Height is the best place to begin. However, it’s only one factor and not where the conversation about ski length should end. 

Height 

The traditional starting point is to pick a ski that stands up somewhere between your chin and the top of your head. Taller skiers generally need longer skis for the proportional surface area required to generate edge pressure and float. Additional factors help pick what length in that range is right for the ski you’re looking at. 

Weight 

Heavier skiers need more ski underfoot to distribute weight effectively, particularly in soft snow. Skiers the same height with very different weights shouldn’t be skiing the same length ski, especially in powder. If you're on the heavier side for your height, add 5 to 10cm. If you're lighter than average for your height, stick to the lower end of the range. 

Skill Level 

Beginners benefit from shorter skis. A shorter ski is easier to turn, quicker to pivot, and more forgiving of some weight distribution mistakes. An advanced skier needs more length for the edge control and stability at higher speeds. Intermediate skiers sit in the middle, and terrain preference starts to matter more.  

Ski Type and Terrain 

The type of ski you pick and the terrain it’s suited for are as important as any other factor. A 175cm all-mountain ski and a 175cm powder ski are not the same ski for sizing purposes. Skis with more rocker, like powder skis typically have, feature a shorter effective edge the same length ski with a longer camber pocket. This means they’ll feel shorter for their stated length, especially on firmer snow.  

Park skis are generally sized a bit shorter for maneuverability. Freeride and powder skis are commonly sized longer for added float and stability. All-mountain skis are somewhere in the middle.  

Park and Freestyle Skis 

Many skiers size down on park skis vs all-mountain, freeride, or powder skis. The shorter length means less swingweight for easier spins and more control rails. It’s common for park-focused skiers choose a ski 5 to 10cm shorter than their all-mountain ski length. If you’re skiing an ARV 84, ARV 88, or ARV 94 primarily in the park, consider choosing the shorter length in your size range. For more general all-mountain use, consider sizing up by around 5 cm.  

All-Mountain Skis 

All-mountain sizing is the most flexible category. The goal is a ski that handles groomed runs, off-piste, and variable snow without being a liability in any of them. Most skiers land in the nose-to-forehead range here, with terrain preference, weight, and skill level providing the fine-tuning.  

For example, you might size up on an ARV 94, ARV 100, or Antimatter 100 for off-trail capability while choosing a slightly shorter Antimatter 92 for snappier carving response. It depends on precisely what you’re looking for the ski to do best.  

Powder and Freeride Skis 

This is where it makes sense to size up. Powder skis are wider and rely on surface area and rocker for float. If you ride a ski at 177cm in all-mountain conditions, size up to something in the 182-185cm range for a dedicated powder or freeride ski.  

This way the ski will provide the float an stability you need in deep snow and steep terrain, while the increased rocker on skis like the ARV 112 or Antimatter 114 will keep the ski feeling manageable when initiating turns in tight spaces.    

For touring and backcountry, consider the snow conditions your ski most. If you ski a lot of powder on something like the Locator 112, size up near the top of your range. If you’re on something narrower for spring missions where weight is a critical and tight kick turns are a priority, size down as appropriate.  

Women's Skis 

Women's-specific sizing follows the same general principles. All Armada skis are built with identical shapes and constructions regardless of whether they’re labeled men’s or women’s skis. The only difference is in the graphic options offered, so factor in height, weight, skill level and terrain choice in the same way as described above. 

Women who are tall, aggressive skiers should feel comfortable picking a ski from the men’s collection if the sizing suits them better or if they prefer the men’s graphic option. For example, women who want to ski a 188cm ARV 106 or a 182cm Antimatter 100 (as opposed to a 180cm ARW 106 or 175cm Antimatter 100 W) can confidently know they’re getting the exact same skis, but in the lengths they need.  

Should I Size Shorter or Size Longer? 

Size Shorter in Your Skis If: 

• You are a beginner or early intermediate — shorter means faster, easier turns and a more forgiving ski underfoot 
• You primarily ski park and freestyle — spinning, pressing, and maneuvering favor shorter length 
• You ski mostly groomed terrain at moderate speeds — you don't need the length for float or high-speed stability 
• You are lighter than average for your height 
• You are returning to skiing after a long break — shorter gives you more confidence while you rebuild muscle memory 
• You want a more playful, maneuverable feel overall 

Size Longer in Your Skis If: 

• You are an advanced or expert skier who skis at high speeds — longer skis are more stable at speed 
• You ski powder or soft snow regularly — more length means more float 
• You are heavier than average for your height 
• You primarily ski big-mountain, freeride, or off-piste terrain 
• You want a ski that holds a high-speed edge without chattering 
• You are switching to a heavily rockered ski from a more cambered model — cambered skis have more effective edge contact and can feel longer than a rockered ski at the same stated length 

ARV & ARW Series (ARV 84, 88, 94, 100, 106, 112) (ARW 84, 88, 94, 100, 106) 

The ARV and ARW Series are Armada's playful all-mountain series. All ARV and ARW skis have Freestyle Rocker — tip and tail rocker with camber underfoot. Wider models have longer rocker lines, which reduces effective edge length making the ski feel shorter. Size up toward the mid-to-upper end of your range on wider models like the ARV 106 and ARV 112. 

• ARV 84 (143-171cm): Entry-level all-mountain twin. Beginners and intermediate skiers should stay in the 143-157cm range. Advanced park-focused skiers at 5'8" to 5'10" land at 157-164cm. 
• ARV 88 (156-181cm): More edge hold and pop than the 84. Park and all-mountain use. A 5'10" intermediate skier: 166-176cm. 
• ARV 94 (157-185cm): Versatile crossover. All-mountain to park. A 5'10" advanced skier: 171-178cm. 
• ARV 100 (158-186cm): The all-mountain twin standard. A 5'10" advanced skier: 172-179cm. Size up if you ski more powder than groomers. 
• ARV 106 (164-188cm): Powder-leaning twin. Size to the upper end of your range. A 5'10" advanced skier: 180-188cm. 
• ARV 112 (165-192cm): Dedicated soft-snow ski. Size long. 185-192cm for most advanced skiers above 5'8". 

The Zero Collection (Stranger 100, Kimbo 95, ARV 116 JJ UL, ARV 106 Ti) follows similar logic. The ARV 106 Ti adds Titanal damping to the ARV 106 platform — same sizing guidance applies. 

Antimatter Series (AntiMatter 82, 88, 92, 100, 108, 114) 

The Antimatter line uses either All-Mountain Rocker (82, 88, 92) or Freeride Rocker (100, 108, 114). Nearly all these skis utilize Speedmetal titanal construction, which is stiffer than ARV and ARW and thus a big more demanding to ski at the same length. 

• Antimatter 82 (166-182cm): Narrow frontside carver. Size to the middle of your range. Stiff and precise; don't go short expecting more maneuverability. 
• Antimatter 88 (160-184cm): Frontside with all-mountain capability. A 5'10" advanced skier: 168-176cm. 
• Antimatter 92 (164-188cm): All-mountain with frontside ambitions. A 5'10" advanced skier: 172-180cm. 
• Antimatter 100 (154-189cm): Wide all-mountain to freeride. Size to the upper half of your range. A 5'10" advanced skier: 175-182cm. 
• Antimatter 108 (176-191cm): Big-mountain freeride. Size long. Most advanced skiers above 5'8" are at 184-191cm. 
• Antimatter 114 (181-193cm): Maximum big-mountain performance. Full-length for most skiers. 

Locator Series (Locator 96, 104, 112) 

Touring-first construction. Ultralight Caruba cores and low rocker lines for efficient uphill travel with capable downhill performance. Size at the top of your range. These skis are narrow enough that you want the length for stability on descents. 

• Locator 96 (157-185cm): All-conditions backcountry. A 5'10" skier: 171-178cm. 
• Locator 104 (162-186cm): Everyday backcountry freeride. A 5'10" skier: 178-186cm. 
• Locator 112 (166-187cm): Big-day, high-speed backcountry powder ski. 180-187cm for most advanced skiers above 5'8". 

Junior Skis (ARV 84 JR, ARV 100 JR, AntiMatter 84 JR, AntiMatter 92 JR) 

Junior sizing is driven by height and weight more than skill level. A useful rule: junior skis should come up to the child's chin or nose when standing flat. The ARV 84 JR runs 133-150cm. The Antimatter 92 JR runs 133-163cm. The Antimatter 84 JR runs 144-162cm. The ARV 100 JR runs 140-164 cm.

FAQ 

How do I choose ski length if I don't know my skill level?

Be honest about where you spend most of your time and at what speed. A skier who stays on groomed blue runs at controlled speeds is an intermediate regardless of years on snow. Skill level is about technique and terrain, not time. If in doubt, size toward the shorter end of intermediate. It's easier to progress on a ski that's slightly too short than one that's too long. 

What length skis do I need as a beginner?

For ski length for beginners, target a ski that comes up to your chin or slightly below. A shorter ski is easier to control and turn at lower speeds, which matters more than anything else when you're learning. On the Armada side, the ARV 84 (143-150cm) and Antimatter 84 JR + EM10 rental setup are good entry points. Most adult beginners land in the 140-160cm range depending on height. 

Should I size up or down for powder skis?

Size up. Powder skis need length to float effectively. If your all-mountain ski is 175cm, your powder ski should be 180-185cm or longer. On the Armada lineup, the ARV 106, ARV 112, Antimatter 108, and Antimatter 114 are built for this purpose. Don't apply all-mountain sizing to a dedicated powder ski. 

How does ski width affect ski length choice?

Wider skis have more surface area and float, which means you can sometimes ski a slightly shorter length in powder without losing performance. But width is not a substitute for length on stability at speed. As a general rule, on skis over 105mm underfoot, size at or near the top of your range. On skis under 90mm, size more precisely to your height and skill level. 

What is the ski sizing guide for women specifically?

Ski sizing for women follows the same height, weight, skill level, and terrain logic as any other skier. Use the sizing chart above, then adjust for weight and terrain. Armada's ARW series and Antimatter women's lineup run the same construction the men's equivalents. If the only appropriate length is in the men’s collection, women can confidently choose that ski and know it will perform as needed.  

Is the ski length chart based on the ski standing upright or lying flat?

The stated ski length is measured along the running length of the ski from tip to tail. The sizing chart in this guide references stated ski length in centimeters, which is what you'll find listed on every product page at armadasnow.com.

What length skis should I get for park skiing?

Park ski sizing runs 5 to 10cm shorter than all-mountain sizing. A 5'10" intermediate skier who skis a 178cm all-mountain ski should consider something closer to 170cm in a dedicated park setup, though personal preference still plays a crucial role here.  

Do I need a different ski length for moguls and bumps?

Shorter skis are generally easier in bumps. A shorter, more maneuverable ski pivots faster between bumps and requires less effort in tight fall lines. If bumps are a primary terrain for you, stay at the shorter end of your range.  

What does effective edge have to do with ski length?

Effective edge is the portion of the ski that actually contacts the snow. A rockered ski has less effective edge than a cambered ski of the same stated length because the tip and tail are lifted. This is why you can ski a longer rockered ski than you might expect. A 185cm rockered powder ski may feel more manageable than a 175cm cambered carving ski, even though the rockered ski is technically longer. 

How do I size Armada skis specifically?
