Medical officers in the U.S. Army are tasked with screening, evaluatin
g, and processing soldiers in accordance with AR 600-9, the Army's hei
ght and weight standards regulation. This essay traces the origins of
the Army's weight standards to the present day. The Army's height and
weight standards have varied markedly, from the crude subjective asses
sment of selective service candidates at the local draft examination b
oards at the turn of the century to the modern, highly accurate method
s currently used in anthropomorphic research. The strictness of milita
ry recruitment and retention standards closely paralleled changing mil
itary personnel requirements in any particular era. Racial integration
and the influx of women into the ranks had noteworthy effects on this
history. The evolution of the Army's weight-control program and scree
ning standards reflects advancements in medical knowledge and technolo
gy, societal and political pressure, and the empirical tests of world
wars.
