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.
Mate value
The Waist–hip ratio (WHR) of women is a feature that can be used to measure mate value. When males look for a long-term partner, they are looking for a healthy female with good reproductive value, and WHR is a good measure of both. There is also a strong preference for bigger breasts, as well as a low WHR when considering both short and long-term partners. When females look for potential male mates, they look at different features to men. It seems that averageness and texture of the face play an important part in attractiveness of men. When looking at short-term mates, male attractiveness is rated higher than when looking for long-term mates, where other factors such as resources and financial prospects are more highly valued.
