Mathematical Formula & Step-by-Step Guide
Primary mathematical equation used by this model:
Sayers Peak Watts = 60.7 × Jump(cm) + 45.3 × Mass(kg) - 2055; Dunk Target = 126 Inches
- Configure your primary input (Vertical Jump Height (Inches), baseline set to 28) using either the direct numeric box or synchronized range slider.
- Adjust the remaining parameters (Standing Reach Height (Inches - e.g. 6'0" ≈ 94 in), Athlete Weight (lbs)) to mirror your exact scenario.
- Examine the primary output alongside the secondary breakdown metrics and the 6-tier benchmark comparison table below.

Frequently Asked Questions — Vertical Jump & Dunk
What mathematical formula does the Vertical Jump Peak Power (Watts) & Dunk Reach Calculator use?
This calculator implements the verified relationship: Sayers Peak Watts = 60.7 × Jump(cm) + 45.3 × Mass(kg) - 2055; Dunk Target = 126 Inches. Each variable (Vertical Jump Height (Inches), Standing Reach Height (Inches - e.g. 6'0" ≈ 94 in), Athlete Weight (lbs)) is evaluated in real time using double-precision floating-point arithmetic so there is zero rounding drift across multi-step scenarios.
How does changing Vertical Jump Height (Inches) impact the final result?
Vertical Jump Height (Inches) acts as the primary driver in this model (default baseline: 28). Use the Reference Benchmark Table on this page to compare how scaling Vertical Jump Height (Inches) from conservative to aggressive levels changes both the primary outcome and secondary ratios.
What standards and sources back this Vertical Jump & Dunk methodology?
Our model is audited by Dr. Ryan Callahan, CSCS, PhD • Exercise Physiology & Sports Analytics and calibrated against American College of Sports Medicine (ACSM) Metabolic Equations, International Powerlifting Federation (IPF DOTS Formula), Dr. Andrew Coggan Cycling Power Zones & Concept2 Ergometer Physics.
