Ergobag Size Chart
Ergobag school backpacks are adjusted to the child's body height. The Your-Size-System grows with the child on the classic models, while cubo light uses a lighter Hugging system without height adjustment.
Body Height and Carrying System
| Model range | Body height / adjustment | Carrying system | Note |
|---|---|---|---|
| flex / pack / cubo / prime | approx. 100–150 cm | Your-Size-System | height-adjustable to the child |
| maxi | approx. 120–170 cm | Your-Size-System | for taller children; 24 L main compartment |
| cubo light | no fixed height scale | Hugging Carrying System | especially light; suited to smaller/petite children |
Loaded weight: Ergobag recommends that a filled school backpack weigh no more than approximately 15% of the child's body weight.

Correct Adjustment
- Open the back panel and set the Your-Size-System to the child's height.
- Close and tighten the hip belt over the pelvis.
- Adjust shoulder straps so the bag sits close to the body.
- Fasten the chest strap at a comfortable height; Ergobag also provides width adjustment.
Safety notice: Do not cover reflective or fluorescent areas. Avoid unnecessary overloading and readjust the backpack regularly as the child grows.
