Understanding Space Efficiency
How Aisle Width & Building Height Impact Storage
The key to maximizing warehouse storage is understanding the relationship between forklift type, aisle width, and building clear height. Narrower aisles and taller buildings dramatically increase pallet positions.

Why Aisle Width Matters
In a typical warehouse, aisles consume 50-60% of floor space with counterbalanced forklifts. By switching to VNA equipment with 5.5ft aisles, you can add up to 50% more rack positions in the same building footprint. This is often more cost-effective than expanding or relocating to a larger facility.
