Tumi publishes a single exterior dimension set per bag plus weight and volume; on its international English catalog these are given in centimeters and kilograms, converted here to inches. The catalog labels the figure only as DIMENSIONS and does not state whether wheels and handles are included, so wheel inclusion is left unasserted; airport gate sizers measure overall size including wheels and handles, so treat these as approximate at the gate.
