You have a huge range of widths to choose from when making a ski purchase, from 60mm racing skis to 130mm big-mountain sleds designed for extreme places like Alaska. Without a doubt, skis are trending wider by the year: the 2016 models are almost unrecognizable compared to even a decade ago. Below we examine the factors that play into your ski buying decision, including a look at width-related ski categories, new technologies that are helping make wide skis better for all-mountain use, and the importance of location and ability.

Ski Width Measurement

Shaped skis have been around for a number of years, and their hourglass appearance is prominent on downhill models. Reflecting the variable width silhouette, there are three common points of measurement: at the tip (the shovel or most often the widest part of the ski), the middle (waist), and the bottom (tail). Ski dimensions are measured in millimeters and often include three numbers in the following format: 128-98-118mm (tip-waist-tail). The most important number for the majority of skiers is the middle number, also referred to as waist or width underfoot, and this what many people use to analyze ski width.

Ski Categories Defined

Generally, a narrow ski excels in turn initiation and carving, and therefore is used for racing and general use on hardpack. They are also easier to handle for beginners still putting together the basics on balance and edging. However, these skis immediately sink under the surface in powder and require a lot of effort to keep the ski tips up. Wide skis, on the other hand, have more surface area and therefore provide more flotation (think snowshoes as an example). This means that they perform great in powder, but take much more effort to turn and are less nimble and sloppier on groomers. All-mountain skis fall somewhere in the middle as the most versatile type of ski that, at least in theory, can handle most conditions reasonably well.

In a perfect world, you would have a few pairs of skis in your quiver: a good narrow ski for carving on hardpack, a wide ski for those beautiful powder days, and a nice all-rounder for variable conditions and terrain. Many of us don’t have that luxury, however, so it’s important to dial in a ski width that will perform best throughout the season.

Unfortunately, you won’t find universal ski categories in terms of waist width. There is a lot of common ground, but different manufacturers and retailers all have their own definition of all-mountain skis, powder skis, etc. As examples, below are ski categories based on width from three leading online retailers:

Ice/scraped hardpack/race conditions: 60-70mm
Groomed packed powder: 70-90mm
Ungroomed packed powder: 85-105mm
Crud/chop: 100-115mm
Powder: 110+

All-mountain: Up to 85mm
All-mountain wide: 84mm to 105mm
Powder: 110+

Groomed trails: <85mm
Mostly groomed trails with some time in powder: 85mm to 95mm
Ideal all-mountain width: 96-110mm
Ungroomed terrain: 111+mm

New Technology Bridges the Gap

As we mentioned above, the trend in the ski industry definitely is getting wider. Why the changes? Over the past handful of years ski manufacturers have put a lot of effort into making their wide skis friendlier on groomers improving carving ability, edge control and stability. In 2013, for example, Rossignol revamped its lineup of S Series skis, which used to be primarily powder skis with widths in the 100mm range. One of the major changes was Air Tip technology: a honeycomb-style insert in the tips of the skis that lightens them up considerably (Rossignol claims by 20 to 30%). This is great for powder, where it’s easier to keep your ski tips up, not to mention less carrying weight when they are on your back. But it also pays off at the resort when you can take a traditional wide ski like the Rossignol Sky 7 at 98mm and easily flick it around curves. Throughout the industry, reducing the swing weight of a ski has become a high priority in delivering all-mountain versatility to these wider models.

In addition to drops in weight, edge control on wide skis has improved substantially over the years. Many older skis had simple profiles that consisted of traditional camber tip to tail, which means that the middle of the ski was bowed or raised up with contact points at the top and bottom of the ski. Then rocker, or reverse camber, was developed to keep the tips and tails of powder skis out of the deep snow. People soon realized that skiing with rocker on hardpack helped with maneuverability and reduced the tendency to catch an edge in a turn. And by using a milder form of rocker—meaning a smaller percentage of the tip and/or tail of the ski is raised off the ground—issues with either end flapping at high speed on groomers have been eliminated in most all-mountain models. Hence the evolution of rocker/camber, which includes the best of both ski types and one of the reasons why wider skis have become much more versatile.

Many all-mountain skis in 2016 are relatively wide and have a rocker/camber profile with mild rocker at the tip (and sometimes at the tail) for flotation in soft snow and camber underfoot for edge control and turn initiation. The result is that wide skis now have much greater power and turn more easily than they once did. Combine this with lighter overall weights and the incorporation of advanced materials—including carbon fiber—that stiffen up the skis for a more responsive ride, and the 90mm to 100mm width range has transitioned from being limited powder skis to now having true all-mountain capabilities.

Location, Location, Location

Now that we’ve established what prominent retailers think and what ski technology means in terms of width, another final consideration is the type of conditions that you will ski most. Let’s first take a look at the annual snowfall in some popular ski locations:

Stowe, VT: 333 inches per year
Vail, CO: 348 inches per year
Breckenridge, CO: 353 inches per year
Alta, UT: 514 inches per year
Crystal Mountain, WA: 486 inches per year
Mt. Baker, WA: 701 inches per year
Whistler, B.C.:  469 inches per year
Aleyska, AK: 720 inches per year

As you can see, there are huge variations in annual snowfall around North America. It’s worth noting that all snow in not created equal: Washington State, for example, gets more snow than Colorado but the moderate temperatures and high annual rainfall make for conditions that can vary from light and powdery to wet and slushy. Both Colorado and Utah have fantastic snow: they stay cold during the winter and the air is dry, so less snow goes a lot further in creating great conditions. And the final lesson from this chart: we should all go to Alaska to ski!

The bottom line is that where you ski should dictate the width of your ski. If you live on the East Coast of the United States, unfortunately you can expect very few powder days and therefore a narrower ski designed for hardpack (80mm to 90mm waist) will suit you best. If you live in Bellingham, Washington, and Mt. Baker is your home resort, you definitely want to buy at the wide end of the ski spectrum (100m+) as you can expect a high percentage of powder days.

Ability Level

Location matters, but so does the parts of the resort you will end up skiing most. Even beginner skiers in snow-heavy places like Colorado and Utah will spend the vast majority of their time on groomed runs, and therefore a narrower ski is best. Intermediate and advanced will be pushing the boundaries more, both literally and figuratively, and a wider ski makes the most sense. Experienced skiers also will be able to control their skis better, and therefore can take on a wider and stiffer ski that would be challenging for beginners.

Finding the Sweet Spot

To help bring everything full circle, we’ve created our own criteria for ski width selection below. Of course, the specific model you choose matters in the equation, but we feel it’s a good general picture of where things stand in 2016.

Race and GS Skis: 60mm to 70mm
Beginner Skis: 70mm to 80mm
Groomer/East Coast Skis: 80mm to 90mm
Ideal All-Mountain East Coaster: 88mm to 90mm
Heart of the All-Mountain Range: 88mm to 100mm
Ideal All-Mountain Rocky Mountains/West Coaster: 98mm to 100mm
Powder/Big Mountain Skis: 105mm+

If you only plan on buying one ski and are an intermediate to advanced skier, we think that the true sweet spot for all-mountain use is the 90mm to 100mm range. The skis will be nimble enough to carve but wide enough to get some float in the deep stuff. Groomer skiers and East Coasters should look in the 70mm to 90mm range, and West Coasters in the 90mm to 100mm range. If you’re looking to get off-piste in the deep snow, you can start at 105mm and get all the way up to 130mm.
