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.

Additionally, a study of "Seventeen magazine" concluded that the models featured in this popular teen magazine were far less curvy than those portrayed in women's magazines. It was also noted that the hip-to-waist ratio had decreased in these models from 1970 to 1990.
