All Mountain Skis Sizing: How to Pick the Right Length in 6 Steps

All mountain skis sizing comes down to a few measurements and a clear sense of how you ski. Start with your height and weight, adjust for your ability level and the terrain you ride most, then check the result against the manufacturer’s size chart for the specific model. This guide walks through each step so you can land on a length that feels stable at speed and still turns easily in soft snow.

Why All Mountain Skis Sizing Is Different From Other Categories

Ski length is usually given in centimeters, and the number you want depends on what the ski is built to do. Racing skis run long for stability at high speed. Powder skis run longer still to keep you floating. All mountain skis sit in the middle. They are designed to handle groomers, variable snow and the occasional deep day, so their recommended lengths are typically a little shorter than a dedicated powder ski of the same height and weight.

That middle position is the reason sizing feels confusing. A rider who would size a powder ski at 180 cm might be better off at 170 to 175 cm on an all mountain model, because the shorter ski is easier to pivot on firm snow and still has enough surface area in powder. The goal is balance between control and float, not the longest ski you can handle.

Step 1: Measure Your Height and Weight Accurately

Start with two numbers. Stand barefoot against a wall, measure your height in centimeters, and weigh yourself in pounds or kilograms, depending on which chart you use. Most manufacturers publish sizing charts that list a length range for each height and weight combination. If you are between sizes or your weight falls outside the typical range, move to the next step before choosing.

• Height in centimeters, measured without shoes
• Body weight in kilograms or pounds, with your ski gear in mind (boots and helmet add weight but are not usually counted)
• Your boot size, since boot fit affects how the ski feels underfoot
• The brand’s own size chart, printed or saved on your phone

Step 2: Match Your Starting Length to the Size Chart

Once you have your height and weight, find the matching row on the manufacturer’s chart. Charts vary by brand, so do not assume a 170 cm ski from one company behaves exactly like a 170 cm ski from another. The table below shows a general reference for intermediate to advanced all mountain skiers. Treat it as a starting point and confirm against the brand’s specific guidance for the model you are considering.

Height (approx.)	Weight (approx.)	Typical all mountain length range
5’0″ to 5’4″ (152 to 163 cm)	100 to 130 lb (45 to 59 kg)	150 to 165 cm
5’4″ to 5’8″ (163 to 173 cm)	130 to 160 lb (59 to 73 kg)	160 to 172 cm
5’8″ to 6’0″ (173 to 183 cm)	160 to 190 lb (73 to 86 kg)	170 to 182 cm
6’0″ and taller (183 cm and up)	190 lb and up (86 kg and up)	178 to 190 cm

Step 3: Adjust for Your Ability Level

Ability changes the answer more than most people expect. Within the ranges above, the choice should shift based on how you ski:

• Beginner to early intermediate: Choose the shorter end of the range. Shorter skis turn with less effort and are more forgiving when you are still learning to edge and balance.
• Strong intermediate: Stay near the middle of the range. This is where most all mountain skiers land.
• Advanced and expert: Move toward the longer end for higher-speed stability, especially if you ski firm snow at speed or charge big mountain terrain.

If you are unsure which category fits, be honest with yourself about the runs you are comfortable on. A skier who still feels tense on steeps should not buy the longest ski on the chart.

Step 4: Factor In the Terrain and Snow You Ski Most

All mountain skis are versatile, but your typical conditions still matter. If most of your days are groomed runs and hard-pack at resorts in the Rockies, a length toward the lower-middle of your range will feel quick and lively. If you spend more time in deep snow, especially the powder-heavy days common in parts of Utah and Montana, a length toward the upper-middle helps with float. Many skiers who split their time evenly choose the middle of the range and rely on the ski’s sidecut and rocker profile to handle both conditions.

Also consider the ski’s width. A wider all mountain ski has more surface area and floats better, so some riders choose a slightly shorter length to offset the extra width and keep turn radius manageable. Check the manufacturer’s notes on waist width and recommended length together, not separately.

Step 5: Check the Ski’s Turn Radius and Rocker Profile

Two specifications change how a given length skis. Turn radius, listed in meters, indicates how tight the ski wants to turn. A shorter ski with a small turn radius feels playful and quick. A longer ski with a larger radius feels stable and planted. Rocker, the upturned tip and tail, helps the ski stay on top of soft snow and makes it easier to initiate turns. Rockered all mountain skis often feel more forgiving, which can justify a slightly shorter choice without losing stability.

Look at the full specification sheet before committing. Two skis of the same length can feel very different depending on sidecut and camber.

Step 6: Test, Compare and Confirm

The final step is to test the length if you can. Demo programs at resorts let you try several lengths of the same model in one day, which is the most reliable way to confirm your choice. Pay attention to how the ski responds when you carve on a groomer, how stable it feels at higher speed and how easily it pivots in variable snow. If you cannot demo, ask the shop or a knowledgeable friend to check your measurements against the chart and your skiing style.

1. Measure height and weight accurately.
2. Find your row on the brand’s size chart.
3. Adjust up or down based on ability.
4. Factor in your typical terrain and snow.
5. Review turn radius, rocker and width.
6. Demo two lengths if possible, then confirm.

Tools and Accessories That Help With Sizing

You do not need much to size your skis, but a few items make the process easier. A tape measure, a bathroom scale and a printed copy of the brand’s size chart cover the basics. Many skiers also bring their boots to the shop or demo fitting, since boot flex and width influence how the ski performs underfoot.

Common Mistakes

• Choosing the longest ski for bragging rights. Overly long skis are harder to turn and tire you out faster on groomers.
• Ignoring ability. Height and weight are only part of the picture.
• Using a powder ski’s chart for an all mountain ski. Powder models run longer, so the numbers will push you too far up.
• Comparing lengths across brands. Two 170 cm skis can ski quite differently.
• Skipping the demo. A single afternoon on two lengths often settles the question better than any chart.
• Forgetting boot fit. A poorly fitting boot changes how you stand on the ski and can make a correct length feel wrong.

FAQ

Are all mountain skis shorter than powder skis?

Usually, yes. Powder skis are typically built longer to keep you floating in deep snow. All mountain skis are often a few centimeters shorter than a powder ski for the same skier, which keeps them easier to turn on groomers.

Should I size my all mountain skis to my height or my weight?

Use both. Most size charts combine height and weight to set a range, and then ability and terrain help you choose within it. If the two measurements point to different sizes, your weight and skiing style often matter more.

What if I am between two lengths?

Choose the shorter length if you are newer or prefer quick turns, and the longer one if you ski fast, prefer stability or spend more time in deep snow. Demoing both is the most reliable way to decide.

Does a wider all mountain ski need to be shorter?

Often, a wider ski is paired with a slightly shorter length, because the extra width adds surface area and float. Always check the manufacturer’s recommendation for the specific model rather than applying a general rule.

Can beginners ride all mountain skis?

Yes. Many all mountain models are forgiving, especially those with rocker and a moderate turn radius. Beginners should choose the shorter end of the recommended range for their height and weight.

Does boot size affect ski length?

Not directly, but boot fit and flex change how you balance on the ski. A poorly fitting boot can make a correct length feel off, so get boots fitted properly before finalizing your ski choice.

How often should I re-check my ski length?

Check it when your fitness, skiing ability or the terrain you prefer changes significantly. A skier who moves from groomers to more aggressive terrain may want to revisit their length after a season or two.

Conclusion

All mountain skis sizing becomes simple once you work through the steps in order: measure, consult the brand chart, adjust for ability, factor in terrain, and confirm with a demo if you can. Keep in mind that the shorter end suits quicker turns and the longer end suits stability and float. Use the table here as a starting point, then trust the brand’s guidance and your own feel on snow.
