Which shipping container size do I need?
Choosing the right shipping container size depends on how much space you need, how your site can be accessed, and what you plan to store. In the UK, the most common options are 10ft, 20ft, and 40ft shipping containers, each offering different capacities, delivery requirements, and costs. This guide explains the key differences so you can choose the right container first time.
10ft Shipping Containers: Dimensions, Uses & Benefits
10ft shipping containers are bespoke cut-down units, created from standard 20ft or 40ft containers. Because they are not ISO-certified, they cannot be shipped internationally or lifted while loaded. Instead, they are designed specifically for secure, wind and watertight on-site storage.
These containers are extremely popular where space is limited and a full-size unit would not be practical.
Best suited for:
- Construction sites with restricted access
- Small businesses needing compact secure storage
- Domestic storage for tools, equipment, or furniture
- Locations requiring delivery via a rigid HIAB vehicle
If you require greater internal space or ISO-certified lifting capability, a 20ft or 40ft shipping container may be more suitable.

20ft Shipping Containers: Dimensions, Uses & Benefits
20ft shipping containers are the most popular container size in the UK. These ISO-certified units retain all four original corner castings, allowing them to be lifted, stacked, and transported while loaded.
Available as used containers or new “one-trip” units, 20ft containers offer an excellent balance of capacity, affordability, and delivery flexibility. A 20ft high cube container is also available, providing an extra foot of internal height for taller or bulkier items.
Why businesses choose 20ft containers:
- ISO-certified and fully transportable
- Versatile internal space for a wide range of uses
- Easy delivery using a rigid HIAB vehicle
- Ideal for secure storage, workshops, and container conversions

40ft Shipping Containers: Dimensions, Uses & Benefits
40ft shipping containers provide the largest internal volume and are one of the most cost-effective solutions for businesses that need to store or manage large quantities of goods. The 40ft high cube container is especially popular thanks to its additional internal height.
For UK domestic use, 40ft containers are commonly used for secure, wind and watertight storage, warehousing overflow, and larger operational or industrial setups.
Important delivery note:
40ft containers require arctic HIABs, side loaders, or skeletal trailers. These vehicles are approximately 68ft long, so suitable site access and turning space must be confirmed before delivery.

1. Site Access
Always consider how the container will be delivered.
- 40ft containers require arctic vehicles and significant turning space
- 20ft and 10ft containers can usually be delivered using rigid HIAB vehicles

2. What You Need to Store
The type, size, and volume of items you plan to store will determine the best container size.
- Larger or bulkier items may require a 20ft or 40ft container
- Tools, equipment, or household items are often well suited to a 10ft container
Review the shipping container dimensions UK tables above to ensure the internal space meets your requirements.
3. Budget
Pricing varies by size and specification.
- 20ft and 40ft containers benefit from global production volumes, making them more cost-effective
- 10ft shipping containers on most occasions are bespoke units and typically cost more per square metre.
