Lufthansa is the airline that wrote the 55 x 40 x 23 rule, or at least the one that made it the European default, and in 2026 its carry-on policy is still the benchmark that other legacy carriers quote. It is also the airline where the weight limit, not the size limit, catches most passengers: 8 kg is not generous once a hard case is on the scale. This is the 2026 version of our Lufthansa carry-on guide, rewritten from the ground up: what the numbers are, what the three Economy fares actually change, what you get in Business and First, what happens on a full flight, and which cabin cases fit the sizer with weight left for your things. ✈️
We sell Peli cases and we say which ones fit; the rules are Lufthansa's own, current as we write, and the airline changes them without much notice, so confirm on lufthansa.com before you fly. If you are comparing carriers rather than packing for this one, our guides to Austrian, KLM and Ryanair use the same structure.
The 10 things to know
1. The cabin bag: 55 x 40 x 23 cm and 8 kg 📏
One piece of hand baggage per passenger in Economy and Premium Economy, with maximum dimensions of 55 x 40 x 23 cm including wheels and handles, and a maximum weight of 8 kg. Both limits apply together: a bag within the dimensions but at 9 kg is over the limit, and so is a 7 kg bag that is 25 cm deep. Lufthansa's sizers at the gate are built to these numbers and, unlike a soft bag, a hard case either fits or it does not. Every Peli cabin case we list gives its external dimensions with wheels on the product page for exactly this reason, and all three we recommend below sit inside the envelope.
2. The personal item: 40 x 30 x 10 cm 👜
In addition to the cabin bag, every passenger may bring one personal item of up to 40 x 30 x 10 cm: a handbag, a laptop bag, a small backpack. It goes under the seat in front. This is the item that saves 8 kg trips: a laptop, charger, book and the day's essentials in the personal item weigh nothing against the cabin bag's limit, so pack the heavy flat things there and the clothes in the case. Lufthansa also accepts a foldable garment bag of up to 57 x 54 x 15 cm in place of the cabin bag, which suits suit-and-shirt business travel better than a case does.

3. Economy Light, Classic and Flex: what changes and what does not 🎫
Lufthansa sells European Economy in three fares, and the difference that matters here is simple: all three include the same cabin bag and the same personal item. Light is the fare without a checked bag, and it is where people get caught, because they assume the cheapest fare means a smaller cabin allowance the way it does on Ryanair or Wizz Air. It does not. What Light removes is the hold bag, seat selection and flexibility; the 55 x 40 x 23 cm, 8 kg cabin bag and the personal item are the same on every Economy fare. Classic adds a checked bag and Flex adds changes and refunds. If you fly with one case and a personal item, Light is the right fare and the cabin rules do not change; if you need the hold, Classic is cheaper than adding a bag to Light later. On long-haul, Economy fares follow the same cabin allowance with a checked bag included in most of them.

4. Business and First: two bags, same size and weight 💼
Business and First Class passengers may bring two pieces of hand baggage, each up to 55 x 40 x 23 cm and 8 kg, plus the personal item. The allowance is by piece, not by total weight: two 8 kg bags, not one 16 kg bag. It is also worth knowing that on busy short-haul flights with Business cabins, overhead space is still shared with Economy, and a second cabin bag may be gate-checked like anyone else's when the bins are full. Status members in Economy do not get a second cabin bag; the second piece is a class benefit, not a Miles & More one.
5. The 8 kg limit is the one that bites ⚖️
Lufthansa weighs cabin bags more often than most legacy carriers, usually at check-in for passengers who go to a desk, and at the gate when a flight is full or a bag looks heavy. The arithmetic is unforgiving: a conventional hard cabin suitcase weighs 2.5 to 3.5 kg empty, a protective case more, and 8 kg total leaves between 4 and 5.5 kg for contents. That is a long weekend of clothes, or a camera kit, not a week. Three tactics work. Put the dense flat items in the personal item, which is not weighed against the 8 kg in practice. Choose the lightest case that does the job. And weigh the packed case at home with a luggage scale rather than discovering the number at the gate. Our guide to packing a suitcase under 10 kg is written for exactly this limit.
For the three Peli cases in the block above, the honest numbers are: the ATX HC22 is the travel suitcase with a lined interior and four spinner wheels, and the one to weigh against conventional cabin cases; the Air 1535 is 3.95 kg empty, leaving about 4 kg for contents; the 1510 is roughly 5.4 kg with its foam and is bought for what it protects, not for what it carries. If the case is for clothes, the HC22 or the Air 1535; if it is for equipment, the Air 1535 or the 1510. The full comparison is in Peli 1510 vs Peli Air 1535.
6. What happens on a full flight: gate-checking 🛄
On full flights Lufthansa gate agents ask for volunteers to have cabin bags loaded into the hold free of charge, and if there are not enough volunteers they assign it, starting with the last boarding groups. The bag is tagged at the gate and returns on the belt at your destination; you do not pay, but you lose access to it for the flight and it goes through the same baggage system as any checked bag. Two consequences. Nothing valuable, fragile or battery-powered should be in a cabin bag that could be gate-checked, which is what the personal item is for. And a hard case with latches survives a surprise trip through the hold in a way a soft bag does not, which is a quiet argument for the cases in this article. What the hold actually does to a bag is in what really happens to your suitcase after check-in.
7. Liquids, electronics and batteries on board 🔋
Security rules are not Lufthansa's but they decide what goes in the bag. Liquids in containers of 100 ml or less in a one-litre bag, unless the departure airport has the newer CT scanners that allow more; how liquid limits work at different airports lists where. Laptops and tablets come out of the bag at most German airports. Power banks and spare lithium batteries must be in the cabin, never in the hold, with the usual 100 Wh threshold, and a bag that is gate-checked must have them removed first; the rules are in our power bank guide. Lufthansa's own list of what is prohibited on board follows the standard European one, which we cover in prohibited items in hand baggage.

8. Exceeding the limits: what it costs 💶
A cabin bag that is over size or over weight at the gate is checked into the hold as an additional bag at the airport rate, which is higher than buying a checked bag when booking and much higher on a Light fare that included none. Lufthansa publishes its excess and additional baggage fees by route on its site and they change; the useful rule is that anything you know you will need in the hold is cheaper to add at booking than at the desk, and far cheaper than at the gate. How to avoid baggage fees walks through the arithmetic across carriers.
9. Lufthansa Group: the same rules on Swiss, Austrian, Brussels and Eurowings ✈️
Lufthansa's cabin allowance is shared across the group, with small local variations. Swiss, Austrian and Brussels Airlines use the same 55 x 40 x 23 cm and 8 kg cabin bag and the same 40 x 30 x 10 cm personal item, and the same two-piece allowance in Business. Eurowings, the group's low-cost carrier, also uses 55 x 40 x 23 cm and 8 kg for its cabin bag, but its Basic fare includes only the personal item, so the cabin bag is paid, the way it is on Ryanair. If your itinerary mixes Lufthansa and Eurowings flights, check each segment; the case that flies free on the Lufthansa leg may be a paid add-on on the Eurowings one. Austrian's version, with its own quirks, is in our Austrian Airlines guide.
10. Long-haul: same bag, different bins 🌍
On long-haul Lufthansa flights the cabin allowance does not change, but the aircraft do, and the overhead bins on an A350, A340 or 747 are larger than on an A320 shuttle. The practical effect is that a 55 x 40 x 23 cm case that had to go in wheels-first on a short-haul flight goes in on its side with room to spare, and gate-checking is rarer. What is stricter on long-haul is the weight check at the desk, because every long-haul passenger checks in with a bag and every bag passes the scale. What to expect on board is in Lufthansa on long-haul routes.

Organise the inside so the 8 kg goes on your things, not on packaging
How to pack 8 kg that feels like 12
- Heavy and flat into the personal item. Laptop, tablet, charger, book, documents. It goes under the seat and is not weighed against the cabin bag.
- Wear the heaviest layer and the heaviest shoes. A jacket and boots on you are two kilograms not in the case.
- Roll, do not fold, and use packing cubes so the case is packed once, not repacked at security.
- Liquids at 100 ml or bought after security; full-size toiletries are weight and a confiscation risk at once.
- One pair of shoes in the case, at most, filled with socks and chargers.
- Weigh the packed case at home. A luggage scale costs less than one gate-checked bag.
- Batteries and valuables in the personal item, so that a gate-check on a full flight costs you nothing.

Lufthansa against the others
| Airline | Cabin bag in the base fare | Size | Weight |
|---|---|---|---|
| Lufthansa | Yes, on every fare | 55 x 40 x 23 cm | 8 kg |
| Eurowings | No, paid on Basic | 55 x 40 x 23 cm | 8 kg |
| KLM / Air France | Yes | 55 x 35 x 25 cm | 12 kg |
| Ryanair | No, with Priority only | 55 x 40 x 20 cm | 10 kg |
| Wizz Air | No, with Priority only | 55 x 40 x 23 cm | 10 kg |
| Emirates | Yes | 55 x 38 x 20 cm | 7 kg |
The pattern: Lufthansa gives you the bag on every fare and takes it back in kilograms. Ryanair and Wizz Air give you more kilograms and charge for the bag. KLM and Air France give you the most weight and a slightly different shape. Which one suits you depends on whether your problem is space, weight or money.

If you booked Classic: checked cases for the hold
Frequently asked questions
What size carry-on does Lufthansa allow in 2026?
One bag of up to 55 x 40 x 23 cm and 8 kg, plus one personal item of up to 40 x 30 x 10 cm, on every Economy fare including Light. Business and First allow two bags of that size and weight.
Does Lufthansa Economy Light include a cabin bag?
Yes. Light removes the checked bag, seat selection and flexibility; the cabin bag and personal item are the same as on Classic and Flex.
Does Lufthansa weigh hand luggage?
Yes, more often than most legacy carriers: at check-in desks routinely and at the gate on full flights or when a bag looks heavy. The 8 kg limit is enforced.
What happens if my Lufthansa cabin bag is over 8 kg?
It is checked into the hold as an additional bag at the airport rate, or you repack into the personal item until it passes. On a full flight it may be gate-checked free regardless.
Which Peli case fits Lufthansa's cabin size?
The ATX HC22, the Air 1535 and the 1510 all sit inside 55 x 40 x 23 cm with wheels and handle. For clothes and the 8 kg limit, the HC22 or the Air 1535; for equipment, the Air 1535 or the 1510.
Can I bring a laptop bag in addition to my cabin bag on Lufthansa?
Yes. The 40 x 30 x 10 cm personal item is in addition to the cabin bag on every fare and class.
Are the rules the same on Swiss, Austrian and Eurowings?
Swiss, Austrian and Brussels use the same cabin bag and personal item. Eurowings uses the same size and weight but does not include the cabin bag in its Basic fare.
The short version
Lufthansa gives every passenger a 55 x 40 x 23 cm, 8 kg cabin bag and a 40 x 30 x 10 cm personal item on every fare, two bags in Business and First, and enforces the kilograms more than the centimetres. Put the heavy flat things in the personal item, choose a case that leaves weight for your clothes, weigh it at home, and keep batteries and valuables out of anything that could be gate-checked. Do that and the sizer, the scale and the gate agent are all on your side. 🌍
