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.
Waist–hip ratio
Some researchers have found that the waist–hip ratio is a significant measure of female attractiveness. Women with a 0.7 WHR are usually rated as more attractive by men from Indo-European cultures. Preferences may vary, according to some studies, ranging from 0.6 in China, South America, and some of Africa to 0.8 in Cameroon and among the Hadza tribe of Tanzania, with divergent preferences according to the ethnicity of the observed being noted.
