Professional DIN Ski Binding Calculator
Calculate the correct release force setting for your ski bindings according to the ISO 11088 standard.
What DIN setting should I use? DIN settings range from 0.75 (young children) to 12+ (expert adults). A 75 kg intermediate adult skier typically needs DIN 6–7. The exact value depends on weight, height, age, boot sole length and skier type, following the ISO 11088 standard. DIN is the same for all binding brands (Marker, Salomon, Look, Tyrolia, Atomic). Enter your details below for a precise calculation, or see the DIN chart further down for a quick reference.
SAFETY WARNING: This ski DIN calculator is for reference purposes only. Setting your ski bindings to the correct release setting is essential for your safety. It would be best if you always had your bindings checked and adjusted by a professional ski technician. Also consider ski insurance before your trip.

What is a DIN setting?
A DIN setting is a standardized number between 0.75 and 18 that determines how much force is required to release a ski binding in a fall. Higher numbers require more force to release; lower numbers release more easily. The name DIN comes from Deutsches Institut für Normung — the German Institute for Standardization — which developed the original specification.
The correct DIN setting balances two opposing risks. A setting that is too low causes pre-release, where the binding opens during normal skiing and can itself cause falls. A setting that is too high means the binding does not open when it should during a real fall, increasing the risk of knee ligament injuries (ACL, MCL) and leg fractures.
The ISO 11088 standard defines the calculation method used by ski shops worldwide. Your DIN value is determined by a lookup table that combines your weight, height, boot sole length, age and skier type into a single recommended release force setting.
Who needs a DIN calculator?
This calculator is used by skiers of all levels to verify their binding settings before a ski trip, ski rental shops to configure bindings for customers, ski instructors setting up equipment for students, and anyone fitting new ski boots to existing bindings or upgrading to a new binding model.
How DIN is calculated
The ISO 11088 method assigns each skier a code letter (A through O) based on five inputs, then maps that code to a DIN value via a lookup table:
- Weight: Produces a numeric code. The primary factor; heavier skiers need more release force.
- Height: Produces a second numeric code. The lower of weight code and height code is used as the base.
- Skier type (I / II / III): Type I (cautious) reduces the code; Type III (aggressive) increases it. Type II (average) leaves it unchanged.
- Age: Skiers under 16 or over 50 receive a one-step reduction for added safety margin.
- Boot sole length (BSL): The final code is looked up against the BSL range to produce the DIN number. A longer sole shifts the result up.
Frequently asked questions
What DIN setting should a beginner use?
Beginners typically use DIN settings between 2 and 4, depending on weight and boot sole length. The calculator assigns skier Type I (cautious) to beginners, which produces the lowest DIN values in the lookup table, prioritising easy release over retention.
How does body weight affect DIN setting?
Weight is the primary factor in DIN calculation. Heavier skiers require more force to control the ski and therefore receive higher DIN values. A skier weighing 95 kg will typically receive a DIN 2–3 points higher than a skier of the same height and ability weighing 60 kg.
Why does age affect DIN setting?
Skiers under 16 and over 50 receive a one-step reduction in their DIN code according to ISO 11088. For younger skiers, lighter bone structure is more vulnerable to fracture. For older skiers, decreased bone density means the same force causes more injury risk.
What is boot sole length (BSL) and where do I find it?
Boot sole length is the distance from the front to the back of the boot's sole in millimetres, typically between 250 mm and 340 mm. It is stamped or printed on the boot near the toe piece or heel piece. A longer BSL creates a greater lever arm on the binding, which affects the final DIN value in the lookup table.
Can I set my own DIN or do I need a ski technician?
This calculator gives you the recommended DIN value. Turning the adjustment screw is straightforward, but the actual release torque must be verified with a calibrated binding tester to ensure it matches the setting. Most ski shops test and set bindings for free or a small fee at the start of the season.
What happens if my DIN setting is too high?
If DIN is too high, the binding will not release during a fall because more force is required than the fall generates. This significantly increases the risk of knee ligament injuries (ACL and MCL tears) and tibial fractures. Setting DIN too high is the most dangerous error.
What happens if my DIN setting is too low?
If DIN is too low, the binding releases too easily during normal skiing. This is called a pre-release. Pre-releases happen on hard turns, bumps, or at higher speeds, causing sudden ski loss and falls. Unexpected pre-release at speed can itself cause serious injury.
Do DIN values differ between binding brands?
No. The DIN scale is standardized under ISO 11088, so a setting of 6 on Marker bindings is the same release force as 6 on Salomon, Look, or Tyrolia. However, the physical adjustment mechanism differs between models, which is why a binding tester should confirm the actual release torque after any adjustment.
What DIN setting should I use for intermediate skiing?
DIN 5–7 for most intermediate adult skiers (70–85 kg). The exact value depends on weight, height, age and boot sole length. Use the calculator above with skier type Intermediate selected to get a precise value based on ISO 11088.
Are DIN settings the same for all binding brands?
Yes. DIN follows ISO 11088 and is identical for Marker, Salomon, Look, Tyrolia, Atomic, Rossignol and Fischer. The DIN number represents a specific release force in decanewtons — it is a universal standard, not a brand-specific scale.
What is a DIN chart?
A DIN chart, also called a DIN setting table, shows recommended DIN values based on skier weight, height and ability level. It is a simplified version of the full ISO 11088 calculation. See the DIN setting chart section below for a quick reference table, or use the calculator above for an exact result that also factors in age and boot sole length.
How do I adjust DIN on Marker bindings?
Marker bindings use a standard Phillips head screwdriver for DIN adjustment. Turn the screw on both the toe piece and heel piece to match your calculated DIN number — the DIN scale is printed on the binding next to each screw. The process is identical for Marker Griffon, Squire, Jester and other Marker models. After adjustment, have a certified ski technician verify the actual release torque with a binding tester.
What should my child's DIN setting be?
0.75–3.0 for most children. Use the calculator above with the Under 16 age group selected. Never increase a child's DIN to prevent pre-releases — if the binding releases too easily during skiing, consult a ski technician rather than raising the DIN yourself.
What is the DIN setting for a beginner?
DIN 4–6 for a beginner adult weighing 70 kg. Beginner DIN settings are lower than intermediate or advanced to allow easier release and reduce injury risk. For an exact result, use the calculator above with skier type Beginner selected.
DIN Setting Chart — Quick Reference by Weight and Skier Type
A 75 kg intermediate adult skier needs DIN 6–7. The chart below covers all weight ranges from 10 kg to 95+ kg across beginner, intermediate and advanced skier types. The calculator above produces a more precise value because it also factors in height, age and boot sole length per the full ISO 11088 method.

- This is a simplified reference. The full ISO 11088 calculation above also factors in height, age and boot sole length for a more precise result.
- Skier codes A–M are defined by ISO 11088 and are determined by weight, height and age combined — the calculator above derives this automatically.
- DIN values shown are for the most common boot sole length range. Use the calculator for exact results across all BSL ranges.
- These settings should be verified by a certified ski technician using a calibrated binding tester.
After setting your DIN, find the right ski length with our ski length calculator — and check your boot flex to make sure it matches your ability level.
DIN Charts by Binding Brand
DIN settings are identical across all brands: Marker, Salomon, Look, Tyrolia, Atomic, Rossignol and Fischer all follow the same ISO 11088 standard. The correct DIN value is determined by your weight, height, age, skier type and boot sole length, not by the manufacturer.
The calculator above works for all binding brands because it follows the universal ISO 11088 standard. Some brands label or adjust the setting slightly differently:
- Marker bindings: DIN range printed on the binding (e.g. Marker Griffon 13 = DIN 4–13).
- Salomon bindings: DIN adjustment screw on both toe and heel piece.
- Look bindings (including Look Pivot): same DIN scale, adjusted with a screwdriver.
- Tyrolia bindings: DIN scale on the toe piece; some models offer tool-free adjustment.
- Atomic bindings (made by Salomon / Amer Sports): identical DIN system.
- Rossignol bindings (often shared with Look): standard DIN adjustment.
- Fischer bindings: standard DIN scale.

How to Adjust DIN Settings on Your Ski Bindings
Use a Phillips #3 screwdriver to turn the adjustment screw on both toe and heel pieces until the indicator matches your DIN number. Both pieces must show the same value.
How to adjust ski bindings: Use a Phillips #3 screwdriver. Turn the toe-piece screw until the indicator matches your DIN number (clockwise = tighter). Repeat for the heel piece (must match the toe). Test by stepping in and twisting your boot laterally (toe releases) and leaning forward forcefully (heel releases). If unsure, most ski shops adjust bindings for free. Calculate your DIN number with the calculator at the top of this page first.
Once you know your DIN setting from the calculator above, here is the full step-by-step. Tools needed: a Phillips-head screwdriver (#3) or a flat-head screwdriver depending on the binding model.
- Find the DIN adjustment screws. Most bindings have two — one on the toe piece, one on the heel piece. The DIN scale is printed next to each screw.
- Set the toe piece. Turn the screw until the indicator lines up with your DIN number. Clockwise typically increases DIN (tighter); counterclockwise decreases (looser).
- Set the heel piece. Repeat on the heel piece — set it to the same DIN value as the toe piece. Both must match.
- Test the release. Step into the binding, then twist your boot laterally (toe should release) and lean forward forcefully (heel should release). If it releases too easily or not at all, re-check the setting.
- Get a professional check. If unsure, take your skis to a certified ski technician. Most ski shops adjust bindings for free or a small fee — professional adjustment includes a calibrated torque test.
Always test your bindings on the first run of the day with a gentle, intentional fall to verify they release correctly. Going to the resort? Check our ski pole length calculator for the correct pole height — and use our ski boot retirement checker to confirm your boots are still safe.
DIN Settings for Kids — What Parents Need to Know
Children's DIN settings are typically 0.75–3.0, much lower than adults, because children's joints are still developing and bindings should release more easily to prevent injury.
- Use the calculator above and select "Under 16" for the age group.
- Never raise a child's DIN setting to stop pre-releases. If bindings release too easily, the cause is usually technique or worn equipment, not DIN.
- Children grow quickly — recalculate DIN each season as weight and height change.
- Rent vs buy: rental shops always adjust bindings for your child. If you own the skis, adjust at the start of each season.
- Boot sole length matters: measure with a ruler — don't guess. See our ski boot size chart for Mondopoint conversion. For the right ski size for your child, use the ski length calculator.
