is about , although premature newborns may be much smaller. Standing height is used to measure children over two years old and adults who can stand without assistance.

For sample Chumlea equation use knee height as indicator of stature. Other techniques include: arm span, sitting height, ulna length, etc. See also Anthropometry, the measurement of the human individual Human body weight List of tallest people Economics and Human Biology (academic journal) History of anthropometry Human physical appearance Human variability Pygmy peoples Citations General bibliography (for heights in U.S. and Japan) (for heights in Germany) Netherlands Central Bureau for Statistics, 1996 (for average heights) A collection of data on human height, referred to here as "karube" but originally collected from other sources, is archived here.
