Ergonomic school backpack: weight, size and checklist (parents and students)

1) The most important rule: backpack + contents up to 10% of body weight

The SNS24 (Health 24) warns that carrying backpacks with excessive weight (more than 10% of body weight) can have negative impacts on health.
The DGE also recommends that the backpack and its contents should not exceed 10% of body weight (e.g., 25 kg → 2.5 kg).

Because this matters (in practice):
It's not "drama." It's prevention: less tension in the shoulders, neck, and lower back, especially in growing children.


2) How to choose an ergonomic school backpack (what you should check in the store)

The DGE recommends that the backpack be properly positioned on the shoulders and that the straps be adjusted to sit above the hips .

Look for these characteristics:

  • wide, padded straps

  • padded back (ideally breathable)

  • Easy adjustment capability (so the backpack doesn't "hit" your back)

  • durable fabric (because it goes all the way to the floor… many times)

Bonus (very useful):

  • chest strap (helps to stabilize)

  • Reflective elements (for winter and early morning outings)


3) Right size: the backpack should fit the child (not the other way around).

A common mistake is buying a backpack "to last for years," and then the backpack ends up being too big.
Ideally:

  • do not exceed the width of the back by much.

  • Don't go down too low (the lower and further from the body, the more it "pulls").


4) How to adjust it correctly (this is invaluable)

DGE advises:

  • backpack properly positioned on the shoulders

  • Adjustable straps to sit above the hips.

Simple rules:

  1. Adjust the two identical straps.

  2. The backpack should rest against your back (not be "hanging").

  3. If there's a chest strap, use it when you're carrying a heavier load.

Yes, wearing it on both shoulders is essential (it prevents compensation).


5) How to pack your backpack to reduce strain (even with the same weight)

DGE recommends placing the heaviest items closest to your back .

"Smart" tidying up:

  • large books/notebooks behind

  • pencil case and lighter items in front.

  • bottle in side pocket (securely fastened)


6) Tips for reducing actual weight (what parents can control)

SNS24 recommends paying attention to weight and the impact of excessive load.

Simple measures:

  • Check your backpack every week (remove accumulated "stuff").

  • Use lighter files/notebooks whenever possible.

  • avoid carrying “everything every day” unnecessarily


7) Wheeled backpack (school trolley): when does it make sense?

It can help on long, flat routes, but it's not always ideal (stairs, uneven sidewalks, schools without elevators).
If you choose a trolley, confirm that the student can maneuver it without straining their shoulder/wrist and keep the weight within a reasonable range.

  • Total weight ≤ 10% of body weight
