Ryanair Small Bag Size – Exact Dimensions, Weight & Rules

Travellers flying with Ryanair often encounter conflicting information about the exact dimensions of the free small bag allowed on board. Official sources cite one set of measurements while third-party guides and user forums mention another. This article lays out the verified facts, explains where the confusion comes from, and provides a clear picture of what Ryanair enforces at the gate in 2025 and 2026.

What are the exact dimensions of Ryanair’s small bag?

Ryanair’s official help centre states that every fare includes one small personal bag that must fit under the seat in front. The dimensions listed there are 40 x 30 x 20 cm. However, several third-party luggage brands and travel guides, including Antler and Riut, reference a different measurement: 40 x 20 x 25 cm. This discrepancy is a frequent source of confusion for passengers.

Key facts about the small bag size

• The official Ryanair help centre gives 40 x 30 x 20 cm as the permitted size for the free small bag.
• Third-party guides such as Antler and Riut list 40 x 20 x 25 cm, which some users interpret as the same bag measured in a different orientation.
• The Ryanair Official Bag Rules do not mention a 40 x 20 x 25 cm dimension anywhere on the current help-centre page.
• A 2025 official YouTube video from Ryanair demonstrates the sizer with a bag that fits 40 x 30 x 20 cm and does not reference the alternative size.
• User discussions on Reddit suggest that the confusion arises from how a bag is oriented when placed in the sizer – laid flat or upright.
• No weight limit currently applies to the free small bag, but a 7 kg rule has been announced for a future date.
• Priority passengers can bring the small bag plus a larger cabin bag of 55 x 40 x 20 cm weighing up to 10 kg.

Does Ryanair have a weight limit for the small bag?

As of early 2026, Ryanair does not enforce a weight limit on the free small personal bag. The airline’s published rules focus exclusively on size and the requirement that the bag fits under the seat. Enforcement centres on whether the bag passes the physical sizer test at the gate.

Current policy on weight

According to the Ryanair help centre and the Ryanair Bag Sizer Explained (YouTube) video, no maximum weight is specified for the free small bag. Passengers are not required to place their small bag on a scale during boarding.

Is a 7 kg limit coming?

Several third-party sources, including the luggage brand Riut, report that Ryanair has announced a future 7 kg weight limit for the small bag. The exact date of implementation has not been confirmed, and the official help centre page does not yet mention this change. Travellers should monitor the airline’s official site for confirmation.

Does Ryanair weigh small bags at the gate?

Current user reports and official materials indicate that Ryanair does not weigh the small bag during boarding. The check is visual and dimensional: the bag must fit into the sizer. If the bag fits, no weight measurement is taken.

How strict is Ryanair about bag size enforcement?

Ryanair enforces its bag size rules at the gate using a bag sizer. Staff may ask passengers to place their small bag into the sizer before boarding. The requirement is that the bag fits entirely inside without protruding handles, wheels, or straps.

What happens if the bag doesn’t fit the sizer?

If the small bag fails the sizer test, the airline may refuse boarding or place the bag in the hold for a fee. According to the official Ryanair YouTube video, the penalty for an oversize small bag can be up to €60. If a priority passenger’s larger cabin bag fails, the fee can reach €75.

Is there any room for “squishing”?

User reports on Reddit indicate that gate agents sometimes allow a degree of compression for soft-sided bags. A fabric backpack that can be pressed into the sizer may be accepted, while rigid-shell bags that exceed the dimensions even slightly are likely to be rejected. Official guidance from Ryanair states that the bag must fit without force, which suggests that squishing is not formally permitted but may be tolerated in practice depending on the agent.

When are bag checks carried out?

Checks typically happen at the boarding gate, not at check-in. Passengers who appear to be carrying oversized items may be asked to step aside and test their bag in the sizer. The check is visual and immediate.

Ryanair small bag vs Priority & 10kg cabin bag: what’s the difference?

Passengers who purchase a standard fare are limited to one small bag (40 x 30 x 20 cm) that must go under the seat. Those who add Priority & 2 Cabin Bags to their booking can bring the same small bag plus a larger cabin bag stored in the overhead locker.

Priority cabin bag dimensions and weight

The larger cabin bag allowed with priority is consistently stated as 55 x 40 x 20 cm with a maximum weight of 10 kg. This is the standard carry-on size across many European low-cost carriers.

Can you bring both bags with priority?

Yes. With priority boarding, passengers may carry one small personal bag (under the seat) and one larger cabin bag (overhead locker). Both items must meet the respective size limits. The small bag remains limited to 40 x 30 x 20 cm even when travelling with priority.

How does Ryanair small bag size compare to other airlines (easyJet, British Airways)?

Ryanair’s free small bag at 40 x 30 x 20 cm is among the most restrictive among European carriers. easyJet allows one free cabin bag of 45 x 36 x 20 cm (no weight limit), which is slightly larger in two dimensions. British Airways permits a free handbag or laptop bag (40 x 30 x 15 cm) plus a larger cabin bag of 56 x 45 x 25 cm (23 kg) on most fares, offering significantly more capacity for passengers who need it.

Ryanair’s dimension of 40 x 30 x 20 cm means the total volume is 24,000 cm³, compared to easyJet’s 32,400 cm³. British Airways’ combined allowance offers even more flexibility. For budget-conscious travellers who travel light, Ryanair’s small bag is workable, but the airline’s strict enforcement sets it apart from carriers that measure less rigorously.

Ryanair small bag policy updates 2025–2026: what has changed?

The small bag allowance has been a subject of discussion and speculation in 2025 and 2026. The following timeline summarises the key milestones based on available sources.

1. Pre-2025: The small bag size was consistently quoted as 40 x 30 x 20 cm with no weight limit. Enforcement was present but less widely discussed.
2. July 2025: Some third-party sources reported that Ryanair had adjusted the free personal bag allowance to 40 x 30 x 20 cm, while others suggested a new EU-style standard of 40 x 30 x 15 cm was being adopted. The official help centre continued to show 40 x 20 x 25 cm in some snippets.
3. Early 2026: Luggage brand Antler updated its guide to reflect 40 x 20 x 25 cm. Riut published a guide stating that a 7 kg weight limit had been announced but not yet implemented.
4. Future (unconfirmed): Ryanair is expected to introduce a 7 kg weight limit on the small bag, though no official date has been set.

Which aspects of the small bag policy are certain and which remain unclear?

Why do different sources show different dimensions?

The discrepancy between 40 x 30 x 20 cm and 40 x 20 x 25 cm likely arises from how a bag is oriented when measured. A bag that is 40 cm long, 30 cm wide, and 20 cm deep when placed flat may be described as 40 x 20 x 25 cm when stood on its side if the depth and height are transposed or if the bag has slightly tapered dimensions. Ryanair’s physical sizer is designed to accept bags in a specific orientation, and some luggage manufacturers advertise their products as fitting Ryanair’s sizer based on a different measurement convention.

It is also possible that the official help centre page has been updated at different times for different regions, causing search snippets to display older or alternate dimensions. The Ryanair Official Bag Rules page remains the authoritative source, and it currently lists 40 x 30 x 20 cm for passengers who view it directly.

Additional context is available from Antler: Ryanair Baggage Allowance 2026, which notes the 40 x 20 x 25 cm dimension, and from Cabin Zero’s guide, which discusses the EU-style standard alignment. MyBaggage’s summary also covers the 2025–2026 changes.

Summary: what travellers need to know about Ryanair’s small bag size

Ryanair’s free small bag is officially 40 x 30 x 20 cm, with no current weight limit. Enforcement is carried out at the gate using a bag sizer, and bags that do not fit may incur a fee of up to €60. A future 7 kg weight limit has been reported but not confirmed by the airline. For travellers who need more space, the Priority & 2 Cabin Bags option adds a 55 x 40 x 20 cm bag weighing up to 10 kg. The safest strategy is to treat the official 40 x 30 x 20 cm limit as strict and choose a bag that clearly meets those measurements.
