Very simply, DIN is set according to your weight, boot sole length and ability. Given those variables, you probably fall between a 4 and 8 on the DIN scale depending on those variables. You can ski on a binding with a maximum DIN of 10 or 12. Some heavier skiers, or with small boot soles and special need might use bindings with maximum DINs of 14 or 18, and some top racing bindings go even higher.
When you present your skis for mounting at the shop, you will fill out a form that asks you to provide your height, weight, skier type, and you will provide your boots. The tech will set your DIN setting on the equipment you buy, and will verify the equipment is current, and appropriate.
To set DIN follow these instructions and consult the attached chart. There are special notations below for backcountry bindings that do not apply to you, the settings are otherwise the same. This information from www.wildsnow.com
|Instructions: Choose your "Skier Code" using weight and height, then follow line to right and choose DIN that corresponds to your boot sole length. IMPORTANT: Pick your skier type below, then use following correction factor: Type1, use value you figured in table, without correction. Type 2, choose value one line below (one step higher number). Type 3, use value two lines below (two steps higher). Age correction: If over 50 years old reduce setting one step. And finally: if you choose to set your bindings yourself for backcountry skiing or resort skiing, subtract at least 1/2 din number from settings you figured from this chart, then ski bindings at resort to test. If you come out of toe or heel, slightly increase release setting of toe or heel (not both). Continue to fine-tune using this method. To be safe, have your binding settings checked by a qualified technician.
Skier types: Type 1: Careful skier preferring moderate terrain, or a beginner skier. Type 2: Skiers preferring average speeds and somewhat difficult runs. Type 3: Few skiers in this category; racers, extreme skiers, prepared to take risks, ski at high speeds. Most backcountry skiers are Type 2.
