Know the usable capacity of standard containers so you can plan loads and compare FCL vs LCL accurately.

Standard dry containers

  • 20ft (20GP): ~28 CBM usable, ~21,800 kg max payload.
  • 40ft (40GP): ~58 CBM usable.
  • 40ft High Cube (40HC): ~68 CBM usable — most common for light freight.

Special containers

  • Reefer: temperature-controlled.
  • Open-top: top-loaded cargo.
  • Flat-rack: oversized/wide pieces.

Planning tip

Do not pack to the theoretical max — leave working space and respect payload limits. We help you choose the right box for your cargo.
