Ryanair is notoriously strict when it comes to checked baggage weight. Every passenger is allowed 1 checked bag, which must weigh less than 20kg. Passengers must ensure they adhere to this weight restriction, as exceeding it will incur an additional fee.

Ryanair is notorious for its strict enforcement of baggage policies in 2026. For carry-on luggage, while they rarely weigh "Small Cabin Bags" (personal items) as long as they fit under the seat, they are very vigilant about the 10kg limit for Large Cabin Bags. If your bag appears heavy or oversized, agents will often use scales and "sizers" at the boarding gate. For checked baggage, the rules are even more rigid; if your bag exceeds the pre-purchased limit (10kg or 20kg), you will be charged a steep excess fee—currently around €12 per extra kilogram. Ryanair does not allow for "pooling" weight across multiple passengers unless they are on the same booking. To avoid the high "airport prices" for extra weight, travelers are advised to weigh their bags at home and pre-book any necessary extra allowance via the Ryanair app, which is significantly cheaper than paying at the check-in desk or departure gate.
