Official Ryanair Rules 2026
Your Ryanair personal bag must measure a maximum of 40x20x25 cm . It must fit under the seat in front of you. Staff regularly check this using a metal template.
Unlike a standard 55x40x20 cabin bag, the 40x20x25 bag is the only size included free of charge without a Priority option.
Actual usable volume
A 40x20x25 bag theoretically offers 20 liters. In practice, the usable volume depends on the internal structure and rigidity.
For example, the Ryanair 40x20x25 model is designed precisely to utilize every centimeter allowed.
Why this format is strategic
- Avoid extra charges
- Fast boarding
- Optimal mobility
- City trip 2–4 days
- Low-cost compatibility
Models like the Lee Cabin Travel Bag or the AeroNomad are designed to meet these constraints.
