How do I measure vertical jump height?

Use a vertical jump test like a Vertec device, jump mat, or the standing-reach-minus-jump-reach method against a wall, all of which give jump height in centimeters or inches (convert to cm here).

How accurate is the Sayers equation?

It's a validated field estimate correlating well with force-plate-measured power, but like all jump-based power equations, it's an approximation rather than a direct force-plate measurement.

Sayers Vertical Jump Power Calculator

Estimate peak anaerobic power output from a vertical jump test using the Sayers equation, which combines jump height and body mass. Widely used in sports science to assess explosive lower-body power without force-plate equipment.
