The two most popular shipping container sizes are the 20ft and the 40ft. Both are built to the same tough ISO standards, but they suit very different jobs. Here is how to choose the right one for your storage, business or building project.

Size and capacity at a glance

• 20ft standard: roughly 20ft long x 8ft wide x 8ft 6in high, giving around 1,170 cubic feet of space. That is enough for the contents of a typical one- to two-bedroom home, a small business stockroom or a jobsite tool store.
• 40ft standard: roughly 40ft long x 8ft wide x 8ft 6in high, with about 2,390 cubic feet of space — more than double the room of a 20ft for not much more money.
• 40ft high cube: the same length as a standard 40ft but a foot taller (9ft 6in), ideal for tall equipment, shelving or conversions where headroom matters.

When a 20ft container makes sense

A 20ft unit is the go-to choice when space on your property is tight. It fits on most driveways, yards and smaller commercial lots, and it is easier for a delivery truck to place. It is perfect for home storage, farm equipment, seasonal inventory and secure jobsite storage.

When to step up to a 40ft container

If you need to store vehicles, large machinery, pallets of stock or you are planning a container office, workshop or home, the 40ft is usually the better value per square foot. You get double the floor space with only one set of doors to secure.

Don’t forget delivery access

Before you order, measure the drop-off spot. As a rule of thumb, a 20ft container needs about 60ft of straight clearance for the truck to unload, and a 40ft container needs about 100ft. The ground should be firm and level, with no low wires or branches overhead.
