Cabin luggage dimensions 2026
12 major airlines compared
How large can your cabin luggage be? There is no single size limit that applies to every airline. Here you can compare the rules side by side—and see what you actually need to check before your trip.
Used by airlines including SAS, Norwegian, Finnair, Lufthansa, Eurowings, Wizz Air and airBaltic. But it is not a universal standard.
Fits within the small-bag size limit for every airline in this comparison.
Many airlines fall within this range, but easyJet allows 15 kg and some airlines combine the weight of both bags.
“Cabin luggage included” does not mean the same thing everywhere. With several airlines, the lowest fare includes only a small bag under the seat. A larger bag for the overhead locker may require an add-on or a more expensive fare.
Under the seat and in the overhead locker are not the same thing.
A personal item is the smaller bag that must fit completely under the seat in front of you. It can be a small backpack, handbag or laptop bag.
A larger cabin bag goes in the overhead locker. This is usually the bag an airline means when it lists dimensions around 55 × 40 × 20–25 cm.
Low-cost fares often include only the small bag. That is why checking the airline’s maximum dimensions is not enough—you also need to see what is included with your specific fare.
Open your booking and look for two things: the number of bags and where they are stored. If it only says “small bag,” “personal item” or “underseat bag,” a larger bag for the overhead locker is normally not included.

Dimensions normally include wheels, handles and protruding parts. These rules apply to flights operated by the respective airline. Different rules may apply to codeshare flights or connections.
Your bag is assessed based on how it looks when packed.
At the gate, you may be asked to place your bag in the airline’s baggage sizer. It must fit completely within the allowed space.
A soft backpack can be easier to fit than a hard-shell cabin bag, but only if it is not overpacked. The product dimensions do not help if exterior pockets or the contents make the bag bulge out.
Baggage sizers can also differ between airlines. A bag that fits with easyJet may not fit with Ryanair or KLM.
Four checks before departure.
Measure after you pack
Measure the bag at its maximum height, width and depth. Wheels, handles, side pockets and anything else that sticks out should be included.
Check both dimensions and weight
A bag can be the right size and still be too heavy. Norwegian, Finnair, KLM and airBaltic may apply a combined weight limit to both bags.
Check what your fare includes
The most common mistake is having a bag with the right dimensions but the wrong baggage allowance. Check the number of permitted bags in your booking.
Follow the strictest airline
If you are flying with multiple airlines, pack according to the smallest permitted dimensions and the lowest weight limit on your itinerary.
100 ml per container is the basic rule.
When travelling from an airport within the EU—as well as Norway, Iceland and Switzerland—each liquid container may normally hold no more than 100 ml. A larger bottle is not allowed simply because it is almost empty.
At most airports, the containers must fit inside a transparent, resealable bag with a maximum capacity of one litre. Exceptions include medications and baby food.
Screening technology varies between airports. At the new security checkpoint in Arlanda Terminal 5, 100 ml containers may remain in your cabin luggage and do not need to be placed in a one-litre bag. Always follow the signs and instructions at the checkpoint you are actually using.
Toothpaste, creams, gels, perfume, hair products, shaving foam and liquid or semi-liquid foods are also considered liquids.
Pack the things you need first where you can reach them immediately.
Your passport, phone, charger, headphones, medications and liquids should not require you to empty your entire bag at security.
If your larger cabin luggage is moved to checked baggage in the hold because of limited space, valuables, batteries and anything you need during the flight should already be in the bag under your seat.
Backpacks for different cabin luggage rules.
The more airlines you want to use the same bag with, the more important it is to choose dimensions with some margin. Always compare your fully packed bag with the rules in your own booking.

Quick answers about cabin luggage.
What dimensions apply to cabin luggage?
There is no single standard. 55 × 40 × 23 cm is common for a bag in the overhead locker, but Ryanair allows 55 × 40 × 20 cm, KLM and Air France allow 55 × 35 × 25 cm, and easyJet allows 56 × 45 × 25 cm.
Which cabin luggage size works with the most airlines?
For a small bag under the seat, 40 × 30 × 15 cm is a widely compatible size among the airlines in this guide. For larger cabin luggage, staying under 55 × 35 × 20 cm is safer across many airlines, but always check your booking.
Do wheels and handles count toward the dimensions?
Yes. The bag’s full exterior dimensions normally include wheels, handles, pockets and other protruding parts.
Can you bring both a personal bag and cabin luggage?
Only if your fare or an add-on includes both. With several airlines, the lowest fare includes only a small bag under the seat.
How much can cabin luggage weigh?
Common limits are 8 or 10 kg, but the rules vary. easyJet allows up to 15 kg per cabin bag, while some airlines apply a combined weight limit to both bags.
