55 × 40 × 20 cm – the large cabin bag for the overhead locker
55x40x20 cm is the bigger cabin bag — roughly 44 litres and up to 10 kg — that you get with Priority boarding on Ryanair, stored in the overhead locker rather than under the seat. It's the sweet spot for travellers who need more than a free under-seat bag holds but still refuse to check luggage in.
There's a detail worth knowing: this size is a little tighter than the "standard" cabin case sold in many shops, which is often 55 × 40 × 23 cm. Those extra few centimetres of depth can be enough for a bag to be refused at the gate on airlines that cap the depth at 20 cm. Every case in this collection is built to 55 × 40 × 20 cm including wheels and handles, so you get the maximum volume the rules allow without gambling on the sizer. Buy to this size and the same case slides comfortably inside the more generous cabin limits of airlines like Finnair, airBaltic and Wizz Air too.
Perfect for
- Week-long trips carried entirely as hand luggage
- The large Priority cabin bag allowance on Ryanair
- Maximising overhead-locker space without checking a bag
- One case that also fits within roomier airline cabin limits

Important about airline baggage rules
The 55 × 40 × 20 cm size is the large cabin bag on Ryanair (with Priority, up to 10 kg), but cabin allowances and weight limits differ by airline — many carriers allow a slightly deeper 55 × 40 × 23 cm bag, while others are stricter. Always check your airline's current baggage rules before departure, particularly the depth and weight, so your case qualifies.
