The average hand span of an adult is usually around 7.4 to 8.2 inches (18.8 to 20.8 cm). This can vary based on factors such as gender and height.
The average hand span of a man is 3.5 inches across and 7.6 inches in length.
the average life span of a human being is somewhere around 80 years :)
About nine inches, referred to as a span.
A hand span is about 22 to 26 centimeters.
It is predicted the world average will be between 85-95.

As the animal grows and develops its wingspan will be shorter than the average adult wing-span, which is about equal to an adult human's: that is, about six feet, measured with wings/ arms outstretched from the body, parallel to the ground.
