External, internal, doors and capacity — plus the high cube comparison, since headroom is the spec people forget.
| Container | External L×W×H | Internal L×W×H | Door W×H | Capacity |
|---|---|---|---|---|
| 10ft Containers | 2.99m × 2.44m × 2.59m | 2.83m × 2.35m × 2.39m | 2.34m × 2.28m | 16m³ |
| 20ft Containers | 6.06m × 2.44m × 2.59m | 5.90m × 2.35m × 2.39m | 2.34m × 2.28m | 33.2m³ |
| 40ft Containers | 12.19m × 2.44m × 2.59m | 12.03m × 2.35m × 2.39m | 2.34m × 2.28m | 67.7m³ |
| 40ft High Cube | 12.19m × 2.44m × 2.90m | 12.03m × 2.35m × 2.69m | 2.34m × 2.58m | 76.4m³ |
Door height is lower than internal height — tall gear must clear 2.28m on a standard unit, not 2.39m. Internal width of 2.35m fits a car, but door-opening room is snug. And a high cube's extra 30cm is the difference between storage and a space you can genuinely work inside — see the high cube page.
