What is a Cephalic Index?
A cephalic index (CI) is a measure of the width of a person’s head, specifically the width of the head at its widest point (the cephalic diameter) divided by the length of the head from the front of the skull to the back (the occipital diameter). A cephalic index of 80 means that the head is 80% as wide as it is long.
Range of Cephalic index
The cephalic index (CI) is a measure of the width of a person’s head, relative to its length. It is calculated by dividing the width of the head by the length of the head.
Historic and Modern Use Cephalic Index
The cephalic index is a measure of the width of a person’s head, relative to the length. It is determined by measuring the width of the head at its widest point and dividing that number by the length of the head from front to back. A cephalic index of 80, for example, would mean that the head is 80% as wide as it is long.
The cephalic index has been used for centuries to measure the width of a person’s head. It was first used by ancient Greeks and Romans to determine the ideal head shape for statues. In the early 20th century, it was used by anthropologists to study the differences in head shape between different races. Today, it is used by plastic surgeons to determine the best shape for a person’s skull when they are considering surgery.
The cephalic index is not a perfect measure of a person’s head shape. It can be affected by a person’s hair style, hat, and other factors. However, it is a useful measure of the width of a person’s head and can be used to compare different populations or to determine the best shape for a person’s skull.
