Waist-to-Hip Ratio Calculator
When we talk about measuring health, the first thing that comes to mind is usually Body Mass Index (BMI). But there's another important metric that gives deeper insight into your risk of chronic diseases — the Waist-to-Hip Ratio (WHR).
In this post, we’ll explain what WHR is, how to calculate it, why units matter, and what your results might say about your health.
What Is Waist-to-Hip Ratio (WHR)?
WHR is a simple way to measure fat distribution in the body. It compares the size of your waist to that of your hips using the formula:
WHR = Waist circumference ÷ Hip circumference
This ratio helps determine if you're carrying more fat around your midsection — a key indicator for the risk of:
- Heart disease ❤️
- Type 2 diabetes 🩸
- Stroke 🧠
- Other metabolic disorders ⚠️
Which Units Should I Use — Inches or Centimeters?
The answer is simple: Either one works — as long as you're consistent.
- If you measure waist in inches, also measure hips in inches.
- If you measure waist in cm, also measure hips in cm.
Why? Because Waist-to-Hip Ratio is a unitless number — the units cancel out when you divide one by the other.
Correct Examples:
- 32 inches waist ÷ 40 inches hip = 0.80 ✅
- 81 cm waist ÷ 100 cm hip = 0.81 ✅
Wrong Example:
- 32 inches waist ÷ 100 cm hip = 0.32 ❌ (Totally inaccurate)

Quick Tips for Accurate Measurement
- Waist: Measure at the narrowest part, just above your belly button.
- Hip: Measure at the widest part of your buttocks.
- Stand up straight and relax your stomach — don’t suck in!
