Waist-to-hip ratio

0.85

WHO reading
Below 0.9

≈Estimate based on the stated model and assumptions

Notes for this result

  • This is a population-level estimate for adults, not a diagnosis. Discuss health decisions with a qualified professional.
  • Cut-offs from the WHO Expert Consultation on waist circumference and waist–hip ratio (2008).

What this calculator does

Waist-to-hip ratio reflects fat distribution; fat stored around the abdomen is associated with higher metabolic risk.

Formula and method

WHR = waist circumference ÷ hip circumference

Worked example

Calculated by this tool with its default inputs:

Inputs

  • Sex (cut-offs differ): Male
  • Waist circumference (any unit): 85 cm / in (see Units)
  • Hip circumference (same unit): 100 cm / in (see Units)

Results

  • Waist-to-hip ratio: 0.85
  • WHO reading: Below 0.9

How to read the results

WHO cut-offs for substantially increased risk: 0.90 or more for men, 0.85 or more for women.

Assumptions and limitations

  • An estimate for healthy adults, not a diagnosis or medical advice. Consult a qualified health professional about your personal situation.

Health results are general estimates for adults and do not replace medical advice, diagnosis or treatment. Speak to a qualified health professional about your personal situation, especially during pregnancy or if you have a medical condition.

Questions

Is WHR better than BMI?

They measure different things; using both gives a fuller picture.
