40ft High Cube Containers Felixstowe
Why choose a 40ft high cube container?
A 40ft high cube is useful when the length of a standard 40ft container suits the job, but vertical clearance is tight. The external height is approximately 9ft 6in rather than about 8ft 6in for a standard container, giving roughly an extra foot of height.
That difference can matter with tall machinery, stacked stock, large cartons, racking or equipment that needs greater door clearance. It can also provide useful headroom where a container is being considered for a suitable conversion, subject to the proposed work and planning requirements.
The extra height is only worthwhile if you can use it. If the goods fit comfortably inside a standard unit, compare the high cube with a 40ft shipping container. If the storage requirement is considerably smaller, a 20ft shipping container may take up less site space.

40ft high cube container dimensions
Published specifications vary slightly between manufacturers and individual containers. The figures below are useful for planning, but they should not replace the specification of the actual unit being supplied.
| 40ft high cube | Approximate metric size | Approximate imperial size |
|---|---|---|
| External length | 12.19m | 40ft |
| External width | 2.44m | 8ft |
| External height | 2.89m to 2.90m | 9ft 6in |
| Internal length | Approx. 12.00m to 12.03m | Approx. 39ft 4in |
| Internal width | Approx. 2.33m to 2.35m | Approx. 7ft 8in |
| Internal height | Approx. 2.65m to 2.70m | Approx. 8ft 9in to 8ft 10in |
| Door opening width | Approx. 2.34m | Approx. 7ft 8in |
| Door opening height | Approx. 2.58m to 2.59m | Approx. 8ft 5in |
Some published 40ft high cube specifications give a cubic capacity of around 75 to 76 cubic metres. Tare weight also varies between specifications. If your load is close to the available height, width, door opening or permitted weight, confirm the particular container rather than relying on nominal dimensions.
Standard 40ft or high cube?
The main difference is height. Both have the same nominal 40ft length and 8ft width, but the high cube adds approximately 305mm of external height. This also increases the internal height and usually gives a taller door opening.
A high cube makes sense where height is genuinely limiting the way you store or load goods. Tall pallets, machinery, bulky equipment and vertically stacked stock can make better use of the additional space. The extra volume is less useful where the contents are dense and heavy, because weight limits may be reached before the container is physically full.
Door clearance deserves separate attention. An item may fit inside the container but still be too tall or awkward to pass through the cargo doors. Check both the internal dimensions and the door aperture before ordering machinery or other close-fitting loads.
Buying a 40ft high cube container
Purchase can suit a longer-term requirement where you expect to keep the container in regular use. Ownership also gives more freedom to consider later alterations, although the container structure, proposed modifications, site and planning requirements still need to be assessed.
Ask what condition is being offered. One-trip normally means the container has completed a limited initial shipping journey from its place of manufacture. It does not mean unused, so minor dents, scrapes, tyre marks and handling marks can still be present.
Used high cubes can vary more in age, paint condition, repairs and previous service. Check the roof, side walls, doors, hinges, locking bars, seals and floor. If appearance matters, discuss it separately from structural or weather-related condition descriptions.
Hiring a 40ft high cube container
Hire can work well for temporary storage, a defined project or additional capacity that will not be needed permanently. Before agreeing to hire, confirm the intended period, permitted use, responsibility for damage, collection arrangements and any restrictions on modifications.
Collection access should be planned at the beginning rather than when the hire ends. A 40ft unit needs space for the collection vehicle and lifting arrangement, so avoid allowing later fencing, stored materials, plant or building work to block the route.
If you are unsure which route suits the project, compare the expected period of use with the costs and responsibilities attached to purchase and hire. Include those details when you request a container quote.
Condition terms to understand
Container descriptions refer to different things and should not be treated as interchangeable guarantees. One-trip describes limited initial transport use. Used refers more broadly to previous service and can cover containers in a range of ages and cosmetic conditions.
Wind and watertight generally relates to resistance to ordinary weather ingress when the container is in suitable condition. It does not mean airtight, and it does not tell you the age or appearance of the unit.
Cargo-worthy relates to condition for cargo transport, while IICL refers to industry inspection and repair standards. CSC plating concerns container safety approval for international transport. If you intend to ship the container rather than use it for static storage, confirm current certification, carrier acceptance and any cargo requirements for the actual unit before booking transport.
Using the extra height effectively
The additional headroom becomes useful when the internal layout is planned around it. Taller shelving or racking may allow more goods to be stored without increasing the footprint, provided the installation and loads are suitable for the container and intended use.
For bulk storage, consider how frequently each item needs to be reached. Goods placed at the far end of a 40ft container can become difficult to retrieve if the aisle is filled later. Keep frequently used stock near the doors or maintain an access route where regular retrieval is required.
Forklift loading can also benefit from a taller door opening where the load itself needs the clearance. The site still needs enough working space outside the doors for the handling equipment being used.
Condensation, ventilation and insulation
Extra cubic capacity does not remove the usual moisture considerations of a steel container. Condensation can develop when temperature and humidity change, particularly where stored goods release moisture or the container experiences large changes in temperature.
Ventilation can improve air movement. Lining, insulation and anti-condensation treatments may also be considered where the stored goods justify them, but no single measure suits every use. Paper, furniture, machinery, stock and building materials can require different approaches.
Keep sensitive goods away from areas where moisture could collect and avoid packing the container so tightly that inspection becomes impossible. The information on whether shipping containers are waterproof explains the difference between weather resistance and other moisture risks.
Prepare the Felixstowe site for HIAB placement
A 40ft high cube takes up more space than its final footprint suggests during delivery. HIAB delivery uses a crane mounted on the vehicle, so the vehicle needs a suitable route, a workable position and enough crane reach to place the container.
Measure the narrowest gate and approach. Check turning space, ground conditions and overhead obstructions such as cables, branches, roof edges and other structures. The extra height of a high cube should also be considered along the complete access route.
Tell the supplier where the delivery vehicle can stand and which way you want the cargo doors to face. Crane reach and site conditions can affect what placement is possible, so the final position should not be assumed before the access information has been checked.
The container should sit on firm, reasonably level support appropriate for the expected load. Uneven settlement can twist a long container and make its cargo doors harder to use. Good drainage also helps prevent water collecting around the container and entrance.
The advice on proper shipping container placement covers the main points to consider before delivery.

Planning considerations in Felixstowe
Planning requirements can depend on the intended use, how long the container will stay in place, the status and location of the site, neighbouring property, listed status, conservation areas, any change of use and associated works or modifications.
There is no planning rule that applies to every 40ft high cube container. Check the current requirements with the relevant local council before committing to a permanent position or carrying out conversion work, rather than assuming permission is always required or always unnecessary.
Choose the right 40ft high cube
Start with the load rather than the container label. Check the tallest and widest item, the way it will pass through the doors, the total weight, how often the contents need to be reached and whether the extra height will actually be used.
Then consider whether purchase or hire fits the expected period and whether the Felixstowe site has enough room for placement, day-to-day loading and future collection. You can compare other designs through the container equipment range before you request a container quote.
