A good checked-luggage suitcase gives you enough packing space without travelling unnecessarily large or heavy. On this page you'll find medium and large suitcases suitable for air travel, from short holidays to longer trips. Unsure between 20 or 23 kg, hard or soft shell, or which size is most practical? ByMetz is happy to help you choose.
Checked luggage is mainly about the right balance of dimensions, empty weight, durability and ease of use. So it's smart to look beyond litres or looks and consider how you travel and how much you actually pack.
Which checked-luggage suitcase suits your trip?
For most flights you'll end up with a medium or large suitcase. Which size fits best usually depends on your allowed kilos, trip length and how compactly you pack.
| Situation | Often smartest choice | Why |
|---|---|---|
| About 20 kg checked luggage | Medium suitcase | Often enough space for 1–2 weeks and helps stay within the weight limit |
| About 23 kg checked luggage | Large suitcase | Useful for longer trips, multiple seasons or extra shoes and coats |
| Packing for two or bringing a lot | Large suitcase or suitcase set | More volume and better organisation when packing |
A medium travel suitcase is often the safest choice if you want to travel efficiently and avoid overweight. A large checked-luggage suitcase is convenient when you travel longer or need more space for clothing, accessories or items for multiple people.
Watch dimensions and airline rules
A checked suitcase should not only have enough capacity but also fit your airline's rules. Many travellers use a general guideline of a maximum total dimension of 158 cm (length + width + height). Rules can still vary by airline, route and fare type.
Always check what your carrier allows for dimensions and weight before departure. That prevents surprises at check-in and makes choosing the right suitcase much easier.
What to consider when choosing a checked-luggage suitcase?
Empty weight
The lighter the suitcase itself, the more kilos you have left for your contents. This makes a big difference with a 20 kg allowance. Consider lightweight suitcases if you want to keep as many kilos as possible for your items.
Material
Many travellers pick hard-shell suitcases for checked luggage because checked bags can take a beating in transit. Popular materials include polypropylene and ABS for strength and protection.
Interior organisation
A practical interior helps you stay organised. Think of separate compartments, packing pockets and straps to keep clothes in place. Use packing cubes to pack smart and make the most of the space.
Manoeuvrability
On airports, a smoothly rolling suitcase is a pleasure, especially in larger sizes. A good wheel system and comfortable telescopic handle make a difference. 4-wheel suitcases (spinners) make heavier checked luggage easier to manoeuvre.
Medium & large suitcases for checked luggage
ByMetz offers suitcases in sizes suited to checked luggage, including medium suitcases, large suitcases and suitcase sets. Choose based on trip length, packing style and permitted weight.
Looking for a suitcase for around 20 kilos, a medium case is often a logical start. If you need extra room for 23 kg or longer trips, a large suitcase is usually more practical. Travelling with family or combining sizes? Suitcase sets are handy.

FAQ
How big can a suitcase be for checked luggage?
It varies by airline, but many travellers use a 158 cm total dimension guideline. Always check your carrier's rules, as limits and conditions may differ.
Which suitcase is good for 20 kg checked luggage?
For 20 kg, a medium suitcase is often the most practical choice. You usually have enough space for a 1–2 week holiday while staying better within the weight limit.
Which suitcase is suitable for 23 kg?
For 23 kg many travellers choose a large suitcase. It's handy for longer trips, changing climates or when you bring extra shoes, coats or gifts.
Is a hard or soft checked-luggage suitcase better?
For flights, hard-shell suitcases are often chosen because checked luggage needs protection against knocks in transit. Soft suitcases can be useful for packing flexibility, but hard models are generally preferred for protection.
