Container Load Calculator
Estimate how your total shipment CBM compares with common 20 ft, 40 ft, and 40 ft high cube practical loading capacities.
When to use a container load estimate
- Importers comparing LCL and FCL planning options
- Exporters estimating whether cargo may fill a 20 ft, 40 ft or high cube container
- Warehouse teams checking loading loss before booking
- Small businesses preparing questions for a forwarder or loading team

Container utilisation assumptions
Estimated utilization = total shipment CBM / practical container CBM capacity x 100. Practical loading capacity is lower than the physical container volume because of cargo shape, packaging, handling gaps, and loading constraints.
Container utilisation example
A 29 CBM shipment planned for a 40 ft standard container with a practical capacity of 58 CBM uses about 50% of the container. Actual loading still depends on cargo shape, palletization, stacking and weight distribution.
Container loading risks to check
- Assuming theoretical container volume equals usable loading capacity
- Ignoring door clearance, pallet height or uneven carton shapes
- Checking CBM without reviewing weight limits and distribution
- Forgetting that irregular or non-stackable cargo can reduce usable space
FAQ
Can CBM alone confirm container fit?
No. CBM is a useful planning estimate, but actual loading depends on cargo shape, palletization, weight limits, stacking, packaging strength, and loading method.
What are common container CBM capacities?
Many teams use rough planning capacities such as 28 CBM for 20 ft, 58 CBM for 40 ft, and 66 CBM for 40 ft high cube after practical loading allowances.
Should I confirm with a warehouse?
Yes. Final loading plans should be confirmed by the warehouse, forwarder, or container loading team.
