📐 Formula

Waist-to-Hip Ratio WHR = Waist Circumference ÷ Hip Circumference
Female Hourglass: (Bust - Hips ≤ 1") AND (Waist-to-Bust ratio ≤ 0.75)
Female Pear: (Hips - Bust ≥ 3.6") AND (Hips - Waist ≥ 9")

💡 Practical Example

✅

Bust 36", Waist 27", Hips 37": WHR = 27 / 37 = 0.73 (Low Cardiovascular Risk). Bust/Hip Difference = 1" | Hip/Waist Difference = 10". Classification = Hourglass (Balanced bust & hips with defined waist).

📖 About Body Type & Body Shape Calculator

Body shape is determined by skeletal structure and body fat distribution. In addition to aesthetic styling guidance, measuring your Waist-to-Hip Ratio (WHR) provides vital insight into visceral fat storage and cardiovascular health.

To use the Body Type & Body Shape Calculator, enter your Gender, Bust / Chest Circumference, Natural Waist Circumference and other values. The calculator instantly computes Body Shape Classification, Waist-to-Hip Ratio (WHR) and more. Results update in real time as you change any input — no submit button needed.

How to Use This Calculator

Enter your Gender — choose from Female, Male, Bust / Chest Circumference (e.g. 36 in inches), Natural Waist Circumference (e.g. 27 in inches), and Fullest Hip Circumference (e.g. 37 in inches). Results update instantly as you type — adjust any value to compare scenarios.

The Formula

Waist-to-Hip Ratio WHR = Waist Circumference ÷ Hip Circumference

Female Hourglass: (Bust - Hips ≤ 1") AND (Waist-to-Bust ratio ≤ 0.75)

Female Pear: (Hips - Bust ≥ 3.6") AND (Hips - Waist ≥ 9")

Worked Example

Bust 36", Waist 27", Hips 37":

WHR = 27 / 37 = 0.73 (Low Cardiovascular Risk).

Bust/Hip Difference = 1" | Hip/Waist Difference = 10".

Classification = Hourglass (Balanced bust & hips with defined waist).

Understanding Your Result

Evaluate your result in the context of your specific use case and relevant industry standards or reference values. A single calculated result is a starting point — test two to three scenarios to understand how sensitive the outcome is to your key input assumptions. For high-stakes decisions, verify your result against a secondary source or subject-matter expert before acting.

💡 Mathematical Rigor & Applied Context

  • This calculator applies exact mathematical definitions following conventions established by NIST and international standards bodies.
  • Rounding errors accumulate across multi-step calculations. For precision-critical work, maintain extra significant figures through all intermediate steps.
  • Many mathematical concepts have multiple valid formulations — if a result seems unexpected, verify which convention or definition applies to your context.
  • Dimensional analysis (unit tracking) is the fastest way to catch formula errors. Every term in an equation must have consistent, compatible units.
  • Numerical methods used in digital calculators introduce floating-point precision limits (~15 significant digits for IEEE 754 double precision).
  • For statistical and probabilistic calculations, always specify whether you are working with population parameters or sample statistics — formulas differ.
  • Visualizing a problem geometrically or testing with known boundary values (zero, infinity, negative) reveals hidden errors faster than algebraic checking.
  • When in doubt, validate your result against a simplified hand calculation or a published worked example from a textbook or standards document.
