Choosing the right size storage container can feel a bit awkward if you have never bought one before. Too small and you quickly run out of space. Too large and you may spend more than you need or struggle to fit it on site.
The good news is that most storage requirements fall into a few common sizes. For many customers, the decision comes down to 10ft, 20ft or 40ft.
Start with what you need to store
Before choosing a size, make a simple list of what will go inside the container. Tools, machinery, stock, furniture, event kit, building materials and farm equipment all take up space differently.
A container may look large when it is empty, but bulky items can fill it quickly. It is worth thinking not only about what you need to store today, but what may be added over the next few months. Many customers buy for the immediate problem and then wish they had allowed a little more room.
10ft containers: compact and useful
A 10ft container is a good option when space is limited. It is commonly used by smaller businesses, schools, homeowners, tradespeople and sites where a full 20ft unit would be too large.
A 10ft container is useful for tools, small machinery, maintenance equipment, sports kit, archived materials, spare parts and seasonal items. It gives secure storage without taking over the whole yard.
The main thing to remember is that 10ft containers are compact. They are very useful, but they can fill up faster than expected if you need to store pallets, long materials or large equipment.
20ft containers: the most popular storage size
For many customers, a 20ft storage container is the best all-round choice. It offers a useful amount of storage space while still being manageable for delivery, siting and everyday access.
A 20ft container is popular with builders, farms, retailers, schools, councils, mechanics, landscapers and events businesses. It is big enough for tools, stock, materials and equipment, but not so large that it becomes difficult to place on most suitable sites.
If you are unsure and have the space, a 20ft container is often the safest starting point.
40ft containers: maximum storage space
A 40ft container gives a lot of storage capacity. It can work well for large volumes of stock, longer items, bulky equipment, self-storage sites, agricultural storage and businesses that need to consolidate goods in one place.
The main consideration is space. A 40ft container needs a suitable area for delivery, positioning and door access. You also need to think about how you will organise the inside. Without racking or a simple layout, items at the back can become difficult to reach.
For customers with enough room and a clear plan, a 40ft container can offer excellent value per square foot.
High cube containers
High cube containers are usually one foot taller externally than standard units. That extra height can be useful for bulky goods, equipment, racking or anything where headroom matters.
They are worth considering if you need more internal space but cannot add another container. They can also be useful for conversions or workshop-style uses.
Think about access, not just size
The container has to fit your site, but the delivery vehicle also needs safe access. Gates, overhead cables, trees, tight bends, soft ground and narrow lanes can all affect delivery.
You should also leave room for the doors to open fully and for people to move goods in and out safely. A container that fits tightly into a corner may not be practical if you cannot access it properly.
