These are planning references used by CargoToolsHub calculators, not a substitute for the actual equipment specification or CSC plate. Dimensions and payload vary by manufacturer, operator and unit.
Use the right capacity check
Container CBM compares shipment cube with nominal volume. Container Payload compares both cube and weight. Container Door Fit addresses the different question of whether a rectangular item can pass through the doorway.
