The height of a human is about 1.59 times the carapace length of a green sea turtle. Selected basis: a defined specimen of Green sea turtle; an example for Human; approximate values.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions. Horizontal rulers compare the selected spans; vertical brackets also identify height on the artwork.
1.1 m - Carapace length; defined specimen.
The green sea turtle is a marine reptile that grazes on seagrass and algae in tropical and subtropical seas.
A chosen 1.1 m carapace length and 150 kg mass. Head and flippers extend beyond the shell.

A human is a primate of the species Homo sapiens, distinguished by habitual upright walking, language and complex tool use.
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.
