Ryanair allowance at a glance
| Option | Bag | Maximum size | Weight |
|---|---|---|---|
| Any fare | Underseat personal bag | 40 × 30 × 20 cm | No separate maximum stated on the cited policy page |
| Priority & 2 Cabin Bags | Second overhead bag | 55 × 40 × 20 cm | 10 kg |
Quick answer: a packed 40 × 30 × 20 cm backpack fits the free allowance exactly. Do not let pockets, straps or contents bulge beyond those measurements.
Does the free bag have to go under the seat?
Yes. Ryanair describes the included piece as a small personal bag that must fit under the seat in front. The free allowance is not an overhead trolley allowance.
What does Priority add?
Priority & 2 Cabin Bags adds one 10 kg cabin bag measuring up to 55 × 40 × 20 cm for the overhead locker, while the smaller personal bag remains included.
How to measure
Pack and close the bag first. Measure the three widest exterior points, including wheels, handles and bulging pockets. BagFit EU automatically rotates the dimensions mathematically, so their entry order does not affect the result.
