When planning international shipping from China to Australia, understanding container sizes is extremely important because the dimensions directly affect cargo capacity, shipping costs, loading efficiency, and transportation planning. Whether you are shipping furniture, machinery, electronics, or Amazon FBA cargo, choosing the right container size can help reduce freight costs and avoid unnecessary delays.
In this article, we’ll explain standard shipping container dimensions, container types, internal measurements, payload capacities, and how to choose the right container for your shipment.
1. Types of Shipping Containers
Different cargo types require different container solutions. Before booking shipments from China to Australia, you need to check container load capacity, weight limits and door opening dimensions, confirm whether oversized goods require special handling equipment, and figure out how container specifications impact overall shipping costs.
We’ll cover popular container types for China-to-Australia imports below.
2. Standard Shipping Container Sizes
The most commonly used shipping containers in shipping from China to Australia are:
| Container Type | External Length | External Width | External Height |

| 40ft Container | 40 ft (12.19m) | 8 ft (2.44m) | 8.5 ft (2.59m) |
| 40ft High Cube | 40 ft (12.19m) | 8 ft (2.44m) | 9.5 ft (2.89m) |
| 45ft High Cube | 45 ft (13.72m) | 8 ft (2.44m) | 9.5 ft (2.89m) |
These are international ISO standard container sizes widely used in ocean freight shipping.
2.1 20ft Shipping Container Dimensions
The 20ft container is one of the most popular choices for small and medium cargo shipments in shipping from China to Australia.
20ft Container Internal Dimensions
| Measurement | Size |
| Internal Length | 5.9m |
| Internal Width | 2.35m |
| Internal Height | 2.39m |
| Door Width | 2.34m |
| Door Height | 2.28m |
| Capacity | Approximately 28 CBM |
| Max Payload | Around 28,000 kg |
Best Uses for 20ft Containers
A 20ft container is suitable for:
- Heavy cargo
- Machinery
- Tiles and stone products
- Furniture
- Small commercial shipments
As the high payload capacity,, many importers involved in import from China to Australia use 20ft containers for dense cargo.
While the container has a maximum payload of around 28 tonnes, the gross vehicle weight limit for road transport in Australia imposes further restrictions.
2.2 40ft Shipping Container Dimensions
The 40ft container provides double the length of a 20ft container while maintaining the same width and height.
40ft Container Internal Dimensions
| Measurement | Size |
| Internal Length | 12.03m |
| Internal Width | 2.35m |
| Internal Height | 2.39m |
| Door Width | 2.34m |
| Door Height | 2.28m |
| Capacity | Approximately 60 CBM |
| Max Payload | Around 26,000 kg |
Best Uses for 40ft Containers
40ft containers are ideal for:
- Large-volume cargo
- Consumer goods
- Furniture shipments
- Retail inventory
- Amazon FBA cargo
If your cargo is lightweight but bulky, a 40ft container is often more cost-effective.
2.3 40ft High Cube Container Dimensions
A High Cube container is similar to a standard 40ft container but taller.
40ft High Cube Internal Dimensions
| Measurement | Size |
| Internal Length | 12.03m |
| Internal Width | 2.35m |
| Internal Height | 2.69m |
| Door Width | 2.34m |
| Door Height | 2.58m |
| Capacity | Approximately 67 CBM |
| Max Payload | Around 26,000 kg |
The extra height provides about 7 CBM additional cargo space.
Best Uses for High Cube Containers
High Cube containers are commonly used for:
- Large furniture
- Lightweight bulky goods
- Industrial equipment
- E-commerce shipments
- Oversized cartons
These containers are widely used in shipping China to Australia when cargo volume is high.
3. Special Shipping Container Types and Dimensions
Besides standard containers, there are several special container types designed for specific cargo commonly seen in sea freight from China to Australia.
3.1 Open Top Container
Open Top containers have removable roofs for loading oversized cargo from above.
Common Uses
- Heavy machinery
- Construction equipment
- Industrial cargo
3.2 Flat Rack Container
Flat Rack containers have collapsible sides and are designed for oversized cargo.
Common Uses
- Vehicles
- Pipes
- Large machinery
- Steel structures
3.3 Refrigerated Container (Reefer)
Reefer containers maintain controlled temperatures for perishable products.
Common Uses
- Food
- Pharmaceuticals
- Frozen cargo
3.4 Tank Container (ISO Tank)
Tank containers are specially designed for transporting liquid, chemical, and food-grade products. Built with a stainless-steel tank enclosed within a standard ISO frame, they can be handled and transported using the same equipment as regular shipping containers.
Common Uses
- Chemicals
- Petroleum products
- Edible oils
- Wine and beverages
- Liquid food products
- Hazardous liquids
4. Shipping Container Door Dimensions
Many importers focus only on internal dimensions, but door size is equally important for smooth shipping from China to Australia.
Here are standard container door dimensions:
| Container Type | Door Width | Door Height |
| 20ft Standard | 2.34m | 2.28m |
| 40ft Standard | 2.34m | 2.28m |
| 40ft High Cube | 2.34m | 2.58m |
If cargo cannot fit through the door opening, it cannot be loaded even if internal space is sufficient.
5. How Many Pallets Fit in a Shipping Container?
This is another common logistics question for businesses involved in import from China to Australia.
| Container Type | Euro Pallets | Standard Pallets |
| 20ft Container | 11-24 pallets | 10-20 pallets |
| 40ft Container | 24-48 pallets | 22-44 pallets |
| 40ft High Cube | 24-48 pallets | 22-44 pallets |
Actual pallet quantity depends on pallet size and loading method.
6. How to Choose the Right Shipping Container Size
When deciding which container to use for China to Australia shipping, consider the following:
6.1 Cargo Volume
Measure the total CBM (cubic meters) of your shipment.
- Under 15 CBM → LCL shipping may be suitable
- 15–28 CBM → 20ft container
- 28–68 CBM → 40ft container
- Large bulky cargo → High Cube container
6.2 Cargo Weight
Familiarize yourself with container weight specifications and payload limits to avoid overloading, fines and shipping delays. Heavy goods such as tiles, steel products and machinery may hit weight limits before the container is fully loaded. For such shipments, a 20ft container is the more reliable option for ship from China to Australia.
6.3 Cargo Dimensions
Learn the external and internal measurements of 20ft and 40ft containers to maximize space usage and ensure smooth loading. Confirm the allowable load quantity, pallet capacity and cargo height to comply with inland transportation regulations.
For oversize items, use Open Top or Flat Rack containers. Verify cargo length, width, height and door clearance in advance.
