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 proportions
Another common measurement of related to leg-to-body ratio is sitting-height ratio (SHR). Sitting height ratio is the ratio of the head plus spine length to total height which is highly correlated to leg-to-body ratio. SHR has been found to be very different between individuals of different ancestry. It has been reported that individuals with African ancestry have on average longer leg length, i.e. lower SHR than individuals of European ancestry. A study in 2015 revealed that this difference is mainly due to genetic differences and the SHR difference between African and European individuals is as large as 1 standard deviation.
