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.

Measure length, width, and height on the outside—include wheels and handles.

Compare each side to this airline's limit (not only total volume).

If you are close to the limit, lighten the bag and keep essentials in your personal item in case of a gate check.
