What Are the Main Body Shape Types?
Body shape type refers to the general distribution of mass and proportions across the body — primarily determined by the relative sizes of the shoulders/chest, waist, and hips. While individual bodies exist on a continuous spectrum, five commonly recognised categories help describe the main patterns of fat and muscle distribution. Understanding your body shape provides health context that BMI alone cannot capture — particularly regarding where fat is stored and the associated health risks.
The five main types — apple, pear, hourglass, rectangle (or banana), and inverted triangle (or strawberry) — are determined primarily by measurement proportions and partly by skeletal structure and genetics. They are most clinically useful not as fashion categories but as indicators of fat distribution pattern, which is a strong independent predictor of cardiometabolic health risk above and beyond total body weight or BMI. For your BMI alongside body shape, use our NHS Healthy BMI Range Calculator and Visual BMI Calculator.

The Five Body Shape Types: A Complete Guide
🍎 Apple Body Shape (Android Fat Distribution)
The apple shape is characterised by: a relatively large bust/chest and midsection; a waist that is not significantly narrower than the hips or bust; and comparatively narrower hips and legs relative to the upper body. Weight tends to be carried around the abdomen and torso. This is more common in men (which is why it is also called "android" distribution) but affects women too, particularly post-menopause as oestrogen levels decline.
Health risk: The apple shape carries the highest cardiometabolic risk of all body shape types. This is because abdominal fat — particularly visceral fat that surrounds internal organs — is metabolically active and strongly associated with: insulin resistance and type 2 diabetes; elevated triglycerides and LDL cholesterol; high blood pressure (monitor with our Blood Pressure Calculator NHS); metabolic syndrome; and elevated cardiovascular risk (check with our QRISK Calculator NHS). The NHS uses waist circumference (above 94cm for men, 88cm for women) as a clinical indicator of this elevated risk, independent of BMI.
🍐 Pear Body Shape (Gynoid Fat Distribution)
The pear shape is characterised by: shoulders and bust narrower than the hips; a well-defined waist that is significantly narrower than the hips; and notably wider hips, thighs, and buttocks. Weight is concentrated in the lower body. This pattern is more common in women (hence the alternative name "gynoid distribution") and is influenced by oestrogen, which promotes fat deposition in the hip and thigh area.
Health risk: Pear shapes carry lower cardiometabolic risk than apple shapes, even at equivalent BMI. Fat stored in the hips and thighs (subcutaneous fat) is metabolically less active than visceral abdominal fat. However, pear-shaped individuals are not immune to health risks from excess weight — they still experience increased risk at overweight and obese BMI categories. Pear shape may be associated with higher risk of joint problems in the knees and hips due to fat distribution in those areas.
⌛ Hourglass Body Shape
The hourglass shape is characterised by: bust and hips of approximately equal width (within 5cm); a clearly defined waist that is substantially narrower than both bust and hips (typically 25–30cm or more narrower); and proportional upper and lower body. This is often considered the most "proportioned" shape from a symmetry perspective and represents balanced fat distribution between upper and lower body.
Health risk: The hourglass shape typically carries the lowest cardiometabolic risk among body shapes at equivalent weight and BMI, because neither abdominal nor lower-body fat dominates. However, hourglass-shaped individuals can still be overweight or obese (BMI 25+), and excess weight at any distribution pattern raises health risk above a healthy BMI.
📦 Rectangle Body Shape (Banana / Athletic)
The rectangle (or banana) shape is characterised by: shoulders, waist, and hips of approximately equal width (all within 5cm of each other); little waist definition; and a relatively uniform silhouette. This shape is common in athletes with high muscle mass and in people with naturally low body fat, but can also appear in individuals with uniform fat distribution.
Health risk: Moderate — similar to pear shape. Fat distribution is relatively uniform, avoiding the concentrated abdominal visceral fat characteristic of apple shapes. Health risk is most influenced by total body weight (BMI) and overall body fat percentage rather than fat distribution, as there is no particular concentration in high-risk areas.
🔺 Inverted Triangle Body Shape (Strawberry)
The inverted triangle (or strawberry) shape is characterised by: broad shoulders and/or bust clearly wider than the hips; a relatively straight or narrow torso tapering to narrower hips; and a waist-to-hip ratio where hips are narrower than or equal to bust. This shape is most common in men with significant upper body muscle development and in some women with broader shoulder frames.
Health risk: For muscular individuals, the inverted triangle with low body fat carries low health risk. However, if fat is concentrated in the upper body and chest area (rather than muscle), this can approach android/apple-type risk. The waist-to-hip ratio and waist circumference measurements remain the most clinically relevant indicators for this body type.
Waist-Hip Ratio: The Key Body Shape Health Metric
Waist-hip ratio (WHR) is the most clinically validated way to quantify body fat distribution and its associated health risk. It is calculated by dividing waist circumference by hip circumference. The NHS and World Health Organisation use the following risk thresholds:
| Sex | Low Risk WHR | Moderate Risk | High Risk |
|---|---|---|---|
| Female | Below 0.80 | 0.80–0.85 | Above 0.85 |
| Male | Below 0.90 | 0.90–1.0 | Above 1.0 |
WHR above threshold is a stronger predictor of cardiovascular disease risk than BMI alone in many studies, because it directly captures the ratio of abdominal fat (high risk) to hip fat (lower risk). An apple-shaped person with a normal BMI but elevated WHR is at higher cardiometabolic risk than a pear-shaped person with the same BMI but a lower WHR. See our General Health Weight Ratios tool for your complete waist, hip, and height ratio assessment.
Waist-to-Height Ratio: The Other Key Measure
Waist-to-height ratio (WHtR) = waist circumference ÷ height. A WHtR below 0.5 is generally considered lower risk regardless of sex; above 0.5 indicates elevated cardiometabolic risk. The memorable rule is: "keep your waist to less than half your height." WHtR is considered by some researchers to be a more sensitive cardiometabolic risk indicator than BMI because it accounts for body size while directly measuring abdominal adiposity.
Compare your WHtR with our General Health Weight Ratios tool alongside your BMI from our NHS BMI Calculator.
Body Shape and Health Monitoring
Understanding your body shape type provides context for health monitoring that goes beyond the scale. Here is how to use body shape awareness practically:
- Apple shape: Monitor waist circumference monthly alongside BMI. Aim below 94cm (men) or 80cm (women). Prioritise cardiovascular and blood glucose health monitoring. Target dietary changes that reduce abdominal fat specifically: reduce refined carbohydrates and added sugars, increase fibre and protein, engage in regular aerobic exercise.
- Pear shape: Monitor BMI and total body weight — lower-body fat is more stubborn but less metabolically harmful. Focus on overall healthy BMI range rather than specific fat redistribution. Lower-body resistance training builds muscle that improves body composition at equivalent weight.
- Hourglass: Standard BMI and waist monitoring is generally sufficient. Weight gain tends to be proportional — the health priority is maintaining BMI in the healthy range (18.5–24.9).
- Rectangle: Body fat percentage measurement is particularly useful for this shape, as BMI may underestimate fat percentage in those with low muscle mass. See our BMI vs body fat percentage guide.
- Inverted triangle: If muscular, BMI may overstate health risk — waist circumference is a more relevant metric. If not muscular, monitor abdominal fat distribution carefully.

Frequently Asked Questions
The five main body shape types are: Apple (android) — weight around the abdomen and chest, narrower hips; Pear (gynoid) — wider hips and thighs, narrower shoulders; Hourglass — balanced bust and hips with a defined narrow waist; Rectangle (banana) — shoulders, waist, and hips of similar width with little waist definition; Inverted Triangle (strawberry) — broad shoulders tapering to narrower hips. Use the calculator above to identify your type from just three measurements.
The apple body shape (android distribution) carries the highest cardiometabolic health risk, regardless of BMI. Apple shapes store disproportionate visceral fat around the abdomen, which is strongly associated with type 2 diabetes, cardiovascular disease, high blood pressure, and metabolic syndrome. The NHS uses waist circumference (above 94cm for men, 88cm for women) as a clinical risk indicator. Monitor with our Blood Pressure Calculator NHS and QRISK Calculator NHS.
Measure three areas in centimetres: bust/chest (at the fullest point), waist (at the narrowest point, usually around navel height), and hips (at the widest point around the hip/buttock area). Use the calculator at the top of this page for automatic classification with NHS health risk assessment. Also measure height for waist-to-height ratio using our General Health Weight Ratios tool.
Yes — pear shapes generally have lower cardiometabolic risk than apple shapes at equivalent BMI. Fat in the hips, thighs, and buttocks (subcutaneous gynoid fat) is metabolically less active and less harmful than visceral abdominal fat. However, pear shapes are not risk-free — excess weight at any distribution pattern raises health risk above a healthy BMI. Both shapes benefit from maintaining BMI in the healthy range (18.5–24.9) and regular health monitoring.
The NHS and WHO recommend a WHR below 0.85 for women and below 0.90 for men as lower risk. Above 0.85 (women) or 1.0 (men) indicates abdominal obesity and elevated risk. WHR is calculated by dividing waist measurement by hip measurement. The calculator on this page calculates your WHR automatically. For more comprehensive body ratio assessment, use our General Health Weight Ratios tool.
The underlying skeletal proportions are genetic and fixed. However, fat distribution patterns — which significantly influence apparent body shape — can be modified. People who lose significant abdominal fat (apple shapes) can shift their proportions meaningfully, and resistance training can alter perceived body proportions by building muscle in specific areas. The health-relevant element of body shape — waist-to-hip ratio — is modifiable through lifestyle. See our BMI Transformation Guide and safe calorie deficit guide.
Waist-to-height ratio (WHtR) = waist ÷ height. A WHtR below 0.5 indicates lower cardiometabolic risk; above 0.5 indicates increased risk regardless of body shape or BMI. The memorable guideline is: "keep your waist to less than half your height." WHtR is particularly useful for apple-shaped individuals and is considered by some researchers to be a more sensitive risk indicator than BMI. Use our General Health Weight Ratios tool to calculate both WHtR and WHR together.
