Body Type Calculator

About the Body Type Calculator

A body type calculator classifies your body shape — apple, pear, hourglass, rectangle, or inverted triangle — from waist, hip, bust, and shoulder measurements, and calculates your waist-to-hip ratio (WHR) as a health marker. Body shape reflects fat distribution patterns, which are influenced by genetics, hormones, age, and lifestyle. The waist-to-hip ratio is the primary clinical metric: WHO guidelines classify WHR above 0.85 (women) or 0.90 (men) as indicating abdominal obesity, which is independently associated with increased cardiovascular disease, type 2 diabetes, and metabolic syndrome risk — regardless of BMI. Body shape terminology (apple, pear, hourglass) is widely used in fashion and fitness; the geometric classification helps with clothing fit, workout programme design, and understanding where the body stores fat. Our calculator uses WHR plus relative proportions of bust, waist, and hip (with optional shoulder width) to classify body type with nuance beyond just the WHR ratio. Relevant for anyone interested in fitness, health, or clothing fit, across all countries.

How It Works

Waist-to-hip ratio (WHR) = waist circumference / hip circumference. Female classification: WHR < 0.75 = low risk; 0.75-0.85 = moderate risk; > 0.85 = high risk (WHO). Male: < 0.90 = low; 0.90-1.0 = moderate; > 1.0 = high. Body shape (women): Hourglass: bust and hip within ~3.5 cm, WHR < 0.75; Pear (Triangle): hips > bust by > 3.5 cm, WHR < 0.80; Inverted Triangle: bust > hips by > 3.5 cm; Apple: WHR ≥ 0.85 with midsection wider; Rectangle: all measurements within ~3.5 cm of each other. Body shape (men): V-shape: WHR < 0.85; Rectangle: WHR 0.85-0.95; Apple: WHR > 0.95. Example: bust = 36", waist = 27", hips = 38". WHR = 27/38 = 0.71. Bust−hip = 36−38 = −2 (hips wider). Hourglass (bust−hip within 3.5" and WHR < 0.75). ✓

Tips & Best Practices

• ✓Measure waist at the narrowest point, typically about 1 inch above the navel — not at the belt line. Measure hips at the widest point across the buttocks. Stand naturally, breathe normally, and do not suck in. Take measurements in the morning before eating for consistency.
• ✓Waist-to-hip ratio is a better predictor of cardiovascular risk than BMI alone, particularly for individuals with normal BMI but central fat distribution (the "skinny fat" or TOFI — thin outside, fat inside — phenomenon). Adding waist circumference to BMI significantly improves cardiovascular risk prediction.
• ✓Body fat distribution is heavily influenced by hormones. Oestrogen promotes hip and thigh fat storage (pear shape); testosterone promotes upper body muscle mass (V-shape); cortisol and insulin resistance promote abdominal fat (apple shape). Post-menopausal women often transition from pear to apple as oestrogen levels fall.
• ✓Clothing fit by body type: Pear shapes benefit from A-line skirts and wide-leg trousers that balance hip width; Apple shapes from empire waistlines and wrap styles that define the bust and minimise the midsection; Hourglass from fitted styles that follow the natural waist; Rectangle from layered and belted styles that create waist definition.
