Measure the packed bag, not the empty shell
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.
Measure the bag as you will bring it to the airport.

CabinFit checks all six possible orientations
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.

What counts as a carry-on?
A carry-on — also called a cabin bag or hand luggage — is the larger cabin bag that rides in the overhead bin. Most airlines publish a maximum size around 55 x 40 x 20 cm, and many add a weight limit between 7 and 15 kg.
A size match does not prove ticket entitlement. Some fares include only a smaller underseat item, while an overhead bag may require a bundle or add-on. Check the allowance shown on your booking before you board.

Common questions before you pack
In Europe the most common published limit is 55 x 40 x 20 cm; US carriers typically use 22 x 14 x 9 in (about 56 x 36 x 23 cm). There is no universal standard, so always check the airline you actually fly with.
Measure the packed bag’s outside first, including wheels, handles and pockets. Some airlines publish a different measurement basis: Wizz excludes handles and wheels, with a separate wheel-extension condition. Check the selected airline’s source before comparing body-only and outside measurements.
Not necessarily. Carry-on entitlement varies by airline, fare, route and ticket conditions. Use the allowance shown on your booking and the airline's official baggage page.
If a packed bag exceeds the published frame, the airline may ask you to repack it, check it or pay the applicable baggage charge. CabinFit shows the measured margin but cannot predict the airport decision.
