Adult in a spacesuit
An adult in a spacesuit is a person wearing a pressurised suit and life-support system for survival outside Earth's atmosphere.
Also known as: astronaut in spacesuit, adult wearing an EVA suit
How big is it?
1.9 m tall
Also 6.234 ft
Defined suited standing height · defined specimen
Typical recorded range: 1.8 m to 2 m.

A little perspective
About 1.58 times the defined colony height of Elkhorn coral colony.
Elkhorn coral colony: An elkhorn coral colony is a branching formation of the coral species Acropora palmata, found in shallow Caribbean reefs.
Measurements, assumptions & sources +
Adult in a spacesuit
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
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.
NOAA Fisheries — Elkhorn coral
The marked defined colony height is calibrated. Unmeasured illustration details are representative.

Why we use 1.9 m
For comparison, this page uses defined suited standing height. This is labelled defined specimen: an explicit comparison model rather than a claim that every example has the same value. The recorded range is 1.8 m to 2 m.
