(Obligatory lowercase text)
In reply to annna g: width/height. i make yours to be +1.04

In reply to annna g: id say the same as hvituit well the +3

In reply to higherclimbingwales: I'm sure its arm span - height rather than divided. Giving either a + or - number in the value of the measurement.

Isn't the numerical value is irrelevant anyway, as you can only have a positive negative or natural ape index.

So annna has an ape index of +3 inches?

Its a RATIO, so Span/Height = Index

What if you have no hands or arms! your index will be negative then!

To quote the Wikipedia page you linked:

'The ape index is usually defined as the ratio of arm span to height.However, an alternative approach is height subtracted from arm span with the result being positive, 0 or negative. Unlike the unitless ratio, this calculation produces a numeric value in the units of measurement used to represent the height and arm span.'

The bit in bold is what is normally referred to as 'ape index' in climbing.
