How Tall Is a Shipping Container? Standard and High Cube Heights Explained
If you are planning to buy, transport or modify a shipping container, knowing how tall a shipping container is can help you choose the right unit for your project. Container height affects storage capacity, delivery access, installation clearance and the amount of usable internal space.
Most standard shipping containers are approximately 2.59 metres (8ft 6in) tall externally. High cube shipping containers are taller, measuring approximately 2.90 metres (9ft 6in) externally.
Although the difference is only about 30 centimetres, the extra height can be useful when storing taller equipment, loading goods or planning a container conversion.
This guide explains standard and high cube container heights, internal clearance, common container dimensions and what to check before arranging delivery in Australia.

How Tall Is a Standard Shipping Container?
A standard shipping container is approximately 2.59 metres (8ft 6in) high externally.
This is a common height for standard 20ft and 40ft general-purpose freight containers.
The external height includes the roof and floor structure. Therefore, the usable internal height is lower.
A typical standard-height container has an internal height of approximately 2.39 metres, although the actual measurement depends on the container model and construction.
Standard shipping container height measurements
| Measurement | Approximate height |
|---|---|
| External height | 2.59 metres |
| External height in feet | 8ft 6in |
| Typical internal height | 2.39 metres |
| Typical internal height in feet | 7ft 10in |
These are indicative dimensions for common general-purpose containers. Always confirm the specifications of the actual unit before purchasing.
If you are comparing different container lengths, read our Shipping Container Sizes in Meters guide.
How Tall Is a High Cube Shipping Container?
A high cube shipping container is approximately 2.90 metres (9ft 6in) high externally.
This makes it around 30 centimetres taller than a standard-height container.
High cube containers are designed to provide additional vertical space. They can be useful for storing taller goods, accommodating certain equipment or planning container-based workspaces and conversions.
High cube shipping container height measurements
| Measurement | Approximate height |
|---|---|
| External height | 2.90 metres |
| External height in feet | 9ft 6in |
| Typical internal height | 2.67 metres |
| Typical internal height in feet | 8ft 9in |
The internal measurement is indicative and varies between models.
If extra internal clearance is important for your project, check the manufacturer’s or supplier’s specification sheet rather than relying only on the high cube label.
Standard vs High Cube Shipping Container Heights
The main difference between a standard and high cube shipping container is the external height and the additional internal clearance.
| Feature | Standard container | High cube container |
|---|---|---|
| External height | 2.59 m | 2.90 m |
| External height in feet | 8ft 6in | 9ft 6in |
| Typical internal height | 2.39 m | 2.67 m |
| Extra external height | — | About 0.30 m |
Which container provides more space?
A high cube container provides additional vertical clearance. This can make it more suitable for taller equipment, stacked goods and certain conversion projects.
However, a taller container is not automatically the best option. You also need to consider the available installation height, delivery access, loading requirements and the total cost.

Internal Height vs External Height
Understanding the difference between internal and external container height is important when choosing a unit.
External container height
External height measures the distance from the bottom of the container’s supporting structure to the top of its roof.
This measurement is important when checking:
- Overhead clearance at the property.
- Access through gates and covered areas.
- Transport restrictions.
- Installation height.
- Clearance beneath structures and power lines.
For example, a standard container measuring approximately 2.59 metres externally needs more than 2.59 metres of available clearance if it must pass beneath an obstruction.
Additional clearance may be required during lifting and positioning.
Internal container height
Internal height refers to the usable vertical space inside the container.
It is lower than the external height because the roof structure and floor construction take up space.
For a standard container, the typical internal height is approximately 2.39 metres. A high cube model commonly provides around 2.67 metres of internal height.
Door opening height
The door opening can also be lower than the internal ceiling height.
This matters when loading tall machinery, equipment, furniture or packaged goods.
Before purchasing, compare the height of your largest item with the actual door opening. Allow enough clearance for safe loading and unloading.
Does Container Length Affect Its Height?
Container length and height are separate specifications.
A standard 20ft container and a standard 40ft container generally have the same external height. The same principle applies to many high cube models.
| Container type | Approximate external length | Approximate external height |
|---|---|---|
| 20ft standard | 6.06 m | 2.59 m |
| 40ft standard | 12.19 m | 2.59 m |
| 20ft high cube | 6.06 m | 2.90 m |
| 40ft high cube | 12.19 m | 2.90 m |
These are common nominal dimensions for general-purpose containers. Specialist, modified and domestic units can differ.
If you need a smaller storage footprint, explore our 10ft shipping containers. For larger storage requirements, compare our 20ft container range.
What Affects the Usable Height Inside a Shipping Container?
The nominal external height does not tell you everything about the space available inside.
Several factors can affect usable internal clearance.
1. Floor construction
Container floors have a thickness that reduces the internal height compared with the outside measurement.
Additional flooring or raised platforms can reduce the available clearance further.
2. Roof structure
The roof and supporting structure occupy space above the internal area. This is one reason internal height is lower than external height.
3. Insulation and lining
If a container is converted into an office, cabin or other enclosed space, insulation and internal lining can reduce the usable height.
This is especially important when planning a container home or workspace.
Read our Shipping Container Home Insulation Guide Australia before deciding on a conversion design.
4. Internal equipment
Shelving, ventilation equipment, lighting, air-conditioning units and other fittings can affect available headroom.
Plan their positions before completing the fit-out.
5. Previous modifications
Some containers have raised floors, additional linings, refrigeration equipment or other modifications. Their usable internal measurements may differ from those of a standard general-purpose container.
For modified units, request the exact internal measurements before ordering.
How to Choose the Right Shipping Container Height
The right height depends on what you intend to store or build.
Choose a standard-height container for general storage
A standard container may be suitable for general stock, tools, equipment, furniture and many business storage applications.
If your stored goods fit comfortably within the internal dimensions, the extra height of a high cube may not be necessary.
Choose a high cube container for taller goods
A high cube model may be worth considering when storing tall machinery, bulky equipment or goods that need extra vertical clearance.
It can also provide more internal headroom for certain container conversions.
Consider high cube containers for conversion projects
If you are planning a container office, workshop, cabin or other modified structure, additional ceiling clearance may be useful.
However, insulation, ceiling linings, flooring and service installations can reduce the final internal height.
Explore our container modification options when planning a customised project.
Check the total site height
Before ordering a high cube container, check the available space at the installation location.
Consider overhead structures, power lines, tree branches, covered driveways and any restrictions that may affect delivery or lifting.
Shipping Container Delivery and Installation Clearance
Container height is not only important inside the unit. It also affects transport and installation planning.
A container may fit into its intended location once positioned but still be difficult to deliver if the access route has insufficient clearance.
Before arranging delivery, check:
- The actual external container height.
- The height of gates and covered entrances.
- Overhead power lines and other obstructions.
- The access road and available turning space.
- Ground conditions and the proposed foundation.
- Additional clearance needed for lifting and positioning.
Do not measure only the final resting position. The delivery vehicle, lifting equipment and installation method can require additional space.
