Measure your bust at its fullest point, waist at its narrowest, and hips at their widest — all with a relaxed, level tape measure.
Your Body Shape
Bust, waist, and hips are all similar in width, giving a straighter silhouette.
For general guidance only.Body shape is one of many ways to describe proportions — it isn't a health or fitness measure on its own.
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.
Why Use a Body Shape Calculator?
Clothing fit, styling advice, and even fitness goals are often discussed in terms of body shape, but figuring out your own shape from measurements alone can be confusing without a clear reference framework. This calculator automates that classification, turning three simple tape-measure readings into a clear, named category.
It's especially useful alongside the BMI Calculator for anyone wanting a fuller picture of their proportions rather than just an overall size figure, since two people with the same BMI can have very different body shapes.
Who Should Use This Calculator?
- Anyone shopping for clothing who wants to understand which styles typically flatter their proportions.
- People tracking body composition changes during a fitness or weight program who want to see shifts in shape, not just weight.
- Fitness and style coaches who reference body shape when giving personalized recommendations.
- Anyone curious about body shape terminology and how hourglass, pear, apple, rectangle, and inverted triangle shapes are actually defined.
- People comparing body shape with health-risk metrics like the Waist-to-Hip Ratio Calculator for a broader self-assessment.
What Insights Does the Body Shape Calculator Give You?
The calculator returns your body shape category alongside two supporting ratios:
- Body Shape, the primary result, one of five categories (Hourglass, Pear, Apple, Rectangle, or Inverted Triangle) based on your measurement proportions.
- Bust-to-Hip Ratio, shows how your bust and hip measurements compare, useful context for shapes like inverted triangle and pear.
- Waist-to-Hip Ratio, shows how defined your waist is relative to your hips, a key factor distinguishing hourglass and apple shapes.
Together, these figures explain not just which category you fall into, but why, which measurement relationships drove the classification.
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.
