Calculate each package in metres
Multiply packed length by width by height to obtain cubic metres, often written as CBM. An illustrative carton measuring 1.20 m × 0.60 m × 0.50 m occupies 0.36 m³. Ten identical cartons total 3.60 m³. These figures demonstrate arithmetic only; they are not freight prices or a promise of how much furniture will fit into a particular container.
Count every package and avoid double counting
Use a separate line for each package type, with quantity and external measurements. If one table ships in two cartons, include both cartons rather than using the assembled table size. For ten table tops packed at 1.20 m × 0.80 m × 0.15 m, the total is 1.44 m³. Add the bases and fittings according to their actual packing; do not assume they occupy no additional space.
Understand why total CBM is not a loading plan
Two orders with the same calculated volume may load differently. Shape, stacking restrictions, heavy pieces, fragile surfaces and access to the container door can affect the arrangement. Pallets or crates may change both volume and weight. Ask the logistics provider to review the package information and proposed loading method rather than treating nominal container capacity as guaranteed usable space.
Request a quotation with clear assumptions
Provide collection and delivery locations, package count, dimensions, gross weights, readiness date and handling requirements. Ask which services, surcharges and destination work the quotation includes. The provider should explain its charging basis for the proposed service. Compare like-for-like scopes and confirm the validity period; a CBM calculation by itself cannot determine the full delivered cost.
Project checklist
What to prepare
- External packed measurements in one consistent unit.
- Package quantities, gross weights and stacking restrictions.
- Separate figures for estimated and confirmed packing.
- A freight quotation stating inclusions, exclusions and validity.
A useful question
Will flat-pack furniture always cost less to deliver?
It may reduce packed volume, but compare the complete result. Extra packaging, destination assembly, labour, fittings and damage risk can change the calculation. Ask for both packing options and assess them against the installation plan, not just the smallest CBM figure.
