Body Shape Calculator
Discover your body silhouette type (Hourglass, Pear, Rectangle, Inverted Triangle, Apple) and analyze your Waist-to-Hip cardiovascular health ratio.
| Bust-to-Waist Ratio | 1.38 (Well-Defined) |
| Hip-to-Waist Ratio | 1.42 (Curvy Lower Body) |
| Bust vs Hip Balance | Balanced (Bust within 1 inch of Hips) |
| Key Styling Focus | Fitted silhouettes that accentuate natural waistline |
The 5 Primary Body Shape Silhouettes Explained
Fashion designers and anthropometrists classify human body proportions into five distinct geometric silhouettes based on the relationship between the bust, waist, and hips:
- Hourglass: Bust and hips are nearly equal in circumference, with a well-defined waist that is at least 25% narrower than both the bust and hips.
- Pear (Triangle): Hips are significantly wider than the bust and shoulders (hips are more than 5% larger than bust), with a gently defined waistline.
- Rectangle (Banana / Athletic): Bust, waist, and hips are fairly uniform in measurement (waist is less than 25% smaller than bust or hips), creating a sleek, straight athletic frame.
- Inverted Triangle (Apple Bottom): Bust and shoulders are noticeably broader than the hips (bust is more than 5% larger than hips).
- Apple (Round): Waist measurement is close to or larger than the bust and hips, with weight concentrated around the midsection and chest.
The Mathematics of Body Proportions
Here are the mathematical ratios used to classify body shapes and evaluate cardiovascular health:
Bust-to-Waist Ratio (BWR) = Bust Circumference / Waist Circumference
Hourglass Rule: (Bust - Hip ≤ 1 inch AND Hip - Bust < 3.6 inches) AND (Bust - Waist ≥ 9 inches OR Hip - Waist ≥ 10 inches)
Pear / Triangle Rule: (Hip - Bust ≥ 2 inches) AND (Hip - Waist ≥ 7 inches)
Inverted Triangle Rule: (Bust - Hip ≥ 2 inches)
Rectangle Rule: (Bust - Waist < 9 inches) AND (Hip - Waist < 10 inches)
Step-by-Step Worked Example
Suppose your measurements are Bust: 36 inches, Waist: 26 inches, Hips: 37 inches:
- Calculate WHR:
26 / 37 = 0.7027(Healthy Low Risk category). - Compare Bust and Hips:
|36 - 37| = 1 inch difference(Well-balanced top and bottom). - Check Waist Definition:
Bust - Waist = 10 inches; Hip - Waist = 11 inches(Both ≥ 9 inches). - Classification: Classic Hourglass Shape.

Summary of proportional characteristics and recommended wardrobe choices for each body type:
| Body Silhouette | Defining Proportions | WHR Profile | Flattering Clothing Styles |
|---|---|---|---|
| Hourglass | Balanced bust & hips, narrow waist | ≤ 0.75 (Defined) | Wrap dresses, high-waisted tailored pants, V-neck tops, belted coats |
| Pear (Triangle) | Hips wider than bust & shoulders | 0.70 to 0.80 | A-line skirts, boatneck tops, structured blazers, wide-leg trousers |
| Rectangle (Athletic) | Straight silhouette, subtle waist | 0.80 to 0.88 | Ruffled tops, fit-and-flare dresses, belted jackets, pleated skirts |
| Inverted Triangle | Broad shoulders, narrower hips | 0.75 to 0.85 | V-neck tops, flare jeans, peplum tops, printed pants, wrap tops |
| Apple (Round) | Fuller midsection, slim limbs | ≥ 0.85 | Empire waist dresses, flowy tunics, open-front cardigans, straight-leg pants |
Waist-to-Hip Ratio (WHR) Health Benchmarks
According to the World Health Organization (WHO), body fat distribution is a stronger predictor of cardiovascular disease, hypertension, and Type 2 diabetes than Body Mass Index (BMI) alone:
- Women:
- Low Health Risk: WHR of 0.80 or below
- Moderate Health Risk: WHR between 0.81 and 0.85
- High Health Risk: WHR of 0.86 or above
- Men:
- Low Health Risk: WHR of 0.90 or below
- Moderate Health Risk: WHR between 0.91 and 0.95
- High Health Risk: WHR of 0.96 or above
5 Tips for Taking Accurate Tape Measurements
Frequently Asked Questions
The five standard body shapes are: Hourglass (balanced bust and hips with a defined waist), Pear/Triangle (hips wider than bust), Rectangle/Banana (bust, waist, and hips of similar width), Inverted Triangle (bust or shoulders noticeably wider than hips), and Apple/Round (waist wider than bust and hips).
Your natural waist is the narrowest part of your torso, located between the bottom of your rib cage and the top of your hip bones (usually 1 to 2 inches above your navel). Bending sideways creates a natural crease at your exact waistline.
BMI only measures total body weight relative to height and cannot differentiate between muscle mass and fat. Waist-to-Hip Ratio specifically measures abdominal visceral fat, which is the fat most strongly linked to heart disease and metabolic syndrome.
A Spoon shape is a variation of the Pear body type where the hips are significantly wider than the bust (by 2+ inches) and the high hip measurement is larger than the bust, creating a distinct shelf or curve at the upper hips.
Yes. Developing your latissimus dorsi (back) and shoulder deltoids creates the visual illusion of a smaller waist, while squats, hip thrusts, and lunges build glute volume to enhance lower body curves.
