How to measure your bag

Pack it first. A soft bag that fits empty can bulge past the limit once it’s full.
Measure the outside. Include wheels, handles and anything in the pockets.
Stand it up. Height is floor to the top of the handle when it’s pushed down.
Weigh it at home. Bathroom scales work: weigh yourself, then yourself holding the bag.

Airlines measure the bag as it is at the gate, packed.

Questions

Common cabin bag questions

Which airline has the biggest free under-seat bag?

Of the 53 airlines we track, Qantas allows the largest free under-seat bag on its cheapest fare: 34 × 48 × 23 cm (about 37.5 litres). The smallest is Singapore Airlines at 40 × 30 × 10 cm. See every airline side by side.

What is the standard cabin bag size?

There is no single standard, but the most common limits among the 53 airlines we track are 55x40x23 cm for the cabin bag (up to 50.6 litres) and 40x30x15 cm for the free under-seat bag (up to 18 litres). Weight limits are usually 7 to 10 kg when there is one. Pick your airline above for its exact numbers, or see cabin bag size in litres.

Is a cabin bag the same as hand luggage or a carry-on?

Yes. In the UK and Ireland the overhead bag is called a cabin bag or hand luggage; in the US and Canada it is a carry-on. The smaller bag that goes under the seat is the under-seat bag, also called a personal item. Airlines set a separate size for each.

Do wheels and handles count?

Yes. Airlines measure the outside of the bag, including wheels, handles and anything in the side pockets. Measure it packed.

Can I turn my bag sideways to fit the sizer?

Usually yes. What matters is that the bag fits the frame. That’s why we compare your longest side with the airline’s longest limit, the middle with the middle and the shortest with the shortest.

Which airlines include a cabin bag on the cheapest ticket?

On the cheapest fare we track, 29 of 53 airlines include an overhead cabin bag: Air New Zealand, Air Transat, AirAsia, American Airlines, Binter, British Airways, Cathay Pacific, Cebu Pacific, Delta Air Lines, Emirates, Etihad Airways, Gulf Air and more.
