28 - 32 Suitcase These are very large suitcases meant for trips exceeding a week. They have a tremendous capacity for anything you would like to travel with. Due to their large size, when fully packed they can be difficult to maneuver and may exceed the 50 lbs. weight restrictions that most U.S. airlines enforce.

A 28-inch suitcase is considered a "Large" or "Large Checked" bag in 2026 and is generally the maximum size recommended for standard international travel. It typically offers a capacity of 90 to 110 liters, which is enough space to hold clothing and gear for a trip lasting 10 to 14 days, or even longer if you pack efficiently. Because of its sheer volume, it is very easy to exceed the standard airline weight limit of 50 lbs (23 kg) when using a 28-inch bag; even if the bag isn't physically "full," heavy items like shoes and denim can quickly trigger overweight baggage fees. Furthermore, a suitcase of this size can be cumbersome to navigate through narrow European train aisles or small Japanese hotel rooms. Most 28-inch bags stand about 30 inches tall when including the wheels, meaning they will not fit in any overhead bin and must always be checked. If you are a solo traveler or moving between multiple locations, you might find this size difficult to manage on public transport, but for family holidays or long-term relocations, it is the industry standard for maximum capacity.
