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. Typically, a person’s arm span should be less than their body height; an increased arm span to body height ratio of >1.05 is considered a positive sign for Marfan syndrome.

How is arm span calculated?

For adults and older children, the easiest method to measure arm span is by doubling the distance between the sternal notch and the tip of the middle finger of an extended arm [5].
