'nonanthropometric' is formed from the English negative prefix 'non-' plus 'anthropometric'; 'anthropometric' ultimately comes from Greek 'anthropos' meaning 'human' and 'metron' meaning 'measure'.

'anthropometric' was coined in modern scientific usage from Greek elements 'anthropos' and 'metron' (via New Latin and scientific coinage), and the English prefix 'non-' (from Old English/Latin usage as a negative) was attached to create 'nonanthropometric' as a negated adjective in contemporary English.

Originally, 'anthropometric' meant 'relating to measurements of the human body'; with the added prefix 'non-', the term now denotes the opposite: 'not relating to or not based on human body measurements'.
