Reference Data
Container Size Reference
This table shows internal dimensions, CBM capacity, max payload and door size for commonly used ISO 668 general-purpose dry containers — a reference for planning how your cargo will fit.
| Container | Internal L×W×H (m) | Capacity (CBM) | Max payload (kg) | Door W×H (m) |
|---|---|---|---|---|
| 20ft Standard (Dry) | 5.9 × 2.35 × 2.39 | 33.2 m³ | 21,700 | 2.34 × 2.28 |
| 40ft Standard (Dry) | 12.03 × 2.35 × 2.39 | 67.7 m³ | 26,580 | 2.34 × 2.28 |
| 40ft High Cube (40HQ) | 12.03 × 2.35 × 2.69 | 76.3 m³ | 26,330 | 2.34 × 2.58 |

Plotted from the same ISO 668 reference capacities listed in the table above. Actual usable capacity is always lower than the theoretical figure once pallets, dunnage and load plan are taken into account.

Frequently Asked Questions
What's the difference between a 40ft standard and a 40HQ container?
They share the same length and width, but a 40HQ (High Cube) is about 30cm taller, giving roughly 8.6 more CBM of usable volume — useful for light, bulky cargo that runs out of space before it hits the weight limit.
Can I actually load cargo up to the maximum payload figure?
Not always in practice — road weight limits, packing method, and how the cargo is distributed inside the container can restrict this before you reach the container's rated maximum payload. Plan with a buffer and confirm with TGF for your specific cargo and route.
