Body Shape Calculator — Classify Your Figure
Enter your bust, waist, and hip circumferences to discover your body shape category — hourglass, pear, apple, rectangle, or inverted triangle — along with key proportion ratios.

Hips are noticeably wider than bust; waist is well-defined.
How does this calculator work?
Body shape is determined by comparing bust, waist, and hip circumferences. Hourglass: bust ≈ hips, waist ≥9 cm narrower. Pear: hips > bust by ≥5 cm. Apple: waist ≈ or exceeds hips. Inverted triangle: bust > hips by ≥5 cm. Rectangle: all three similar. Enter your measurements to see your category and proportion ratios.
Formula
How this is calculated
Body shape classifications compare the relative circumferences of three key zones — bust/chest, waist, and hips — to identify which silhouette best describes how proportions are distributed. The calculator measures the absolute difference between bust and hips to decide whether they are "balanced" (within 5 cm) or one is notably wider. It then checks whether the waist is at least 9 cm narrower than the broader of the two, which is the hallmark of the hourglass and pear shapes.
An apple shape is identified when the waist is close to or larger than both bust and hips, indicating central weight distribution. A pear occurs when hips exceed bust by more than 5 cm and the waist is well-defined. An inverted triangle is the mirror image: bust exceeds hips by more than 5 cm. If bust and hips are within 5 cm but the waist shows little definition (within 9 cm of the bust or hip), the shape is a rectangle.
This is a geometric classification only — not a medical assessment. Natural body shapes vary enormously by bone structure, muscle distribution, age and weight, and no single shape is healthier than another. The ratios and differences are styling and proportion guides commonly used in fashion.
Frequently asked questions
You need three circumferences measured horizontally with a flexible tape: bust at the fullest point, waist at the narrowest point, and hips at the widest point. All in the same unit (centimetres here). Breathe normally and do not pull the tape tight.
Yes. Weight gain or loss, muscle building, hormonal changes, age and pregnancy all shift where fat and muscle are distributed, so your shape category can change. The calculator reflects your current measurements at any point in time.
Health research finds that apple-shaped fat distribution (central adiposity) correlates with higher cardiovascular risk compared with pear-shaped fat distribution, but shape alone is not a diagnosis. Use the waist-to-hip ratio alongside BMI and body-fat percentage for a fuller picture.
