Optimize box arrangement on pallets, calculate required pallets, and determine freight class from density
Pallet optimization determines the most efficient arrangement of boxes on a pallet. By testing different orientations and stacking heights, you can maximize boxes per pallet, minimize pallets needed, and understand the freight class impact of your configuration.
Select your pallet type (standard, euro, or custom), enter box dimensions and weight, specify how many boxes you're shipping, and set your maximum stack height. The calculator tests both orientations and shows which packs more efficiently.
Efficient pallet configurations reduce the number of pallets needed, lower total shipment weight, and directly impact freight class. Better configurations mean fewer pallets, lower freight costs, and sometimes better freight class rates.
Pallet optimization is just one step in reducing freight costs. Combine it with freight class calculation and DIM weight analysis for comprehensive shipment planning.

Common questions about pallet optimization and specifications
The most common pallet size in US warehousing and shipping is the GMA (Grocery Manufacturers Association) standard pallet: 48 × 40 inches. This pallet fits standard truck trailers and warehouse racking. Other common sizes include Euro pallets (47.2 × 31.5 inches / 1,200 × 800 mm) and custom industrial pallets. Always check with your carrier — standard pallet dimensions affect freight class and trailer load planning.
The industry standard maximum stack height for LTL freight is 72 inches (6 feet) total, including the pallet. This is based on typical forklift and racking height limitations. Some carriers accept up to 84 inches for certain commodity types, but going beyond 72 inches can trigger a Class 200+ classification for non-palletized freight and may require special handling fees.
Freight class is determined by density (weight ÷ volume). Better pallet configuration — fitting more boxes per layer, more layers per pallet — increases density and lowers the freight class. For example, reducing the freight class from Class 125 to Class 85 on a 2,000-lb shipment can save $100–$200 in LTL charges. Optimizing your pallet configuration is one of the most impactful ways to reduce LTL shipping costs.
A standard wood GMA pallet (48 × 40 inches) weighs approximately 30–35 lbs. When calculating freight class and total shipment weight, pallet weight must be included. For a shipment with 10 pallets, add approximately 300–350 lbs for pallet tare weight. Some carriers require pallet weight to be included on the BOL.
For US LTL shipping, standard 48 × 40 inch GMA pallets are strongly preferred. Euro pallets (47 × 31 inches) waste space in standard 48-inch-deep warehouse racks and standard 53-foot trailers, which are designed for 48 × 40 pallet pairs. Unless your customers specifically require Euro pallets, standardizing on GMA pallets reduces handling costs and maximizes trailer utilization.
