How to Choose The Right Ski
Whether you’re brand new to skiing or a seasoned pro, you should always consider the following things when choosing your ski:

Stylized text - Length
Choosing the right ski can be daunting with so many different options available, but the first thing to consider is the length of the ski. The right length is determined by a skier’s height, weight, ability level and a general idea of what terrain the skier will be skiing. Generally at Lone Pine, we say that a ski should be anywhere from chin height to head height, or a bit longer for more aggressive, expert skiers.

Stylized text - Width
Width measurements are discussed with three main points of note: tip, waist and tail, with the most important being waist measurement. Measured in millimeters, the ski width profile is shown in the following format: ( 134/110/125 ) with the first number denoting tip width, the second denoting waist and the third being tail measurement. The waist measurement gives the quickest and easiest insight into the overall surface area and what type of skiing the ski will be best for.

A narrower waist width allows the skier to transfer from edge to edge quicker making the ski more responsive, but sacrifices float. A wider waist width spreads the skier’s weight out across a larger surface area allowing the ski to float better in soft snow. A groomer ski typically has a waist width of 88mm or, all mountain ranges from 88mm - 108mm, and powder skis are typically wider than 108mm.

Stylized text - Profile
The profile of ski refers to the shape of the ski when viewing from the side. Based on the profile of the ski, different parts will sit closer or further from the snow when a ski is unweighted. Rocker and Camber are the two main profile concepts used by modern ski manufacturers, and it is commonplace for skis to utilize a combination of both in their construction.
Illustration of cambered ski profile
A cambered ski rises in the center when placed on a flat surface, line an "n" shape. Camber provides more resistance when a skier or rider exerts downward forces on the center of the ski or board. This translates to more power, stability and precise edge grip. A cambered ski provides better performance on harder snow.

Rocker was first introduced as a way to provide better float in deeper snow. Essentially the opposite of camber, rocker describes a ski shape where the center of the ski or board touches the ground in the middle and progressively rises towards the tip and tail, like a "u" shape. It is often referred to as "early rise" in the tip of the ski or board.

Modern skis often incorporate a combination of rocker in the tip/tail and camber underfoot, what's often referred to as a "hybrid" rocker profile. A hybrid of the two shapes combines the maneuverability of rocker with the edge hold of a cambered profile allowing the skis to perform better in a wider variety of snow conditions.
Stylized text - Stiffness/Radius
When considering the construction of a ski, there are two main things to look at: the materials used in the core of the ski, and the ski’s radius. Stiffer core materials and longer radii make the ski stiffer and more stable, but harder to turn as quickly. The stiffer the ski and longer the radius, the more aggressively the ski will need to be skied.
Side view of ski core construction
Most skis are built based on a foam or wood core with certain models containing layers of metal, carbon fiber, fiber glass or other composite materials added to receive desired stiffness and snow feel. Foam cores are typically the softest cores making them the easiest to flex and turn. Form is found mostly in beginner style skis. Wood is the basis for most skis on the market. Adding metal layers to a ski makes it stiffer and more stable, but adds to the overall weight of the ski. Utilizing carbon fiber or similar composite materials give skis similar stiffness characteristics to metal at a lighter weight.

The "Sidecut" of a ski is created by the difference in width between the tip/tail and waist of the ski. The Radius of a ski or snowboard is the measurement of the imaginary circle (in meters) created by a ski's sidecut if it continues in its circular pattern. Shorter radius skis are meant to turn quicker. A longer radius ski is meant to make longer turns and is more stable at higher speeds. Beginner to intermediate skiers are generally more comfortable on a shorter radius ski because it is easier to make a tighter turn and control the ski. Though skis are designed with many different applications, longer radius skis are normally better suited for advanced and expert skiers.

No two skis are built the same, and every skier is different. When considering what ski to buy, it's imperative to consider all these attributes and how they play together. Remember, all skis are purpose built for different styles of terrain, speed, snow conditions and ability levels.
