Cube Utilization

Cube utilization is a metric that measures how effectively the available cubic space in a container, trailer, or warehouse is being used. Higher utilization means more efficient use of space and typically lower per-unit shipping costs.

Calculating Cube Utilization

Cube Utilization = (Volume Used ÷ Total Available Volume) × 100

Example:

• Trailer capacity: 3,000 cubic feet
• Cargo volume: 2,400 cubic feet
• Utilization = (2,400 ÷ 3,000) × 100 = 80%

Benchmarks

Why Cube Utilization Matters

Transportation

• More product per shipment
• Lower cost per unit
• Fewer trips needed
• Reduced carbon footprint

Warehousing

• More inventory capacity
• Lower storage costs
• Delayed facility expansion
• Better ROI on space

Improving Cube Utilization

Packaging

• Right-size boxes
• Eliminate unnecessary packaging
• Use flexible packaging when possible
• Stack products efficiently

Loading

• Optimize load patterns
• Use vertical space
• Fill gaps with smaller items
• Consider double-stacking pallets

Planning

• Consolidate shipments
• Mix compatible products
• Plan loads in advance
• Use load planning software

Cube vs. Weight Limitations

Sometimes you “cube out” (fill space) before you “weigh out” (hit weight limit):

• Light, bulky products cube out
• Heavy, dense products weigh out

Optimal loads balance both dimensions.
