Storage containers are available in a wide range of sizes. The most common options are 8’ wide, 8’6” high, and 20 or 40 feet long, giving a total volume of 1,170 cubic feet or 3,340 cubic feet. Businesses typically choose 20’ containers as they offer easier access to any items kept to the back of the container. A 40’ model offers around three times as much space, but they could require extra doors at the back to properly take advantage of the larger space. A “high cube” container, for the record, has an internal height of 9’6”. Some sellers will offer different length containers, including lengths as small as 6’ and as large as 54’, but it can be hard to find a specialty size like this, and you should understand the purposes of these specially-sized storage containers. These containers are only for domestic use and they cannot be shipped overseas. Storage containers are stackable too, which is another reason they save so much space. It’s possible to hoist a 20’ unit with a forklift so that it can be placed on top of another unit.
