A little perspective
Adult in a spacesuit vs Elkhorn coral colony: height comparison
The suited standing height of an adult in a spacesuit is about 1.58 times the colony height of an elkhorn coral colony.
An adult in a spacesuit is a person wearing a pressurised suit and life-support system for survival outside Earth's atmosphere.
An elkhorn coral colony is a branching formation of the coral species Acropora palmata, found in shallow Caribbean reefs.
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.
Measurements, assumptions & sources +
Adult in a spacesuit
Defined suited standing height: 1.9 m; defined specimen; range 1.8 m–2 m.
A defined standing astronaut 1.9 m high and 145 kg while wearing an extravehicular spacesuit and life-support backpack. Suit configuration and wearer vary; mass is not weight and the helmet top defines the calibrated height.
The marked defined suited standing height is calibrated. Unmeasured illustration details are representative.
Elkhorn coral colony
Defined colony height: 1.2 m; defined specimen; range 60 cm–2 m.
A defined mature elkhorn coral (Acropora palmata) colony 2 m wide and 1.2 m high. Branch growth and breakage produce irregular colonies; the basal reef substrate is excluded from both spans.

The marked defined colony height is calibrated. Unmeasured illustration details are representative.

Why this measurement?
Why we use 1.9 m
We compare the suited standing height of an adult in a spacesuit. This is an illustrative comparison value, not a claim that every example is the same. The recorded range is 1.8 m to 2 m.
A defined standing astronaut 1.9 m high and 145 kg while wearing an extravehicular spacesuit and life-support backpack. Suit configuration and wearer vary; mass is not weight and the helmet top defines the calibrated height.
