QUICK CHOOSER
55 cm is usually the cabin starting point. Choose 65 cm for a versatile checked bag and 75 cm only when trip length, climate or shared packing genuinely needs the volume.

Three questions that decide the size
- Will it enter the cabin?A “55 cm” label is not enough. Check all external dimensions against every airline in the itinerary.
- Who has to move it?Train platforms, stairs, small taxis and uneven pavements can make spare capacity feel expensive.
- What limits you first?On dense loads, airline weight usually becomes the constraint before the suitcase is physically full.
One large bag or two medium bags?
Two medium bags distribute weight and are easier for two adults to manoeuvre, but create more pieces to track. One large bag simplifies counting while concentrating handling risk and making it easier to cross a per-bag weight limit.
