Vertical Jump Calculator
For Athletes, Coaches, and Fitness Enthusiasts
- Elite: > 70 cm (>27.5 in)
- Very Good: 60–69 cm (24–27.5 in)
- Above Avg: 50–59 cm (20–23 in)
- Average: 40–49 cm (16–19 in)
- Below Avg: 30–39 cm (12–15 in)
- Poor: < 30 cm (<12 in)
For female and youth: subtract ~15–20% from these numbers for rough comparison.
- Jump height from flight time: h = (g × t²) / 8, where h = height (meters), g = 9.81 m/s², t = flight time (seconds)
- Jump height from reach: h = Jump Reach – Standing Reach (in cm or inches)
- Takeoff velocity: v = √(2gh)
- Power: Power = (60.7 × jump height [cm]) + (45.3 × body mass [kg]) – 2055 (Sayers formula)
- Force at takeoff (estimate): F = m × (g + v / tpush) (tpush ≈ 0.25s as a typical countermovement phase)
- Engage in regular plyometric training (box jumps, broad jumps, depth jumps).
- Strengthen the posterior chain (glutes, hamstrings, calves, lower back) with squats, deadlifts, and lunges.
- Work on explosive power via Olympic lifts and medicine ball throws.
- Practice technique for optimal arm swing and approach mechanics.
- Ensure adequate recovery and avoid over-training to maximize adaptation.

Vertical Jump Calculator – Measure Your Explosive Power in Seconds
Looking to measure your jump height for sports, fitness, or personal improvement? The Vertical Jump Calculator helps you figure out how high you can leap using either flight time or reach height difference. It’s quick, accurate, and designed for athletes, coaches, and fitness fans.
🔍 What Is a Vertical Jump?
A vertical jump is the height a person can leap straight up from a standstill. It’s a great indicator of leg strength, explosiveness, and overall athletic power. That’s why it’s tested in:
- 🏀 Basketball
- 🏈 Football
- 🏐 Volleyball
- 👟 Track and field
- 💪 Fitness training and CrossFit
Your vertical jump says a lot about your athletic potential.
📐 Vertical Jump Formulas
✈️ Method 1: Using Flight Time
Jump Height = (t² × g) ÷ 8
Where:
- t = Total time in the air (in seconds)
- g = Gravity (9.81 m/s²)
📏 Method 2: Using Standing Reach & Jump Reach
Jump Height = Max Jump Reach – Standing Reach
Both methods are supported by the calculator so you can choose whichever is easier to measure.
💡 How to Use the Vertical Jump Calculator
- Select your measurement method:
- ⏱️ Flight time (via a jump mat or video)
- 📏 Reach height difference
- Enter the appropriate values (time or reach)
- Click Calculate
- Get your vertical jump height in inches or centimeters
📊 Example Calculation
Method 1 (Flight Time):
You stay in the air for 0.6 seconds.
- Height = (0.6² × 9.81) ÷ 8 = 0.44145 m ≈ 17.4 inches
Method 2 (Reach):
- Standing Reach = 90 inches
- Jump Reach = 110 inches
- Jump Height = 20 inches
🧠 Why Is Vertical Jump Important?
Your vertical jump reflects your explosive power, which affects performance in many sports. Improving it can lead to:
- 🏀 Better dunks and rebounds
- 🏈 Quicker starts and direction changes
- 🏐 Higher spikes and blocks
- 🏃♂️ Faster sprints
