Add outside length, width and height in inches, including wheels, handles and protruding parts. For example, 28 + 18 + 12 equals 58 linear inches.
Why the answer can change
A suitcase marketed as a 28-inch bag is not automatically within a 62-inch total. Check every side and the carrier’s own maximum.
Check your own trip
- Start with the airline flying each leg, the fare you bought, and the dates on your ticket.
- Count bags for each traveler. Measure the packed outside of every bag, then find both the standard limit and the largest bag the airline will accept.
- Look up the bag fee, extra-piece fee, and any weight or size charge separately. If one amount is missing, you don’t have a complete total yet.
- Check the final price in the airline’s booking or check-in flow, and save the receipt.
Before you pay
Use the size and fee tools to put your bag details in one place. If we can’t confirm the full cost, they’ll tell you what still needs an airline quote.
Where this gets tricky
A 30-inch suitcase can be under or over 62 linear inches depending on its width and depth. Wheels and handles may add to the outside footprint.
Here’s what to check: Use three outside measurements, not product marketing size. If the sum exceeds the airline’s ordinary limit, check its separate acceptance maximum.

The listed charges add up to 45 USD in this example. Your checkout may differ. Online standard bag fee plus the applicable excess assessed under the published table; not a promise that excess can be prepaid.
