The American Academy of Orthopedic Surgeons recommends that the weight of a backpack should be less than 10-15 percent of a child’s body weight, but that isn’t always the case. Too often, children don’t wear their packs correctly, increasing risk of injury. Improperly used backpacks may injure muscles and joints and can lead to severe back, neck, and shoulder pain, as well as posture problems.
