Dimensions and introduction of luggage

With the popularity of air travel, early suitcases were made of wood or other heavy materials.

The material of luggage tends to be light hard plastic or cloth. Most models are also equipped with built-in wheels, which can be easily pulled by a pull rod. After 20 10 years, there are also four-wheeled suitcases, which can not only rotate 360 degrees, but also be easily pushed on the flat ground.

In addition, luggage can also be divided into hard-shell luggage and soft-shell luggage according to the shell.

Hard-shell suitcases are more resistant to falling and suitable for suitcases that need more protection. Soft-shell luggage is usually lighter and more flexible than hard-shell luggage. However, the zipper position of soft-shell suitcase is easy to burst because there are too many objects inside.

The size of luggage in the market is generally based on the regulations of the International Air Transport Association airlines on the size of carry-on luggage and checked luggage.

For example, Cathay Pacific stipulates that the maximum size of each checked baggage must be less than 158 cm, and the maximum size of each hand baggage must be less than 56x36x23 cm.
