Vertical Jump Calculator
Calculate your vertical jump power and compare to athletic benchmarks.
Estimate peak power from jump height and body weight.
Jump Analysis
Vertical jump is one of the best measures of lower body explosive power. It is widely used in basketball, volleyball, and football combine testing.
Measuring your vertical:
- Stand flat-footed and reach as high as you can (standing reach)
- Jump as high as you can and mark your peak height
- Vertical jump = Peak height − Standing reach
Power formulas:
- Sayers Equation:
Peak Power (W) = 60.7 × Jump Height (cm) + 45.3 × Body Mass (kg) − 2055 - Lewis Formula:
Average Power = √(4.9) × Body Mass × √(Jump Height) × 9.81
Vertical jump benchmarks:
- Under 16 in (40 cm): Below average
- 16–20 in (40–51 cm): Average
- 20–24 in (51–61 cm): Above average
- 24–28 in (61–71 cm): Good (competitive athlete)
- 28–32 in (71–81 cm): Excellent (college/pro level)
- 32–36 in (81–91 cm): Elite
- 36+ in (91+ cm): World class
NBA average: ~28 inches (71 cm) NFL combine top: ~40+ inches (102+ cm)
