Measure the packing.
Then plan the load.

20GP or 40HQ?

A typical 20GP has about 33 m³ of internal volume; a typical 40HQ about 76 m³. These are approximate geometric capacities, not guaranteed usable furniture capacity. Confirm the specific carrier’s equipment dimensions and payload.

Door openings, non-stackable pieces, protective packing, loading gaps and weight limits reduce usable space. A volume total cannot establish that a shipment will fit. Ask for a loading plan based on the packed item list.
