Skis - Baseline Knowledge

When you start to talk about skis, it's important that you have a working knowledge of the different parts and each skiers different needs. This blog provides you with a baseline of understanding, so that you can hold your own in a conversation about what ski is best for what use...


Skis are measured in centimeters. Most adults skis are between 160cm and 200cm in length. The length of the ski that you purchase should be in line with your height and weight...but those that are new to skiing may want a shorter ski for better control.

Here's a baseline size chart:

Waist and Turn Radius

The waist is the area directly underfoot. This is often where the width of the ski is measured. Wider skis are best for powder, but they are also harder to handle for beginners.

The wider a ski, the longer the turn radius. Here's a short video about how this works:

Ski Profile: Camber vs. Rocker vs. Early Rise

Camber is a concave profile that allows for better snow contact and more pop coming out of turns. The rocker, on the other hand, is a ski profile with a more upturned tip and tail for deep snow conditions.

A flat or early rise ski, is a ski profile that has a flatter bottom with upturned tips. This is good for deep snow.

The following video delves into camber, flat/early rise and rockered skis:

Din Setting

The DIN setting, short for Deutsches Institut für Normung (German Institute for Standardization), is a ski setting that determines the amount of force that can be placed on a binding before it releases. This is set based on your weight, height and ability level. The DIN setting is usually adjusted by a ski shop professional, because if the ski doesn't release when you need it to, you will break your leg.

Touring Bindings

There are two standard types of bindings for the backcountry, frame bindings and tech bindings. Frame bindings are a heavier binding that aren't as good for touring, but perform exceptionally well in downhill terrain. They also operate better as crossover in-bounds/out-ofbounds bindings.

Tech bindings (or pin bindings) have a pin and hole system and attach directly to the boot. These are the go to bindings for ski touring and ski mountaineering. They don't operate as well in an in-bounds setting.

Frame and tech bindings release differently, so when people have a release malfunction, the injuries look different. Frame bindings tend to lead to knee injuries (meniscus, ACL, MCL, etc.), while tech bindings tend to lead to broken bones.


Skiing and backcountry skiing are equipment heavy sports, and we could talk tech all day. And while this isn't a comprehensive list of terms and concepts, it is a solid introduction.
