Find your body shape and waist ratios from your measurements.
Compare bust, waist and hips. With a 96 cm bust, 70 cm waist and 98 cm hips you have an Hourglass shape and a waist-to-hip ratio near 0.71.
Body shape groups — apple, pear, hourglass, rectangle and inverted triangle — describe where your body carries its proportions. Enter your bust or chest, waist and hip measurements and your height to get your shape plus two health-related ratios: waist-to-hip and waist-to-height.
Shapes are descriptive, not medical. The ratios are more useful for health: fat carried around the waist is linked to higher risk of heart disease and diabetes than fat on the hips. See the BMI Calculator, Body Fat Calculator and Bra Size Calculator.
The calculator applies the standard published formulas step by step.

Apple, pear, hourglass, rectangle and inverted triangle. They describe the proportions of bust, waist and hips.
The WHO uses under 0.85 for women and under 0.90 for men as lower-risk values.
Keeping your waist under half your height (a ratio below 0.5) is a widely used guide.
Carrying fat around the middle is linked with higher metabolic risk, but shape alone does not decide your health.
Fat distribution is partly genetic and changes with age and hormones; exercise and weight change can shift proportions.
Use a soft tape, keep it level and snug but not tight, and measure in light clothing.
It uses the published formula: WHR = waist ÷ hip WHtR = waist ÷ height The full method and a worked example are shown on this page.
