Waist-to-Hip Ratio Calculator

Calculate your WHR to assess health risk from fat distribution

Formula

WHR = Waist Circumference ÷ Hip Circumference

Simple ratio of waist to hip measurement. Higher ratio indicates more abdominal (visceral) fat, which carries greater health risks.

How to Calculate Manually

1
Stand relaxed, feet together
2
Measure waist at narrowest point (above navel)
3
Measure hips at widest point of buttocks
4
Ensure tape is horizontal and snug
5
Divide waist by hip for ratio
6
Compare to risk categories for your sex

Reference Table

Risk Level	Men	Women	Health Implications
Low	< 0.90	< 0.80	Minimal cardiovascular risk
Moderate	0.90 - 0.99	0.80 - 0.84	Increased risk
High	0.90 - 0.99	≥ 0.85	Abdominal obesity
Very High	≥ 1.0	≥ 0.90	Substantial risk

Waist-to-Hip Ratio: Why Fat Distribution Matters More Than Weight

Where you store fat matters as much as how much you have. Visceral fat around your abdomen is metabolically active and releases inflammatory compounds that increase disease risk. The waist-to-hip ratio is a simple, powerful tool...

Frequently Asked Questions

How do I measure correctly? Waist: narrowest point (usually above navel). Hip: widest point of buttocks. Stand relaxed, breathe normally. Measure horizontally with tape snug but not compressing skin.: Waist: narrowest point (usually above navel). Hip: widest point of buttocks. Stand relaxed, breathe normally. Measure horizontally with tape snug but not compressing skin.
What's a healthy WHR? Men: <0.90 (low risk), 0.90-0.99 (moderate), ≥1.0 (high). Women: <0.80 (low risk), 0.80-0.84 (moderate), ≥0.85 (high). WHO defines abdominal obesity as ≥0.90 men / ≥0.85 women.: Men: <0.90 (low risk), 0.90-0.99 (moderate), ≥1.0 (high). Women: <0.80 (low risk), 0.80-0.84 (moderate), ≥0.85 (high). WHO defines abdominal obesity as ≥0.90 men / ≥0.85 women.
Why does WHR matter more than BMI? WHR indicates visceral fat (around organs), which is metabolically active and linked to heart disease, diabetes, and stroke. Two people with same BMI can have very different WHR and health risks.: WHR indicates visceral fat (around organs), which is metabolically active and linked to heart disease, diabetes, and stroke.
