Frequently asked questions
How do I know if my bag fits an airline?+
Measure your bag’s height, width and depth including wheels and handles, then enter them above. We compare against every airline’s sizer-box limit and show whether it fits, is tight, or is over — with the exact margin in cm and inches.
Do you include wheels and handles in the measurements?+
Yes. Airlines measure the widest points, so you should too. Our bag catalogue also uses external dimensions including wheels and handles.
Is the data official?+
We compile limits from airlines’ public baggage pages and show a “last verified” date and a link to each official policy. Rules change, so always confirm with the airline before you fly. See our methodology for the full detail.
