What is a Body Shape?
A Body Shape Calculator classifies your figure into one of five standard categories — hourglass, pear, apple, rectangle, or inverted triangle — based on the relative proportions of your bust, waist, and hip measurements. Body shape is a widely used descriptive concept in fashion, fitness, and body image contexts, distinct from health-risk-focused metrics like the Waist-to-Hip Ratio Calculator, since it describes overall proportion rather than a single risk score.
This calculator takes your bust, waist, and hip circumference, compares the relationships between them, and returns your closest-matching body shape category along with the underlying bust-to-hip and waist-to-hip ratios.
How to use this Body Shape calculator
- Measure your bust at its fullest point and enter it as Bust / Chest Circumference in centimeters.
- Measure your waist at its narrowest point and enter it as Waist Circumference in centimeters.
- Measure your hips at their widest point and enter it as Hip Circumference in centimeters.
- Read your Body Shape result, shown as the primary classification.
- Review the Bust-to-Hip Ratio and Waist-to-Hip Ratio to understand which proportions drove your result.
- Check the step-by-step breakdown for the full reasoning behind your classification.
Formula & Methodology
Body shape is classified using proportional comparisons between three measurements: Bust-to-Hip Ratio = Bust ÷ Hip Waist-to-Hip Ratio = Waist ÷ Hip The calculator applies standard proportional rules: an Hourglass shape requires bust and hips within about 5% of each other with the waist at least 25% narrower than both; a Pear shape has hips at least 5% wider than the bust; an Inverted Triangle has a bust at least 5% wider than the hips; an Apple shape has a waist at least 80% as wide as both bust and hips; and a Rectangle shape applies when none of these proportional differences are pronounced. Worked example: for someone with a 90 cm bust, 75 cm waist, and 98 cm hips: - Bust-to-Hip Ratio = 90 ÷ 98 = 0.92 - Waist-to-Hip Ratio = 75 ÷ 98 = 0.77 - Hips are only slightly wider than the bust (not by 5%+), and the waist is meaningfully narrower than both — this proportion pattern classifies as Hourglass.
Frequently Asked Questions
A body shape calculator classifies your figure into a category — hourglass, pear, apple, rectangle, or inverted triangle — based on the relative proportions of your bust, waist, and hip measurements. It's a simple way to describe body proportions that's commonly used in fashion, fitness, and health contexts.
The five main categories are hourglass (bust and hips balanced with a defined waist), pear (hips wider than bust), inverted triangle (bust wider than hips), apple (waist close in width to bust and hips), and rectangle (bust, waist, and hips all similar in width). Each shape reflects a different pattern of how weight and proportions are distributed across the torso.
Waist-to-hip ratio, calculated by the [Waist-to-Hip Ratio Calculator](/waist-hip-ratio-calculator/), is a single number focused on health risk related to abdominal fat. Body shape classification uses three measurements — bust, waist, and hip — to describe overall figure proportions, which is a broader descriptive concept than a single risk ratio.
Measure your bust at its fullest point (typically across the nipple line), your waist at its narrowest point, and your hips at their widest point around the buttocks. Keep the tape measure level and snug but not tight for all three measurements.
Body shape itself is a descriptive classification, not a direct health measure, though research does suggest that abdominal fat concentration (more typical of an apple shape) is associated with higher cardiovascular risk than fat concentrated in the hips (more typical of a pear shape). For a specific health risk assessment, the [Waist-to-Hip Ratio Calculator](/waist-hip-ratio-calculator/) is more appropriate than body shape alone.
Yes — body shape can shift with changes in weight, muscle mass, and fat distribution, particularly around the waist and hips. Significant weight loss or gain, strength training, and hormonal changes (such as those during menopause) can all influence which category best describes your proportions.
BMI, from the [BMI Calculator](/bmi-calculator/), only measures overall size relative to height and says nothing about how weight is distributed across your body. Body shape classification specifically captures proportional differences between bust, waist, and hips that BMI cannot describe.
Research on body shape distribution varies by population and measurement methodology, but rectangle and pear shapes are frequently reported as common categories in general population studies. Hourglass, while often highlighted in media and fashion contexts, is statistically less common than these other shapes.
This calculator's bust, waist, and hip inputs and shape categories are most commonly associated with typical female body shape terminology, though the same three-measurement logic can technically be applied to any body. Men are often better served by chest-to-waist ratio tools focused on the inverted triangle or rectangle patterns most relevant to male body composition.
Body shape classification is inherently approximate since real bodies rarely fit perfectly into one of five discrete categories — many people fall close to a boundary between two shapes. This calculator uses standard proportional thresholds to make a best-fit classification, useful for general reference rather than precise clinical categorization.
Yes — body shape works well alongside the [Body Fat Calculator](/body-fat-calculator/) and [Ideal Weight Calculator](/ideal-weight-calculator/) for a fuller picture of body composition, since each tool measures a different aspect of size, proportion, or fat distribution.
