## What is the relationship between arm length and height?

An example of a human body ratio is a person’s arm span—the distance from the middle fingertip of the left hand to that of the right hand when stretching out both arms horizontally—to their height. This ratio is approximately a one to one ratio, meaning that a person’s arm span is about equal to their height.

### How do you test for Marfan syndrome?

Quick screening tools include comparing the patient’s arm span to their body height as well as assessing for unusually hypermobile joints.
