7 Best Free Online Ape Index Calculator Websites

Here is a list of the best free online ape index calculator websites. Ape Index is slang that is used to describe the ratio of the wingspan and height. Wingspan or arm span is the measurement between the tips of the fingers when arms are spread straight wide. As per the ape index, the arm span should be equal to the height of the body. In that case, the body has a perfect ape index ratio which is 1. The perfect ape index is an ideal human-body ratio. Not having a perfect ape ratio is not bad. In fact, it is said that having an ape index greater than 1 can be a competitive advantage.

This post covers 7 free websites where you can calculate your ape index ratio. Each of these websites has an ape index calculator where you can add your wingspan/arm span and height to determine the ratio. All these calculators are identical in terms of the ape ratio calculation. However, some can work with multiple measurement units. This allows you to put your measurements in your locale unit system instead of converting to the supported unit system first. You can go through the post and check these out yourself.
