Water Ski Size Calculation Formula

Ski Size = Base Size + Height Adjustment + Weight Adjustment - Skill Level Adjustment

• Base Size: Starting point based on average adult size (e.g., 67 inches)
• Height Adjustment: Add or subtract inches based on height difference from average (e.g., +1 inch per 2 inches above average height)
• Weight Adjustment: Add or subtract based on weight difference from average (e.g., +1 inch per 20 pounds above average weight)
• Skill Level Adjustment: Subtract inches for higher skill levels (e.g., -2 inches for intermediate, -4 inches for advanced)

For a 5’10” tall, 180-pound intermediate skier:

67 (base) + 1 (height) + 1 (weight) - 2 (intermediate) = 67 inches

How to Determine Water Ski Size?

To determine the appropriate water ski size:

• Measure Height and Weight: Accurate measurements are crucial for proper sizing.
• Assess Skill Level: Beginners need longer, wider skis for stability, while advanced skiers can use shorter, narrower skis for better maneuverability.
• Consider Skiing Style: Slalom skiing typically requires different sizes than trick or jump skiing.
• Use a Calculator or Chart: Input your measurements and skill level into a reputable online calculator or consult a sizing chart.
• Adjust for Preferences: Some skiers prefer slightly longer or shorter skis based on personal comfort.
