Many elements, including height, weight, ability level and terrain, determine the proper ski length. Though they lack stability at greater speeds, shorter skis are more nimble and lively. Starting with a ski length chart that recommends a variety of skis depending on your height will help you most.
Furthermore important is the weight of the skier. Heavier skiers may need a longer ski to maintain stability at higher speeds since they apply more effort to the ski than do lighter skiers.
Generally speaking, you should pick a ski whose length roughly matches your height. While intermediate and advanced skiers should pick longer skis, beginners usually want skis that reach their chin.
Remember, too, that performance of a ski depends more on its form than on its length. The sidecut radius—created by the tip, waist, and tail dimensions—determines the size or scope of a turn the ski can generate. For beginners, sizing up on a stiff ski might thus be suitable to provide stability at speed. This is particularly true with skis that excel in tight tree skiing or moguls.
Apart from weight and height, your preferred form of skiing as well as your degree of competence matter. Skis turn differently, hence a longer ski could be less manoeuvrable at slower speeds.
While lighter skiers will choose a softer ski that feels lighter on the snow, heavier skiers may want a stronger ski for stability. For better high-speed stability, more experienced skiers may want a longer ski.
Beginning skiers should search for a ski whose length falls between five and ten centimetres less than their height. This will enable them to turn quickly and with short radius under easy control. For balanced performance on every terrain, intermediate and experienced skiers can think about a ski their height or 5cm shorter. Those who enjoy carving tight, quick turns often choose broader tips and shorter waists. Some skiers will want a larger tail that resists sideways skidding; the tail of the ski also helps sustain turns.
The correct ski length is ultimately one that balances stability with ideal control. While advance skiers who ski aggressively on various terrain would frequently pick longer skis, beginners often choose shorter skis.
Apart from the above described elements, the form and flex of a ski will also affect its perfect length. For first-time skiers, a softer flex is simpler to turn; in deeper snow, a rockered form provides more float.
Finally, the mount point—which directly relates to your stance and skiing technique—can also affect the sensation of a ski. While skis with a higher mount point are fit for strong, straight lining, those with a lower mount point offer a more centred and balanced skiing stance. Having said all of that, the best approach to determine your ideal ski length is to go out and test several possibilities! Fortunately, most resorts provide rentals and demos so you may experience the feel of each ski.
