Choosing a suitcase set: how to compare size, material and smart extras

A new suitcase set may seem easy to choose at first glance. Yet many travellers buy a model that is not suitable for their flight, is too heavy for the baggage allowance or proves less practical after just a few trips. Product descriptions often tell you how many wheels, compartments and locks a suitcase has, but not always what that means for your situation.

Pay particular attention to these three common pitfalls:

  • A cabin suitcase that is not accepted by every airline. Dimensions are sometimes stated including the wheels and handle, while airlines set their own maximum sizes.
  • A large capacity that provides little usable packing space. A thick shell, interior wall or awkward layout can reduce the available room.
  • Marketing claims about being “lightweight” or “strong” without clear figures. Look at the weight, material, dimensions and construction rather than relying on the description alone.

Which specifications should you check?

1. Size and capacity: 20, 24 or 28 inches?

A 20-inch suitcase is often used as a cabin-size case. For example, the KONO 20-inch suitcase measures 57 x 38 x 24 cm, including the wheels and handle, and has a capacity of approximately 40 litres, according to the product information. This may be suitable for a short trip, but always check your airline’s current rules. “Suitable for many major airlines” is not a general guarantee for every flight or ticket class.

A 24-inch suitcase is generally intended for checked baggage for around a week. The NINETYGO Danube is listed as measuring 66 x 45.5 x 25.5 cm, with a capacity of 38 litres in the product specification. Check that the stated dimensions and capacity relate to the same model and size.

For families or longer holidays, a 28-inch model may offer more space. With a set, it is useful to have several sizes included, but think in advance about where you will store them at home.

2. ABS or polycarbonate?

An ABS suitcase generally has a hard plastic shell and can combine a low weight with protection against impacts during normal travel. According to the product information, the KONO suitcase set uses ABS and weighs 2.62 kg for the 20-inch model, 3.18 kg for the 24-inch model and 4 kg for the 28-inch model.

A polycarbonate suitcase uses PC, a different type of plastic. According to the product description, the NINETYGO Danube has a hard PC shell with a textured exterior. The 20-inch model is listed with a weight of 3 kg and a capacity of 38 litres.

Bear in mind that the material alone does not determine how long a suitcase will last. Zips, stitching, handles, wheel attachments and the way you load the case also play a part. A scratch-resistant finish will not prevent visible signs of use in all circumstances.

3. Wheels, handle and lock

A suitcase with 360° wheels can turn in multiple directions. This is practical at stations, airports and on smooth hotel floors. Four spinner wheels make it possible to roll the case sideways, but small wheels may be less comfortable on cobbles or uneven pavements. Check whether the model has double wheels and whether the wheel housings feel sturdy.

A classic two-wheel trolley suitcase can roll steadily when you pull it behind you. According to the product information, the ProWorld Travel Suitcase has two wheels, a telescopic handle, a capacity of 28 litres and a weight of 2.26 kg.

A suitcase with a TSA lock can be opened during security checks in certain countries by authorised inspectors using a designated system. The lock does not protect against every risk and is not a substitute for handling valuable items carefully. Choose a personal code and do not keep it with the suitcase.

Practical checks before ordering

Use this quick checklist:

  1. Measure the suitcase including the wheels and handle and compare the size with your airline’s requirements.
  2. Decide whether you need a lightweight suitcase, a sturdy shell or simply plenty of capacity.
  3. Check the net weight: a larger suitcase is not automatically practical if you quickly reach the baggage allowance.
  4. Examine the wheel construction and telescopic handle.
  5. Check whether a beauty case with trolley strap is actually included in the set rather than merely shown as an accessory.
  6. Read the returns policy, warranty information and current product details before ordering.

Frequently asked questions about suitcase sets

Is a 20-inch suitcase always suitable as hand luggage?

No. The term 20 inches is only an indication. Airlines have different size and weight limits. Measure the complete product and check the conditions for your ticket and airline.

How long does a hard-shell suitcase last?

Its lifespan depends on how it is used, how heavily it is packed, the surface it is used on and how it is handled by baggage handlers. ABS and polycarbonate can provide protection during normal use, but no material can prevent all damage. Do not overload the zip, wheels or handle, and store the suitcase somewhere dry.

Is a suitcase set better value than buying individual cases?

That depends on how often you use the different sizes. A set can be practical for families or travellers taking trips of varying lengths. If you usually travel with hand luggage only, you may get better value from one cabin-size case that fits your needs. Also consider how much storage space you have at home.
