Calculate vertical jump height

Measure standing reach and maximum jump reach with the same hand, surface, and unit. Jump reach must be higher than standing reach.

What is a vertical jump calculator?

A vertical jump calculator subtracts standing reach from maximum jump reach to estimate displacement. It measures a jump-test outcome, while the One Rep Max Calculator estimates maximal lifting strength.

How does the vertical jump calculator work?

The tool checks that both reaches use the same unit and that maximum jump reach is higher. It subtracts the two values and converts the result between inches and centimeters.

What formula does vertical jump height use?

Vertical Jump Height = Maximum Jump Reach − Standing Reach. One inch equals exactly 2.54 centimeters; the Length Converter can handle other length conversions.

Vertical Jump Height = Maximum Jump Reach − Standing Reach

How do you measure a vertical jump?

Warm up appropriately, stand flat-footed and record the highest one-hand reach, then perform consistent maximal jumps and record the highest touch. Use the same wall device, hand, footwear, and surface.

What does vertical jump height mean?

The result is the difference between the two reach marks, not total reach. Compare repeated tests under matching conditions and consider sport, age, sex, technique, and training history.

What can affect a vertical jump result?

Arm swing, countermovement depth, approach steps, reach technique, warm-up, fatigue, device resolution, and tester judgment can affect the number. Body-size context can be checked separately with the BMI Calculator, though BMI does not measure power.

Who should use a vertical jump calculator?

It is useful for athletes, coaches, trainers, and students documenting a reach test. Runners should use the Race Time Predictor, and cyclists the Cycling Power-to-Weight Calculator for sport-specific performance questions.

Frequently asked questions about Vertical Jump

Subtract standing reach from maximum jump reach.
Yes. Select centimeters and the calculator will also show the equivalent result in inches.
No. Jump reach is the highest touch point; jump height is jump reach minus standing reach.
Use the protocol required for your test and keep it consistent. Standing and approach jumps are not directly interchangeable.
Yes. Arm swing and countermovement technique can materially affect reach height.
A common practical approach is several well-rested maximal attempts, recording the best valid reach under one protocol.
The calculated displacement must be positive; otherwise the measurements were reversed or the jump touch was not above standing reach.
No. It reflects one explosive task and does not measure endurance, skill, agility, strength, or sport performance by itself.
