Body Type Calculator
Identify your female body shape from bust, waist and hip measurements.
About Body Type Calculator
Body shape is determined by the relative proportions of bust, waist and hips. The classification maps these ratios to seven recognised shapes. The waist-to-hip ratio is the primary driver: a waist significantly narrower than hips produces hourglass or pear shapes; similar measurements produce a rectangle; a wide shoulder-to-hip differential produces an inverted triangle. Because every output is a ratio, the result is the same whether you measure in centimetres or inches — just pick one unit and use it for all three measurements.
Formula
Waist-to-hip ratio
WHR = Waist circumference ÷ Hip circumference

Assumptions and limits
- The result is derived only from the 7 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
- Body shape classification is based on proportion ratios and is a screening tool only. It does not constitute a medical assessment or dietary advice. Body shape is one factor among many that influence health risk.
- This is an estimate for general information and not professional medical advice. See the full disclaimer for the limits that apply to this kind of calculator.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions
Does body shape have health implications?
Yes — waist-to-hip ratio is a validated predictor of cardiovascular and metabolic risk, independent of BMI. A higher WHR (fat stored around the abdomen) is associated with greater risk than fat stored in the hips and thighs. The WHO risk cutpoints are WHR > 0.90 for men and > 0.85 for women.
Can body shape change?
Yes. Significant fat loss or gain changes the proportions of waist and hips. Resistance training can increase shoulder and hip width relative to waist. Hormonal changes (menopause, PCOS) can redistribute fat from hips to abdomen.
How accurately should I measure?
Use a soft tape measure against skin, without pulling tight. Measure at the same time of day (waist circumference varies by several centimetres depending on meals and bloating). Average two consecutive readings if you want more precision.
