Why do skis need to be so long?

The reason skis are so long is because longer skis are almost always more stable at high speeds. Longer skis are also usually better in deep, soft snow (powder). But, the length depends on all the things you mentioned: skier size, experience level, and ability. Taller, heavier skiers use longer skis.

How are ski lengths determined?

The length of your ski depends on your height, weight, skiing style & ability. There isn’t an exact formula for determining the right size but in general the proper ski length should be between your chin and the top of your head. For example, a skier that is 6′ tall will want to look for a skis between 170 – 190 cm.

Should your skis be taller than you?

The correct length of skis will vary from skier to skier based on many factors, including but not limited to height and weight. The general rule is to pick a ski that is going to land somewhere between your chin and the top of your head. Pro and expert skiers may choose skis that are slightly taller than their height.

Why skis are flat and long?

The skiers use flat and long skies to slide on the snow, because larger the area of cross-section, the lesser is the pressure on the snow. Hence, a skier can easily slide on the snow without sinking his feet in it.

Why are longer skis faster?

Are Longer Skis Faster? Longer skis are technically faster if you’re pointing straight downhill because overall there is less pressure exerted on the snow and less capillary drag (source). A longer ski also gives you more confidence because it will vibrate less at speed.

What happens if skis are too long?

TLDR; Longer skis have more stability and float better in snow, but they also have a larger turning radius. Shorter skis sacrifice stability (especially at speed) but are quick to respond and easier to make short sharp turns. Short skis turn faster but long skis go faster.

Why are flat and long skis used for gliding over snow?

Due to long flat skis, the area of contact is larger. This reduce the pressure (P ∝ 1/A) exerted by the skier on the snow to enabling the skier to slide over the snow without sinking. For similar reason, it is easier to walk on muddy road if we have flat shoes rather than shoes with sharp heels.
