Where do I measure my waist?
Usually at the narrowest point between ribs and hips, or at navel level—stay consistent each time.
Waist-to-Hip Ratio Calculator
Measure waist and hip circumference to get your waist-to-hip ratio and a simple risk category.

Use the same unit system for both measurements. Measure at the narrowest waist and widest hip.
About this calculator
How to use Waist-to-Hip Ratio Calculator, plus the formulas and logic behind the results.
Tool description
Waist-to-hip ratio compares central fat storage to hip size. Higher WHR often signals more abdominal fat, which is linked to metabolic risk in population studies.
How to use
- Select metric or US units.
- Choose sex for risk cutoffs.
- Enter waist and hip circumferences.
- Review WHR and the risk category shown.
Formulas & reference
WHR = waist ÷ hipUse consistent units (both cm or both inches)Risk cutoffs differ for men and women
Common WHR risk cutoffs
- Men low risk: below 0.90
- Men high risk: 0.95 and above
- Women low risk: below 0.80
- Women high risk: 0.85 and above
Calculation logic
Both measurements convert to cm internally, WHR is computed, then compared to sex-specific risk bands used in many clinical references.
Measure standing, relaxed, after normal exhale. Clothing thickness can skew results.
Waist-to-Hip Ratio Calculator FAQ
Common questions about this calculator and how to use the results.
Where do I measure my hips?
At the widest part of the buttocks, keeping the tape level.
Is WHR better than BMI?
They capture different things. WHR reflects fat distribution; BMI reflects weight relative to height.
Can WHR change quickly?
Waist can shift with bloating or training, but meaningful changes usually take weeks.
Do athletes get high WHR?
Very muscular builds can sometimes raise waist measures; context matters.
Should I worry about one reading?
Use WHR as a screening clue, not a diagnosis. Trends and other labs matter too.
