Ape Index (Wingspan to Height Ratio) Calculator

Formula

The formula to calculate the wingspan to height ratio is:

\[ APE = \frac{W}{H} \]

Where:

\(APE\) is the wingspan to height ratio
\(W\) is the total wingspan measured from fingertip to fingertip
\(H\) is the height measured from feet to head

What is a Wingspan to Height Ratio?

A wingspan to height ratio is a ratio of the length of a person’s wingspan to their height. A wingspan is a measure of length from the tip of one hand to the other when they are extended out as far as possible on either side of the body.

The typical wingspan to height ratio is right around 1. Those with ratios greater than 1 would be considered to have long arms in relation to their body.

Example Calculation 1

Let's assume the following values:

Wingspan (W) = 72 inches
Height (H) = 70 inches

Using the formula:

\[ APE = \frac{72}{70} = 1.0286 \]

The Ape Index is 1.0286.

Example Calculation 2

Let's assume the following values:

Wingspan (W) = 68 inches
Height (H) = 68 inches

Using the formula:

\[ APE = \frac{68}{68} = 1.0000 \]

The Ape Index is 1.0000.
