Are you an extreme sports enthusiast looking to take your passion outdoors? If so, then it’s important to know the answer to the question: what size ski do I need? Several factors go into determining this, such as length, width and flexibility.

To make sure you have a safe and enjoyable experience on the slopes or in other outdoor conditions, understanding these elements is essential for finding skis that fit both your body type and activity level.

With proper knowledge of how different sizes can affect performance, skiing will be much more rewarding! So let’s explore what size ski you need before taking off down the mountain.

Ski Length

Ski length is an important factor to consider when selecting the right ski for you. Several factors should be taken into account, such as your height, weight, skiing ability and style of skiing.

Factors to Consider

When choosing a ski length it’s important to take into consideration your height, weight, and skill level. Generally speaking, skis come in sizes ranging from around 140 cm up to 200 cm or more depending on the type of ski.

The taller you are the longer the ski should be and vice versa for shorter people. Your weight also plays a role in determining what size ski is best for you; heavier skiers will need a longer ski than lighter skiers with similar heights.

Lastly, your skill level can help determine which size is best suited for you; beginners may want something shorter while experienced skiers may prefer something longer depending on their style of skiing.

How To Measure Ski Length

The easiest way to measure what size of ski would work best for you is by standing next to them and seeing how they compare with your body size – if they reach just above or below your chin then this could be a good starting point when looking at different lengths available.

You can also use an online calculator which takes into account all these factors (height, weight etc.) before giving recommended sizes based on various types of skiing styles such as alpine/downhill or cross-country/backcountry etc.

Recommended Ski Lengths

For beginner downhill/alpine skiers who weigh between 80-100 lbs., suggested lengths range from 140-150 cm; those weighing 100-130 lbs., 150-160 cm; 130-150 lbs., 160-170 cm; and those weighing 150+ lbs., 170+cm respectively.

For intermediate downhill/alpine skiers who weigh between 80-100 lbs., suggested lengths range from 145–155 cm ; those weighing 100–130lbs , 155–165cm ; 130–150lbs , 165–175cm ; and those weighing 150+lbs , 175+cm respectively.

Experienced downhill/alpine skiers who weigh between 80 – 100lbs suggest lengths range from 150 – 160cm ; those weighing 100 – 130lbs, 160 – 170cm ; 130 – 150lbs, 170 – 180cm ; and those weighing 150 + lbs, 180 + cm respectively.

Cross country / backcountry recreational touring weights vary greatly due to individual fitness levels so please consult with local experts before purchasing any equipment specific to this activity.

Ski Width

Ski width is an important factor to consider when selecting the right ski for you. The width of a ski can affect its performance and how it handles on different terrain. Here are some factors to consider, how to measure ski width, and recommended sizes for different types of skiers.

Factors to Consider

Ski width affects the stability, maneuverability, and control of your skis on various terrain. A wider ski will provide more stability at higher speeds while a narrower one will be more maneuverable in tight turns or bumps. Skier weight also plays a role in determining the ideal ski size; heavier skiers need wider skis for better support while lighter ones may prefer narrower ones for easier turning ability.

How To Measure Ski Width

Ski width is measured from tip-to-tail at the widest point of the waist (the middle section). This measurement should be taken with calipers or another measuring device that can accurately read millimeters (mm).

For beginners and novice sports enthusiasts looking for all mountain skiing capabilities, we recommend choosing a mid-width range between 80mm – 90mm depending on their weight class as follows: Lightweight Skiers (less than 150lbs) – 80mm; Medium Weight Skiers (150 – 200lbs) – 85mm; Heavyweight Skiers (200+ lbs) – 90 mm.

If you’re an advanced skier looking for specific performance characteristics such as speed or agility then you may want to look into narrow or wide options ranging from 70 mm – 100 mm respectively based on your preference and skill level.

Ski Flexibility

Ski Flexibility is an important factor to consider when selecting the right skis for your needs. The flexibility of a ski affects its performance, and it’s important to choose a ski that fits your skill level and terrain preferences.

Factors to Consider

Several factors can influence the flex of a ski, including weight, height, ability level, type of skiing you plan on doing (downhill or cross-country), and the type of snow conditions you’ll be encountering. Generally speaking, heavier skiers will need stiffer skis while lighter skiers may prefer softer ones.

Taller people tend to need longer skis with more flex than shorter people do. Beginners should look for softer models while experienced racers may want stiffer ones.

Lastly, different types of skiing require different levels of stiffness; downhill skiing requires stiffer models while cross-country skiing benefits from more flexible models due to their maneuverability in tight turns and over varied terrain.

Shopping For Skis

When shopping for new skis, it is best to test them out before buying to get an idea of how they feel underfoot and how they perform in various conditions. To test the flexibility, push down on each end with both hands at once; if there is too much resistance then the ski may be too stiff for your needs, while if there isn’t enough resistance then it could be too soft.

Additionally, try turning each end independently as this will give you an indication as to how well the ski will turn when going downhill or making sharp turns on flat surfaces like groomed trails or icy slopes. If one side feels harder than the other then this could indicate uneven pressure distribution which would affect performance negatively during turns or jumps off moguls/bumps etc.

Ultimately, everyone’s preference is unique so it is recommended to test out different pairs beforehand. This will help you determine which ski best suits your size/weight/ability and terrain preferences.


In conclusion, when deciding what size ski you need, it is important to consider the length, width, and flexibility of the ski. Ski length should be based on your height and weight while ski width should be based on your skill level. Lastly, the flex of a ski will depend on how aggressively you want to ride. With all these factors in mind, you can find the perfect size ski for yourself that will provide an enjoyable experience out on the slopes!
