Free body shape calculator: find your body type (hourglass, pear, apple, rectangle or inverted triangle) from bust, waist and hip measurements.
Body shape is determined by the proportions between your bust, waist, and hip measurements — not just your weight or size. Two people with the same height and weight can have completely different body shapes depending on where their body stores fat and muscle. Understanding your body shape helps with clothing fit, style choices, and health awareness.
The calculator classifies your body into one of five types based on internationally recognized measurement ratios: Hourglass (balanced bust and hips with a defined waist), Pear (hips wider than bust), Apple (waist close to or larger than hips), Inverted Triangle (bust wider than hips), and Rectangle (all three measurements similar).
How to measure: Use a soft measuring tape against bare skin or light clothing. Stand straight with feet together. Measure your bust at the fullest point, waist at the narrowest point above the navel, and hips at the widest point across your buttocks. Keep the tape level, snug but not tight. Take each measurement 2–3 times and use the average.
In addition to body shape classification, this calculator shows your waist-to-hip ratio (WHR) — an independent health indicator used by the World Health Organization. A lower WHR (below 0.80 for women) is associated with lower cardiovascular risk. If you enter your height, the calculator also shows your waist-to-height ratio (WHtR) — a health metric supported by the 2024 Lancet Regional Health study as a strong predictor of cardiovascular risk. The simple rule: keep your waist less than half your height.
Body shape is determined by comparing your bust, waist, and hip measurements using ratios. A waist-to-hip ratio (WHR) below 0.78 with balanced bust and hips indicates an hourglass shape. WHR above 0.85 suggests an apple shape (more weight around the midsection). Hips larger than bust by over 5% indicates a pear shape. Bust larger than hips by over 5% indicates an inverted triangle. If all three measurements are similar, you have a rectangle shape.
Waist-to-hip ratio (WHR) is an important health indicator because it reflects where your body stores fat. Abdominal fat (apple shape, high WHR) is more strongly linked to cardiovascular disease, type 2 diabetes, and metabolic syndrome than fat stored on the hips and thighs (pear shape). For women, a WHR below 0.80 is considered low risk, 0.81–0.85 is moderate risk, and above 0.85 is high risk according to WHO guidelines. WHR is a better predictor of health risk than BMI alone.
Yes, body shape can change significantly with weight loss, muscle gain, and aging. As you lose weight, different areas change at different rates — your waist might slim before your hips, potentially changing your body shape classification. Building muscle in specific areas can also shift your ratios. A healthy diet, cardiovascular exercise, and strength training are effective ways to improve body composition. Track your waist-to-height ratio (WHtR) alongside WHR — a decreasing WHtR is a reliable sign of improving metabolic health. Re-measure every 4–6 weeks to monitor progress.
Measure with a soft tape against bare skin: waist at the narrowest point above the navel, hips at the widest point across the buttocks, and bust at the fullest point. Take each measurement 2-3 times and use the average.
Body shape itself is not a diagnosis, but where you store fat matters. A higher waist-to-hip ratio (apple pattern) is linked to higher cardiovascular and metabolic risk, which is why WHR is used as a screening indicator.
The five shapes describe clothing fit for any body. The health thresholds in this calculator use female WHR cutoffs (WHO); for men, the corresponding cutoffs are roughly 0.90-0.95. Treat the health labels as general guidance.
