Han and Lean developed equations for predicting the height of an adult from the arm span. The authors are from the Glasgow Royal Infirmary.
Patient selection: Caucasian adults from Glasgow from 17-18 years to 70+
Arm span is taken as the distance between finger tips in centimeters with arms held outstretched horizontally and the person standing against the wall. No mention is made of which fingers are used; the distance between the index and middle finger tips may range from 0.5 to 1.0 cm.
height for adult male in cm =
= (0.762 * (arm span in cm)) + 40.7
height for adult female in cm =
= (0.693 * (arm span in cm)) + 50.3
