"A backpack that doesn't fit well or is used incorrectly may cause back and shoulder tension or pain." When buying a backpack and where to buy backpacks, consider the appropriate size and comfort rather than price. Generally, the best school backpacks for teens may not be the most fashionable or the most expensive. "
To find a backpack with the proper fit, here we offers the following tips:
1. Choose the right size: the width of the backpack should be commensurate with the width of the person. For example, children should not choose adult-sized backpacks. In addition, the height of the backpack should extend from about two inches below the shoulder blades to waist level, or slightly higher than the waist.
2. Choose wide shoulder straps and padded shoulder straps, which can provide more comfort and protect your shoulders from excessive pressure. It is very important to use both shoulder straps to evenly distribute the weight of the backpack. Using only one shoulder strap will put extra pressure on the shoulders. Adjustable shoulder straps are useful, not just for a proper fit, but also for a proper position-again, the backpack should sit slightly above the waist and the length of the two shoulder straps should be the same.
3. Choose a backpack with pockets, slots and partitions to distribute the weight evenly: In addition to using two shoulder straps to ensure that the backpack is placed at the correct height, consider a backpack with pockets, slots and partitions to help evenly distribute the extra weight. Heavier items should be placed close to the person's back, in a backpack. Lighter objects can be placed far away from the body.
4. Keep the weight of the backpack at 15% of the child's weight. It is important not to increase the weight of the backpack. This is especially true when considering children. The total weight of the backpack and its contents should not exceed 15% of a person's weight.
