Definition
The specific arrangement of cases, boxes, or other unit loads on a pallet deck to maximize stability, space utilization, and shipping efficiency. Common patterns include column stacking, interlocking (brick-lay), and pinwheel arrangements. Pallet pattern optimization software calculates the best configuration based on product dimensions, pallet size, weight limits, and trailer dimensions. An efficient pallet pattern minimizes wasted space and reduces shipping costs.

Unit Load
A quantity of goods assembled and secured on a pallet to form a single handling unit for storage and transportation. The unit load concept is fundamental to modern logistics — by consolidating individual items into pallet-sized units, material handling efficiency is dramatically improved. A well-built unit load is stable, within weight limits for the pallet and handling equipment, and configured to maximize trailer or container space utilization.
Pallet
A flat transport structure, typically made of wood, that supports goods in a stable fashion while being lifted by a forklift, pallet jack, or other jacking device. Pallets are the foundation of modern material handling and logistics, enabling efficient storage, stacking, and transportation of goods. The most common pallet size in North America is the 48x40 inch GMA pallet.
Overhang
The portion of a product load that extends beyond the edges of the pallet deck. Excessive overhang creates stability risks, can cause product damage during handling, and may prevent proper racking. Industry best practices recommend no more than one inch of overhang on any side. Overhang also refers to wing pallet designs where the deck boards intentionally extend past the stringers to support specific product dimensions.
Payload
The total weight of the goods placed on a pallet, excluding the weight of the pallet itself. Payload capacity is determined by the lesser of the pallet's load rating and the handling equipment's lifting capacity. Maximizing payload per pallet while staying within weight limits is a key objective in logistics optimization. Payload weight must also be considered in relation to trailer weight limits and road transport regulations.
