Backpacks are a daily school essential, but when poorly designed or too heavy, they can harm a child’s posture and spine. A backpack should weigh no more than 10–15% of the child’s body weight. Regularly checking this at home can help parents prevent excess strain. Ill-fitted or oversized bags make children lean forward to balance the load, increasing the risk of long-term neck, shoulder and back pain. Choosing a backpack proportional to the child’s torso, with padded shoulder straps and, if needed, a waist strap, improves comfort and support. Avoiding cross-body bags is also important, as they create uneven stress on one side of the body. Organizing the bag so heavier items sit low and close to the spine reduces strain further. Finally, engaging children in conversations about comfort, posture and preferences ensures they understand the importance of wearing their backpacks correctly—and are willing to cooperate.
Backpacks are a school essential. Every kid carries a backpack to school, 5 days a week. This innocent accessory however, has the potential to be a health hazard for kids. When ill-fitted, a backpack might as well be a brick to the spine. Heavy backpacks can ruin your child’s posture and give them long-term neck, shoulder and back pain. For smaller children, heavy backpacks can throw them off balance and lead to falls. Choosing your child’s backpack carefully, and ensuring they wear it correctly can help prevent unnecessary back injuries. In this article, we will delve into all the things to keep in mind when buying your child’s backpack, and how to wear it correctly.
According to Paediatricians, A child’s backpack should be proportionate to their size. A 6-year-old cannot carry a backpack sized for a 16-year-old. In general, experts recommend that children’s backpacks should weigh no more than 10-15% of the child’s body weight. So, if your child is 25 kgs, their backpack should only be around 3kgs. You can easily verify this by conducting a small experiment at home, with a weighing scale.
Take your child’s backpack, filled with books and stationery for an average school day, and put it on their back. Weigh your child with their backpack on. Now weigh your child again, without their backpack. The difference between the 2 weights is the weight of the backpack. Divide your child’s weight by 10 – Their backpack should ideally weigh around this much. If the backpack is heavier, investigate what they have in their backpack. Are they carrying unnecessary books to school every day? Is the backpack itself too heavy for them? Speak to the child’s teachers and other parents from their school to see how this burden can be reduced.
Overly heavy backpacks strain your child’s neck and back. You may have noticed your child curving their spine and leaning forward when they put their heavy backpack on. They are trying to compensate for the heavy weight, but this posture will cause long-term back problems. To reduce this risk, it is important to choose the correct size of backpack for your child. Parents are often tempted to buy a big backpack so their child can fit more things in it, but this is a bad idea.
Choose a backpack that is no wider than your child’s torso – The backpack should be smaller than your child’s torso when worn. The bottom of the backpack should be above, or at your child’s waist line, and not lower. A backpack that hangs below the child’s waist will pull them backwards when they walk, and they will be forced to lean forward to compensate. When buying a backpack, tighten the straps fully and have your child try it on. Then ask them to sit on a bench. While sitting, the backpack shouldn’t touch the seat – If it does, it’s too big.
The backpack should be strapped to your child’s torso securely. If it swings around too much when they walk, they could get hurt from the weight repeatedly hitting their back. If your child’s backpack is already on the heavier side, it’s a good idea to consider getting them a backpack with a waist strap that secures the backpack to their torso and stops it from swinging around. Make sure your child actually uses the waist strap. It may not be “cool”, but neither is having back pain at 14. Another feature to look for in a good backpack is padded shoulder straps. Thick, cushioned shoulder straps distribute the weight evenly across the shoulders and don’t dig into the shoulders causing red marks. Straps that dig into the shoulder can also reduce blood circulation to the arms, causing tingling and numbness in the hands.
Cross-body bags are not ergonomic for your kids. The single strap puts a lot of stress on one shoulder at a time. Your child will always be off balance as they lean to one side while wearing the bag. They will also be forced to keep switching sides because of the uneven load digging. The cross-body bag also tends to swing around a lot and will keep hitting them in the side.
The way items are organized in the bag can also affect the impact on your child’s back. Choose a bag that has multiple compartments so the items inside can be organized and held in place. The items in the bag shouldn’t roll around too much, even if your child runs with the backpack on. Teach your child to pack their bag in such a way that the heaviest books are placed low, and towards the centre of the bag. Avoid overstuffing the bag too. When full, the things in the bag shouldn’t be poking into your child’s back.
Have an open conversation with your child to first find out how their back feels. Discuss their posture with them, and explain how bad posture now could impact them in the future. The interventions you make vis-a-vis your child’s backpack have to be done in consultation with your child. You need to secure their full co-operation so that these measures are actually effective. It makes no sense to buy your child a backpack that they hate. If fashion is a concern, and your child thinks their ergonomic backpack is ugly, do not invalidate their opinion. Find a compromise that works for everyone. Maybe you can plan a bag decorating activity, and let your kid put fun stickers on their school backpack.
