What Your Result Means

How This Calculator Works

Your vertical jump height is the difference between your maximum reach (highest point you can touch) and your standing reach (height of your reach standing flat). Measure both in inches or centimeters. If you provide body weight, the calculator applies the Sayers equation to estimate peak power output: P = 60.7 × h + 45.3 × w − 2055, where h is jump height in centimeters and w is body weight in kilograms. This gives insight into your leg's explosive capability.

Quick Questions

How do I measure standing reach?

Stand with your arm extended overhead against a wall. Mark the height of your fingertips on the wall. Use a measuring tape or ruler to measure from the floor to that mark.

What is a good vertical jump?

Average for untrained adults is 16–20 inches. College athletes typically jump 24–28 inches. NBA average is around 28 inches. Elite athletes exceed 35 inches.

What is the Sayers equation?

A biomechanics formula developed to estimate peak power output from vertical jump height and body weight. It's widely used in sports science and athletic testing protocols.

Does body weight affect vertical jump?

Yes. Peak power scales with body weight—heavier athletes need more force to jump. However, relative jump height (jump height divided by body weight) is a better measure of explosive capability.

How can I improve my vertical?

Plyometric training (box jumps, depth jumps), strength training (squats, lunges), and proper warm-up technique all contribute. Consistency and proper form matter more than intensity.
