Vertical jump calculator

Your vertical jump — the reach you gain leaving the ground — from your standing reach and jump reach, or entered directly. From the height it also derives your hang time and, with your body weight, an estimate of peak leg power (Sayers formula).

The Vertical jump calculator turns Input mode, Standing reach (cm), Jump reach (cm), Jump height (cm, direct mode), Body weight (kg, for power) into Vertical jump (cm), Vertical jump (in), Hang time (s), Peak power (W), instantly and for free. For instance, with Input mode = Standing & jump reach, Standing reach (cm) = 240, Jump reach (cm) = 300, Jump height (cm, direct mode) = 60 and Body weight (kg, for power) = 80 it returns Vertical jump (cm) = 60, Vertical jump (in) = 23.622 and Hang time (s) = 0.7.

How to use it

  1. Enter your values: Input mode, Standing reach (cm), Jump reach (cm), Jump height (cm, direct mode), Body weight (kg, for power).
  2. Read the result instantly: Vertical jump (cm), Vertical jump (in), Hang time (s), Peak power (W).

Frequently asked questions

How does the Vertical jump calculator work?

It takes Input mode, Standing reach (cm), Jump reach (cm), Jump height (cm, direct mode) and Body weight (kg, for power) and derives Vertical jump (cm), Vertical jump (in), Hang time (s) and Peak power (W) from them. The calculation is live as you type, so the result updates on every change.

Which values does the calculator ask for?

5 values: Input mode, Standing reach (cm), Jump reach (cm), Jump height (cm, direct mode) and Body weight (kg, for power). Nothing else is required — no account, no file upload.

What does a typical calculation look like?

With Input mode = Standing & jump reach, Standing reach (cm) = 240, Jump reach (cm) = 300, Jump height (cm, direct mode) = 60 and Body weight (kg, for power) = 80, the calculator returns Vertical jump (cm) = 60, Vertical jump (in) = 23.622 and Hang time (s) = 0.7. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

How much does the result change with different inputs?

It moves a lot. Using Input mode = Direct jump height, Standing reach (cm) = 480, Jump reach (cm) = 600, Jump height (cm, direct mode) = 120 and Body weight (kg, for power) = 88 instead, Vertical jump (cm) goes from 60 to 120 — which is why it is worth testing a few scenarios rather than trusting a single figure.

Which “Input mode” option should I choose?

You can pick between « Standing & jump reach » and « Direct jump height ». Each one changes what the calculator works out, so switch and compare — the default is « Standing & jump reach ».

What does it give for smaller values?

Scaled down to Input mode = Standing & jump reach, Standing reach (cm) = 120, Jump reach (cm) = 150, Jump height (cm, direct mode) = 30 and Body weight (kg, for power) = 72, Vertical jump (cm) comes out at 30. The relationship is worth checking at both ends before you rely on a single result.

When would I actually use this?

Programming a block: estimating a one-rep max without testing it, setting working loads as a percentage of it, and tracking whether volume is actually going up.

What is the most common mistake?

Estimating a one-rep max from a high-repetition set. The formulas hold to about five reps; beyond ten they drift badly, because endurance starts to dominate strength.

What is the difference between the Vertical jump calculator and the Lift percentage of 1RM calculator?

This one returns Vertical jump (cm) and Vertical jump (in); the Lift percentage of 1RM calculator returns Weight to load (kg). That is the whole difference — open the one whose figure you need.

Is there a tool for the next step?

One-rep max (1RM) calculator is the closest one after this: Estimate your one-rep max from a weight lifted for several reps (Epley formula).
