Waist–hip ratio
WHR is used as a measurement of obesity, which in turn is a possible indicator of other more serious health conditions. The WHO states that abdominal obesity is defined as a waist-hip ratio above 0.90 for males and above 0.85 for females, or a body mass index (BMI) above 30.0. The National Institute of Diabetes, Digestive and Kidney Diseases (NIDDK) states that women with waist-hip ratios of more than 0.8, and men with more than 1.0, are at increased health risk because of their fat distribution.

Variations include the height of the person's torso (known as "back length"), whether the bust, waist, and hips are straighter (characteristic of teenagers) or curvier (like many adult women), and whether the bust is higher or lower (characteristic of younger and older women, respectively). These categories include:Please compare to your favorite fit charts. These measurements conflict with many other size charts. These charts are significantly smaller than many current US clothing companies.
