The waist-to-hip ratio calculator divides waist by hip (cm) and shows sex-specific risk bands for fat distribution screening.
How to use
- Choose sex (cutoffs differ).
- Enter waist and hip in cm measured consistently.
- Read ratio and band; add context with BMI and body fat.
Example
Male, 80 cm waist, 95 cm hips → ratio ~0.84, low band (rounded).
Screening only—not diagnosis or treatment.
Frequently asked questions
What is waist-to-hip ratio?
Waist ÷ hip (same units—cm here). It describes central vs hip fat distribution, used in screening; this page shows low / moderate / high bands.
How to measure waist?
Usually at navel level, end of a normal exhale, tape snug not tight. Measure consistently for comparable trends.
How to measure hips?
At the widest part of the hips, level tape. Use the same unit as waist (cm).
Why sex-specific cutoffs?
Cutoffs differ by sex, matching common epidemiology tables. Pick the option that matches your context—screening only, not a diagnosis.
Vs BMI and body fat?
BMI is weight-for-height; WHR is distribution. Pair with BMI and body fat for context—no single number replaces a checkup.
If my ratio is high?
Talk to a clinician or dietitian about lifestyle and follow-up. For planning-level intake ideas, see the calorie deficit calculator—not medical advice here.
Can I save my measurements?
Yes. Copy link below the form keeps your current inputs so you can share the scenario or save it for later.
