A 50 cm, 3.5 kg example. Not a health or growth benchmark.
Defined examples — our methodology
The marked length is calibrated. Unmeasured illustration details are representative.
A defined adult standing 1.75 m tall with a mass of 70 kg. This is a consistent comparison specimen, not a global average or health benchmark.
