Are you looking for a suitcase for a longer trip, or do you want to be sure that a large model makes sense for your flight? Then it is smart to look not only at the number of litres, but also at the outside dimensions of the suitcase, including the wheels and handle.
What are common dimensions for checked baggage?
There is no universal standard size for checked baggage that applies everywhere. However, many airlines often use a maximum total dimension of 158 cm. This means that the total of the length + width + depth must not exceed 158 cm.
For example:
- 77 x 52 x 29 cm = 158 cm in total
- 75 x 48 x 30 cm = 153 cm in total
- 78 x 54 x 32 cm = 164 cm in total and may therefore be too large
When measuring, protruding parts usually count too, such as wheels, handles and protective edges. That is why it is best to always check the stated outside dimensions of the suitcase, rather than looking only at its capacity in litres.
What does 158 cm checked baggage mean?
Checked baggage measuring 158 cm does not mean that your suitcase may be 158 cm high. It refers to the total of three sides:
- Length
- Width
- Depth
For many travellers, this is the most important starting point when comparing suitcase dimensions for checked baggage. If an airline website states that the maximum checked baggage dimensions are 158 cm, always check the complete outside dimensions of the model.
How large can a 23 kg suitcase be?
A 23 kg suitcase does not automatically have one fixed size. The 23 kg refers to the maximum weight, not directly to the dimensions. In practice, many travellers choose a suitcase that is approximately 75 to 78 cm high, often with a capacity of about 90 to 120 litres. This size is often suitable for longer holidays and regularly falls within common checked baggage requirements. Looking for a specific option? Take a look at our 23 kg suitcases.
A practical example of a large size is a suitcase measuring 77 x 52 x 31 cm with a capacity of 93 litres. This gives a good idea of what a spacious checked suitcase can look like. Always check whether the total outside dimensions comply with your airline's rules.
Which suitcase should you choose for 20 kg or 23 kg of checked baggage?
As a guideline, you can use this overview:
| Suitcase type | Approximate height | Capacity | Often suitable for |
|---|---|---|---|
| Medium-sized suitcase | 67-72 cm | 60-85 litres | Shorter to medium-length trips, often suitable for approximately 15-20 kg of luggage |
| Large suitcase | 75-78 cm | 90-120 litres | Long trips and approximately 20-23 kg of checked baggage |
If you are unsure between a medium-sized and a large suitcase, this usually applies: choose a medium-sized suitcase if you want to travel compactly, and a large suitcase if you need more space for longer trips, several outfits or belongings for the whole family. Keep in mind that a larger suitcase can become too heavy more quickly. A practical way to stay within the limit is to choose lightweight suitcases.
Flying with an airline that allows 25 kg of checked baggage? Then a 25 kg suitcase is a logical choice.
How to measure a suitcase for checked baggage correctly
Want to know whether a suitcase is suitable for checked baggage? Always measure the outside of the suitcase:
- Height: from the floor side to the top, including the wheels and handle
- Width: the widest point from left to right
- Depth: from the front to the back, including protruding parts
Then add these three measurements together. This shows you immediately whether you stay within a limit such as 158 cm. This is especially important for hard-shell suitcases and expandable models, because the outside dimensions can increase when you use the extra packing space.
Checked baggage dimensions by airline: what should you look out for?
Are you looking for checked suitcases for a specific airline such as KLM, TUI, Corendon, Transavia or Ryanair? Always check the current rules for exactly that type of baggage. The main differences are usually:
- Maximum total dimensions
- Maximum weight per suitcase
- Number of permitted pieces of luggage
- Additional rules for unusually large suitcases
For Ryanair, it is especially important not to confuse the different types of baggage. Use these dimensions consistently:
- Free small personal bag: 40 x 30 x 20 cm
- 10 kg cabin suitcase: 55 x 40 x 20 cm
- 20 kg checked baggage: maximum 80 x 120 x 120 cm
- 23 kg checked baggage: maximum 80 x 120 x 120 cm
These are therefore different dimensions from those for cabin baggage. If you search for Ryanair checked baggage dimensions, first check that you are really looking at checked luggage.
Which checked suitcase is usually a safe choice?
If you are looking for a suitcase that is a practical choice for many flights, you will often end up with large suitcases of approximately 75 to 77 cm high. This size usually offers enough space for longer trips without immediately falling into the extra-large category.
Medium-sized suitcases can also be a smart choice if you do not want to take unnecessary volume with you. They are often easier to handle and help you stay within a weight limit more easily. The best size therefore depends on two things: your airline's baggage rules and how much you are actually taking with you.
Are you unsure between several sizes? Then it is often more convenient to choose based on both the outside dimensions and the capacity. At ByMetz, you will find checked suitcases, medium-sized suitcases and suitcase sets, making it easier to compare which size best suits your trip.
