Vertical Jump Power Calculator

Calculate your vertical jump power output using the Lewis formula, which estimates power production based on your body weight and vertical jump height. This calculator is essential for athletes, coaches, and trainers to measure explosive strength and track power development over time.

Why Use This Calculator?

Measure explosive power output in watts
Track strength and conditioning progress
Compare power-to-weight ratios
Evaluate athletic performance
Set training goals and benchmarks

How It Works

The calculator uses the Lewis formula to estimate power output:

P = √4.9 × body mass × √jump height

Where:

P = Power output in Watts
Body mass in kilograms
Jump height in meters

Understanding Your Results

Power Output Ranges

Level	Power Output (Watts)
Elite	> 8000
Advanced	6000-8000
Intermediate	4000-6000
Beginner	< 4000

Note: These ranges are approximate and vary by sport and position.

Tips for Testing

Warm Up Properly
- Dynamic stretching
- Light cardio
- Practice jumps
Measuring Jump Height
- Use a Vertec device
- Chalk mark on wall
- Force plate
- Jump mat
Testing Protocol
- Stand with feet shoulder-width apart
- Countermovement to 90° knee bend
- Jump straight up
- Land softly in same position
- Take best of 3 attempts
