There is no single official body-shape standard. This tool uses common rules of thumb based on proportions:
The World Health Organization (2008) uses a waist-to-hip ratio above 0.90 for men and 0.85 for women as a marker of substantially increased risk of metabolic complications. Waist-to-height ratio below 0.5 is another widely used screening cut-off.
Hourglass, pear (triangle), inverted triangle, rectangle and apple (round).
WHO uses 0.90 or less for men and 0.85 or less for women.
