How Do You Compare?
Enter your numbers above & click Calculate to see feedback!
Jump Height Standards (male - adult / reference population)
- 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.
How is Jump Height Calculated?
- 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)
Tips to Improve Your Vertical Jump
- 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.
