Standard containers are also known as general purpose containers. They are closed containers, i.e. they are closed on all sides.

The various types of standard container also differ in dimensions and weight, resulting in a wide range of standard containers.Standard containers are mainly used as 20′ and 40′ containers. Containers with smaller dimensions are very seldom used. Indeed, the trend is towards even longer dimensions, e.g. 45′.
