Choosing the right size backpack for a schoolchild is an important process that affects the child’s comfort and health. Here are some tips on how to choose the right backpack:

  1. Size: The backpack should match the child’s height. Ideally, it should be about 2/3 of the child’s height and not exceed the waist level.
  2. Weight: Try to choose a lightweight backpack. The maximum weight of a backpack filled with textbooks should not exceed 10-15% of the child’s weight.
  3. Adjustable straps: The straps should be wide and soft, and also adjustable in length so that the backpack sits comfortably on the shoulders.
  4. Back support: Pay attention to the presence of an anatomical back and orthopedic inserts that will help distribute the load and maintain posture.
  5. Compartments and pockets: A backpack with several compartments will help organize things and make them easier to access.
  6. Material: Choose water-repellent and durable materials that are easy to clean.
  7. Design: Consider your child's preferences so that he or she wants to wear the backpack and feels comfortable in it.
  8. Safety: The backpack should have reflective elements to increase visibility in the dark.

Following these recommendations will help you choose a backpack that will be comfortable and safe for your child.
