Ryanair Cabin Baggage 2026: Dimensions, Pitfalls to Avoid and Recommended Models

A Ryanair cabin bag can save you from extra fees, provided you follow the rules for your ticket to the millimetre. Yet many travellers discover at the boarding gate that their bag is too thick, their hard-shell suitcase won't fit under the seat, or the stated dimensions leave no margin for error.

Here are the points to check before buying a Ryanair cabin bag, a rucksack or a small suitcase for a weekend away, a business trip or a student stay.

Pitfalls to Avoid with an Underseat Bag

1. Don't Confuse the Free Small Bag with a Paid Cabin Bag

With the cheapest tickets, Ryanair usually includes a personal item to be placed under the seat. A larger bag, intended for the overhead locker, may require purchasing an additional option.

A model sold as "cabin" does not automatically benefit from the same conditions. Before you travel, check your booking, the fare type you've chosen and the dimensions permitted by Ryanair.

2. Relying Only on the Stated Dimensions

Wheels, handles, front pockets and padding can increase the actual size. Even a soft bag measuring 40 × 20 × 25 cm risks exceeding these limits if it's overstuffed.

To avoid nasty surprises, measure the bag when closed and packed, without compressing it excessively. Keeping a few centimetres of margin is always preferable, especially with a 20 L travel bag filled with clothes.

3. Choosing Volume Over Weight

A large capacity doesn't guarantee a better choice. An ABS cabin suitcase weighing 2.65 kg, for example, leaves far less weight available for your belongings than a soft bag weighing 0.36 kg. On short trips, a lightweight bag is also more comfortable to carry through stations, up metro stairs or during walking connections.

Criteria to Examine Before Ordering

Dimensions: The Non-Negotiable Criterion

For a Ryanair personal item, the models featured here are designed around the 40 × 20 × 25 cm format. However, this limit must be checked against the conditions applicable at the time of your trip.

Some more compact models measure 35 × 20 × 20 cm. They offer less space but slide more easily under a seat. As rules can vary from one low-cost airline to another, always consult the official website of the carrier in question.

Useful Volume and Internal Organisation

A 14 L travel bag can hold a tablet, documents, a book, earphones and a few lightweight clothes. For a weekend, a 20 L model will be more comfortable, provided you don't fill it to the point of distorting its shape.

Also remember to check:

  • the number of internal and external compartments;
  • the presence of a dedicated pocket for your passport or phone;
  • whether it opens flat, which is handy for organising clothes;
  • compatibility with a laptop or tablet;
  • whether it has a strap to attach the bag to a wheeled suitcase.

Materials and Modes of Transport

Oxford fabric and reinforced polyester are flexible and generally lightweight. Some bags are advertised as water-resistant: they'll withstand a few splashes, but they don't replace a proper waterproof cover.

A hard-shell suitcase in ABS offers better protection for its contents against knocks and is easy to manoeuvre thanks to its four spinner wheels. However, it is heavier and its dimensions must be checked carefully. A classic cabin-sized suitcase may require a paid option if it exceeds the limits for a personal item placed under the seat.

Frequently Asked Questions About Ryanair Cabin Baggage

What size should I choose for a Ryanair underseat bag?

The models in this selection mainly focus on the 40 × 20 × 25 cm format, while some bags measure 35 × 20 × 20 cm. The airline's policy can change and depends on the ticket you've chosen: check the conditions associated with your booking before you travel.

Is a 20 L travel bag enough for a weekend?

Yes, provided you travel light. It can hold two days' worth of clothes if you roll them, keep your toiletries to a minimum and only take one pair of shoes. The separate pockets of a cabin rucksack or holdall make it easier to access documents and electronic devices.

Is an ABS cabin suitcase suitable for a low-cost flight?

Yes, if its dimensions and weight match the allowance you've purchased. A hard-shell suitcase protects its contents effectively, but it's often heavier and less flexible than a soft bag. For the free item to be placed under the seat, pay particular attention to the length, width and depth of the suitcase once packed.
