Yes, Ryanair is exceptionally strict with its small bag policy, and as of 2026, they have refined their enforcement to maximize efficiency and revenue. Every passenger is entitled to one "small personal bag" for free, which must fit under the seat in front of you. The dimensions are currently 40 x 30 x 20 cm (an increase from the previous 40 x 25 x 20 cm). Ryanair staff frequently use "baggage sizers" at the gate; if your bag does not fit comfortably without being forced, you will be charged a "gate-check" fee, which can be as high as £45 to £60 (€45–€70) to have the bag placed in the hold. They are particularly vigilant about "accessory" bags—if you carry a backpack and a separate handbag or laptop bag, they will often insist that one be placed inside the other before boarding. To avoid these fees, it is best to use a soft-sided bag that can be compressed and to ensure that wheels or rigid handles don't push the bag over the limit. Duty-free shopping bags are generally allowed as an additional item, but everything else must fit within your one-bag allowance.
