Formula Used
Waist-to-Height Ratio (WHtR) is defined as waist / height, with waist and height measured in the same units. A commonly cited general target is to keep waist ≤ 0.5 × height for many adults. This calculator provides multiple scenarios around that reference.
- Target waist =
ratio × height(e.g., 0.50 × 172 cm = 86 cm). - Bands (simplified): < 0.40 very lean; 0.40–0.49 healthy; 0.50–0.59 increased risk; ≥ 0.60 high risk.
- These thresholds are population-level heuristics and not individual diagnosis.
How to Use
- Enter your height and choose centimeters or inches.
- Optionally select sex to tailor contextual notes only.
- Review suggested scenarios at WHtR 0.45, 0.50, and 0.53.
- Add a custom ratio if you have a different target.
- Download results as CSV or a print-ready PDF for records.

FAQs
No. WHtR thresholds summarize population risk. Genetics, age, ethnicity, fat distribution, and health conditions matter. Discuss personalized targets with a qualified clinician who knows your history.
Measure height without shoes, standing tall. For waist, measure at the midpoint between your lowest rib and the top of the hip bone after a relaxed exhale. Keep the tape snug, not tight.
Some groups reference slightly different “healthy” ranges by sex. This tool centers the widely used WHtR concept and lets you explore nearby ratios instead of prescribing a single number.
Children, adolescents, and elite athletes can differ markedly from adult reference bands. Seek age- and sport-specific guidance for meaningful interpretation of waist measures.
