Container Sizes: From 20 Feet to 40 Feet [2021 Update]
Understanding container sizes for export purposes is essential if you intend to use them for storage—or even as creative housing.
The wide variety of container types and sizes helps you choose the right one for your needs.
Export containers are known to be multifunctional and applicable to various uses. Much of the transportation infrastructure is designed with this in mind, along with the compatibility of the containers themselves.
These two aspects are likely what have made export containers so popular from the start. Understanding the common container variants builds your foundational knowledge of container types.
20-Foot Container
The 20-foot container is one of the most popular due to its lightweight and ease of maneuverability.
Some people even convert them into small cabins as part of larger buildings.
However, 20-foot containers are often more expensive per square foot than 40-foot ones. For the same total space, you’d need twice as many 20-foot units—so unless your design demands it, 40-foot containers are generally a more efficient choice.
