Buying and evaluation criteria for hard shell suitcases

To help you find the right hard suitcase for your holiday, we have selected and briefly explained the most important criteria.

The criteria that you can use to compare hard suitcases with each other include:


Hard shell suitcases come in many different sizes. It can be difficult to find the right size for you. Many factors play an important role. The length of your trip is important, but it also depends on how much you plan to take with you. The individual sizes and recommendations are presented below.

  • Hard suitcase size S: These suitcases are mainly suitable for hand luggage. You can also take them on short trips. The packing volume is approx. 20-49 litres.
  • Hard suitcase size M: The medium size is particularly suitable for trips lasting up to 7 days. The height of the medium suitcase is 68 cm and it has a volume of 50 litres to 69 litres.
  • Hard suitcase size L: This is a very popular size and suitable for trips lasting up to 14 days. The volume is 70 litres to 89 litres and the suitcase is 74 cm high.
  • Hard suitcase size XL: The XL size is suitable for long trips of up to 21 days. It fits approximately 90 litres to 119 litres.
  • Hard suitcase size XXL: This is the largest hard suitcase you can buy. This size is perfect for long international trips, and you can also fit your holiday shopping in it. The packing volume is over 120 litres. The XXL hard suitcase is recommended for trips of 21 days to 28 days.


The weight of the hard shell suitcase also plays an important role when travelling. First of all, you have to pull your suitcase behind you and there are also airline regulations that have to be adhered to.

A lighter suitcase allows you to carry extra weight for your clothes.

Hard-sided suitcases are generally heavier than soft-sided suitcases. However, hard-sided suitcases are more robust and shock-resistant than soft-sided suitcases.

This is important for air travel. A large hard shell suitcase can weigh between 3 and 4 kilograms. Many manufacturers now make lightweight hard-shell suitcases.


Almost every hard shell suitcase is equipped with wheels. There are models with 2 wheels and models with 4 wheels. Which one is right for you?

Models with 4 wheels are especially suitable for commuters. If you are often at the airport or train stations, these suitcases are perfect for you. The hard shell suitcase with 4 wheels is flexible and manoeuvrable. Even on the train, you can push it in front of you and don't have to drag it behind you.

However, if you know that the ground on your trip is uneven, you should get a hard-sided suitcase with 2 wheels. 4 wheels tend to get stuck on the uneven ground and hold you up on your journey.


Hard cases come in many different designs, colours and patterns. There is something for everyone. You also have the option to have a hard shell suitcase printed according to your preferences.


With locks you can protect the contents of your hard case. This protects your suitcase from theft, which is important when travelling.

Many hard suitcases have pre-integrated TSA locks, so all you have to do is set a combination of numbers. The special thing about a TSA lock is that it can be opened at customs or at the airport with a master key if your suitcase needs to be searched.

In some countries, such as the USA, officials are allowed to open your suitcase without your permission, and if you don't have a TSA lock, they will break your lock.

If your hard suitcase does not have a built-in TSA lock, we recommend you get a TSA padlock.
