On Ryanair, a bag with dimensions of 40cm x 20cm x 25cm (or the updated 40x30x20cm standard) is classified as a "Small Personal Bag." Unlike the larger 10kg overhead cabin bags, Ryanair does not officially state a weight limit for this small personal item. The primary requirement is that it must be able to fit completely under the seat in front of you. However, you should still be able to carry it comfortably yourself. While these bags are rarely weighed, gate agents may check them if they appear obviously oversized or so heavy that they cannot be safely stowed. If you have purchased "Priority & 2 Cabin Bags," you also get a larger 10kg bag (55x40x20cm) for the overhead locker. If your small bag is found to be over the size limits at the gate, you could be charged a fee of approximately €/£45.99 to have it placed in the aircraft hold. To avoid issues in 2026, ensure your "personal item" fits within the sizer at the gate, including any handles or wheels.
