Dimensions / Industrial & logistics / Shipping containers / 40 ft
A 40 ft dry container is 12,192 × 2,438 × 2,591 mm outside (ISO 668), the same width and height as a 20 ft, and usually 12,032 × 2,352 × 2,393 mm inside with a 2,340 × 2,280 mm door and 67.7 m³ (Triton, Seaco, SeaCube). It takes twice the volume of a 20 ft but not twice the weight: Triton’s 40 ft carries 28,960 kg against 28,380 kg for its 20 ft, and ONE lists 26,840 kg. One layer holds about 23–25 Euro pallets or 20 North American ones.

This starts from Triton’s 40 ft. Change it to the box on your booking, then enter your pallets and how high you will stack them.
Sizes in millimetres, weights in kilograms. 1 in = 25.4 mm, 1 lb = 0.454 kg.
Its 1016 mm side goes through the 2340 mm door with 1324 mm to spare, and its 1600 mm height clears the 2280 mm opening by 680 mm.
A 40 ft has the same door as a 20 ft: 2,340 × 2,280 mm at Triton and Seaco.
One layer takes 20 pallets of 1219 × 1016 mm in straight rows; 1 high that is 20, enough for your 20.
Triton says up to 25 Euro pallets per layer, Seaco about 23: leave room to handle them.
20 pallets × 1000 kg = 20000 kg, 8960 kg under the 28960 kg maximum payload.
Double the floor is not double the weight: Triton’s 40 ft carries 28,960 kg, its 20 ft 28,380 kg.

Usually 12,032 × 2,352 × 2,393 mm, with a 2,340 × 2,280 mm door and 67.7 m³ (Triton, Seaco, SeaCube, DFIC). Textainer lists 12,025 × 2,348 × 2,385 mm and Evergreen 2.385 m high, so allow a few millimetres.
In volume, about: 67.7 m³ against 33.2 m³ (Triton). In weight, no: the payload is about the same, 28,960 kg against 28,380 kg at Triton, and some carriers list less for the 40 ft (ONE 26,840 kg).
In one layer, about 23 Euro pallets (Seaco) or up to 25 (Triton), or 20 North American pallets of 1.016 × 1.219 m (Seaco).
A tunnel in the underside that lets the box ride on a gooseneck chassis. Hapag-Lloyd fits one to all its 40 ft containers.
Only when it is empty: on containers of 30 ft and longer, fork-lift pockets, where fitted, are for lifting empty containers (IMO).
Evergreen gives 67,200 lbs maximum gross on US rail, chassis included, against 52,900 lbs for a 20 ft.
Buyers filling a 40 ft weigh it against a high cube: how many of your cartons or pallets go in each, the carton size and gross weight, and how tall a loaded pallet stands. Show those sizes on your own product photo in SizeMarker, as at the top of this page, and share one product card in the chat.
