The query "how tall is" is incomplete and ambiguous, but generally, it relates to the measurement of height, often of a person or object. Human height refers to the distance from the bottom of the feet to the top of the head while standing erect. Average human heights vary by country, gender, and other factors. For example, average adult male heights in various countries range roughly between about 165 cm (5 ft 5 in) to over 180 cm (5 ft 11 in).
If a more specific context is provided (such as a particular person, animal, building, or object), a precise height can be sought accordingly.
