Ryanair is notorious for being exceptionally strict regarding the weight and dimensions of all luggage, including cabin bags and checked suitcases. For checked luggage, every bag is weighed at the "Bag Drop" counter; if your bag exceeds the weight you pre-purchased (usually 10kg or 20kg), you will be charged a significant "Excess Baggage Fee" per kilogram, which can often cost more than the original flight ticket. Regarding cabin luggage, while they may not weigh every small personal item, they frequently use metal "sizers" at the boarding gate. If your bag looks overstuffed or heavy, agents will ask you to place it in the sizer. If it does not fit or if the agent deems it too heavy for safe handling in the overhead bins, you will be forced to pay a "Gate Bag Fee" (typically €45 to €70) and your bag will be placed in the aircraft hold. In 2026, many Ryanair gates are equipped with digital scales integrated into the sizers to ensure 100% compliance. To avoid these fees, it is highly recommended to weigh your bags at home and ensure they meet the specific limits listed on your booking confirmation.
