The waist to height ratio (WHtR) calculator is a measure of your body fat distribution.
The higher your WHtR is, the higher the risk of obesity-related cardiovascular diseases such as heart attack, stroke or death. The value should be less than 50% in healthy adults. To achieve this your waist circumference should be less than half of your height.
To measure your waist, take the measurement just above the belly botton using a stretch-resistant tape measure.
WHtR Range Classification for Men, Women and Children (<= 15 years)
To calculate your WHtR manually, simply divide your waist circumference (cm) by your height (cm) and multiply by 100.
Then compare your ratio with the table below:
| WHtR Classification | Adult Women | Adult Men | Children <= 15 years |
|---|---|---|---|
| Extremely Slim | <= 34% | <= 34% | <= 34% |
| Slim | 35-41% | 35-42% | 35-45% |
| Healthy | 42-48% | 43-52% | 46-51% |
| Overweight | 49-53% | 53-57% | 52-63% |
| Very Overweight | 54-57% | 58-62% | >= 64% |
| Morbidly Obese | >= 58% | >= 63% | - |
More Reliable than BMI
Studies have shown that WHtR is a more accurate indicator of cardiovascular, diabetes and stroke risk than body mass index (BMI) because it takes into account abdominal fat. Abdominal fat affects your body more adversely than fat around the hips and bottom.
