About Waist to Height Ratio (WHtR) Calculator

The waist-to-height ratio (WHtR) equals waist circumference divided by height (WHtR = waist / height). It is a simple screening indicator related to central adiposity and cardio-metabolic risk. Many public sources consider < 0.5 a broadly lower-risk zone for adults, with higher values indicating increased risk. Use alongside other indicators (e.g., BMI, body fat %, lipid/glucose panels).

How to measure

  • Height: Without shoes, stand straight against a wall or use a stadiometer.
  • Waist: Measure after a normal exhale at the navel level or the midpoint between the lowest rib and the iliac crest, without compressing the tape.

Quick context

  • Adults often cite bands near: <0.5 lower risk, 0.5–0.6 elevated, >0.6 higher risk. Thresholds vary by source and population.
  • Interpretation depends on body shape, age, and ethnicity; clinical evaluation is recommended for decisions.

Disclaimer: WHtR is a screening tool and not a diagnosis. For medical guidance, consult a clinician.

FAQ

  • How do I calculate WHtR? Divide your waist circumference by your height using the same units (e.g., cm/cm).
  • What is a healthy WHtR? Many adult references cite < 0.5 as a general lower-risk zone; interpretation depends on context and population.
  • Is WHtR better than BMI? They measure different things. WHtR reflects central fat distribution, while BMI is weight relative to height squared. Using both can give a fuller picture.
  • Do men and women have different cut-offs? Many adult sources use similar broad bands for both, but clinical context (age, ethnicity, risk factors) matters.
  • How often should I re-measure? Recheck after notable weight or waist changes, or every few weeks during an active program.
