Facial width to height ratio

Facial width-to-height ratio (FWHR) is a facial metric that is calculated by dividing the bizygomatic width (distance between the left and right zygomatic bones) by the upper facial height (distance between the upper lip and the highest point of the eyebrows). This ratio is used in various fields such as psychology, anthropology, and forensic science to study the correlation between facial features and certain behavioral traits.

Calculation[edit | edit source]

The FWHR is calculated by measuring the horizontal distance between the left and right zygomatic bones (the widest point of the face) and dividing it by the vertical distance from the upper lip to the highest point of the eyebrows. This ratio is usually measured using a straight frontal photograph of the face.

Applications[edit | edit source]

The FWHR has been used in various studies to explore the correlation between facial features and certain behavioral traits. For example, in psychology, it has been suggested that a higher FWHR is associated with higher levels of aggression and dominance. In anthropology, the FWHR has been used to study the evolution of human facial features. In forensic science, the FWHR can be used to help identify individuals.

Criticism[edit | edit source]

Despite its wide use, the FWHR has been criticized for its lack of consistency and reliability. Some studies have found no significant correlation between FWHR and behavioral traits, while others have found contradictory results. Furthermore, the FWHR can be influenced by factors such as age, sex, and ethnicity, which can complicate its interpretation.
