Waist circumference and metabolic health

Assessment · 1 min · free · no data stored

Measure your waist circumference and see how it compares with public health benchmarks. Educational tool: it does not diagnose anything and does not directly measure abdominal fat.

Result preview

Example: Male, height 175 cm, waist 96 cm → Watch range (WHtR 0.55)

Sex used for the thresholds

Your height, between 130 and 230 cm.

Waist measurement, between 50 and 200 cm.

To activate the button: confirm you are an adult ; enter your height ; enter your waist circumference.

What this tool gives you

This tool places your waist measurement against the cardiometabolic risk thresholds used in clinical practice and explains why it complements BMI: it reflects abdominal fat, which is more closely linked to insulin resistance and cardiovascular risk.

You learn how to measure correctly, how to read the result in your own context (age, sex, family history, blood pressure, lipid profile) and which dietary levers matter first.

The result is indicative and is neither a diagnosis nor medical advice.

Frequently asked questions

Where do I place the tape measure?
Midway between the lowest rib and the top of the iliac crest, at the end of a normal breath out, without compressing the skin.
Does waist size replace BMI?
No, it complements it. Both are read alongside medical history and blood results.
What if the result is high?
Discuss it with your doctor and consider a nutrition assessment; dietetic treatment can be prescribed for the indications covered by the CNS convention.
Method and sources

The thresholds used are those of the IDF and the WHO for adults of European origin:

  • Women — reference < 80 cm; alert ≥ 88 cm
  • Men — reference < 94 cm; alert ≥ 102 cm
  • Waist-to-height ratio (WHtR): reference < 0.5; alert ≥ 0.6

Waist circumference is an indirect indicator of cardiometabolic risk, statistically correlated with abdominal fat mass without directly measuring it.

Sources: IDF, The IDF consensus worldwide definition of the metabolic syndrome, 2006; WHO, Waist Circumference and Waist-Hip Ratio, 2008; Ashwell M. et al., Obesity Reviews, 2012 (WHtR).

Clinical methodology: the thresholds are those set by international learned societies for cardiometabolic risk, applied within conventioned dietetic practice in Luxembourg (CNS–ANDL convention).
