40×30×20cm Cabin Bags

Every bag in this section measures 40×30×20cm. That is the size Ryanair publishes for its free under-seat bag (we checked Ryanair's help centre on 16 September 2026), and it sits inside easyJet's free under-seat size of 45×36×20cm.

There is no spare room on the Ryanair sizer, so don't overpack. Airlines change their rules, so check your own booking before you fly. Read which of our bags fit, and which don't.
