Look up an initial DIN (ISO 11088) ski binding setting from weight, height, skier type, age and boot sole length, for a qualified ski technician to verify.
ISO 11088 Initial DIN Indicator Method
The starting-chart method chooses the uppermost row produced by skier mass and height, applies skier-type and age corrections, and reads the stamped boot-sole-length column. No further correction is made at 13 kg or less. This calculator conservatively excludes Type III at 22 kg or below; the checked manufacturer chart excludes codes A–C (21 kg or below). A qualified technician must determine and test the final setting.
How the Calculation Works
The calculator applies the displayed published chart, lookup, or starting-point relationship to the visible required inputs.
How to Use This Calculator
- Use this as an educational initial-indicator lookup for technician verification.
- Enter or select every visible required input and unit.
- Select Calculate and review the starting recommendation and supporting detail.
- Use Reset before starting a new scenario.
Worked Example
A 70 kg, 175 cm, age-30 Type II skier starts at code K, moves one row to L, and with a 305 mm BSL receives an initial chart indicator of 6.5.
Input and Result Guide
| Item | How to use it |
|---|---|
| Mass and height | The uppermost resulting ISO row is used when the two inputs differ. |
| Skier type | Choose the ISO I, II, or III release/retention preference deliberately. This calculator excludes Type III at 22 kg or below as a conservative scope restriction. |
| Corrections | No further skier-type or age correction is made at 13 kg or less; otherwise age 9 or younger and age 50 or older move the adjusted code up one row. |
| BSL | Use the millimeter boot-sole length stamped on the actual boot, never Mondopoint. |
| Technician test | Final setting requires compatibility inspection and calibrated release-function testing. |
Interpreting the Result
The displayed number is the chart's initial indicator or Z-mark, not a final setting and not authorization to adjust a binding. Inspection, adjustment, and torque/release checks can change the final outcome.
Assumptions and Limitations
This implementation covers the published Annex B lookup but cannot inspect boot-binding compatibility, wear, damage, mounting, forward pressure, toe height, or actual release torque. For a blank edge cell it follows the chart instruction to move horizontally to the nearest populated value and flags that adjustment.
Common Questions
Why is this a starting recommendation?
The initial chart value does not verify actual release torque. A qualified technician must follow current manufacturer instructions, inspect boot-binding compatibility and perform calibrated release-function testing; special release preferences are not modeled here.
Will my last successful calculation be restored?
Yes. The calculator saves enabled source values and the successful result in this browser. Reset clears that saved state.

The numeric table and lookup were corroborated against the MARKER 2024/25 Technical Manual, pp. 146–149. See also ISO 11088:2023 (alpine ski-binding-boot system assembly, adjustment and inspection) and ISO 11110:2015 (release-test devices). The full current ISO Annex B and current instructions for every binding model were not independently reviewed.
