Choosing a suitcase without a costly mistake: consider size, weight and how you’ll use it

Choosing a new suitcase seems simple, until you reach the gate with one that’s just too large. Or the wheels get stuck, the zip comes under strain or the interior turns out to be smaller than you expected. Marketing terms such as “lightweight”, “extra strong” and “suitable for all airlines” don’t tell you much on their own.

The most common pitfalls are:

  • Confusing external dimensions with interior space: external measurements include the wheels, handles and shell, so the usable capacity may be smaller.
  • Focusing only on the material: a hard-shell suitcase can offer protection, but it isn’t automatically practical or lightweight. A soft-sided suitcase often has a front pocket and is more flexible, but offers less protection from pressure.
  • Treating airline suitability as a guarantee: airlines have different hand luggage limits. Always check the latest rules of the airline you’re flying with.

Which specifications should you check?

1. Size, capacity and weight

For a short business trip or weekend break, a cabin suitcase or carry-on suitcase is usually a better fit than a large suitcase. Don’t just look at the capacity in litres; check the maximum external dimensions too.

A few practical guidelines:

  • Cabin suitcase: often around 30 to 40 litres, suitable for a few days.
  • Medium suitcase: around 55 to 65 litres, handy for a trip of four to six days.
  • Large suitcase: around 90 to 103 litres, designed for longer holidays or a family holiday.

A lower empty weight leaves more room within your luggage weight allowance. However, check that a very lightweight model has enough structure for the way you travel.

2. Hard or soft material

A hard-shell suitcase made from ABS, polycarbonate or a combination of the two holds its shape better and can protect your clothes from pressure from other luggage. A soft-sided suitcase made from, for example, 600D polyester is often lighter and has handy external pockets for documents, a phone or a boarding pass.

Check the product description:

  • ABS+PC: a combination used in various models to create a sturdy exterior without adding too much weight.
  • PC: often used for hard-shell suitcases with a flexible, impact-resistant case.
  • 600D polyester: a woven fabric that gives soft-sided suitcases structure and wear resistance.
  • Aluminium frame: can add extra strength around the closure, but usually increases the empty weight.

Durability claims come from the manufacturer’s product information. Treat them as product specifications, not as a guarantee that a suitcase will remain undamaged in every situation.

3. Wheels, closure and compartments

A suitcase with spinner wheels usually has four wheels that can turn 360 degrees. This is handy on smooth floors in stations and airports. Two wheels can make a suitcase more compact and easy to pull behind you, but require more effort when moving it sideways.

A suitcase with a TSA lock can be opened by authorised security staff using a special key, without forcing the lock. The lock doesn’t prevent every risk of loss or damage. Also look for a sturdy zip or a frame with closure clips.

Check the interior too. Cross straps, a mesh divider and separate compartments make it easier to organise your luggage. For clothes, bedding or camping gear, separate storage bags with zips are useful because you can sort the contents before putting them in your suitcase.

Frequently asked questions about suitcases

What size suitcase do I need for a flight?

For a short flight, a cabin suitcase of around 30 to 40 litres is often practical. A medium suitcase is usually a better fit for four to six days. A large suitcase of around 90 litres or more is suitable for longer trips, but always check your airline’s permitted weight and dimensions.

Is a hard or soft suitcase more practical?

A hard-shell suitcase holds its shape and has a fully enclosed exterior. A soft-sided suitcase is often lighter and more flexible, and usually has a front pocket. Choose a hard-shell model when protection is important, and a soft-sided one when easy access and low weight are your priorities.

How long does a suitcase last?

Its lifespan depends on how you use it, how much you pack, the surfaces you travel over and how well you maintain it. The wheels, zips, handles and closures usually take the most strain. Avoid overfilling the compartments, don’t pull a spinner suitcase over rough paving for long periods, and store it somewhere dry and out of direct sunlight.
