Vertical Jump Power Calculator
Estimate peak lower-body power from vertical jump height and body mass, compare different equations, and see power-to-bodyweight outputs for athlete testing.
Why vertical jump power is more useful than height alone
Jump height is easy to understand, but two athletes with the same jump height can produce different power if their body masses are different. A vertical jump power calculator combines body mass and jump height to estimate explosive lower-body power.
Formula options
The Sayers equation is commonly used for peak power estimates from jump-and-reach testing. The PubMed record for the Sayers jump power equation paper explains the cross-validation background for vertical jump power equations.
How to use the output
Use the same jump protocol each time: same warm-up, same measurement method, and same countermovement rules. Compare power per kilogram when body mass changes, and compare absolute watts when the sport rewards total force output.
Common mistakes
Do not mix standing reach methods, phone-app flight-time measurements, and jump mats as if they are identical. Measurement method strongly affects the result.
Frequently asked questions
-
Use one equation consistently for tracking. Sayers is a practical default, but different equations can produce different watt values.
-
No. It reflects explosive power, which depends on force, speed, technique, and body mass.
-
Use both. Watts show absolute output, while W/kg helps compare athletes of different sizes.
-
Yes, if testing conditions are consistent and fatigue is controlled.
-
They predict power from field measures rather than directly measuring force and velocity with laboratory equipment.
