The Body Shape Calculator classifies your body shape — apple, pear, hourglass, rectangle, or inverted triangle — based on your measurements at the bust, waist, and hips. Body shape is more than cosmetic; different fat distribution patterns carry different metabolic implications. Apple-shaped bodies (fat concentrated at the waist) are associated with higher cardiovascular and metabolic risk compared to pear shapes (fat in the hips and thighs).
How to Use This Calculator
- Measure your bust at the fullest point across the chest.
- Measure your waist at the narrowest point, usually 1 inch above the navel.
- Measure your hips at the fullest point around the buttocks.
- Enter all three measurements in centimeters or inches.
- Click Calculate to see your body shape classification and health context.
What This Calculator Measures
This calculator classifies your body shape from bust, waist, and hip proportions.
- Apple (round): Waist ≥ bust and waist ≥ hips; highest metabolic risk category.
- Pear (triangle): Hips significantly wider than bust and waist; lower cardiovascular risk.
- Hourglass: Bust and hips roughly equal, waist significantly smaller; balanced fat distribution.
- Rectangle (straight): Bust, waist, and hips within a narrow range of each other.
- Inverted triangle: Bust notably wider than hips; common in athletes with developed upper bodies.
Formula or Logic
Waist-to-hip ratio (WHR) and waist-to-bust ratio (WBR) drive classification. Apple: WHR > 0.85 (women) or > 0.90 (men) with prominent waist vs. hips. Pear: Hips > Bust by ≥ 5%, Waist < Hips by ≥ 10%. Hourglass: (Bust + Hips) / 2 − Waist ≥ 25 cm and |Bust − Hips| < 5%. Rectangle: All three within 5% of each other.
Example Calculations
Example 1: Bust 90 cm, Waist 70 cm, Hips 95 cm. Hip-to-bust difference is 5.5%; waist deficit is 26% below hips → Hourglass classification.
Example 2: Bust 92 cm, Waist 90 cm, Hips 93 cm. All measurements within 1–2% of each other → Rectangle classification.
Understanding Your Results
Body shape reflects genetic fat distribution tendencies and is not a direct measure of health. However, the apple shape correlates with visceral fat accumulation, which drives inflammation, insulin resistance, and cardiovascular risk. Diet and exercise can reduce waist circumference regardless of genetic body shape.
Common Mistakes to Avoid
- Measuring over clothing, which gives inaccurate circumference values.
- Taking only one measurement — body shape can shift significantly with even 5–10 kg of weight change.
- Treating body shape as fixed — lifestyle changes, particularly core-focused exercise and diet, alter shape over time.
- Using body shape classification to make dietary decisions without considering other health markers.
