'anthropometrically' originates from Greek roots via New Latin/Modern formation: Greek 'anthrōpos' (ἄνθρωπος, 'human') + Greek 'métron' (μέτρον, 'measure'), combined into Late Latin/Modern New-Latin forms that produced 'anthropometry' and then English 'anthropometric' + adverbial suffix '-ally'.

'anthropometrically' developed from English 'anthropometric' (adjective), which itself comes from the noun 'anthropometry' (coined in the 19th century from New Latin/Greek 'anthropometria'), and the adverb was formed by adding the suffix '-ally' to the adjective ('anthropometric' → 'anthropometrically').

Initially related specifically to the 19th-century practice of measuring human bodies for classification or scientific study; over time it has broadened to describe any design, analysis, or statement that is based on human body measurements.
