Waist–hip ratio
The waist-hip ratio or waist-to-hip ratio (WHR) is the dimensionless ratio of the circumference of the waist to that of the hips.
This is calculated as waist measurement divided by hip measurement (W ÷ H). For example, a person with a 30″ () waist and 38″ () hips has a waist-hip ratio of about 0.78.
Mating preferences
Like men, who have a preference for a lower waist-to-hip ratio (WHR), a measure linked to female bodily attractiveness, women tend to be more attracted to men who have broader shoulders and relatively narrow waists (the waist-to-chest ratio; WCR). The ratio, changed by the distribution of android fat in the torso, makes the characteristic V-shape and is related to levels of testosterone in males, also correlated with higher perceived dominance of males.
