Specialised Container Dimensions

Beyond standard dry containers, specialised containers serve unique cargo requirements.
Here are the dimensions for the most common specialised types.

Refrigerated (Reefer) Containers

Reefer containers feature built-in refrigeration units that maintain temperature-controlled environments from -30°C to +30°C. Internal dimensions are slightly smaller due to insulation.

Type Internal Length Internal Width Internal Height Capacity Tare Weight Payload
20ft Reefer 5,456 mm 2,288 mm 2,263 mm 28.2 m³ 2,810 kg 27,670 kg
40ft HC Reefer 11,590 mm 2,284 mm 2,544 mm 67.5 m³ 4,490 kg 30,510 kg

Open Top Containers

Open top containers have a removable tarpaulin or hard-top roof, allowing top-loading of oversized or heavy cargo using cranes.

Type Internal Length Internal Width Internal Height Roof Opening (L x W) Capacity Payload
20ft Open Top 5,898 mm 2,350 mm 2,348 mm 5,680 x 2,252 mm 32.5 m³ 28,240 kg
40ft Open Top 12,022 mm 2,350 mm 2,348 mm 11,798 x 2,230 mm 66.3 m³ 26,600 kg
40ft HC Open Top 12,032 mm 2,352 mm 2,653 mm 11,806 x 2,192 mm 75.1 m³ 28,610 kg

Flat Rack Containers

Flat rack containers have collapsible or fixed end walls with no side walls or roof. Designed for oversized, heavy, or irregularly shaped cargo.

Type Internal Length Internal Width Internal Height Capacity Tare Weight Max Load
20ft Flat Rack 5,668 mm 2,194 mm 2,213 mm 28.4 m³ 3,100 kg 35,000 kg
40ft Flat Rack 11,852 mm 2,208 mm 1,955 mm 53.2 m³ 6,200 kg 38,800 kg
40ft HC Flat Rack 11,658 mm 2,374 mm 2,264 mm 64.3 m³ 6,250 kg 52,500 kg

Understanding Container Weights

Container weight specifications are critical for safe transportation and compliance with road, rail, and maritime regulations.
Here are the key weight terms you need to know.

Tare Weight
2,150 - 4,650 kg

The weight of the empty container itself. A standard 20ft container weighs approximately 2,150 kg empty, while a 45ft HC weighs around 4,650 kg.

Max Payload
26,840 - 28,800 kg

The maximum weight of cargo the container can hold. This is the max gross weight minus the tare weight of the container.

Max Gross Weight
30,480 - 32,500 kg

The maximum total weight including both the container and its cargo. This is the absolute weight limit for safe handling and transport.

Important: While containers have a maximum payload capacity, actual loading limits may be further restricted by local road weight regulations, vessel stacking limits, or terminal equipment capacity. Always verify with your shipping line or transport provider.

How to Choose the Right Container Size

Selecting the right container depends on your cargo volume, weight, and specific requirements.
Use this guide to make the best choice.

Choose a 20ft Container When
  • Your cargo is heavy but doesn’t require much floor space
  • You’re shipping dense goods like machinery, metals, or building materials
  • Your shipment volume is under 33 m³
  • You need to stay within road weight limits for trucking
  • You’re shipping Less than Container Load (LCL) cargo
  • You’re consolidating multiple smaller shipments
Choose a 40ft Container When
  • You need to maximise cargo volume for lightweight goods
  • You’re shipping consumer goods, retail stock, or household items
  • Your shipment volume is between 33 – 67 m³
  • You want the most cost-effective option per cubic metre
  • You’re consolidating multiple smaller shipments
Choose a High Cube When
  • Your cargo exceeds 2.39m (7’10”) in height
  • You need to stack pallets higher for better space utilisation
  • You’re converting the container for accommodation or office use
  • You want extra overhead clearance for easier loading
  • Your goods are voluminous but lightweight

Frequently Asked Questions

Common questions about shipping container sizes, dimensions, and specifications.

What is the difference between a standard and High Cube container?

The only difference is height. A standard container has an external height of 8’6″ (2,591 mm), while a High Cube container stands at 9’6″ (2,896 mm). This extra foot of height translates to approximately 13% more cubic capacity. High Cube containers are marked with black and yellow striped tape near the corner castings for easy identification.

The 40ft High Cube (40HC) is the most widely used container in international shipping. It offers 76.2 m³ of cargo space and the extra foot of height compared to a standard 40ft container makes it versatile for a wide range of goods. The 20ft standard container is the second most common and serves as the basis for the industry-standard TEU (Twenty-foot Equivalent Unit) measurement.

A standard 20ft container can fit approximately 10-11 standard pallets (1,200 x 1,000 mm) loaded in a single layer. A 40ft container can accommodate approximately 20-21 standard pallets in a single layer. If using Euro pallets (1,200 x 800 mm), a 20ft container fits about 11 pallets and a 40ft fits about 23-24 pallets.

TEU stands for Twenty-foot Equivalent Unit and represents the cargo capacity of a standard 20ft container. FEU stands for Forty-foot Equivalent Unit and equals two TEUs. These are standard units used across the shipping industry to measure vessel capacity, port throughput, and trade volumes. For example, a vessel with a capacity of 10,000 TEU can carry 10,000 twenty-foot containers or 5,000 forty-foot containers.

Yes. Shipping container dimensions are standardised by the International Organization for Standardization (ISO) under ISO 668 and ISO 1496. This ensures containers are interchangeable across ships, trucks, and rail platforms worldwide. However, slight variations (typically 10-20mm) can occur between manufacturers, which is why dimensions are often given as approximate values.

The difference between internal and external dimensions accounts for the thickness of the container walls, floor, and roof. Standard steel container walls are approximately 2mm thick, but the corrugated steel panels and structural framing add to the total wall thickness. The floor typically includes marine-grade plywood (approximately 28mm thick) over steel cross-members, which reduces the internal height by about 200mm compared to the external height.

Absolutely. Shipping containers are widely used for on-site storage, workshops, offices, accommodation, cafes, and retail pop-ups. For storage, both new (one-trip) and used containers are suitable. For conversions, High Cube containers are preferred as they offer greater internal height for comfortable living and working spaces.
