The related unit forty - foot equivalent unit, however, is defined as two TEU . The most common dimensions for a 20 - foot (6.1 m) container are 20 feet (6.1 m) long, 8 feet (2.44 m) wide, and 8 feet 6 inches (2.59 m) high, for a volume of 1,360 cubic feet (39 m). However, both 9 - foot - 6 - inch - tall (2.90 m) High cube and 4 - foot - 3 - inch (1.30 m) half height containers are also reckoned as 1 TEU . This gives a volume range of 680 to 1,520 cubic feet (19 to 43 m) for one TEU . </P> <P> While the TEU is not itself a measure of mass, some conclusions can be drawn about the maximum mass that a TEU can represent . The maximum gross mass for a 20 - foot (6.1 m) dry cargo container is 24,000 kilograms (53,000 lb). Subtracting the tare mass of the container itself, the maximum amount of cargo per TEU is reduced to approximately 21,600 kilograms (47,600 lb). </P>
