*US carriers rarely weigh carry-ons, but you must lift it into the bin unaided. †Weight often includes your personal item. Low-cost and basic-economy fares vary most — always confirm on your airline's site.

How to pick a bag that always fits

Buy to 22 × 14 × 9 in (56 × 36 × 23 cm). It clears nearly every airline in the table — the main exceptions are strict European budget carriers, where a smaller underseat bag is safer.
Watch wheels and handles. Airline limits include them. A bag marked "21 inch" can measure 23 with wheels — measure the whole thing.
Soft-sided gives you margin. It squishes into a sizer; hard shells don't.
Flying a budget airline in Europe? Check weight, not just size — 7–10 kg limits catch people more than dimensions do.

Need a bag that fits everywhere?

A 22 × 14 × 9 in carry-on clears almost every airline on this list — and an underseat "personal item" bag covers the strict budget carriers.
