Understanding Shipping Containers
Shipping containers are rugged steel boxes designed for efficient handling and transport across sea, rail, and road. In logistics, three key terms help clarify their utility:
-
Size refers to the length (commonly 20 ft or 40 ft).
-
Internal Dimensions tell you how much usable cargo space is inside (length × width × height in meters).
-
Volume measures that space in cubic meters (m³).
These details are vital for selecting the right container to optimize cost, manage cargo accurately, and ensure safe delivery.
Container Types
Dry Containers (Standard)
Standard dry containers are the workhorses of global shipping. They feature fully enclosed sides and roof, offering reliable protection for general cargo such as electronics, furniture, and packaged goods. Common in both 20‑foot and 40‑foot lengths, they balance security, efficiency, and versatility, making them a staple in freight logistics.
| Size | Internal (L × W × H) | Volume |
|---|---|---|
| 20 ft | 5.90 m × 2.35 m × 2.39 m | 33 m³ |
| 40 ft | 12.03 m × 2.35 m × 2.39 m | 67 m³ |
High Cube Containers
High Cube containers offer roughly one extra foot of internal height compared to standard dry containers, allowing for significantly more cubic space without increasing the unit’s footprint. This makes them especially suitable for light, bulky cargo that benefits from extra vertical clearance, such as furniture, palletized goods, or retail stock. The additional height also supports versatile uses like storage conversions, mobile offices, or on-site workshops.
| Size | Internal (L × W × H) | Volume |
|---|---|---|
| 40 ft | 12.03 m × 2.35 m × 2.70 m | 76 m³ |
| 45 ft | 13.56 m × 2.35 m × 2.70 m | 85 m³ |
Open Top Container
Open top containers feature a removable roof that enables vertical loading of oversized or oddly shaped cargo that cannot fit through side doors. They are ideal for heavy machinery, sculptures, or construction materials, allowing cranes or loaders to place objects directly from above while still providing side-door flexibility for unloading.
| Size | Internal (L × W × H) | Volume |
|---|---|---|
| 20 ft | 5.90 m × 2.35 m × 2.38 m | 32.5 m³ |
| 40 ft | 12.03 m × 2.35 m × 2.38 m | 66.4 m³ |
Flat Rack Container
Flat rack containers are open on the top and sides, usually equipped with fixed or foldable end walls. They excel at transporting irregularly shaped or heavy cargo such as vehicles, pipes, and large industrial components. Newer flat racks can handle static payloads up to 50 000 kg and collapse for space-saving storage when empty.
| Size | Internal (L × W × H) | Volume |
|---|---|---|
| 20 ft | 5.94 m × 2.35 m × 2.24 m | 32.7 m³ |
| 40 ft | 11.66 m × 2.37 m × 2.28 m | 62 m³ |
Reefer Container (Refrigerated)
Refrigerated containers (reefers) come with built-in temperature control that can range from −65 °C to +40 °C. They are used for preserving perishable items such as fruits, pharmaceuticals, seafood, and dairy. Reefers rely on external power through ships or gen-sets and support crucial cold chain logistics for global
| Size | Internal (L × W × H) | Volume |
|---|---|---|
| 20 ft | 5.45 m × 2.29 m × 2.25 m | 28 m³ |
| 40 ft | 11.58 m × 2.29 m × 2.50 m | 67 m³ |
