Lufthansa Carry-On Size Guide

Quick Answer: Lufthansa Carry-On Size

Lufthansa allows one carry-on bag for many Economy and Premium Economy travelers, while Business and First Class travelers may be allowed two carry-on bags depending on route and fare. A Lufthansa carry-on bag should not exceed 55 x 40 x 23 cm, or about 21.7 x 15.7 x 9 inches, and should weigh no more than 8 kg / 17.6 lbs.

If you are flying Lufthansa, choosing the right luggage matters because Lufthansa uses international cabin bag dimensions rather than the common U.S. 22 x 14 x 9 inch carry-on size. A suitcase that works for some U.S. airlines may be too wide or too heavy for Lufthansa. This guide explains Lufthansa carry-on size rules, personal item guidance, checked bag basics, and the best luggage types to consider before your next Lufthansa flight.

Updated: May 2026. Airline baggage rules can change, so always confirm current requirements with Lufthansa before your flight.

What Size Carry-On Can You Bring on Lufthansa?

Lufthansa's standard carry-on size limit is 55 x 40 x 23 cm, which is about 21.7 x 15.7 x 9 inches. Lufthansa also lists a carry-on weight limit of 8 kg / 17.6 lbs.

This size is close to many international cabin baggage rules, but it is not exactly the same as the common U.S. 22 x 14 x 9 inch carry-on size. The main difference is that Lufthansa allows more width than some U.S. airlines but uses a slightly shorter height limit. If you fly multiple airlines on one trip, choose a compact carry-on that fits the strictest airline on your itinerary.

How Many Carry-On Bags Does Lufthansa Allow?

Lufthansa's carry-on allowance can depend on your cabin, route, and fare. Many Economy and Premium Economy travelers are allowed one carry-on item. Business and First Class travelers may be allowed two carry-on items. Some routes and fare types may have additional restrictions, so always confirm your allowance for your specific ticket before packing.

If you are traveling on a basic or light fare, check your Lufthansa booking carefully. Your free baggage allowance and checked baggage options may be different from a more flexible fare.

Lufthansa Personal Item Rules

Lufthansa may allow a small personal item in addition to your carry-on bag, such as a slim laptop bag, handbag, or compact travel item. The best personal item for Lufthansa is small enough to fit under the seat and not interfere with legroom or cabin safety requirements.

Because Lufthansa's carry-on weight limit is important, keep heavier items organized but do not overload your personal item. A slim laptop bag, small backpack, compact tote, or low-profile underseat bag is usually a safer choice than a bulky travel backpack.

Does Lufthansa Weigh Carry-On Bags?

Lufthansa lists a carry-on weight limit of 8 kg / 17.6 lbs. Your carry-on may be checked for size or weight, especially on full flights, smaller aircraft, busy international routes, or when cabin baggage enforcement is strict.

For Lufthansa travel, a lightweight carry-on is one of the smartest choices. If the suitcase itself is heavy before you pack, it becomes much easier to exceed the 8 kg limit. Choose lightweight luggage and pack only what you need in the cabin.

Can You Bring a Backpack on Lufthansa?

Yes, you can bring a backpack on Lufthansa if it fits within your allowed baggage rules. A small backpack may work as a personal item if it fits under the seat, while a larger backpack may need to count as your main carry-on bag.

The safest backpack for Lufthansa is compact, soft-sided, and not overpacked. If your backpack is too thick, too tall, or too heavy, it may need to be checked or count against your cabin baggage allowance.

Can You Bring an Underseat Bag on Lufthansa?

Yes. An underseat bag can be useful on Lufthansa if it is compact enough to fit under the seat in front of you. Underseat bags work well for essentials like your passport, medication, laptop, chargers, headphones, snacks, and travel documents.

For Lufthansa flights, choose an underseat bag that is low-profile and lightweight. Avoid personal items that become bulky when packed, especially if you are also trying to stay under the carry-on weight limit.

What Happens If Your Lufthansa Carry-On Is Too Big?

If your Lufthansa carry-on is too large, too heavy, or cannot be safely stored in the cabin, it may need to be checked. This can lead to additional fees, gate-checking, extra airport time, and waiting at baggage claim after arrival.

To avoid problems, measure your bag before your trip and weigh it after packing. Include wheels, handles, side grips, outside pockets, and attachments when checking size. If your itinerary includes a partner airline, confirm that your bag fits every airline on the trip.
