A little preparation. A calmer departure.

Make room for the trip.

Measure your packed bag. Bring your airline’s allowance. See how the numbers compare before you leave home.

01 / Compare

Your bag, your allowance

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.

Changing units clears the measurements; it does not convert them. Enter numbers above 0 and at most 1,000, with up to two decimal places.
