Ski dimensions refer to the three numbers printed on modern skis that indicate their width at different points along their length.
All modern skis feature a set of dimensions, typically presented as three numbers, which describe their width. These numbers help determine the ski's shape and how it performs on the snow. For example, a ski might have the dimensions 122-86-115.
Here's what each number in the sequence represents:
- First Number: Tip Width - This is the width of the ski at its widest point near the front (the tip). In the example 122-86-115, the tip width is 122mm.
- Second Number: Waist Width - This is the narrowest point of the ski, located directly under your boot. In the example 122-86-115, the waist width is 86mm.
- Third Number: Tail Width - This is the width of the ski at its widest point near the back (the tail). In the example 122-86-115, the tail width is 115mm.
These three measurements — tip, waist, and tail width — define the ski's sidecut. A ski with a larger difference between the tip/tail widths and the waist width typically has a deeper sidecut, which makes it easier to turn quickly. Skis with straighter sidecuts (less difference between the numbers) are generally more stable at high speeds.
Understanding the Dimensions
Let's look at the example again in a table format:
| Ski Part | Measurement Example (122-86-115) | Description |
|---|---|---|
| Tip | 122mm | Widest point at the front of the ski |
| Waist | 86mm | Narrowest point under your foot |
| Tail | 115mm | Widest point at the back of the ski |
These dimensions are crucial indicators of the ski's intended use and performance characteristics, guiding skiers in choosing the right equipment for different snow conditions and skiing styles.
