Capacity
The total volume of the suitcase in liters. On the one hand, the number of things that can be placed inside depends on this parameter, and on the other hand, the dimensions and weight of the suitcase itself. The optimal balance between these characteristics depends on the number of people for which the product is designed, as well as on the characteristics of the planned trips.
Conventionally, suitcases can be divided into 3 categories:
small(up to 30 L),
medium(up to 70 L),
large(up to 100 L) and
huge(over 100 L). The first option is well suited for those who are going to travel alone, and the duration of trips is not very long. Also in this category are
children's suitcases, which are distinguished by a catchy design, compact size and special appearance. Medium models are suitable for two people (or, again, for one — with a long journey). And the largest suitcases can be called "family".
Also note that some models may have adjustable dimensions and, accordingly, adjust to the volume; for such suitcases, the maximum volume is indicated in the characteristics — in a fully unfolded state.
Dimensions (HxWxD)
Dimensions of the suitcase in height, width and depth (it is assumed that the product stands vertically on wheels). For products with volume adjustment, the unfolded dimensions are usually indicated.
It is worth noting that with the same volume, different models may have different sizes; knowing these numbers, you can to some extent evaluate the features of the suitcase and choose the necessary
model of hand luggage on the plane. For example, a large width provides stability when transported on wheels, but is not very convenient when transported on a train — the suitcase may not “fit” under the shelf on the side; wide bags (see "Type") are also less convenient to carry by the handle on the front side, etc.
Weight
The weight of the empty suitcase. The lower this value, the easier it will be to transport luggage (with the same weight of things placed inside). On the other hand,
lightweight suitcases usually have a less dense body material. Therefore, it is worth choosing a model by weight, taking into account what balance between strength and lightness will be optimal for you.
Number of external pockets
The presence of pockets in the suitcase allows you to sort small things so as not to search all over the suitcase. External pockets allow you to provide quick access to them. Among those, there can be both small ones for keys, passports, and larger ones where you can put documents, change of clothes.
Number of internal pockets
Internal pockets allow you to sort small things from the general luggage. Mostly made with mesh, which additionally allows you to see what is in your pocket and quickly get access to the necessary "little things".
