Pallet & Container Calculator
Calculate cases per pallet and pallets per container with weight and cube utilization checks.
Pallet & Container Calculator
Enter case dimensions and weight to compute how many cases fit on a pallet by layer, then how many pallets fit in a standard container or trailer. Tries both case orientations (normal and rotated 90°) and picks whichever fits more per layer. Includes standard presets for 20′ and 40′ ISO containers, 40′ and 45′ high-cube containers, and 53′ and 48′ domestic trailers. Weight limits are checked at both the pallet and vehicle level. Imperial and metric units. Results export to CSV.

How Pallet Loading Is Calculated
Pallet loading uses floor-division math: divide the pallet length by the case length to get cases per row, multiply by cases per column (pallet width divided by case width), and that gives you cases per layer. Stack layers until you hit the maximum stack height or the pallet weight limit, whichever comes first. This tool checks both the normal and rotated (90°) case orientations and picks whichever fits more per layer. The result is a conservative estimate — real warehouse operations may achieve slightly different counts depending on case rigidity, shrink-wrap overhang, and stacking patterns.
Standard Container and Trailer Dimensions
The six presets cover the most common shipping configurations: 20-foot and 40-foot ISO containers for ocean freight, 40-foot and 45-foot high-cube containers for volume-heavy imports, and 53-foot and 48-foot domestic trailers for North American truck freight. Each preset uses approximate internal usable dimensions after structural walls and corrugation. Actual usable space varies by container age and manufacturer — always confirm with your carrier or freight forwarder for binding load plans.
Why Cube Utilization Matters
In LTL and ocean freight, you pay for space even when the container is not full. Low cube utilization means you are shipping air. Improving pallet patterns — adjusting case orientation, optimizing layer counts, or switching to a higher-cube container — directly reduces per-unit freight cost. Pair this calculator with the NMFC Freight Class Estimator for density-based LTL class and the Landed Cost Calculator to see how freight flows into per-unit cost.
Automating Load Planning
For production use, pallet patterns and container loading should live in your item master — every SKU carries its case dimensions, Ti×Hi (cases per layer × layers), and pallet weight, and every outbound order or inbound PO automatically computes pallet counts and vehicle requirements. I build warehouse and logistics tools that embed this math into WMS workflows, purchase order planning, and freight cost allocation.
