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.
Body shape
Classifications of female body sizes are mainly based on the circumference of the bust-waist-hip (BWH), as in 36–24–36 (inches) respectively. In this case, the waist-hip ratio is 24/36 = 0.67. Many terms or classifications are used to describe body shape types:
