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.
Bust/waist/hip measurements
Breast volume will have an effect on the perception of a woman's figure even when bust/waist/hip measurements are nominally the same. Brassiere band size is measured below the breasts, not at the bust. A woman with measurements of 37A–27–38 will have a different presentation than a woman with measurements of 35C–27–38. These women have ribcage circumferences differing by 2 inches, but when breast tissue is included the measurements are the same. The result is that the latter woman will appear "bustier" than the former due to the apparent difference in bust to hip ratios (narrower shoulders, more prominent breasts) even though they are both technically 38–27–38.
