30ft shipping containers occupy the middle ground between a 20ft and a 40ft, with around 226 sq ft of floor and 29 ft 4 in of internal length. They are specified when a 40ft cannot be delivered or will not fit the plot, but a 20ft does not provide enough space.

Common applications include conversions that need an extra room, sites with a hard limit on length, and storage requirements that fall awkwardly between the two standard sizes. Because 30ft units are not a standard ISO shipping length, stock is limited and moves quickly. If nothing suitable is listed, tell us what you need and we will confirm availability. Our size guide compares every length side by side.
