Six orientations
Length, width, and height are rotated before matching.
Measurement tip
Use the widest outside points of the bag. A soft backpack may compress, but the checker does not assume compression or ignore an oversized edge.
Packed measurement
Measure the bag as you will bring it to the airport.
Rotation check
A bag listed as 40 x 30 x 20 cm may still fit a 30 x 40 x 20 cm airline rule when it can be turned. The result is still a dimensional check, not a guarantee of acceptance.

CabinFit tries every length, width, and height orientation against the selected airline rule.
A personal item is the smaller bag that must fit under the seat in front of you — a backpack, laptop bag, handbag, or underseat duffel. Published limits typically range from 40 x 30 x 20 cm up to about 45 x 36 x 25 cm.
On most low-cost carriers it is the only bag included with a basic fare, which makes its exact dimensions the difference between boarding free and paying a gate fee.

There is no universal size — each airline publishes its own underseat limit, most falling between 40 x 30 x 20 cm and 45 x 36 x 25 cm. The table above shows current published limits for popular airlines.
Yes — any bag type qualifies as long as it fits the published dimensions when packed. A soft backpack that bulges past the limit counts as oversized at the sizer.
On most airlines an underseat bag is included with every fare, but a few basic tickets exclude even that. The fare column in the table shows which fare each limit applies to.
The personal item goes under the seat; the carry-on is bigger and goes in the overhead bin. On low-cost carriers the personal item is usually free while the overhead carry-on is often a paid extra.
