Determine your body shape based on your measurements. Enter your shoulder, bust/chest, waist, and hip measurements to discover your body type.
Measure at the fullest point of each area. Shoulders: across the widest point. Bust/Chest: fullest point. Waist: narrowest point. Hips: fullest point.
| Shape | Characteristic |
|---|---|
| Hourglass | Bust ≈ Hips, narrow waist |
| Pear (Triangle) | Hips > Bust by 3.5+ cm |
| Inverted Triangle | Bust > Hips by 3.5+ cm |
| Rectangle | Bust, waist, hips similar |
| Diamond | Waist widest overall |
Ectomorph, mesomorph and endomorph describe build and muscularity, an idea that traces back to psychologist William Sheldon's work in the 1940s. Hourglass, pear and rectangle describe nothing but where four tape measurements fall relative to one another. This calculator does the second thing: you enter shoulders, bust or chest, waist and hips, and a fixed set of rules names a silhouette and reports waist-to-hip and shoulder-to-waist ratios. Neither system is a medical classification.
Take the page's starting values for women, in centimeters: shoulders 91, bust 89, waist 69, hips 94.
The page first works out differences: |bust − hips| = |89 − 94| = 5; bust − waist = 20; hips − waist = 25; hips − bust = 5.
It then tests rules in order and stops at the first match. Hourglass needs |bust − hips| ≤ 3.5, bust − waist ≥ 9 and hips − waist ≥ 10, and bottom or top hourglass relax that when hips or bust are slightly larger. Next come Pear if hips − bust > 3.5, Inverted Triangle if bust − hips > 3.5, Rectangle if bust and hips are within 3.5 and the waist is under 9 smaller, and Diamond if the waist is the largest. For men only shoulders ÷ waist counts: 1.35 or more is V-shape, 1.20 or more Trapezoid, 1.05 to under 1.20 Rectangle, and a waist larger than the shoulders Oval.
In the example, 5 is not ≤ 3.5, so no hourglass variant applies, and hips − bust = 5 is above 3.5, so the answer is Pear (Triangle). Shoulders played no part in that decision; for women they only feed the shoulder-to-waist ratio.
The ratios: waist ÷ hips = 69 ÷ 94 = 0.73, which the page tags Low risk, and shoulders ÷ waist = 91 ÷ 69 = 1.32, tagged Fit. The page's risk bands are below 0.80 low and below 0.85 moderate for women, and below 0.90 and below 1.00 for men. The WHO's 2008 expert consultation on waist circumference and waist-hip ratio uses 0.85 for women and 0.90 for men as thresholds for substantially increased health risk, so treat the page's wording as rough, especially for men, and ask a doctor what a ratio means for you.
The cut-offs of 3.5, 9 and 10 are fixed numbers applied in whichever unit you pick, not converted. The page's own sample values illustrate it: the centimeter defaults return Pear while the inch defaults return Bottom Hourglass. Compare both and weigh the ratios more than the label.
No. Somatotypes are a loose descriptive idea about build and muscularity, while this page sorts circumference ratios into silhouettes. Neither is a medical classification.
Pear, Inverted Triangle and Rectangle are tested first, so a larger waist usually lands on one of those. Diamond only surfaces in a narrow case, when bust and hips differ by exactly 3.5. Read the label loosely.
Shape alone does not. Only the waist-to-hip ratio has health associations, per the WHO report, and even that is a screening signal and not a diagnosis. Where the body carries weight is one factor among many, so speak with a doctor about any concerns.
Only shoulders and waist. Chest and hips are collected but do not affect the label, which depends on the shoulder-to-waist ratio and whether the waist exceeds the shoulders.
