Understanding the Importance of Choosing the Right Container Size
When hiring a shipping container, selecting the correct size is one of the most important decisions. The wrong size can result in wasted space, added transport costs, or difficulty storing essential items. Whether you need a unit for business stock, tools, furniture, or site equipment, the dimensions must match your purpose.
At Unit Group, we offer a wide range of sizes to suit short-term projects, long-term hire, or temporary storage. By understanding how each container size differs, you can make a well-informed choice.
Here’s what you should consider:
- Volume of goods or equipment to be stored
- Site space limitations
- Duration of hire
- Delivery access for larger containers
Overview of Available Shipping Container Sizes
Unit Group provides shipping containers in a variety of sizes, from compact 6ft units to large 45ft containers. Each size is suited to different applications across domestic, construction, retail, logistics, and industrial sectors.
The most commonly hired container sizes include:
- 6ft and 8ft containers: best for limited space and small storage jobs
- 10ft and 20ft containers: widely used for general business and site storage
- 30ft, 40ft and 45ft containers: suited to bulk storage or commercial transport
Below is a breakdown of each container type to help you decide which option is right for your project.
6ft Shipping Containers
Ideal for Limited Spaces and Small Storage Needs
6ft shipping containers are the most compact size available and are ideal for tight locations or small-scale storage requirements. They are popular with domestic customers, tradespeople, and businesses that need secure storage on smaller sites.
Common uses for 6ft containers include:
- Storing tools and equipment
- Archiving files or small inventories
- Temporary household overflow storage
- Secure container hire in tight access areas
Despite their small size, these containers are built with the same high-quality steel construction as larger units, offering durability and weather resistance.
8ft Shipping Containers
8ft containers strike a balance between compact design and usable storage space. They are often used in residential settings or on job sites where space is at a premium. With easy ground-level access, they make storing and retrieving items simple.
Benefits of 8ft container hire:
- Great for garden tools or seasonal equipment
- Can be used on driveways or small plots
- Easier and cheaper to transport
- Suitable for short-term or long-term hire
These containers are fully wind and watertight, and like all our hire units, they are delivered clean and ready to use.
10ft Shipping Containers
10ft shipping containers offer an excellent solution for customers who need more space than 6ft or 8ft units but don’t require the footprint of a 20ft container. They are suitable for commercial use, home storage, or as temporary site accommodation.
Common applications include:
- Secure storage for retail stock
- Tool and material storage for trades
- Use as site offices with modification
- Flexible option for growing storage needs
With a smaller footprint, they fit easily into most locations while offering ample internal capacity. Unit Group offers these units with short and long-term hire options.
20ft Shipping Containers
20ft shipping containers are one of the most widely used sizes across various sectors. These units provide a strong combination of size, durability, and accessibility. They’re ideal for long-term storage, equipment hire, or transport needs.
Benefits of hiring a 20ft container:
- Fits standard lorry and forklift access
- Internal capacity suitable for business storage
- Can be used for portable workshops
- Fully lockable and weatherproof
Whether you need it for construction, warehousing or event logistics, this size is a safe choice for most scenarios.
30ft Shipping Containers
30ft containers are a step up from the 20ft option, giving you extra storage space without jumping to the length of a 40ft unit. These are ideal when you need more capacity but still want manageable transport and placement.
When to choose a 30ft container:
- Extra buffer space for seasonal stock or equipment
- Store bulky items that won’t fit in a 20ft
- Ideal for workshops, storage depots or mobile stores
- Can be used as modified welfare units
Available for short or long-term hire, Unit Group can deliver these to most commercial or industrial sites.
40ft Shipping Containers
A 40ft container is one of the largest standard-size shipping units available for hire. It is the go-to option for businesses dealing with bulk goods or requiring a high volume of storage. Despite its size, it is still transportable by standard lorry.
Key features include:
- Double the capacity of a 20ft unit
- Strong security features for high-value goods
- Can be used for temporary warehousing
- Ideal for export, site logistics or renovation projects
These containers are available with various door options and modifications if required.
45ft Shipping Containers
For those who require even more storage than a 40ft container, the 45ft unit provides the most internal space. These units are designed for commercial use and are especially useful for warehousing, transport logistics or high-volume equipment storage.
Who should hire a 45ft container:
- Businesses managing extensive stock levels
- Sites with high storage turnover
- Large-scale construction or industrial needs
- Temporary warehousing with secure access
Unit Group offers flexible delivery options and competitive hire rates for 45ft containers.
Which Shipping Container Size Do You Really Need?
Choosing the right container size depends on your project requirements, access space, and what you plan to store. Larger isn’t always better if you’re limited by space or only storing a few items. On the other hand, underestimating your storage needs could lead to hiring multiple units unnecessarily.
Use this checklist to help guide your decision:
- Measure your available space before ordering
- Estimate how much material or equipment you need to store
- Consider if you’ll need walk-in access or shelving
- Decide if short or long-term hire better suits your budget
Still unsure? The Unit Group team can advise you based on your specific site layout and storage goals.
