Choosing a suitcase without making a costly mistake: consider size, wheels and material

A suitcase may seem simple to choose, until you find yourself at the airport with one that is just too large for hand luggage, a wobbly pull handle or not enough room for your belongings. Marketing terms such as “lightweight”, “extra strong” and “quiet” do not always tell the whole story either.

With this practical buying guide, you can compare a travel suitcase based on measurable features. This makes it easier to choose the right cabin suitcase, a complete suitcase set or a spacious trolley suitcase for a longer holiday.

Three common pitfalls when buying a travel suitcase

1. Looking only at the number of inches

A 20-inch cabin suitcase does not have the same external dimensions with every brand. Wheels, handles and side edges all count towards the maximum dimensions. Always check the full measurements, including any protruding parts.

For example, a suitcase that is 52 cm high may appear suitable as hand luggage, but permitted dimensions vary by airline and ticket type. Check your airline’s current baggage rules before departure.

2. Confusing “lightweight” with maximum capacity

A low product weight is useful, but it says nothing about the usable interior space. A sturdy lining, internal divider and wheels all take up room. So, as well as the weight, look at the capacity in litres.

For a weekend trip, 28 to 40 litres may be sufficient. For a week-long holiday, around 65 litres is more practical. Families or travellers with lots of clothing may benefit from a suitcase of around 100 litres.

3. Not checking the wheels and lock

A 4-wheel suitcase is easy to manoeuvre on smooth floors, but the construction must also suit the way you intend to use it. A 2-wheel model is mainly pulled behind you and may feel more stable on uneven pavements. Also check that the lock is actually part of the suitcase and what type of fastening is used.

A TSA lock is particularly relevant when travelling with luggage that may go through security checks in the United States or other countries. It does not protect your suitcase against every form of theft and is no substitute for handling valuable items carefully.

Which specifications really matter?

Size and capacity

Use these guidelines as a starting point:

  • 28 litres: short business trip or one or two nights away.
  • 30 to 40 litres: weekend trip or travelling for a few days.
  • 65 litres: approximately one week, depending on clothing and shoes.
  • 100 litres: longer holidays or shared family use.

Pay attention to the difference between internal and external dimensions. With some suitcases, the actual internal measurements may differ from the stated external dimensions by approximately 1 to 2 cm.

Material: hard-shell suitcase or soft trolley?

A hard-shell suitcase protects its contents from external pressure and is easy to clean with a damp cloth. An ABS suitcase is generally relatively lightweight and has a smooth surface. According to KONO’s product description, the ABS material is designed to resist scratches and impact; this is a statement made by the brand and is not a guarantee that the suitcase will remain undamaged in all circumstances.

A synthetic leather suitcase, such as the ProWorld Travel Suitcase, has a different look and can also be cleaned with a damp cloth. However, its exterior is more sensitive to prolonged exposure to sunlight or sharp objects than many hard-shell suitcases.

Wheels, handle and compartments

Look out for:

  • 2 or 4 wheels: two wheels are suitable for pulling; four spinner wheels make turning and manoeuvring easier.
  • Telescopic handle: check the number of positions and whether the height suits your height.
  • Internal organisation: packing straps, a zipped divider and a mesh pocket help keep clothing and accessories in place.
  • Beauty case: a beauty case with a suitcase is useful for toiletries and can keep the main compartment free for other items.
  • Storage: a nesting suitcase set, where the suitcases fit inside one another, takes up less space in your cupboard.

Frequently asked questions about travel suitcases

What size travel suitcase can I take as hand luggage?

This depends on the airline, route, ticket type and any paid cabin baggage allowance. Measure the suitcase including the wheels and handle. A model approximately 52 to 57 cm high is often sold as a cabin suitcase, but always check your airline’s current conditions.

How long does a travel suitcase typically last?

Its lifespan depends on how it is used, the weight it carries, the surface it is used on and how you transport it. Wheels, zips and telescopic handles usually take the most strain. Avoid overpacking, do not pull a trolley suitcase unnecessarily over rough surfaces, and clean the exterior with a soft, damp cloth. The products mentioned are covered by at least the statutory two-year guarantee according to the product information; additional statutory rights may also apply.

Is a suitcase set better value than buying individual suitcases?

A suitcase set can be practical when you need several sizes. For example, you get a cabin suitcase for short trips and a larger suitcase for holidays. An individual travel suitcase makes more sense if you only use one size. So, do not compare the price alone: also consider the capacity, weight, wheels, lock and available storage space.
