Luggage comes in many sizes, and there are specific guidelines for using them.

Common carry-on suitcase sizes:
Sizes 20 inches and smaller are permitted on airplanes (international boarding dimensions must be within 115 cm), making them ideal for a solo trip lasting around four days.

A 20-inch suitcase is suitable for a single traveler on a trip lasting around 7 days. A 20-inch rolling suitcase refers to one whose sum of length, width, and height does not exceed 115 cm; such carry-on luggage is permitted in the aircraft cabin. The most common dimensions for a 20-inch rolling suitcase are 34×50×20 cm, making it look compact and elegant.

The 22-inch item must be checked in and is suitable for a single traveler going on a trip lasting around 7 to 10 days.

A 24-inch suitcase must be checked in and is ideal for a trip of about 7 days with two people. A 24-inch rolling suitcase refers to a suitcase whose sum of length, width, and height does not exceed 135 cm—this is the standard size for carry-on rolling suitcases as stipulated by airlines. The most common dimensions for a 24-inch rolling suitcase are 60 cm in length, 38 cm in width, and 28 cm in thickness. This is the most widely used size because it offers a moderate volume that can hold an appropriate amount of items—neither too much nor too little. The 24-inch rolling suitcase is the most common type and also the most suitable for general travelers.

The 26-inch item must be checked in and is suitable for a two-person trip lasting about half a month.

A 28-inch suitcase must be checked in and is ideal for families traveling together or for shoppers heading to Hong Kong. A 28-inch rolling suitcase refers to a suitcase whose sum of length, width, and height does not exceed 158 cm—this is the standard airline-approved size for 28-inch carry-on rolling suitcases. The most common dimensions for a 28-inch rolling suitcase are 70 cm in length, 48 cm in width, and 30 cm in thickness. This is a relatively large-capacity suitcase, perfect for professionals who travel frequently for business.

The 32-inch suitcase must be checked in, just like the 28-inch one—but this applies only to domestic flights and certain Southeast Asian airlines. If you’re going on a self-driving tour, however, the 32-inch suitcase offers unparalleled capacity.
