How the body type calculator works
Body shape is judged from how your bust, waist, high hip and hips compare. The rules used here (from the widely used FFIT system by Simmons, Istook and Devarajan) sort measurements into hourglass, bottom hourglass, top hourglass, spoon, triangle, inverted triangle and rectangle.
Your waist-to-hip ratio is shown too. The WHO links a ratio above 0.85 in women (0.90 in men) with higher heart and metabolic risk.
