If anywhere outside North America, my general experience is that 22" carry-ons are considered large.
I don't fly frequently, although I plan to travel more frequently in the new year (maybe 5 trips or so, mostly domestic, one planned international). Domestically I'm on Alaska and Southwest a lot, and their limits appear fine for my needs, but I also fly United (points) and they seem to have one of the smaller size restrictions.
I've been carrying a Filson Medium duffel bag as my main travel bag that I carry on. Never stuffed to the brim but I've never had any issues with this bag. I guess it's harder to instantly gauge the size of a duffel versus hard luggage.
