[[Anthropometry]] is the study of the measurements of different parts of the human body.<ref name=":j0">{{Cite web|url=https://www.cdc.gov/niosh/topics/anthropometry/|title=CDC - Anthropometry - NIOSH Workplace Safety and Health Topic|website=www.cdc.gov|access-date=2016-11-16}}</ref> Common measurements include [[Human height|height]], [[Human body weight|weight]], organ size ([[Brain size|brain]], [[stomach]], [[Human penis size|penis]], [[Human vaginal size|vagina]]), and other bodily metrics such as [[waist–hip ratio]]. Each measurement can vary significantly between populations; for instance, the average height of males of European descent is 178&nbsp;cm ± 7&nbsp;cm and of females of European descent is 165&nbsp;cm ± 7&nbsp;cm.<ref>{{Cite journal|last=Visscher|first=Peter M.|date=2008-05-01|title=Sizing up human height variation|journal=Nature Genetics|language=en|volume=40|issue=5|pages=489–490|doi=10.1038/ng0508-489|pmid=18443579|s2cid=40000233|issn=1061-4036}}</ref> Meanwhile, average height of [[Nilotic peoples|Nilotic]] males in [[Dinka people|Dinka]] is 181.3&nbsp;cm.

Applications of [[anthropometry]] include [[Human factors and ergonomics|ergonomics]], [[biometrics]], and [[Forensic science|forensics]]. Knowing the distribution of body measurements enable designers to build better tools for workers. Anthropometry is also used when designing safety equipment such as seat belts.<ref name=":j0" /> In [[biometrics]], measurements of [[fingerprint]]s and [[Iris (anatomy)|iris]] patterns can be used for secure identification purposes.<ref name="JainA">{{cite journal|year=2000|title=Biometric Identification|url=http://helios.et.put.poznan.pl/~dgajew/download/PUT/SEMESTR_10/IO/FACE_RECOGNITION/BiometricsACM.pdf|journal=Communications of the ACM|volume=43|issue=2|pages=91–98|doi=10.1145/328236.328110|author1=Jain A.|author2=Hong L.|author3=Pankanti S.|citeseerx=10.1.1.216.7386|s2cid=9321766|access-date=16 November 2016|archive-url=https://web.archive.org/web/20121107111616/http://helios.et.put.poznan.pl/~dgajew/download/PUT/SEMESTR_10/IO/FACE_RECOGNITION/BiometricsACM.pdf|archive-date=7 November 2012|url-status=dead}}</ref>
