Container Loading Calculator | ContainerMetric

How to Use the Container Volume Calculator

Select the container type (e.g., 20ft Standard, 40ft Standard, or 40ft High Cube). The tool automatically loads standard internal dimensions.

Input custom dimensions if you are using specialized equipment like Flat Racks or Open Tops. The calculator provides results in both Cubic Meters (CBM) and Cubic Feet (CFT).

Note that 'Usable Volume' is typically 85-90% of the theoretical maximum due to irregular cargo shapes and the need for dunnage and air circulation.

Popular Logistics Scenarios

• Calculate CBM for LCL Shipment — Measure total cubic meters for your less-than-container-load cargo before booking with a freight forwarder.
• Optimize Pallet Loading for EUR Pallets — Calculate how many boxes stack per layer and how many layers fit on EUR1, EUR2, US, or Asia pallets.
• Calculate Total Shipment Gross Weight — Add box weight, product weight, pallet tare, and packing material to get the correct VGM for your shipment.
• Determine US LTL Freight Class — Enter shipment weight and volume to find your NMFC freight class and avoid unexpected LTL surcharges.
• Reefer Container Capacity at -18°C — Estimate how many boxes fit in a 20ft or 40ft refrigerated container at your required setpoint temperature.
• Compare DHL vs FedEx DIM Weight — Enter box dimensions to compare dimensional weight and chargeable weight across major international couriers.
• Verify Container Center of Gravity — Place multiple cargo items in a container and confirm the center of gravity stays within safe transport limits.
