Shipping containers come in a handful of standard sizes: 10ft, 20ft, 40ft and 45ft, plus small 8ft units. All of them are 8 feet wide, and most come in standard or high cube height. This guide helps you choose the right size for storage, a workshop, an office or a home.
Andy compares the common container sizes and what each one realistically holds.

How to choose the right size
Start with what you need to store or build
Measure the largest items, count pallets or furniture, and leave room for an aisle if you need to reach everything. As a rule of thumb, a 20ft container holds the contents of a one or two bedroom home and a 40ft the contents of a three or four bedroom home. A car fits in a 20ft, but with little room to open the doors. For palletized goods, see how many pallets fit in a shipping container.
Check your site and delivery access
The container has to reach your site and fit on it. A tilt bed delivery needs about 60 feet of straight clearance for a 20ft and about 100 feet for a 40ft, plus room in front for the doors to swing open. On tight lots, a 10ft or 20ft is often the only size that works. Our guide to shipping container delivery explains what the truck needs.
Bigger is usually better value
A 40ft container gives twice the floor space of a 20ft but does not cost twice as much. At US depots today, a used cargo worthy 20ft starts at about $1,045 and a used cargo worthy 40ft at about $1,395. Delivery for a 40ft costs a little more, but per square foot the 40ft almost always wins if you have the space. Current figures for every size are on our shipping container prices page.
Standard or high cube
A high cube is one foot taller, 9ft 6in instead of 8ft 6in outside, which adds about 13 percent more volume. Choose a high cube for anything people will stand, live or work in, and for tall goods. For plain storage, a standard container is enough and costs a little less. Our guide to standard vs high cube containers compares both in detail.
One large container or two small ones
Two 20ft containers cost more than one 40ft, but they can be placed separately, fit through tighter access and give you two sets of doors. If you choose a 40ft and want to reach the back easily, ask for a double door container with doors at both ends.

Less common sizes
8ft containers are the smallest common size and suit narrow side yards and small business premises. 10ft containers are mostly built new for storage or cut down from 20ft units, because they are rarely used in shipping.
45ft high cubes are the longest ISO containers and come up for sale in some port cities. 53ft domestic containers are 8ft 6in wide and are used by US rail and trucking companies. They occasionally become available for storage, but need even more delivery space.

In global shipping, 40ft high cubes and 20ft standard containers are the most common. For buyers in the US, 20ft and 40ft containers are the easiest to find and the best value.
02
All standard ISO shipping containers are 8 feet wide outside, from 10ft to 45ft. Only the 53ft domestic containers used on US rail and trucks are wider, at 8ft 6in.
03
A 20ft container fits one car, though there is little room to open the doors inside. A 40ft fits two cars, or one car plus storage.
04
No. In the same grade, a 40ft usually costs only somewhat more than a 20ft, which makes it the better value per square foot if your site has room for it.
05
Yes. 8ft and 6ft containers are built for storage, mostly new. They cost more per square foot but fit where a larger container cannot be delivered.
