What Is a Vertical Jump Calculator?
This tool calculates jump height from hang time (time spent in the air) using basic projectile motion physics.
Calculate vertical jump height from hang time.
This tool calculates jump height from hang time (time spent in the air) using basic projectile motion physics.
Useful for tracking vertical jump training progress, common in basketball, volleyball, and general athletic testing.
Measure how long you're airborne during a jump (often via video analysis).
Input your measured time.
The result updates automatically.
Height = (g × t²) ÷ 8, where g is gravity (9.8 m/s²) and t is total hang time.
Slow-motion video analysis or specialized jump testing equipment provides the most accurate hang time measurement.
Related concept, but direct measurement devices (like a Vertec) measure height directly rather than calculating from time.
No, this is a pure physics calculation based on hang time - actual jump technique affects your hang time but not this formula itself.
No, calculations happen entirely in your browser.
This varies enormously by sport, training level, and individual factors - there's no single universal benchmark.
The physics formula applies to hang time regardless of jump type, though measurement technique should be consistent for comparison.
Yes, vertical jump tracking is common in these sports for measuring explosive power development.
Yes, plyometric and strength training are commonly used to improve vertical jump performance over time.
