Green sea turtle vs Fencing foil: length comparison
The carapace length of a green sea turtle is approximately equal to the maximum overall length of a fencing foil.
The green sea turtle is a marine reptile that grazes on seagrass and algae in tropical and subtropical seas.
A fencing foil is a lightweight sword used in the sport of fencing, designed for thrusting with a blunted tip.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions.
Measurements, assumptions & sources +
Green sea turtle
Carapace length: 1.1 m; defined specimen.
A chosen 1.1 m carapace length and 150 kg mass. Head and flippers extend beyond the shell.
Defined examples — our methodology
The marked carapace length is calibrated. Unmeasured illustration details are representative.
Fencing foil
Maximum overall length: 1.1 m; specified.
A senior fencing foil is limited to 110 cm overall and 500 g ready for use. The flexible blade, guard, grip and button tip are all included in the measured length.
The marked maximum overall length is calibrated. Unmeasured illustration details are representative.

Why we use 1.1 m
We compare the carapace length of a green sea turtle. This is an illustrative comparison value, not a claim that every example is the same.
A chosen 1.1 m carapace length and 150 kg mass. Head and flippers extend beyond the shell.
