Choosing the Right Carry-On Bag

Stick to a maximum exterior dimension of 22 x 14 x 9 inches (56 x 36 x 23 cm) to comply with almost every major airline's carry-on policy. Always measure the wheels and handles, as these are frequently included by gate agents when checking size compliance.

1. Check your airline's specific limits. Before buying, check the 'Baggage Allowance' page on your frequent airlines' websites. While 22x14x9 is the industry standard, some budget carriers (like Ryanair or Spirit) have stricter dimensions for free bags.
2. Account for wheels and handles. Manufacturers often list the dimensions of the 'box' only. Use a soft measuring tape to measure the entire bag from the floor to the top of the extended handle and the widest part of the wheels.
3. Evaluate weight limits. Many international airlines enforce a weight limit, usually between 7kg (15 lbs) and 10kg (22 lbs). A lightweight hardside bag that weighs 8 lbs empty is a bad investment if you have a 15 lb limit.
4. Test the 'sizers'. If you are at the airport, put your bag into the metal sizer frame at the gate. If it doesn't drop in without force, it's too big, and you should be prepared to gate-check it.

Do I really need a carry-on with wheels?

Not necessarily. If you move through crowds or cobblestones, a backpack is easier. If you have back issues or travel strictly through terminals, a roller is better.

What happens if my bag is slightly over the limit?

If it fits in the overhead bin, you will likely get away with it. However, if the flight is full, gate agents will target the largest bags first to be checked into the cargo hold.
