How to choose the right backpack size

0 комментариев


In order to fully appreciate the convenience and functionality of a backpack, you need to choose the right size for it. Buying too large or, conversely, too small a model will cause the load to be distributed incorrectly, causing discomfort and pain. In this case, instead of the pleasure of a useful acquisition, the buyer will receive completely opposite emotions. Let us dwell in more detail on how to choose a backpack in size for a student and an adult, what to focus on.

For a child

The spine in children is still developing, posture is being formed, and parents should avoid everything that can negatively affect these processes. For students in grades 1-4, small-sized satchels are suitable, in accordance with the still small stature of children. Older students need more spacious backpacks because the number of subjects studied and, consequently, textbooks grows as they grow older.

In the upper grades, the volume of textbooks and notes reaches a critical mass, but this is no longer so important, because boys and girls aged 16-18 already have the complexion of adults. One way or another, regardless of age and height, backpacks should have a reinforced back and strong wide straps.

We offer parents of preschoolers and students of primary and secondary grades to use the table of the ratio of the height of the child and the length of the back of the product when choosing a backpack.

And this table will help to correlate the age, height and weight of the child (boy and girl) with the height of the back of the backpack and its weight in an empty and full state.

For an adult

A common situation: the buyer tries to choose a larger backpack, even if they themselves cannot boast of being tall. The motive is simple — the larger the product, the more spacious; while many do not even think about how to choose a backpack for height. The wrong choice very soon leads to back pain and a host of other inconveniences.

The main rule in this case is that the dimensions of the backpack must correspond to the physical parameters of the user. Then it will be organic to look at the thing on its owner. Such physical data include height, weight, back length, hip circumference. This issue has been comprehensively studied by professionals, who have developed the following recommendations:

  • back length over 51 cm and hip circumference over 84 cm corresponds to size L;
  • body length 45-52 cm and hip circumference 75-85 cm corresponds to size M;
  • body length less than 45 cm and hip circumference 75 cm corresponds to size S;
  • those whose parameters are less than S or greater than L should choose XS or XL, respectively.

How to take measurements correctly

The length of the backpack, as mentioned above, is selected in accordance with the length of the back. A sales assistant will help you measure it in the store, who will do this with a centimeter tape or use a special device. The segment, called the length of the back, is located between the seventh cervical vertebra and the waist. When measuring, you should not pull the centimeter, but rather, let it hang down smoothly, repeating the curves of the spine.

Next, you need to measure the circumference of the hips, according to which the size of the waist belt is selected. The right choice is a guarantee that the belt fits perfectly on the hips and takes on more than half the weight of the load. In the tightened position, the harnesses should comfortably (sufficiently tightly) wrap around the hips. At the same time, approximately 10-12 cm should remain between the free ends, in a tightened state.

With the above recommendations, it becomes easy to calculate the size of a backpack. In fact, there are always nuances in this matter. Some products, while seeming compact, are actually very roomy. Therefore, the purchase should be preceded by a comprehensive inspection of the product.

In offline stores, you can always contact the seller, who will help you make measurements and advise on the features. If it is not possible to visit the store, or you have to buy online, it is better to ask someone close to measure the length of the back in advance, because it is not easy to do it yourself. For these purposes, you will need a tailor’s meter, which can be found in every home.

What is the difference between men’s and women’s backpacks?

Considering the question of how to choose the size of a backpack, one cannot ignore such a moment as the differences between male and female models. Many users are convinced that there is no fundamental difference between them. In a sense, this is true, if we take into account only the unisex style models that are in demand among urban youth. However, the difference is inherent in sports and tourist models, and it is due to the following factors. Men have different body proportions than women. In particular, with the same height, the length of the back of the representatives of the stronger sex is greater. Therefore, backpacks used for long-term loads should also differ in size.

A female figure with a thinner waist than men and wide hips requires special models of backpacks. But there is also a chest, and narrower shoulders that need straps of a different configuration. All these points are taken into account by equipment manufacturers who produce products in full accordance with the «gender» purpose.

Summing up what has been said, I would like to note once again that it is always necessary to choose a backpack in size, regardless of who it is intended for. Posture, health and well-being depend on the correct choice.
