Updated September 28, 2026Figures calculated with our 3D loading engine

Short answer

A 20ft container measures about 5.90 m long, 2.35 m wide and 2.39 m high inside (19′ 4.5″ × 7′ 8.5″ × 7′ 10″). That is 33.1 m³ (1,170 ft³). It carries up to about 28,200 kg (62,170 lb) of cargo. The door opening is about 2.34 m wide and 2.28 m high.

What fits in a 20ft container

  • Euro pallets (120 × 80 cm), one layer: 11
  • US pallets (48 × 40 in), one layer: 9
  • Cartons 60 × 40 × 40 cm: about 262
  • Cartons 50 × 40 × 30 cm: about 472
  • Usable carton volume: roughly 25–28 m³

When to use a 20ft container

The 20ft is the workhorse for heavy cargo. It carries almost the same payload as a 40ft in half the space, so dense goods such as tiles, steel, paper, stone, bagged minerals and machinery fill it efficiently. It is also the usual choice for shipments of roughly 15–28 m³ that are too big for LCL.

Its break-even density is about 851 kg per m³: cargo heavier than that per m³ reaches the weight limit before the container is full.
