This tool will calculate your ape index by comparing your arm span to your height, giving insight into your body proportions.

## Ape Index Calculator

### How to Use the Ape Index Calculator

To use this calculator, input your height in centimeters into the height field, then input your wingspan (the measure from fingertip to fingertip with arms outstretched) also in centimeters into the wingspan field. Then, click the “Calculate” button to see your Ape Index.

### How the Ape Index is Calculated

The Ape Index is calculated by dividing your wingspan by your height. The result is a number that represents the ratio between these two measurements. An Ape Index greater than 1 means your wingspan is greater than your height, which can be an advantage in sports like rock climbing. An Ape Index less than 1 means your wingspan is less than your height.

### Limitations of the Ape Index Calculator

It is important to note that the Ape Index is a simple ratio and does not take into account other factors that might contribute to athletic performance or the proportions of the rest of the body. This calculator assumes that the entered measurements are accurate and uses standard arithmetic for calculation. Errors in measurement or input can lead to incorrect results.
