The total volume of the bag, usually, includes all regular pockets (including external ones).
A large volume allows you to put a lot of things inside, but it significantly affects the dimensions, weight and price of the product itself. Therefore, when choosing, you need to strike a balance between capacity and convenience.
It is believed that a volume of
25 – 35 liters will be quite enough for the things one person needs for a trip lasting 3 – 4 days. More detailed recommendations can be found in special sources.
At the same time, we note that even with numerous things, a large bag is not always the best option. In some cases (for example, if several people are traveling), it is more convenient to buy several products of a relatively small volume and divide the luggage between travelers.
Now on the market there are such volumes of bags:
small - up to 50 liters,
medium - from 51 to 75 liters,
large - from 76 to 100 liters and
huge, whose volumes exceed 100 liters. At the same time, you should not forget that there are also
travel bags for hand luggage, as well as an even smaller version
of hand luggage for low-cost airlines.
