Most warehouse rack layouts fall into a small number of repeatable patterns once you've seen a few. The dimensions change, the SKU profile changes, and the operational tempo changes, but the underlying configurations recur. Below are eight common patterns with diagrams, target position counts, and notes on when to use each.
Each of these can be built in RackCity in 15–30 minutes. If a similar layout would help your project, you can use these as starting points.
Small 3PL Fulfillment
Standard back-to-back layout, 96" beams, 10-ft aisles. Designed for general pallet storage with one dock wall and a small office at front. The most common 3PL starting layout.
Large Distribution Center
Multi-zone DC with dock area, B2B reserve storage, and a smaller selective pick zone. Dead bays accounted for at column lines. Speed bays along the dock wall.
Cold Storage (Double-Deep)
Double-deep configuration to maximize density. Narrow aisles for reach trucks. Common in food cold storage where SKU velocity is moderate and density-per-square-foot is paramount.
E-commerce Fulfillment
Reserve storage in back (B2B), selective single-row pick zone in front, speed bays along the dock wall for staging. Tuned for SKU velocity and pick-line efficiency.
Food Distribution
FIFO-friendly double-deep, vertical orientation perpendicular to the dock wall for fast inbound-to-storage flow. Office at front, dock along full back wall.
Heavy / Wide-Aisle
Wide aisles (12–13 ft) for counterbalance forklifts handling oversize pallets. B2B with column burying in the flue space. Lower density, higher throughput.
Multi-Tenant 3PL
Demising wall separates two tenants. Left side: B2B selective for client A. Right side: double-deep for client B. Per-zone rack configurations are critical for shared facilities.
Retrofit with Column Burying
Existing column grid on 20-ft centers. Racks aligned so columns land in the flue space (buried inside back-to-back pairs) rather than wasting aisle space. Critical for retrofitting existing buildings.
How to pick the right layout for your project
The right layout depends on three things: SKU profile (how many distinct items, how fast each moves), pallet dimensions (standard 48"×40" GMA pallets vs oversize), and forklift fleet (counterbalance vs reach truck vs narrow aisle).
SKU velocity
High velocity SKUs (fast-moving) benefit from selective single-row racks where every pallet is directly accessible. Low velocity SKUs benefit from dense storage (double-deep, drive-in) because the time penalty of less-direct access matters less.
Density vs accessibility
This is the eternal trade-off. Double-deep packs ~30% more pallets per square foot than B2B selective, but each pallet is reachable only via the front pallet — so SKU selection slows down. Pick the configuration that matches your operations, not just your real estate.
Forklift class
Aisle width is dictated by your forklift fleet. Standard counterbalance wants 12 ft. Reach trucks want 8–9 ft. Turret trucks and very-narrow-aisle (VNA) trucks want 5–6 ft. If you can change the forklift, you can dramatically change the layout.
Any of these layouts can be built in RackCity in 15–30 minutes. We strongly recommend building three variants (B2B selective vs double-deep vs mixed) for any new warehouse, then picking based on the actual position counts and aisle compliance, not on intuition.
