Large suitcases are where luggage quietly goes wrong: a 28 inch case can weigh five kilograms empty, then pass 23 kg with a fortnight of clothes inside. The buying decision is mostly about weight discipline and wheel quality, not looks.
Capacity: think in litres and kilos
- Medium (24–26 inch, ~65–75 L) — one to two weeks for one person. The most useful checked size.
- Large (28–30 inch, ~95–110 L) — family trips, winter clothing, or moving house.
- Extra-large (32 inch+) — rarely worth it: you will exceed airline weight limits before you fill it.
Every kilo the case weighs is a kilo you cannot pack, and excess-baggage fees are usually higher than the price difference between a cheap and a good case.
Shell materials
Polycarbonate flexes and returns to shape — the best protection-to-weight ratio. ABS is cheaper, heavier and cracks rather than flexes in cold. Aluminium looks superb, dents, and costs the most. Fabric cases with a rigid frame split the difference and often include outer pockets.
Wheels, handles, expansion
- Four spinners roll beside you with almost no wrist load, but protrude and break first on kerbs.
- Two inline wheels survive rough ground better and cost you less packing volume.
- Telescopic handles should extend without wobble; a rattling handle is a failed trip waiting to happen.
- Expansion zips add real litres on a medium case and are close to useless on a large one.
Weight and lock strategy
Weigh the packed case at home with a hanging scale. Aim for 21–22 kg, leaving room for a souvenir or a wet towel. A TSA-accepted lock helps in the US and Canada; elsewhere any combination lock works.
Matching the case to the trip
- One person, one week — 24 inch (65 L) is the sweet spot; a 28 inch case invites overpacking.
- Two people, two weeks — two 24 inch cases beat one 28 inch: easier to lift, easier to split if a bag goes missing.
- Family of four, one week — 28 inch + 24 inch checked, plus two cabin bags, usually fits a 4 × 23 kg allowance.
- Winter or ski trip — one 28 inch for clothing plus a separate boot or gear bag; do not compress boots into a case full of clothes.
Common mistakes
Buying a 28 inch case for a 20 kg allowance, then filling it and paying excess fees. Ignoring handle wobble because the shell looks premium — handles fail first. Trusting "scratch-resistant" or "unbreakable" marketing instead of checking whether wheels are replaceable. And packing to the case's capacity rather than to the airline's weight limit, which is the limit that actually costs money.
