A 20-foot containerâs overall capacity is 1,170 cubic feet and its maximum gross weight is 6,700 pounds. These limits vary slightly according to where in the world youâre shipping from, so always check with your agent. 20-foot long container is 8 feet 6 inches tall, and 8 feet wide. This gives you an internal space of 19 feet and 4 inches in length, by 7 feet 8 inches in width and 7 feet and 10 inches in height.
Allowing for the tare mass of the container, the maximum payload mass is therefore reduced to approximately 22,000 kg (49,000 lb) for 20 ft (6.10 m), and 27,000 kg (60,000 lb) for 40 ft (12.19 m) containers.he maximum gross mass for a 20 ft (6.10 m) dry cargo container is 24,000 kg (53,000 lb), and for a 40 ft (12.19 m) container (including the 9 ft 6 in or 2.90 m high cube) it is 30,480 kg (67,200 lb).
