A 40ft Flat Rack measures 11.66 m (38′3″) long, 2.24 m (7′4″) wide and 2.00 m (6′7″) high inside — about 52.2 m³ (1,843 ft³) of usable space, with a payload up to 39,000 kg (85,980 lb).
ISO 40ft flat rack for heavy machinery, pipe bundles, and oversize cargo. Height is the nominal loadable height.

Internal (usable) figures, not external. Capacity is the geometric interior volume — real cargo never fills 100% of it, because pallets, dunnage and irregular shapes leave void space.
The table above is the box. What matters is how your cargo sits in it — how many units fit, where the weight lands, and whether you run out of floor or payload first. Enter your cargo and get the answer, free and without signing up.
