Vertical Jump Calculator — Measure & Improve Your Jump Height
Use our Vertical Jump Calculator to quickly convert test results, estimate jump height from simple inputs, and get targeted training guidance. Whether you measure a standing vertical, a running vertical, or estimate from force/flight time data, this tool helps you track progress and set realistic goals.
What Is Vertical Jump?
Vertical jump (vertical leap) is the maximum height a person can elevate their center of mass from a standing or running takeoff. Coaches use vertical jump to quantify lower-body power and explosiveness — key traits for basketball, volleyball, track & field and many team sports.
Why Measure Your Vertical?
- Performance tracking: See training gains over weeks and months.
- Goal setting: Know the vertical needed for specific skills (rim touch, dunking, blocking).
- Program design: Tailor strength and plyometric work to the athlete’s needs.
How This Calculator Works
The calculator supports common measurement methods and converts between units:
- Flight time → jump height: Converts measured air time into jump height using standard physics formulas.
- Reach + max touch → jump height: Subtracts standing reach from peak touch height to compute vertical.
- Manual input: Enter test numbers (inches or cm) and get instant conversions and normalized results.
How to Measure Accurately
- Standing reach: Measure fingertip height while flat-footed with a fully extended arm.
- Jump test: Use a Vertec, jump mat, contact mat, or consistent video timing to capture peak reach/flight time.
- Multiple trials: Take 3 maximum efforts and record the best valid jump for accurate tracking.
Training Tips to Improve Vertical
- Strength: Focus on compound lifts (back squat, deadlift, split squats) to build maximal strength.
- Explosiveness: High-quality plyometrics (drop jumps, bounding, box jumps) with proper progression.
- Technique: Practice optimal approach, arm swing and posture for transfer of power.
- Recovery & load management: Track fatigue, allow adequate rest and prioritize nutrition and sleep.
Interpreting Your Results
Typical benchmarks (general guideline): recreational athletes ~15–25 in (38–64 cm), competitive high school athletes ~20–30 in (50–76 cm), elite jumpers 30+ in (76+ cm). Use the calculator’s unit toggle to view results in inches or centimeters.
Frequently Asked Questions
Which method is most accurate: flight time or reach difference?
Both methods are valid. Flight time (with a high-quality jump mat or slow-motion video) is reliable; reach difference (measured peak touch minus standing reach) is the most direct field test when using a Vertec or marked wall.
How often should I test my vertical?
Test every 4–8 weeks during a training block to monitor progress without over-testing. Use consistent protocols for reliable comparisons.
