Important Safety Note

Always have a certified ski technician make the final DIN adjustment on your bindings. Improper settings can lead to serious injury. This calculator provides a starting reference only.

The skier code comes from weight and height (whichever gives the lower letter), moves one row down for Type II and two for Type III, and one row up at age 50+ or 9 and under; the boot sole length picks the column. A technician sets and release-tests the binding with your actual boots.

How It Works

DIN, named for the Deutsches Institut für Normung, is the release value that tells your ski bindings how much twisting and forward-lean force should make them let go of your boot. Set too high, a binding may not release in a fall; set too low, it can let go while you are skiing. Lower-leg fractures are the injuries most clearly tied to bindings that did not release: in a Dutch case-control study of 1,148 skiers, the odds of a leg injury were 3.3 times higher when both bindings failed to release. This tool reads your starting value off the standard chart.

The chart comes from ISO 11088 (current edition 2023) and is reproduced in every binding maker's technical manual. Weight gives one skier code (A for 10-13 kg up to M for 95 kg and over) and height another (H for 148 cm and under up to M for 195 cm and over); the calculator takes whichever letter is closer to the top. Type II skiers move one row down the chart and Type III two, while skiers aged 50 or older or 9 and under move one row up. Your boot sole length, printed on the heel of the boot in millimetres, picks the column, and the cell where row and column meet is the setting.

Treat the number as the value a technician should start from, not a replacement for one. A certified shop sets the toe and heel, checks forward pressure for your boots and release-tests the binding with a torque tester, and worn or non-standard boot soles change the answer. Overstating your ability is the costliest input error, since each Type step moves the setting a full row higher.

Example: Two Skiers, Two Rows of the Chart

  1. 1 Skier 1: 170 lb (77 kg), 5 ft 10 in (178 cm), age 30, Type II, boot sole 310 mm. Weight gives code K (67-78 kg) and height gives K (167-178 cm), so the starting code is K.
  2. 2 Type II moves one row down to L; at 30 there is no age adjustment. In the 291-310 mm column, row L reads 6.5, so the starting DIN is 6.5.
  3. 3 Skier 2: 143 lb (65 kg), 5 ft 7 in (170 cm), age 32, Type III, boot sole 290 mm. Weight gives J (58-66 kg) and height K, so the chart uses J, the letter closer to the top. Type III moves two rows down to L, and the 271-290 mm column reads 7.0.
  4. 4 Both skiers end up on row L, but the shorter boot puts Skier 2 half a point higher. Had Skier 1 been 52 years old, the age rule would move the code back up to K and the setting down to 5.5. Take the number to a certified technician, who sets and release-tests the binding with your boots.

Frequently Asked Questions

What DIN setting should I use for skiing?
DIN settings are determined by your height, weight, age, boot sole length, and skier type (ability and aggressiveness). For adults between about 130 and 210 lb the ISO 11088 chart gives roughly 3 to 7.5 for Type I (cautious) skiers, 4 to 8.5 for Type II and 5 to 10 for Type III; children and light adults sit lower. Always have a certified technician set your bindings.
What happens if my DIN is set too high or too low?
DIN set too low causes premature releases during normal skiing, which can be dangerous at speed. DIN set too high can stop the binding from releasing in a fall; lower-leg fractures are the injury most clearly linked to bindings that did not release. Knee ACL tears are common in skiing too, but research has not found any binding setting that reliably prevents them.
Should I adjust my own DIN settings?
No. Always have a certified ski technician adjust your bindings. Bindings that fail to release are linked to lower-leg fractures, and in a 2020 Swiss accident-prevention survey nearly half of skiers had bindings that were not set correctly. A shop tech follows the standardized chart and tests the release with your boots to make sure the bindings work.
