Mixed shipments often contain several carton sizes, which makes a single length × width × height calculation inaccurate. This manifest-style tool calculates each carton group separately and adds the total cube.
How to use this calculator
Choose centimetres or inches, then add each carton size with its quantity. Use separate rows whenever outside dimensions differ, even if the products are related.
Formula and method
Each row is converted to cubic metres independently: length × width × height × quantity. The row CBMs are then summed into one shipment total.
Worked example
Ten 50 × 40 × 30 cm cartons and six 60 × 45 × 35 cm cartons are calculated as two separate volume groups rather than one averaged carton.
What to check before you ship
The result is shipment cube only. Pallets, loading gaps, door restrictions, stackability and payload can reduce usable vehicle or container capacity.
Why the result matters
Accurate dimensions and weights help with quoting, space planning and avoiding preventable adjustments. Always use the packaged outside dimensions that will actually be tendered for transport, and verify any carrier-specific rules that affect billing or classification.
