Enter box dimensions and quantity for total cubic metres and an estimated container load.
Cubic metres. Length × width × height in metres is one box's CBM; multiply by quantity for the total. Sea freight is usually priced on it, and it decides whether you book a whole container (FCL) or share one (LCL).
A 20ft container holds about 33 m³ nominally, but boxes never pack perfectly — pallets, corners and door clearance eat space. In practice 80–85% is the usable limit; this calculator uses 85%. Uniform boxes fit more, mixed sizes less.
Air freight charges whichever is greater: actual or volumetric weight. The standard conversion is 1 m³ = 167 kg. Light, bulky cargo is billed on volume.
Yes. Roughly 28 t for 20ft and 26.5 t for 40ft. Heavy cargo hits the weight cap before the volume runs out. Enter weight per box to see the total.
Use the pallet footprint (e.g. 1100×1100) and the stacked height as the box. Pallets often can't double-stack, so real counts drop further.
Forwarders apply their own rounding and minimum-CBM rules. This gives physical volume only — use it to size the shipment before asking for quotes.
