How Airlines Calculate Luggage Size

Airline baggage limits in inches are based on the outer box dimensions of your bag, not volume.

Carry-on rule (most common): single-side limits such as 22 x 14 x 9 in (L x W x H).
What must be included: wheels, handles, feet, and any rigid external parts.
What is not used as the main rule: liters/cubic volume is usually not the acceptance criterion.
Sizer logic at airport: if the bag does not fit the frame, it can be denied or gate-checked.
