What is the biggest difference in practice?

In practice, the choice between 20ft and 40ft is usually decided based on space, volume, and logistics. The cheapest or largest option is not automatically the best choice.

Space on location

Placement space and accessibility

A 20ft container fits in many more locations than a 40ft container. Those with limited space, a narrower entrance, or less room to maneuver usually opt for a 20ft container more quickly.

What does this mean?

Therefore, don't just look at the content, but first at the space on the site and the delivery route.

Storage volume

More content or more flexibility

A 40ft container offers approximately twice the capacity of a 20ft container. This makes 40ft attractive when maximum storage capacity is important.

What does this mean?

If you don't really need that extra volume, a 20ft container is often the more efficient choice in terms of purchase, placement, and use.

Transport

Delivery and installation costs vary accordingly

A 40ft container usually places higher demands on transport and placement than a 20ft container. The location must be spacious enough for delivery and safe unloading.

What does this mean?

For hard-to-reach locations or limited placement space, 20ft is often quicker and easier to arrange.

Use Case

When do you choose which size?

20ft is the all-round size for storage, construction, and transport. 40ft is particularly attractive when a large volume is needed for logistics, bulk storage, or larger inventory flows.

What does this mean?

So choose based on usage: all-round and practical with 20ft, or maximum volume with 40ft.

In short

Choose 20ft if you are looking for an all-round container that is practical to place in many locations. Choose 40ft if maximum storage capacity is more important than compact placement.

Choose quickly in 3 steps

1. Consider the space: if you have limited placement space, 20ft is usually more logical.

2. Consider the volume: if you really need a lot of storage capacity, 40ft becomes more interesting.

3. Consider delivery: for hard-to-reach locations or when flexible placement is important, 20ft is often easier to organize than 40ft.

When do you choose 20ft instead of 40ft?

A 20ft container is usually the best choice if you are looking for an all-round size that can be easily placed in many locations. Even if you don't need an extremely large volume, 20ft is often the most practical size.

When do you choose 40ft instead of 20ft?

A 40ft container is an interesting option when maximum storage capacity or loading volume is important. This size is often chosen for logistics, larger inventory flows, and situations where the extra length is not an issue.

Is 40ft cheaper per cubic meter of storage space?

This can be the case in some situations, because 40ft gives you much more volume. At the same time, 40ft also requires more placement space and delivery can be more cumbersome. Therefore, always look at the overall situation, not just the volume.

Do transport costs differ between 20ft and 40ft?

Yes, usually. A 40ft container places different demands on delivery and placement than a 20ft container. Therefore, it is wise to always consider transport when choosing between the two sizes.

What if space on location is limited?

In case of limited space, you will usually find a 20ft container to be a quicker solution. Not only must the container itself fit, but the delivery route, maneuvering space, and on-site placement must also be feasible.
