How Wide is a Shipping Container?
Shipping container width is one of the most important dimensions to understand when planning storage, transport, or site layout. Whether you're moving freight, setting up a worksite, or buying a container for storage, knowing the exact width helps avoid costly mistakes. Standard container sizes—10ft, 20ft, and 40ft are designed with consistent width measurements, making them predictable and easy to plan around. In this guide, we’ll break down the exact widths of each container type and explain how those dimensions impact real-world use.
Understanding Shipping Container Dimensions
Shipping containers are built to strict international standards, which ensures they can be transported seamlessly across ships, trucks, and rail systems worldwide. These standards are set by ISO (International Organization for Standardization), meaning a container built in one country will match dimensions used globally.
Containers are measured in three key ways: length, width, and height. Width is especially important for access, loading, and spatial planning. It’s also critical to distinguish between external and internal dimensions. External width determines how much space the container takes up on-site or during transport, while internal width defines how much usable space you have inside.
Small differences between these measurements due to wall thickness and structural components can impact what fits inside, particularly when loading pallets or equipment.

Standard Shipping Container Sizes Overview
The most common shipping container sizes are 10ft, 20ft, and 40ft. While these vary significantly in length, they all share a consistent width, which is a key advantage when planning logistics or storage layouts.
Most standard containers have the same external width, regardless of length. There are also high-cube containers, which are taller than standard units but maintain the same width. This consistency allows for easy stacking, transport, and compatibility across different systems.

How Wide is a 20ft Shipping Container
A standard 20ft shipping container has an external width of 8 feet (2.44 metres) and an internal width of approximately 7 feet 8 inches (2.35 metres). The slight reduction internally is due to the corrugated steel walls and structural framing.
This width is ideal for transporting palletised goods, as it comfortably fits standard Australian pallets side-by-side with minimal wasted space. It’s also a popular choice for general storage, tools, and equipment due to its balance of size and practicality.
High-cube 20ft containers are available, but while they offer extra height, the width remains the same. This consistency means you can plan layouts confidently regardless of the container variant.
Whether you need standard or high cube variants, you can explore our 20ft shipping containers to find the right fit.
How Wide is a 40ft Shipping Container
A 40ft shipping container has the same width as a 20ft unit, with an external width of 8 feet (2.44 metres) and an internal width of around 7 feet 8 inches (2.35 metres).
The key difference is length not width. A 40ft container simply doubles the internal space, making it ideal for high-volume storage, large-scale freight, or long-term site setups. Because the width is unchanged, loading processes remain consistent with 20ft containers, which simplifies logistics.
This uniformity allows businesses to scale up capacity without needing to adjust handling equipment or loading strategies.

How Wide is a 10ft Shipping Container
A 10ft shipping container follows the same width standard as larger containers, with an external width of 8 feet (2.44 metres) and an internal width of approximately 7 feet 8 inches (2.35 metres).
Despite its shorter length, the full-width design makes it highly practical for tight spaces where access and usability still matter. These containers are commonly used for small job sites, residential storage, or situations where space is limited but standard pallet access is still required.
Some 10ft units come in modified forms, such as side-door or custom storage solutions, but the width generally remains consistent across variations.

Container Width Variations: Standard vs. High-Cube
Container width does not change between standard and high-cube models. Both maintain the same external width of 8 feet (2.44 metres), ensuring compatibility across transport and storage systems.
The only difference with high-cube containers is height they are typically one foot taller. This added vertical space is useful for bulky goods but does not impact how much horizontal space you have.
Specialised containers such as side-door, refrigerated, or bulk units also generally follow the same width standard, though internal layouts may vary slightly depending on their purpose.

Why Container Width Matters for Your Business
Container width directly affects how efficiently you can use the space. It determines how many pallets fit across, whether machinery can be stored inside, and how accessible items are during loading and unloading.
For businesses, this impacts everything from transport efficiency to site layout planning. A consistent width makes it easier to design workflows, stack containers, and optimise storage systems.
Understanding width alongside length and height ensures you’re making the most of your available space and avoiding costly miscalculations.
Choosing the Right Container Width for Your Needs
Since container width is standard across most sizes, choosing the right unit comes down to how much space you need overall. Consider total volume, weight capacity, and how the container will be transported or accessed on-site.
A 10ft unit may suit tight areas, while 20ft and 40ft containers are better for larger storage or freight needs. The consistent width means you can scale up without changing your setup.
