What are the standard cabin baggage dimensions in 2026
Even though cabin bag dimensions vary from one airline to another, choosing a standard size can greatly simplify your travel experience. To avoid extra fees or being refused at boarding, always remember to check your carrier's specific guidelines. Check the detailed cabin baggage rules on the official website for a full understanding of all applicable restrictions.
Universal size accepted by most airlines
In 2026, the most common cabin suitcase size is 55 × 40 × 20 cm. This format is notably accepted by Air France, KLM, Lufthansa and Turkish Airlines. Note that these dimensions include the wheels and handles for an exact calculation.
- Standard dimensions 55 × 40 × 20 cm : a universal format recognized by most airlines, offering a good balance between capacity and compliance.
- Alternative 56 × 36 × 23 cm : this size is accepted by American Airlines or Etihad, and is particularly suitable for semi-rigid suitcases.
- Compact format 40 × 20 × 25 cm : this small bag is accepted almost everywhere, including by Ryanair, although its storage space is more limited.
- Measured externally : remember to include all protruding parts to avoid any unpleasant surprises at boarding.
If you plan to travel with several airlines, a suitcase measuring 40 × 20 × 25 cm remains the safest option. This compact format is also perfect if you are transporting an animal in carry-on baggage, since its carrier must absolutely fit in the compartment provided for that purpose.
Specific dimensions for European low-cost airlines
Low-cost airlines often impose very strict rules regarding what is allowed in the cabin. On Ryanair, the cabin baggage dimensions included free of charge are limited to 40 × 20 × 25 cm, unless you choose priority boarding. Wizz Air and EasyJet have their own standards, which may vary depending on the fare options selected.
These size restrictions require special attention when choosing your gear. If you travel regularly with Ryanair, it is best to invest in a suitable model to avoid having to pay extra for a checked bag. Soft bags are often more practical, as they fit more easily under the seat in front of you.
Alternative formats for long-haul flights and higher classes
For long-haul flights or premium class, the allowed dimensions are generally larger. British Airways, for example, offers enough space in economy class to fit a small bag containing your pet. Air France also allows more spacious formats depending on your booking class.
These more generous sizes let you bring more personal items for greater comfort during the flight. However, be sure to check the specific carry-on baggage rules for animals with your airline, as they remain strict, even in business class.
The semi-rigid suitcase is often the best choice for frequent travelers. Its flexibility makes it easier to fit the cabin bag into an already full compartment, without risking damage to your belongings or the aircraft interior.

Allowed weight and allowance for your cabin bag
The allowed weight of a cabin bag generally ranges from 7 to 23 kg, depending on your airline's policy and your booking class. Always weigh your suitcase when fully packed before departure to avoid unpleasant surprises and extra fees at check-in.
Weight limits by airline and class
Each carrier sets its own policy regarding cabin bag weight, so it is crucial to check it before every flight. Air France, for example, allows a bag weighing 10 to 12 kg in Economy class, compared with 18 kg in Business. British Airways is often more flexible, with a limit of 23 kg in economy class, which also includes one personal item.
Airlines such as Lufthansa are stricter and impose a maximum of 8 kg. EasyJet, meanwhile, generally applies a fixed limit of 15 kg regardless of the fare chosen by the passenger. To help you make sense of it all, check our complete guide to cabin baggage sizes, which also compares the advantages of hard and soft suitcases depending on airline requirements.
| Airline | Economy class | Premium class | Allowed dimensions |
| Air France | 10-12 kg | 18 kg | 55 × 35 × 25 cm |
| British Airways | 23 kg | 23 kg | 56 × 45 × 25 cm |
| Lufthansa | 8 kg | 8 kg | 55 × 40 × 23 cm |
| EasyJet | 15 kg | 15 kg | 45 × 36 × 20 cm / 56 × 45 × 25 cm |
| Ryanair | 10 kg (Priority) | 10 kg (Priority) | 40 × 20 × 25 cm / 55 × 40 × 20 cm |
Ryanair has a specific rule: the cabin bag weighing 10 kg is only allowed if you purchase the Priority option. Without this option, you are limited to one personal item of 40 × 20 × 25 cm. This constraint can affect your choice of suitcase and how you organize your belongings.
Tolerance margins applied by carriers
The cabin baggage tolerance varies greatly from one airline to another. Some are lenient and overlook a slight overage if the bag fits without issue, while others weigh every bag without exception. To travel with peace of mind, choose a lightweight suitcase weighing less than 1.5 kg empty, especially with the strictest carriers.
Choosing a soft, ultra-light bag gives you valuable extra room for your belongings without risking going over the limit. This detail becomes crucial if you are carrying an animal carrier, which can easily weigh up to 2 kg. A suitcase chosen well therefore gives you more flexibility while still fully complying with the rules in force in cabin.
Rules and dimensions for personal item carry-on luggage
Since summer 2025, a new unified European regulation has set a standard size of 40 × 30 × 15 cm for the free personal item. This new format, more generous with a 20% larger volume, lets you bring more items to place under the seat in front of you.
New 2025 European standard for hand luggage
The carry-on baggage rules now require precise dimensions of 40 × 30 × 15 cm for free transport. This standard applies to all airlines, including Air France and low-cost carriers. Your personal item can be a small bag backpack, a satchel, or any other container you place at your feet.
- Standard dimensions : the 40 × 30 × 15 cm format is allowed free of charge in cabin on all flights.
- Under-seat storage : this personal item must be able to fit under the seat in front of you to ensure safety during the flight.
- Optimized volume : you benefit from 20% more capacity compared with the old restrictions.
- Flexible weight : as long as your personal item fits properly under the seat, its weight is rarely checked.
The most basic tickets include only this free personal item, encouraging passengers to travel light. If you want to bring a larger main cabin bag (55 × 40 × 20 cm), you will usually have to pay extra. This policy is designed to speed up boarding and optimize space in cabin.
Higher fare classes allow you to add a second carry-on bag to be stored in the overhead compartment at no additional cost. This option offers welcome flexibility for carrying more personal items or traveling with an animal.
Difference between a personal item and a main cabin bag
It is essential to clearly distinguish the personal item from the main cabin bag. Carry-on rules create a clear separation between the small bag placed under the seat and the larger bag meant for the overhead bins. Understanding this difference saves you from having to check your bag at the last minute.
- Personal item : this small bag measuring 40 × 30 × 15 cm is always free, with no weight restriction.
- Main cabin bag : this 55 × 40 × 20 cm format is often subject to a weight limit and must be stored in the overhead bins.
- Bonus item : some airlines allow an extra handbag or another small item, if it is discreet and not bulky.
If you are traveling with an animal, its carrier generally counts as your only main cabin bag. The Oscar & Plume size S model can even serve as a universal personal item. The M size, which is roomier, is still allowed in cabin on most regular flights.
Exceptions and additional bags allowed free of charge
Fortunately, some items are not subject to the usual restrictions and can be brought on board at no extra cost. Parents can therefore bring a dedicated cabin bag containing everything needed for the baby. Likewise, medical or mobility equipment is exempt from size and weight limits.
The animal carrier is usually considered your only main cabin bag. It must strictly comply with the dimensions and maximum weight required by the airline. Lightweight Oscar & Plume models offer both comfort and full compliance with air travel standards.

Frequently asked questions
What is the standard size of a cabin suitcase in 2026?
For 2026, the standard size of a cabin suitcase remains set at 55 × 40 × 20 cm, a standard recognized by most airlines. These dimensions generally offer the best balance between storage capacity and maximum compatibility. However, to make sure your cabin bag is accepted even by the strictest low-cost airlines, choose a more compact format, around 40 × 20 × 25 cm.
Always remember to measure your bag including the wheels and handles, since these are often the parts that stick out and cause problems. It is risky to rely only on the manufacturer's stated dimensions, as they do not always take overall bulk into account.
What is the maximum weight allowed for a cabin bag?
The allowed weight for a cabin bag varies considerably depending on your travel class and the airline's policy. For example, Air France generally allows between 10 and 12 kg in Economy, and up to 18 kg in Business. Other carriers, such as British Airways, are more flexible with a limit that can reach 23 kg, while Lufthansa imposes a strict 8 kg limit.
On low-cost airlines such as Ryanair, only 10 kg is permitted if you choose the Priority option; without it, only a small bag is allowed. It is therefore crucial to weigh your personal item before departure and check the specific conditions for your flight.
What is the difference between a personal item and a main cabin bag?
The personal item, often considered an item, is a small bag that you can place under the seat in front of you. The main cabin bag, on the other hand, is roomier and must be stored in the compartment above the seats. Note: some low-cost tickets do not include this main bag, which may require you to pay extra for a checked bag.
If you are traveling with an animal, its carrier generally counts as your main cabin bag and must meet specific dimensions. In that case, you can usually still keep a small bag as a personal item, as long as it is allowed and meets the imposed limits.
