🎿 Ski Binding DIN Calculator
Generate a reference DIN setting by combining weight, height, age, skier type, and boot sole length. Always have settings verified by a certified ski technician.
Under 10 or over 50 reduces DIN for safer release.
Stamped on boot heel (e.g., 305 mm).
Type I - slower speeds / beginners. Type II - recreational. Type III - high speeds / aggressive skiing.
Recommended DIN
5.0
Skier code 7 • BSL bucket 291 – 310 mm
Conservative option
4.0 DIN
Reduce one skier code (more likely to release)
Aggressive option
6.0 DIN
Increase one skier code (harder to release)
| Input | Value |

| Height | 1148 in (452 cm) |
| Boot sole length | 305 mm (291 – 310 mm) |
| Adjustments | Moderate skier (no adjustment) |
How to Use This Calculator
Collect measurements
Record weight, height, age, binding boot sole length (mm), and decide skier type based on speed/aggression.
Enter data
Switch between imperial and metric inputs as needed. Boot sole length is always in millimeters.
Review DIN output
Check the recommended DIN along with conservative and aggressive alternatives to understand how setting changes affect release.
Get professional adjustment
Take the calculated reference to a certified technician who will perform official tests (torque wrench) before skiing.
Formula
DIN = f(Skier Code, Boot Sole Length) from ISO 11088 release value table
Skier code combines weight and height, adjusted for skier type (±1 code) and age (−1 code for ≤9 or ≥50). Boot sole length determines the column in the release table. DIN values increase with shorter boot soles or more aggressive skier types.
ISO 11088 outlines proper binding setting procedures. This calculator approximates the official tables but does not replace shop calibration tools. Use it to learn how different factors influence release values.
Ski Binding Safety Tips
Proper DIN settings balance retention (staying clipped in) and release (preventing injury). Conditions, terrain, and skill level should influence how conservative or aggressive you set bindings.
Best practices
- Re-test bindings annually or after hard impacts.
- Adjust DIN when weight, boots, or ability changes significantly.
- Inspect heel/toe pieces for ice, debris, or worn AFDs before every ski day.
When to go lower
- You are a beginner, recovering from injury, or skiing mellow terrain.
- Riding in deep powder where slow falls can twist knees.
When to go higher
- You ski aggressively at high speed or race gates.
- You consistently eject from bindings in-bounds despite clean technique (consult a tech first).
Frequently Asked Questions
What is DIN?
DIN (Deutsches Institut für Normung) is the scale used to calibrate ski bindings for proper release torque.
Do I need a pro to adjust my bindings?
Yes. Technicians use certified tools to verify both lateral and vertical release torque after adjustment.
Why does boot sole length matter?
Shorter boots need higher spring tension to achieve the same torque; longer boots require lower DIN for equivalent release force.
Does temperature or snow affect DIN?
Spring temperatures and snow buildup under the boot can influence release. Keep bindings clean and perform shop tests each season.
Can I use this for kids?
Children under 48 kg (105 lb) require junior-specific bindings and charts. Consult a shop; this tool assumes adult bindings.
