-term savings through enhanced space utilisation and operational efficiency.
Benefits of VNA Racking
The benefits of VNA racking go beyond just storage. By reducing aisle widths and increasing the height of racks, businesses can store more pallets without expanding their warehouse footprint. VNA racking also improves safety, as the use of specialised VNA trucks with radio frequency controls minimises the risk of accidents and maximises operational efficiency. Additionally, VNA systems are ideal for businesses that need to store large volumes of stock but have limited floor space.
For companies looking to achieve greater storage density, very narrow aisle pallet racking is the superior choice. This system is particularly useful in high-demand warehouses where speed and efficiency are critical to daily operations. With the ability to retrieve pallets quickly and safely, VNA racking ensures that businesses can meet their operational targets while optimising warehouse space.
Conclusion
When comparing narrow aisle racking vs. VNA racking, it’s clear that the choice depends on your warehouse’s specific needs. While narrow aisle racking offers a cost-effective solution with standard forklifts, it doesn’t match the storage density and efficiency provided by very narrow aisle pallet racking. For businesses seeking to maximise space and streamline operations, VNA racking is the way forward.
