Cabin bags, measured.

Airlines publish a box. Your bag either fits it or it doesn't. Cabin Sized is about that box — what each airline actually allows, how it's enforced at the gate, and how to pack for it.

What's coming

Cabin and underseat dimensions by airline, kept current. Plain guides to packing into a fixed volume. Nothing here is sponsored by an airline.

This site is new and its guides are still being written.
