When travelling by plane, especially with low-cost carriers like Ryanair, it pays to plan your luggage well in advance. One of the most frequently chosen ticket add-ons is checked baggage — a suitcase that goes into the aircraft hold and does not have to fit in the cabin. It is a particularly useful solution for longer trips, when there is no way to squeeze everything into a small backpack or a cabin case.
Checked baggage on Ryanair can be purchased during the ticket booking itself or later — through the app or the website. The most popular option is the 20 kg limit, which is usually enough for a one-week or even two-week trip, provided you plan your packing well.
It is worth knowing that Ryanair has fairly strict baggage rules — especially regarding weight. Exceeding the permitted limit by even a few hundred grams can mean a surcharge at the airport. What is more, the airline regularly updates its rules and conditions — so before every trip, make sure your suitcases still meet the carrier's requirements.
In this guide I will explain how to choose the right suitcase for 20 kg checked baggage, what to look for in the dimensions, whether wheels and handles count, and what you should know to avoid stress at the airport. If you are still deciding on your cabin bag as well, check our companion guide to Ryanair cabin baggage dimensions and tips.
Current Ryanair rules for checked baggage (2026)
Ryanair is an airline famous for low prices, but also for a rather rigorous approach to baggage. If you are planning a flight and considering adding checked baggage, familiarise yourself with the current rules to avoid stress at the airport and extra fees. In 2026 the airline still offers checked baggage of up to 20 kg — the option most frequently chosen by passengers — and you can now purchase up to three 20 kg bags per passenger. There is also a newer 23 kg option (one per booking), but it can only be added at the time of booking, not afterwards.
The weight limit is clearly defined: a maximum of 20 kilograms per piece of checked baggage. This limit must not be exceeded — not even by a few hundred grams. Ryanair weighs suitcases very scrupulously at the bag-drop desk. Exceeding the permitted weight means an immediate surcharge per extra kilogram: currently around €/£9 per kilo if you buy the extra allowance online up to two hours before departure, and roughly €/£11 per kilo at the airport. Being just 3 kg over can therefore cost more than the bag itself. That is why it is worth weighing your suitcase at home and leaving yourself a small margin. Note that no single item may exceed 32 kg — heavier pieces are refused for safety reasons.
The dimensions of Ryanair checked baggage are defined more generously than for cabin baggage, but that does not mean any suitcase will do. The official maximum size of a 20 kg Check-in Bag is 80 × 120 × 120 cm (height × width × depth). This is the total external size of the suitcase, measured together with wheels, handles and any protruding elements.
Keep in mind that although Ryanair does not routinely measure checked suitcases, a size check can happen — especially at smaller airports or with unusually large luggage. If a suitcase turns out to be too big or does not fit on the baggage belt, there may be problems with accepting it, or it may need to be sent as special baggage, which involves additional fees.
To sum up: in 2026 the standard checked bag on Ryanair is a suitcase weighing up to 20 kg with maximum dimensions of 80 × 120 × 120 cm; in practice it is worth staying comfortably within those limits and choosing suitcases built to recognised standards. And remember: the bag is definitely weighed — every single time. By the way, the same 20 kg format exists at the competition — see our sister guide to checked baggage 20 kg on Wizz Air if you fly both carriers.
Checked suitcases that fit Ryanair's rules
Which elements count when measuring a suitcase?
When choosing a suitcase for checked baggage, many people focus solely on capacity or look only at the shell itself, forgetting that airlines — including Ryanair — take the entire external outline of the suitcase into account. It is a common mistake that can cost a lot of nerves, and sometimes even oversize surcharges. In this section I will explain exactly what is included in the measurement and how to measure your suitcase correctly at home.
What is measured? Everything that protrudes beyond the main body of the suitcase. The total size includes:
- height — from the base of the wheels to the highest point (often the telescopic handle or the rigid top handle),
- width — measured at the widest point, including side handles, protruding pockets or reinforcements,
- depth — from the front to the back wall of the suitcase, together with bulges, locks and wheels.
In short: every centimetre counts that could affect whether the suitcase fits on the baggage belt or in the standard cargo space of the aircraft hold. Even small protruding elements can make a difference.
A frequent mistake among travellers is going only by the suitcase's 'capacity' in litres — e.g. 80 L, 90 L. That parameter is helpful when planning how much to bring, but it says nothing about whether the carrier will accept the case. Equally misleading is looking only at the size of the shell itself, without wheels and handles — and it is precisely those elements that often make a suitcase too big.
How to measure a suitcase correctly
It is very simple, but it has to be done precisely:
- Stand the suitcase upright on the floor, in its transport position (the way it stands when you pull it behind you).
- Use a tailor's tape measure or a regular builder's tape.
- Measure the height — from the floor (i.e. from the wheels) to the highest point.
- Measure the width — at the widest point, including handles or side bulges.
- Measure the depth — from the front to the back wall, together with wheels and any external pockets.
- Check each value against the carrier's limits to get the full picture of the suitcase's size.
If you are buying a new suitcase online, look for descriptions like 'external dimensions including wheels' — that is closest to what airlines care about. If that information is not given, ask the seller or choose a trusted brand that transparently lists all dimensions.
How to choose the right suitcase for 20 kg baggage on Ryanair
Choosing the right suitcase for checked baggage is one of the most important steps before a flight. If you are flying Ryanair and plan to buy the 20 kg bag, make sure the suitcase not only fits within the permitted limit, but is also practical, durable and comfortable to use. Below are the key points to consider. For a broader look at specific models, see our ranking of which suitcase to choose for Ryanair — dimensions, weight and best models.
Optimal suitcase capacity — how many litres is 'ideal'?
For 20 kg checked baggage, suitcases with a capacity between 75 and 95 litres work best. That range comfortably fits clothes, toiletries and accessories even for a longer trip — one week, two weeks or more if you pack well. Smaller suitcases may prove insufficient; larger ones tempt you to overpack, which risks exceeding the weight limit.
Remember: the suitcase should be not only roomy but also light in itself. The less it weighs empty, the more you can pack inside without risking surcharges.
Material: hard or soft suitcase?
This is one of the most common dilemmas. Each solution has its advantages:
- Hard suitcase — usually made of polycarbonate, ABS, polypropylene or modern composite materials. Cases made of HPX™ Resin copolymer polypropylene are especially recommended — the material is extraordinarily resistant to impacts, cracking and temperature swings. Suitcases like these provide excellent protection even with intensive use.
- Soft suitcase — lighter and more flexible, often with extra pockets. It tolerates 'stuffing in' those last few items better, but protects the contents worse, especially with less-than-gentle handling by airport staff.
If you fly often, I definitely recommend a hard suitcase — it is an investment in peace of mind and baggage safety. We break the whole debate down in detail in hard or soft luggage — what to choose.
Suitcase construction: what really matters
Beyond capacity and material, pay attention to the technical details. A good suitcase is one that cooperates with you on the road — it does not drag, pull crooked or jam.
- Wheels: four spinner wheels are best, letting you steer the case lightly and smoothly in any direction. Two-wheeled suitcases are cheaper but less comfortable over longer distances.
- Handles: it helps if the suitcase has side and top handles — it makes carrying easier, especially on stairs or when loading into a car boot.
- TSA lock: more and more suitcases have a TSA-compatible lock — it allows airport security services to open the case without damaging it. It is not mandatory in Europe, but it can come in handy if you plan travels further afield.
Quality vs price — why it pays to invest
You can of course buy a cheap suitcase 'for now', but ask yourself: how many trips will it survive? Low-quality suitcases often end their career after one or two flights — wheels crack, handles break, the material comes apart. And then you have to buy another one…
That is why, if you travel even a few times a year, I recommend investing in a solid, branded suitcase that will serve you for years. Check its parameters, construction and reviews — a well-chosen suitcase genuinely makes life on the road easier. And if you are looking for something durable and designed for intensive use, take a closer look at Peli suitcases — their resilience and functionality make a real difference.
Alternatives for every trip length
An example of the ideal 20 kg suitcase: Peli Air 1615
Choosing the right suitcase is not only a matter of capacity — quality, durability and compliance with airline requirements matter too. If you are looking for a solution that will last through years of intensive travel, take a look at the Peli Air 1615.
Size and weight — a perfect fit
The Peli Air 1615 suitcase has external dimensions of 82.8 × 46.7 × 28 cm, which means it fits comfortably within Ryanair's checked-baggage envelope of 80 × 120 × 120 cm — handled flat in the hold, its longest side sits far below the 120 cm width limit, and the remaining sides leave a wide margin. Wheels and handles are included in those dimensions — which matters a lot at bag drop.
Its own weight is around 6 kg, which leaves a solid 14 kg allowance for personal items, equipment or clothes. With good organisation — that is enough even for a longer trip.
Capacity and functionality
The suitcase offers around 80 litres of capacity — optimal space for packing within the 20 kg limit. With a well-thought-out interior layout, you will easily fit clothes, shoes, a toiletry bag and other essentials.
Why it is worth it
- Exceptional durability — made of ultra-tough HPX™ Resin, resistant to impacts and extreme transport conditions.
- Sealing — ideal for transporting sensitive equipment (e.g. photo, audio, electronics). Protects against moisture, dust and damage.
- Wheels and handles — solid, well balanced, allowing comfortable handling even fully loaded.
- TSA lock — essential for international travel — lets customs officers inspect the case without the risk of damaging the lock.
The Peli Air 1615 is not an ordinary suitcase — it is a choice for people who travel often and do not want to worry about the safety of their luggage. For Ryanair flights, it is one of the best solutions you can consider. And if you want to pay less for the bag itself, check our trick for saving up to €40 on every Ryanair checked suitcase.
Is it worth using a home scale and tape measure before the trip?
Preparing your luggage before a trip is not just about packing — it is also about making sure your suitcase stays within the weight limit and its dimensions comply with airline requirements. That is why it pays to invest in a home scale and a tape measure, which will help you avoid stress at the airport.
How to avoid airport stress — weigh before you leave
Nothing stresses a traveller more than discovering that their baggage weighs more than the permitted 20 kg. If you do not want your holiday to start with trouble at bag drop, weigh your suitcase carefully before the trip and check its dimensions. That way you will be sure to avoid excess-baggage fees and will not be caught off guard by airport staff.
Which apps and gadgets can help?
These days there are many tools that help you measure baggage weight and size precisely. Here are a few popular options:
- Travel scales — small, handy devices that let you quickly weigh luggage at home. Just hang the suitcase on the scale's hook to get a reading. Most models measure up to 50 kg, so you can easily weigh both checked and cabin baggage.
- Luggage tape measures — simple tools for measuring the length, width and depth of a suitcase. Choose one with clear centimetre markings to avoid measurement mistakes.
- Mobile apps — there are also apps that help monitor baggage dimensions and weight. Some let you keep digital notes of your suitcases' sizes, which can be helpful when planning future trips.
Differences between home and airport scales — the margin of error
Although a home scale is a convenient tool, remember that readings can differ between your scale and the one used at the airport. Check-in scales are usually more precise, and differences can result from how the suitcase is loaded, the type of floor or slight calibration differences. That is why you should always weigh your baggage with a small buffer — e.g. 1–2 kilograms of margin. This prevents unknowingly exceeding the permitted limit.
The benefits of weighing your suitcase carefully before departure are enormous. You will not only avoid unnecessary stress at the airport but also save on excess-baggage fees — at roughly €9–11 per extra kilo, the maths adds up quickly. Preparing in advance is the key to a successful trip!
The most common mistakes when choosing a suitcase for Ryanair
Choosing the right suitcase for Ryanair is not just a matter of looks — it is also about compliance with the airline's requirements. Even small mistakes can lead to problems at check-in, excess-baggage fees or trouble at security. Here are the most common traps to watch out for.
A suitcase too big in size (even if it fits by weight)
One of the most common mistakes is choosing a suitcase that meets the weight limit but exceeds the maximum permitted dimensions. For Ryanair checked baggage, the official envelope is 80 × 120 × 120 cm. Even if the suitcase weighs less than 20 kg, oversized dimensions can cause problems at bag drop. Before you commit to a specific model, check its dimensions carefully, including wheels and handles.
A suitcase made of heavy materials (it eats into your weight limit)
Choosing a suitcase made of heavy material can quickly consume part of your weight allowance on the suitcase itself instead of its contents. Hard cases made of materials like steel or thick plastic can weigh as much as 5–6 kg, which with a 20 kg limit leaves little room for clothes and other items. Instead of heavy materials, choose light but durable suitcases, such as those made of HPX™ Resin copolymer polypropylene, which combine strength with low weight.
No TSA lock — problems at inspection
When travelling to the United States, and to many other countries, it is very important that your suitcase has a TSA lock. A TSA lock allows customs services to inspect the baggage without damaging the case. Suitcases without such a lock may be forcibly opened by security services, which can damage the contents or the suitcase itself. That is why a TSA-lock suitcase is a matter of both safety and convenience on international trips.
A suitcase with protruding elements — it snags, and is harder to measure and position
Protruding suitcase elements, such as handles, side pockets or decorations, can be a problem both during measurement and in transport. They can snag on other bags on the baggage belt, leading to damage to the suitcase or other items. What is more, protruding elements can push the case beyond the required dimensions, resulting in surcharges or exceeding the limit. That is why it pays to choose suitcases with a cleaner construction, without unnecessary add-ons that make measuring harder.
Avoiding these mistakes will save you time and money and ensure a comfortable journey without unnecessary complications. Remember — a well-chosen suitcase is the key to a hassle-free trip with Ryanair.
Cabin cases with TSA locks
Does Ryanair checked baggage have to have a TSA lock?
Although Ryanair does not require checked baggage to have a TSA lock, it is definitely recommended. A TSA (Transportation Security Administration) lock is a special type of lock that allows security services to open a suitcase without damaging it. While it is not mandatory, it is worth investing in a suitcase equipped with one to avoid potential problems during baggage inspection.
TSA increases safety — especially on connecting flights outside the EU
A TSA lock is particularly important on international flights, especially when travelling to the United States or with connections in countries with strict baggage regulations. During baggage checks at US and international airports, security staff may need to open a suitcase for inspection. Cases with TSA locks allow services to open the bag safely without destroying the lock or the case, ensuring greater security and faster inspection.
The role of TSA in potential baggage searches
A TSA lock also plays an important role in the event of a baggage search. When your suitcase is randomly selected for inspection and does not have a TSA lock, the services must remove the old lock or damage the case to carry out the check. That can lead to the unpleasant situation of having to repair the suitcase after returning from a trip. A TSA lock guarantees the baggage will be opened in a controlled way, without damage. So although it is not a Ryanair requirement, a TSA-lock suitcase is a matter of convenience and safety.
To sum up, a TSA lock is not mandatory for Ryanair checked baggage, but having one significantly raises the level of security and makes travelling easier, especially on international flights with connections. It is worth considering a suitcase with such a lock to avoid potential complications at bag drop.
Packing a 20 kg suitcase — how to optimise the space
Packing a 20 kg checked suitcase can seem like a challenge, especially when you want to bring everything you need. Remember, though, that good space management inside the case saves precious room and weight — which can prove crucial at bag drop. Here are a few proven methods to optimise your packing so everything fits without exceeding the weight limit.
Organisers, vacuum bags, flat packing
One of the most effective ways to save space in a suitcase is organisers and vacuum bags. Organisers keep the luggage tidy by dividing it into sections, allowing better placement of clothes, shoes and accessories. Vacuum bags are a great solution for clothing, especially jackets, jumpers and other bulky garments. Thanks to them, clothes not only take up less space but are also protected from moisture and dirt.
Flat packing is another method that reduces baggage volume. Here, you flatten clothes as much as possible, avoiding folding them into thick creases. This makes better use of the available space and reduces the volume of items in the suitcase.
Avoiding excess toiletries and 'just in case' items
One of the biggest packing mistakes is bringing too many toiletries and 'just in case' items. Analyse carefully what you will genuinely need during the trip and what can stay at home. Limiting toiletries and accessories to the absolute minimum not only saves space but also reduces baggage weight.
Instead of full-size cosmetic packaging, choose small travel versions or decant essential products into smaller containers. Also consider buying products at your destination (e.g. shampoo or shower gel). This approach helps avoid a surplus of things you will not use while travelling.
Moving the heaviest items to your cabin baggage (if possible)
If you can, move the heaviest items to your cabin baggage to minimise the weight of the checked bag. The checked suitcase is best for items that do not strain the cabin limits (e.g. clothing, shoes). In your cabin bag, meanwhile, you can put heavier objects such as books, electronics or documents, as long as they stay within Ryanair's permitted cabin dimensions.
Thoughtful packing of your cabin baggage can also free up space in the checked suitcase, letting you bring more without exceeding the weight limit. This helps you avoid the excess-baggage fees charged when the checked bag is over the limit.
To sum up, good space management in the suitcase is the key to successful packing of checked baggage. Organisers, vacuum bags and flat packing are proven methods for optimising space. It is also important to avoid unnecessary items and excess toiletries, and to consider moving heavier objects to the cabin bag. With these simple tricks you will easily fit all the essentials without exceeding Ryanair's weight limit.

Summary — current Ryanair checked baggage rules
Choosing the right suitcase for checked baggage is a key element of any trip, especially with an airline like Ryanair, which has specific requirements for dimensions and weight. Under the current 2026 rules, a standard checked bag on Ryanair must not exceed 20 kg, and the suitcase must fit within the official envelope of 80 × 120 × 120 cm — including wheels, handles and every protruding element. Exceeding the weight limit means a per-kilo surcharge (around €9 online, €11 at the airport), and no single item may weigh more than 32 kg. There is also the option of up to three 20 kg bags per passenger, plus a 23 kg bag available only at booking.
An important element in choosing a suitcase is also its material, construction and functionality. Hard suitcases made of materials such as HPX™ Resin polypropylene offer better protection, which is crucial when travelling with valuable items. The right number of wheels and handles improves transport comfort, and TSA locks provide security, especially on international trips. It is worth investing in a suitcase that will last for years, avoiding cheap products that may prove flimsy and prone to damage.
When travelling with Ryanair, also remember the frequent weight and size checks, particularly at bag drop. So before the trip, weigh and measure your suitcase carefully to avoid unnecessary airport fees. A well-chosen suitcase, matched to the weight and size limits, is the key to a calm journey.
To sum up, when planning a trip with Ryanair, it is important not only to choose a suitcase of the right size, but also to look after its functionality and durability. Make sure your case meets the airline's current requirements, and attention to detail — weight, dimensions and security — will make your journey smooth and comfortable.
