When planning your next flight, one of the most important questions is: What carry-on dimensions are allowed? If packed incorrectly, your bag could incur unwanted additional costs at the airport or even be sent directly to the cargo hold. In this article, we'll clearly explain what carry-on dimensions and weights are currently accepted by airlines and how best to pack so your cabin baggage is accepted everywhere.
1. Why Carry-On Dimensions Are Important
Every airline determines the maximum size and weight for your carry-on baggage. These rules apply not only to suitcases – backpacks, trolleys, or weekenders are also measured. If a piece of luggage is too large or too heavy, you often have to check it as hold luggage for a fee. This can be expensive, especially with budget airlines. t-online
The dimensions are measured including wheels, wheel housings, handles, and pockets – so you cannot rely on only internal dimensions counting. sorglosfliegen.de
2. Standard Carry-On Dimensions in Europe
There is no uniform standard, but the most common dimensions for many airlines are:
55 × 40 × 23 cm (incl. wheels)
This size applies to many European airlines such as Lufthansa, Eurowings, Swiss, or Finnair for a regular cabin bag, often with a weight of max. 8–10 kg. t-online
40 × 30 × 20 cm (personal item)
Many airlines also allow a small personal carry-on item – e.g., a handbag, laptop bag, or document bag – which is stored under the seat. Typical dimensions here are approximately 40 × 30 × 15–20 cm. t-online+1
Examples (selection):
| Airline | Main Carry-On | Weight |
|---|---|---|
| Lufthansa / Eurowings | 55 × 40 × 23 cm | approx. 8 kg |
| Air France / KLM | 55 × 35 × 25 cm | approx. 10–12 kg |
| Ryanair | 40 × 30 × 20 cm (basic fare) | often no large cabin trolley included |
| British Airways | 56 × 45 × 25 cm | up to 23 kg |
| EasyJet | 45 × 36 × 20 cm | varies by fare |
3. Differences between Airlines and Fares
Even within the same airline, there can be differences:
-
Basic / Economy Light fares sometimes only allow small carry-on bags without a cabin trolley.
-
Budget airlines often charge additional fees for large carry-on luggage or a classic trolley. handgepaeckheld.de
For example: With Eurowings, a small carry-on item is usually included, but a large carry-on (up to 55 × 40 × 23 cm) may cost extra. Eurowings
4. Weight: How Light Must Carry-On Be?
There is no EU-wide uniform regulation. Common weight limits are:
-
8 kg for many European airlines
-
10 kg on some international connections

No weight restriction if only volume is checked (depending on the airline) NerdWallet UK
Tip: Even if no weight restriction is specified, make sure your bag can be carried by yourself, as most airlines require you to stow carry-on luggage in the cabin compartment yourself. hand-gepaeck.de
5. Packing Tips for Perfect Carry-On Dimensions
To ensure your carry-on is always accepted, consider the following:
✅ Always measure your bag: including wheels & handles
✅ Check weight at home: avoids stress at check-in
✅ Check soft bags: soft materials fit more easily into cabin compartments
✅ Extra compartment: Use a personal item like a laptop bag separately
