Luggage Size Checker

Most major international airlines allow carry-on bags up to 55 by 35 by 25 centimeters, including wheels and handles. Budget airlines often have stricter limits — Ryanair's basic fare carry-on is limited to 40 by 25 by 20 centimeters. Always check your specific airline and fare class as dimensions vary significantly.

If your bag exceeds the size limit at the gate, most airlines will gate-check it for a fee that is typically higher than pre-paying for checked luggage. Budget carriers are especially strict and may charge significant fees at the gate. If your bag is only marginally over the limit, removing outer items and wearing bulky clothing can help.

Pack light using a carry-on-sized bag, wear your heaviest clothing items during the flight, use packing cubes to compress volume, and research your airline's personal item policy as many carriers allow a smaller second bag for free. Choose airlines like Southwest that include free checked bags in the ticket price.
