📏 个 (measure word) + 头 (head) + 儿 = how big the head/body is → size
个头儿 literally stacks the generic measure word 个 with 头 (head) plus the 儿 suffix. The 头 carries the meaning of bulk or stature, so the compound names a person or thing's overall size or height.
个 — person 人 over enclosure-like component (simplified from 個)
个 is the simplified form of 個, originally a measure word for bamboo stalks. The traditional form combines 人 (person) with 固 (firm, phonetic). Over time it became the most common general-purpose measure word in Chinese, used for people and many objects without a specific classifier.
头 — 页 (head/page) + 豆 (bean, phonetic)
The traditional form 頭 combines 頁 (xié), meaning 'head', with 豆 (dòu) as the phonetic component. 頁 itself originally depicted a person with an emphasized head. The simplified form 头 is a modern shorthand that replaces 豆+頁 with a simpler shape while keeping the same meaning of 'head' or 'top'.
