Study guide




A standard backpack for students should be the right size and weight for the student; Otherwise, it will be non-standard, and since the student is growing up, carrying this non-standard backpack on a daily basis can Irreparable effects For him to follow. In this article, we will tell you about the specifications and criteria that a standard backpack should have.

What are the criteria for a standard backpack for students?

Preservation Health Students and Comfort They are two important factors when carrying a backpack that demonstrate the need for a backpack to be standard. Most parents are concerned about the weight of their child’s backpack and are always looking to buy a suitable, standard backpack. Let’s learn more about the criteria for a standard backpack.

Two important features of a standard backpack for students

1. Backpack weight

Experts’ general guidelines are that children should not carry more than 15% of their body weight. In other words, this amount is equivalent to 3.5 to 5 kg for an elementary school student. Heavy backpacks that weigh more than 30% of a student’s body weight can have adverse effects on the child. Constant carrying of a heavy backpack can lead to poor posture and poor walking habits. These conditions can gradually increase the risk of neck and back pain in the child.

2. School bag style

School bags are divided into two general categories:

  • Double-walled bags;
  • Single-walled bags (douche bags).

In terms of the student’s ability to carry the weight of the school bag and get used to it, these two modes are considered standard and do not cause any harm to the body:

  • Up to 20% of body weight in backpacks (carrying a school bag with both shoulders);
  • Up to 10% of body weight in shoulder bags (carrying a school bag with one shoulder).

Load bearing more than the recommended amount on one shoulder exerts unbalanced forces on the spine and body of a growing child. Carrying the entire weight of a backpack on one shoulder can cause pressure on the spine and muscle pain.

The double backpack is designed to spread weight on both shoulders. However, when the child tries to lift the backpack and place both straps on the shoulder, this often leads to spinal torsion. Constantly loading and unloading the backpack can also cause muscle fatigue and strain, especially when the backpack is heavy.

The weight and style of the backpack are the two determinants of its standard. Make carrying a backpack a light experience for your child by choosing a lightweight backpack that fits your child’s needs.

9 important elements in designing a standard backpack for students

A standard backpack is designed for students based on several factors. If the backpack you are considering does not have any of these features, it is not considered standard:

1. Fit the length of the trunk

The backpack should be located between the C7 vertebrae (the first and most prominent bone in the spine when the neck is bent forward) and the top of the pelvis (iliac crest). Put your hands on your hips and your thumbs on your waist. The place where the thumbs are located is where the end of the backpack should be. If the backpack is taller than the trunk, the ergonomic fit of the body will be disturbed. The length of your child’s torso indicates that he or she needs a small backpack, either medium or large.

2. Have wide straps

Backpack straps are one of the most important parts of it. If these straps are narrow, they will cause pain to the student’s shoulder and make it difficult for him to carry the load.

3. Have a strap on the chest

The strap on the chest holds the shoulder straps in place.

4. Instead of just one compartment, have several compartments inside

Enclosures help organize the contents of the backpack. The presence of separate spaces ensures that the student’s belongings are regularly placed in the backpack.

5. Have side or top pockets

It is very useful to have pockets next to or on the backpack that are equipped with magnetic attractions. These pockets are a place for bottles, pencils or any other device.

6. Have a waistband

If the backpack is heavy, the waistband distributes the load on the hip joint and reduces pressure on the shoulders and neck.

7. The support has special pads

Having a suitable support or backrest in the backpack makes it easy to carry.

8. Be waterproof

Waterproof the backpack is very useful to prevent items from being damaged by rain or back sweat.

9. Have compressed straps

The use of compressed straps will make the backpack compact and easier to carry.

Important elements in designing a standard backpack for students

Most of the bags that are advertised as standard and ergonomic backpacks have some of the mentioned features. Keep in mind that the more features the bag has, the heavier it will be.

Your child should put the strap of this bag on his chest. In addition, it should be carried in such a way that it does not hang and is completely close to its body.

If your child is interested in a backpack and is able to use the backpack easily, you can provide him / her with his / her favorite backpack if you follow the above criteria.
