Please tell me what size of suitcases you should bring when traveling abroad for shopping.

1. "18-inch": the size that can be taken on an airplane, suitable for one person traveling for about 2-3 days

2. "20-inch": the size that can be taken on an airplane , suitable for one person traveling for about 5 days, business trip or short trip. Generally, the sum of the length, width and height of a 20-inch trolley case shall not be greater than 115cm. This type of carry-on suitcase can be brought into the aircraft cabin. The most common size design of a 20-inch trolley case is 30 cm long × 20 cm wide × 55 cm high. This type of trolley case looks small and exquisite, and is the first choice of many young consumers and business people. Because they usually don’t carry a lot of luggage, just some simple daily necessities, so a trolley suitcase of this size is perfect for them.

3. "22-inch": must be checked, suitable for one person to travel for about 5-7 days, not much different from 20-inch.

4. "24-inch": must be checked, suitable for 2 people traveling for about 7-10 days, and domestic travel. Generally, the sum of the length, width and height of a 24-inch trolley case shall not be greater than 135cm, which is the standard boarding trolley case size stipulated by the aircraft. The most common size design of the 24-inch trolley case is 38cm long x 28cm wide x 60cm high. It is the most commonly used trolley case. It is medium in size and can hold the right amount of items, not too much and not too little. The 24-inch trolley case is the most common trolley case, and it is also the most suitable trolley case for public use. If you are a college student or a white-collar worker, I believe this trolley case can meet your travel requirements.

5. "26-inch": Must be checked in, suitable for 2 people traveling for about 10-15 days, no shopping required when traveling overseas.

6. "28-inch": must be checked in, suitable for family travel for about 15 days, shopping in Hong Kong, studying abroad, etc. A 28-inch trolley case means that the sum of the length, width and height of the trolley case shall not be greater than 158cm. This is the standard aviation trolley case size for a 28-inch boarding trolley case. The most common size design of the 28-inch trolley case is 70 cm long × 48 cm wide × 30 cm thick. It is a relatively large-capacity trolley case. This kind of trolley case is suitable for people who are on the go for business all year round. The large 28-inch capacity can accommodate many daily and work supplies for them, making it very suitable for the needs of business people who are on the go all year round.
