How much does a carry-on suitcase weigh?
Souleymane Enok
Before heading to the airport, one question consistently arises: how much does my carry-on suitcase weigh? And more importantly, does my luggage comply with the limits imposed by my airline? While dimensions are often verified at the time of purchase, weight is a factor too frequently overlooked, which can lead to unpleasant surprises at boarding time.
The weight of a carry-on suitcase breaks down into two distinct elements. The empty weight of the suitcase itself, which varies depending on the material and size chosen. And the total weight allowed by your airline, including both the suitcase and its contents. A suitcase that weighs 3 kg empty with a 7 kg limit only leaves you with 4 kg for your belongings, which is much less than most travelers imagine.
In this article, we provide you with all the information regarding carry-on suitcase weights, limits by airline, and tips for optimizing your luggage without sacrificing the essentials.
Empty weight of carry-on suitcases: what you need to know before buying
The empty weight of a carry-on suitcase is one of the most important factors to check before any purchase, yet it is one of the least consulted by travelers who generally focus on dimensions and design. This is a mistake that turns out to be costly at boarding time when the total weight of the luggage exceeds the authorized limit even though the suitcase size is compliant.
The empty weight of a carry-on suitcase varies considerably depending on several factors. The first is the shell material. Rigid polycarbonate suitcases are generally the lightest on the market, with an empty weight between 1.8 and 2.5 kg for a standard 55 cm size. ABS suitcases are slightly heavier, between 2.2 and 3 kg, but also less expensive. Aluminum suitcases, prized for their robustness and premium aesthetic, are the heaviest, with an empty weight that can exceed 4 kg, making them problematic for airlines with strict 7 or 8 kg limits. Soft-sided suitcases made of nylon or polyester are generally lighter than their rigid counterparts, with empty weights between 1.5 and 2.2 kg.
The second factor is the size of the luggage. A 40 cm high carry-on naturally weighs less than a 55 cm model, even if both are made from the same material. This difference in empty weight can account for 300 to 500 grams depending on the model, which is far from negligible when your weight limit is set at 7 kg.
The third factor is the quality of the components. Wheels, telescopic handles, reinforced zippers, and integrated locks all add weight to a suitcase. An entry-level suitcase with basic plastic components will often be lighter than a high-end model with multi-directional aluminum wheels and an integrated TSA lock. Paradoxically, premium suitcases are sometimes heavier when empty despite the use of higher-quality materials.
To maximize the weight available for your belongings, the rule is simple: choose the lightest carry-on suitcase possible while remaining within the dimensions authorized by your airline. A suitcase that weighs 1.8 kg empty leaves you with 5.2 kg of content for a 7 kg limit, compared to only 4 kg with a 3 kg empty suitcase. This 1.2 kg difference represents several outfits or several extra days of travel.
Comparison table of empty weight by carry-on suitcase type
| Suitcase type | Material | Average empty weight | Pros | Cons |
|---|---|---|---|---|
| Lightweight rigid suitcase | Polycarbonate | 1.8 to 2.5 kg | Light, durable, waterproof | Higher price |
| Standard rigid suitcase | ABS | 2.2 to 3 kg | Affordable, sturdy | Heavier than polycarbonate |
| Premium rigid suitcase | Aluminum | 3.5 to 4.5 kg | Very durable, aesthetic | Too heavy for strict limits |
| Soft-sided suitcase | Nylon or polyester | 1.5 to 2.2 kg | Very light, flexible | Less protective |
| Soft cabin bag | Technical fabric | 0.8 to 1.5 kg | Ultralight, compressible | Less organized |
This table clearly illustrates that the choice of material is the most important lever for optimizing the empty weight of your carry-on suitcase. If you regularly travel with low-cost airlines that impose strict limits of 7 to 10 kg, investing in a polycarbonate suitcase or a quality soft bag is a decision that pays off quickly in avoided checked bag fees.
Weight limits by airline: 2026 comparison table
Knowing the weight limits authorized by your airline before packing your carry-on is an essential step to avoid unpleasant surprises at boarding. Because these limits vary considerably from one airline to another and can turn a peaceful trip into a stressful situation if your luggage is refused or subject to additional fees. Here is a precise status of weight policies by airline in 2026.
The first fundamental distinction to understand is that between legacy carriers and low-cost airlines. Legacy carriers like Air France, KLM, Lufthansa, or British Airways are generally more generous regarding carry-on weight limits. They frequently authorize a total weight of 10 to 12 kg for carry-on luggage, which leaves a comfortable margin for most travelers. These airlines often include this carry-on in all their fares without supplement, regardless of the travel class.
Low-cost airlines adopt a radically different approach. Ryanair, easyJet, Vueling, and Transavia have gradually tightened their carry-on policies to make them a source of additional revenue. Weight limits are stricter, often set between 10 kg with an option and 7 kg without, and checks are increasingly frequent and rigorous at boarding. The weight policy of these airlines should therefore be checked systematically before each flight because it can evolve from one season to the next.
An important point of vigilance concerns the weighing of carry-on luggage. Unlike checked luggage, which is systematically weighed at check-in, carry-on luggage is not always weighed at boarding. However, low-cost airlines have significantly reinforced their checks in recent years, and some, like Ryanair, regularly weigh carry-on luggage at the boarding gate. Oversized or overweight luggage can lead to fees ranging from 30 to 80 euros depending on the airline and the time of the check.
It is also important to note that weight limits generally apply to the entire carry-on, suitcase and contents included, wheels and handles included. Some airlines like Air France specify that the authorized total weight of 12 kg covers both the main piece of luggage and a personal item like a handbag or laptop simultaneously. Other airlines like easyJet offer different limits depending on the fare chosen and the type of luggage involved.
Comparison table of carry-on weight limits by airline 2026
| Airline | Carry-on weight | Personal item weight | Important notes |
|---|---|---|---|
| Air France | 12 kg total | Included in the 12 kg | Carry-on and accessory combined |
| KLM | 12 kg total | Included in the 12 kg | Same rules as Air France |
| Lufthansa | 8 kg | Not specified | Check possible at boarding |
| British Airways | 23 kg | Not specified | Very generous on carry-on |
| Ryanair | 10 kg with Priority | 10 kg without Priority | Frequent systematic checks |
| easyJet | Not specified | Not specified | Focus on dimensions rather than weight |
| Transavia | Varies by fare | Not specified | Check according to fare chosen |
| Vueling | 10 kg | Not specified | High penalties for exceeding |
| Wizz Air | 10 kg with option | Not specified | Paid carry-on without option |
| Turkish Airlines | 8 kg | Not specified | Regular checks at boarding |
This table confirms that low-cost airlines are significantly more restrictive than legacy carriers regarding carry-on weight limits. For travelers who regularly use airlines with 7 to 10 kg limits, investing in an ultralight carry-on suitcase made of polycarbonate or technical nylon is a decision that pays off quickly in comfort and avoided fees.

How to reduce the weight of your carry-on suitcase without sacrificing the essentials?
Reducing the weight of your carry-on suitcase without giving up the essentials is the art of light travel. And contrary to what many travelers imagine, this optimization does not necessarily involve major sacrifices regarding the contents of the suitcase. It starts first with smart choices about the suitcase itself, and then about how you select and organize your belongings.
The first lever is choosing an ultralight suitcase. As we saw previously, the empty weight of your suitcase can range between 1.5 and 4.5 kg depending on the material chosen. Opting for a polycarbonate suitcase or a soft bag made of technical nylon rather than an aluminum or thick ABS suitcase saves you up to 2 kg before you have even put a single item inside. These 2 kg saved on the suitcase weight are that many kilos available for your clothes, shoes, and accessories.
The second lever is the rigorous selection of clothing. The rule for experienced travelers is the travel capsule wardrobe, a limited set of versatile garments that can be combined to create a maximum number of different outfits with a minimum of pieces. Instead of taking seven different outfits for seven days, take five carefully chosen pieces that allow you to create ten distinct outfits through combinations. This approach significantly reduces the number of garments taken and therefore the total weight of your suitcase.
The third lever is choosing lightweight and compressible materials. Clothes made of merino wool, technical nylon, or lightweight polyester weigh two to three times less than their thick cotton equivalents while offering the same level of comfort and presentation. A merino t-shirt weighs about 100 to 120 grams compared to 200 to 250 grams for a thick cotton t-shirt. Multiplied by five or six t-shirts, this difference represents 500 to 800 grams less weight in your suitcase. Technical materials also have the advantage of drying quickly, which allows you to wash your clothes by hand in the evening and further reduce the quantity taken.
The fourth lever is reducing the weight of your toiletry bag. The toiletry bag is often the heaviest item in a carry-on suitcase in proportion to its volume. Several strategies allow for significant lightening. Opt for travel sizes of 30 to 50 ml rather than standard bottles. Replace liquid shampoo and shower gel with their solid equivalents, which weigh two to three times less and are not subject to the 100 ml rule. Buy products available at pharmacies or supermarkets on-site, such as toothpaste, deodorant, or sunscreen, rather than bringing them from home.
The fifth lever is wearing your heaviest items on the plane. This simple and legal tip allows you to lighten your suitcase considerably at the time of weight check. Wear your heaviest shoes, your thickest jacket or coat, and your heaviest sweater directly on you or carry them when boarding. These clothes worn on you are not counted in the weight of your carry-on luggage and can represent 2 to 3 kg less on the scale if your suitcase were to be checked.
The sixth lever is weighing your suitcase beforehand before heading to the airport. Investing in a small digital travel scale, available for less than 15 euros, allows you to accurately weigh your suitcase at home before departure and adjust its contents calmly if it exceeds the permitted limit. This prior check eliminates the risk of discovering an overweight issue during the airport inspection, where you have neither the time nor the possibility to comfortably adjust your luggage contents.
