20ft vs 40ft Containers: Which Size Should You Choose?
back
When buying a shipping container, size is one of the most important decisions you will make. Whether you need secure storage for tools, stock, equipment or furniture, the choice between a 20ft container and a 40ft container affects how much you can store, how easily the unit can be sited and how much space is required for delivery. Both sizes are extremely popular, but each one suits different needs, sites and budgets.
What Is the Difference Between 20ft and 40ft Containers?
A 20ft shipping container is the most widely used size because it is compact, practical and suitable for most applications. A 40ft container offers double the length and significantly more storage volume, making it ideal for larger commercial needs. Knowing the physical difference helps you understand how much space you will gain and how much room you need for installation.
Typical external dimensions are:
20ft container: around 6.1m long, 2.44m wide and 2.59m high
40ft container: around 12.2m long, 2.44m wide and 2.59m high
The footprint alone makes the decision very different depending on your site layout and access.
Is a 20ft Container the Right Choice for You?
A 20ft container is often the best option for customers who need reliable storage without taking up too much space. Its smaller footprint makes it easier to position on domestic, commercial and industrial sites. It is also more practical when access is tight or when space for delivery vehicles is limited. Many customers choose a 20ft unit when they want secure storage for tools, equipment, business stock or seasonal items. It also suits small businesses, garages, tradespeople and community groups who want to keep costs manageable while still gaining strong security and weatherproof protection.
When a 40ft Container Is the Better Option
A 40ft container offers a significant increase in usable space and is ideal for businesses with high storage demands. It is commonly used by construction companies, manufacturers, retailers, agricultural businesses and organisations that need larger scale storage for bulky goods or multiple pallet loads. Customers often choose 40ft containers when they want to store large volumes under one roof rather than splitting stock across separate units. It is also a cost effective solution when buying long term, as the price per square foot of storage is typically lower than two individual 20ft containers.
Practical Considerations When Choosing Between 20ft and 40ft
Before deciding on a container size, it is important to consider:
- Available space on site: A 40ft unit needs a larger, clear and level area
- Access for delivery vehicles: Delivery vehicles require turning room and straight access
- Future storage needs: Choosing a larger unit now may prevent the need for a second unit later
- Budget: A 20ft container is usually the more cost effective choice for smaller needs
- Weight and positioning: Larger containers require more planning for unloading and placement
Delivery access is one of the biggest factors. A 40ft container requires a longer vehicle, more manoeuvring room and a straight approach for safe unloading. If your site has sharp turns, narrow entrances or restricted access, a 20ft container may be the practical choice.
Cost Differences Between 20ft and 40ft Containers
While prices vary depending on condition and specification, a 20ft container is generally cheaper to purchase. A 40ft container provides more storage for the price, making it better value for large scale requirements. Buyers with limited budgets, smaller sites or modest storage needs often choose a 20ft container, while businesses with long term or heavy duty demands benefit from the capacity of a 40ft unit. Both provide durable, secure and weatherproof storage.
