Make room for the trip.
Measure your packed bag. Bring your airline’s allowance. See how the numbers compare before you leave home.
Use the same unit for all six dimensions. Enter the three outside measurements in any order. We pair longest with longest, middle with middle, and shortest with shortest: rotation is allowed, squeezing or diagonal fitting is not.
This checks dimensions only. It does not check weight, fare entitlement, bag count, sizer shape or available cabin space. A dimensional match is not permission to board with the bag; it may still need to be checked.
| Side | Bag | Allowance | Difference |
|---|
Zero difference means exactly at the entered limit. Re-measure a close fit and check the carrier’s current requirements. Positive difference is room remaining; negative difference is an excess.
