CBM Formula

CBM = Length (m) × Width (m) × Height (m) × Quantity
  • Standard pallet capacity: 1.728 CBM (1.2m × 1.0m × 1.44m stacking height)
  • Container capacities are usable volume estimates — actual cargo may vary
  • For LCL ocean freight, you are charged per CBM or per 1,000kg (whichever is greater)

Quick Reference: Container & Pallet Capacities

20ft Container

~25 CBM usable / ~21,700 kg max payload

  • Internal: 5.9m × 2.35m × 2.39m
  • Typical LCL cutoff: 15 CBM
  • Best for: 10–15 pallets

40ft Standard Container

~55 CBM usable / ~26,500 kg max payload

  • Internal: 12.03m × 2.35m × 2.39m
  • Typical LCL cutoff: 35 CBM
  • Best for: 20–24 pallets

40ft High-Cube Container

~67 CBM usable / ~26,500 kg max payload

  • Internal: 12.03m × 2.35m × 2.69m
  • Extra 0.30m height vs standard
  • Best for: tall or palletized cargo

Standard Pallet (NA)

1.2m × 1.0m base

  • Typical stack height: 1.44m
  • Volume: ~1.73 CBM
  • Max weight: 1,000–1,500 kg

Frequently Asked Questions

What is CBM and how is it calculated?

CBM stands for cubic metre — the standard unit of volume used in international freight and warehousing. It is calculated as: CBM = Length (m) × Width (m) × Height (m) × Quantity. For dimensions in centimetres, divide each dimension by 100 before multiplying.

How many CBM fit on a standard pallet?

A standard Euro pallet (1.2m × 0.8m) stacked to a typical 1.5m height holds approximately 1.44 CBM. A North American pallet (1.2m × 1.0m) at 1.44m height holds approximately 1.73 CBM. This calculator uses the North American standard.

How many CBM fit in a shipping container?

A 20ft standard container holds approximately 25–28 CBM of usable cargo space. A 40ft standard container holds approximately 55–58 CBM, and a 40ft high-cube holds approximately 67–68 CBM. Actual loading capacity depends on cargo density and how boxes stack.

How is ocean freight charged by CBM?

LCL (less-than-container-load) ocean freight is typically charged per CBM or per 1,000 kg (a metric ton), whichever is greater. For example, if your shipment is 3 CBM but weighs 4,000 kg, you would be charged for 4 CBM (since 4,000 kg / 1,000 = 4). This is called the revenue ton.
