Shipping Container Sizes in Metres: 10ft, 20ft and 40ft Dimensions Explained
Understanding shipping container sizes in metres makes it easier to choose the right container for storage, transport, construction, business operations or a container conversion project.
Shipping containers are commonly advertised in feet, including 10ft, 20ft and 40ft models. However, metric measurements are particularly useful when checking available space, planning delivery access, preparing foundations or comparing container dimensions with other structures.
In this guide, we explain the approximate external and internal dimensions of common shipping containers, compare standard and high-cube models, and highlight the measurements worth checking before purchasing.
Common Shipping Container Sizes in Metres
The most common shipping container lengths are 10ft, 20ft and 40ft. Their approximate external lengths are:
| Container size | Approximate length in metres |
|---|---|
| 10ft | 2.99m |
| 20ft | 6.06m |
| 40ft | 12.19m |
Most standard shipping containers are approximately 2.44 metres wide externally.
Standard-height containers are approximately 2.59 metres high, while high-cube containers are approximately 2.90 metres high.
These measurements are general industry dimensions. Actual specifications can vary depending on the manufacturer, container type and model.
1. 10ft Shipping Container Dimensions in Metres
A 10ft shipping container is one of the smaller commonly available container options.
Its compact footprint can make it useful for storage, equipment protection and situations where a larger container may not fit.
Approximate external measurements:
| Measurement | Approximate size |

Actual measurements can differ between models and manufacturers.
Common uses of a 40ft container
A 40ft container may be considered for:
- Larger storage requirements.
- Commercial inventory.
- Construction materials.
- Industrial equipment.
- Agricultural supplies.
- Container modification projects.
- Certain transport applications.
Before choosing this size, make sure there is sufficient space for delivery, positioning and access to the container doors.
4. Standard vs High-Cube Container Dimensions
One important difference when comparing shipping container sizes is the height.
A standard container and a high-cube container may have the same external length and width, but the high-cube model provides additional vertical space.
| Measurement | Standard container | High-cube container |
|---|---|---|
| External height | Approx. 2.59m | Approx. 2.90m |
| Height difference | — | Approx. 0.30m more |
| External width | Approx. 2.44m | Approx. 2.44m |
The extra height may be useful when storing taller equipment, stacking goods or planning certain container modifications.
High-cube models are particularly worth considering when internal headroom is important.
However, the actual internal height still depends on the container specification, flooring and any modifications.
5. Shipping Container Measurements: External vs Internal Dimensions
When comparing containers, it is important to understand the difference between external and internal measurements.
External dimensions describe the overall length, width and height of the container. These measurements are useful when checking site space, transport access and positioning requirements.
Internal dimensions describe the usable space inside the container. They are particularly important when calculating storage capacity or planning the placement of equipment and materials.
The internal dimensions are smaller because of:
- Side walls.
- Roof construction.
- Floor thickness.
- Door framing.
- Internal fittings.
- Insulation and modifications, where installed.
For example, a standard 20ft container may have an external length of approximately 6.06m but an internal length of around 5.90m.
Always use the actual container specification when planning a project.
6. Shipping Container Sizes Comparison Table
The following table summarises common dimensions for quick reference.
| Container | External length | External width | Standard external height |
|---|---|---|---|
| 10ft | Approx. 2.99m | Approx. 2.44m | Approx. 2.59m |
| 20ft | Approx. 6.06m | Approx. 2.44m | Approx. 2.59m |
| 40ft | Approx. 12.19m | Approx. 2.44m | Approx. 2.59m |
For high-cube models, the external height is approximately 2.90m.
The table provides general reference measurements. Special-purpose containers, older models and modified containers may have different dimensions.
7. How to Convert Shipping Container Sizes from Feet to Metres
Shipping container sizes are commonly described in feet. Converting these measurements into metres is straightforward.
The conversion is:
1 foot = 0.3048 metres
To convert a measurement in feet into metres, multiply the measurement by 0.3048.
Examples:
| Measurement in feet | Approximate measurement in metres |
|---|---|
| 8ft | 2.44m |
| 10ft | 3.05m |
| 20ft | 6.10m |
| 40ft | 12.19m |
| 45ft | 13.72m |
It is important to distinguish between converting a nominal container size and measuring the actual container.
For example, a container advertised as 20ft is a nominal size. Its commonly quoted external length is approximately 6.06m, rather than the exact mathematical conversion of 20ft, which is 6.096m.
This is why actual manufacturer or supplier specifications should always take priority when planning a project.
8. What Measurements Should You Check Before Buying?
Knowing the nominal container size is only the first step. Before purchasing, confirm the measurements that matter for your intended use.
External length and width
Check the overall dimensions to make sure the container will fit in the intended location.
External height
Allow enough overhead clearance for the container, delivery equipment and placement process.
Internal length and width
These measurements determine how much usable storage or working space is available.
Door opening dimensions
The door opening may be smaller than the internal width and height. This is particularly important when storing machinery, pallets or large equipment.
Floor height
The distance between the ground and container floor affects loading, unloading and access arrangements.
Weight
Container tare weight and maximum gross weight vary by model. Check the manufacturer’s or supplier’s specifications if weight matters for transport or installation.
Modified dimensions
If the container has been modified with insulation, internal walls, refrigeration equipment or other fittings, the usable dimensions may differ significantly from those of a standard model.
9. Allow Space for Delivery and Installation
A container may fit within the available land but still be difficult to deliver or position.
Before arranging delivery, check:
- Driveway width.
- Entry clearance.
- Turning space.
- Overhead power lines.
- Trees and branches.
- Ground stability.
- Slope and drainage.
- Available placement space.
- Access for the delivery vehicle and lifting equipment.
A 40ft container requires a substantially longer placement area than a 20ft container. However, the space required for delivery may be greater than the container’s own dimensions.
The delivery method and site conditions should be assessed before confirming an order.

10. Which Shipping Container Size Should You Choose?
The right container depends on what you intend to store, transport or build.
| Your requirement | Size worth considering |
|---|---|
| Compact storage | 10ft |
| General business storage | 20ft |
| Larger storage capacity | 40ft |
| Additional internal headroom | High-cube model |
| Container conversion project | Depends on the design and intended use |
A smaller container may be easier to position on a restricted property, while a larger container can provide more usable space.
However, choosing a container purely by length can lead to problems. Consider the internal measurements, door opening, container condition and delivery requirements as well.
