Back to School Backpack Safety: A Guide for Markham Families
Back to school backpack safety is worth a few minutes of attention every September, since an overloaded or poorly worn backpack can contribute to neck, shoulder, and back discomfort in growing kids. Here’s what Markham parents should know about choosing and wearing a backpack the right way.

Why back to school backpack safety matters
Kids carry backpacks for years of their growing lives, often loaded with textbooks, laptops, and gym gear. When a backpack is too heavy or worn incorrectly, it can pull the shoulders forward, round the upper back, and shift a child’s center of gravity, which may contribute to neck and shoulder discomfort or fatigue over the school year.
This doesn’t mean every backpack causes a problem, but it’s worth paying attention to weight and fit, especially for kids who are still growing.
Many parents also find it helpful to do a quick weekly check of what’s actually inside the backpack. It’s easy for extra binders, forgotten library books, or a second pair of shoes to add up without anyone noticing. A five-minute check-in on a Sunday evening, paired with a habit of using a locker for textbooks that aren’t needed every day, can meaningfully cut down on the weight your child carries through the halls.
When to see a doctor first
If your child reports numbness or tingling in their arms or hands, persistent pain that doesn’t improve with rest, or visible changes in posture that concern you, it’s best to have them assessed by a physician before anything else.
Choosing and wearing a backpack correctly
The Canadian Paediatric Society recommends keeping a packed backpack at roughly 10 to 15 percent of a child’s body weight. A few other tips that help:
- Choose a backpack with wide, padded shoulder straps and a padded back panel.
- Use both shoulder straps rather than slinging the bag over one shoulder.
- Adjust the straps so the backpack sits close to the body, roughly at waist height, not sagging low.
- Pack heavier items closest to the back and use a hip or chest strap if the backpack has one.
- Encourage your child to only carry what they need for the day, and use a locker or cubby for the rest.

How a chiropractor can help
If your child is experiencing ongoing neck, shoulder, or back discomfort, a chiropractic assessment can help identify whether posture, muscle tension, or joint restriction may be contributing factors, and whether care may be appropriate alongside changes to their backpack habits.
Frequently asked questions
How heavy is too heavy for a school backpack?
A commonly cited guideline from the Canadian Paediatric Society is to keep a packed backpack at around 10 to 15 percent of a child’s body weight. If a backpack regularly exceeds that, it’s worth reviewing what’s being carried daily.
Can a heavy backpack cause long-term problems?
There isn’t strong evidence that backpacks alone cause long-term spinal problems, but persistent discomfort is worth paying attention to, and good habits around weight and fit are a reasonable precaution during the growing years.
Should my child use a rolling backpack instead?
Rolling backpacks can reduce the load carried on the shoulders and back, but they aren’t practical on stairs or in crowded hallways. The right choice depends on your child’s school environment and daily routine.
When should I bring my child in for a chiropractic assessment?
If your child has ongoing neck, shoulder, or back discomfort that doesn’t improve with rest, adjusting their backpack habits, or over-the-counter comfort measures, an assessment can help identify what might be contributing.
