Biggest first.

It should. It has 5 cm to spare on its tightest side, and a stuffed front pocket usually adds 3 to 5 cm, so don't overfill the outside pockets.

British Airways' cabin bag limit is 56 × 45 × 25 cm, up to 23 kg.

Rimowa Essential Cabin, Away Carry-On, Osprey Farpoint 40 and American Tourister Soundbox Spinner 55 are right on the limit, so don't overpack.
