20ft Shipping Container Dimensions
The 20ft shipping container serves as the primary benchmark for the global transport industry and remains the most versatile unit for local storage. At Shipping Containers of Southampton, we supply high-specification 20ft units to businesses and residents throughout Hampshire. Each unit we provide is wind and watertight, meaning the container is fully sealed against the elements to keep your goods dry and protected. Whether you intend to buy shipping containers for permanent site use or seek 20ft container hire options for Southampton businesses, understanding the precise physical footprint is vital for a successful delivery.
All our units meet strict ISO standards and come with a valid CSC plate. A CSC plate is a safety certificate used for international shipping that proves the container is structurally sound and safe for stacking or sea freight. For those requiring the highest quality, we stock "one-trip" units. A one-trip container is a unit manufactured abroad that carries a single cargo load to the UK, ensuring it arrives in near-pristine condition. For more details on these premium units, see our guide to single-trip shipping containers.

Accurate measurements prevent costly errors during site placement or cargo loading. The following table provides the standardised data for a standard 20ft "Dry Van" container. We recommend checking standard shipping container dimensions before finalising your site foundation plans.

| External Length | 6.06 m | 19' 10.5" |
| External Width | 2.44 m | 8' 0" |
| External Height | 2.59 m | 8' 6" |
| Internal Length | 5.90 m | 19' 4" |
| Internal Width | 2.35 m | 7' 8" |
| Internal Height | 2.39 m | 7' 10" |
| Door Opening Width | 2.34 m | 7' 8" |
| Door Opening Height | 2.28 m | 7' 5" |

In the logistics sector, a 20ft unit is often referred to as a twenty-foot equivalent unit (TEU). This term helps port authorities and shipping lines calculate a vessel's or a terminal's capacity. When loading the unit, you must account for the door aperture, as the internal width and height are slightly larger than the opening itself. For more specific measurements, view our 20ft shipping container dimensions page.
Weight, Payload, and Pallet Capacity
Understanding weight limits is critical for safe transport and to avoid road legal infractions. Three key terms define the weight of a container: Tare, Payload, and Gross weight. Tare is the weight of the empty container. Payload is the maximum weight of the cargo that can be loaded inside the unit. Gross weight is the sum of the tare and the payload.
- Tare Weight: Approximately 2,300 kg.
- Maximum Payload: Approximately 28,200 kg.
- Maximum Gross Weight: Approximately 30,480 kg.
A standard 20ft container can accommodate 10 standard UK pallets or 11 Euro pallets in a single tier. For high-density storage requirements, many clients in Southampton use stacking strategies. However, you must verify the floor strength and ensure your cargo remains within the payload limits. For more information on weight compliance, read our container weight verification guide.
Logistics and Delivery Intelligence in Hampshire
Navigating the logistics of a 20ft unit requires specialised equipment. Shipping Containers of Southampton utilises HIAB crane-mounted lorries for all regional deliveries. A HIAB is a truck fitted with a hydraulic crane that allows our operators to lift and place the container with precision, even over low walls or fences. This eliminates the need for an on-site forklift or a separate crane.
To ensure a safe and successful delivery, your site must meet specific ground requirements. We recommend a level, hard-standing surface such as concrete, tarmac, or compacted gravel. Delivering on soft grass or sand is unstable and can cause the heavy delivery vehicle to sink. For detailed site preparation advice, view our guide on preparing your site foundation.
Key delivery clearance requirements include a minimum height clearance of 15ft and ensuring that no overhead power lines are within 20 metres of the vehicle. If you have concerns about site access, you can request a delivery assessment from our team.
Ground Requirements and Site Foundations
A stable, level foundation is the most important factor for the long-term performance of your container. If a unit is placed on uneven ground, the frame can twist slightly. This problem, known as racking, can cause heavy steel doors to jam or become impossible to lock. Shipping Containers of Southampton recommends several foundation types for your container footprint measurements, including railway sleepers or concrete pads.
For clients seeking professional-grade used units, we uphold high repair standards to ensure superior structural integrity. Check out our container refurbishment and repair guide for tips on protecting your investment and keeping your containers cargo-worthy.
Planning and Local Authority Compliance
Shipping containers are generally considered temporary structures in the UK. However, placement in certain areas of Hampshire may require specific notice or permission, especially if the unit stays on site for more than 28 days or is located in a Conservation Area. We recommend all clients check our dedicated guide on local council planning rules for containers.
You can access local guidance via these portals:
How much space is needed for a 20ft container delivery in Southampton?
The delivery vehicle is roughly 40ft long. You need approximately 60ft of linear space to allow the truck to pull away once the container is placed. We also need to assess overhead clearance for the HIAB crane. To ensure your site is suitable, speak to our Southampton experts for a quote.
What is a high cube 20ft container?
A standard 20ft unit is 8ft 6in tall. A high-cube unit is 9ft 6in tall, providing an extra foot of vertical space. This is useful for storing tall machinery or for improving airflow in refrigerated units. You can view the full ISO container dimension guide for more details.
Can I fit a car inside a 20ft container?
Yes, most standard cars fit inside a 20ft container. The internal width is 2.35m, which accommodates most vehicles. However, you must ensure the car is properly secured. For oversized vehicles, you may prefer specialist flat-rack containers, which lack side walls.
Are the 20ft containers still weatherproof?
Absolutely. At Shipping Containers of Southampton, every used unit we sell is guaranteed wind and watertight. We inspect the door seals and the roof for any signs of leaks before dispatch. For more on how we maintain our stock, see our article on buying cargo-worthy containers.
