Kids Ski Binding DIN Chart (ISO 11088:2023)
Official Junior Skier Code reference matrix for children and youth skiers weighing 10 kg to 48 kg (22 lbs to 107 lbs), with age modifiers, growth check intervals, and rental standards.
Children's ski bindings require much lower release torque settings than adults because young bones and developing growth plates (epiphyseal plates) have lower torsional strength. Under ISO 11088:2023, all children aged under 10 receive an automatic 1-row upward step (lowering their DIN setting by approximately 0.5 to 1.0). Never set a child's DIN by guessing, adult charts, or without measuring boot sole length in millimeters.
Junior Skier Code Release Matrix (Codes A to H)
The table below extracts ISO 11088:2023 Table 2 rows for children up to 48 kg. Trace weight row across to the boot sole length (BSL) stamped in millimeters on the heel of your child's boot.
| Code | Child Weight (kg) | Child Weight (lbs) | BSL < 250 mm | BSL 251–270 mm | BSL 271–290 mm |
|---|---|---|---|---|---|
| Code A | 10–13 kg | 22–29 lbs | 0.75 | — | — |
| Code B | 14–17 kg | 30–38 lbs | 1.00 | — | — |
| Code C | 18–21 kg | 39–47 lbs | 1.50 | 1.25 | — |
| Code D | 22–25 kg | 48–56 lbs | 2.00 | 1.75 | — |
| Code E | 26–30 kg | 57–66 lbs | 2.50 | 2.25 | — |
| Code F | 31–35 kg | 67–78 lbs | 3.00 | 2.75 | 2.25 |
| Code G | 36–41 kg | 79–91 lbs | 3.50 | 3.00 | 2.75 |
| Code H | 42–48 kg | 92–107 lbs | 4.50 | 4.00 | 3.50 |
Note: If the child is under age 10, shift up one row in the table (e.g. Code D shifts to Code C) unless overridden by a professional ski technician.
The 3 Critical Rules for Children's Ski Bindings
Young children have more flexible joint capsules but softer, developing bone structure. ISO 11088 mandates shifting 1 code row upward, reducing release torque to prevent spiral tibia fractures.
Kids boots use ISO 5355 Type C (Children) soles with smaller lug dimensions. Junior bindings are engineered exclusively for Type C soles. Never force Type C boots into adult bindings.
Children can grow an entire boot size and gain 10+ lbs over a single winter. A larger boot sole length decreases release torque, while weight gain increases it. Re-check bindings every 30 skiing days.
Rental Bindings (ISO 13993) vs Personal Gear (ISO 11088)
When you rent skis for your children, reputable rental shops calibrate bindings according to ISO 13993 (Rental shop operational standard for alpine ski-binding-boot systems). Rental bindings feature quick-adjust track systems for toe and heel pieces. Always confirm the rental technician:
- Weighed and measured your child on an in-shop scale (do not guess).
- Checked forward pressure indicator pins on the rental track.
- Tested release value on a mechanical torque inspection machine (ASTM F1063 sample testing).
