A bag that fits the overhead bin can still fail the size limit on the ticket.
Turn three bag dimensions and a size limit into linear inches, the amount over the limit, and a status.
Travellers measuring a bag before a flight, a move, or a freight booking.
Use the source document or official route that applies to your situation. This guide does not contact another person or verify external information.
Measure the longest side, including wheels and handles. Carriers measure what sticks out.
Measure across the bag at its widest point, with the pockets closed.
Measure the depth, including any expansion zip opened as you travel.
Add the length, width, and height. That total is the linear inches.
Subtract the carrier's limit from the total. A positive number means an oversize charge is likely.
A bag measuring 28 by 12 by 10 inches is 50 linear inches against a 62-inch limit, so it is within the limit with nothing over.
Use your own source and details. The example is not a record about a real person or organization.
