WHtR Calculator (waist–height)
How to use this page
- Fill in the fields in the form above — the result recomputes at once, with no page reload.
- Under the result you will find the interpretation scale, if the calculator has one: it says which range your value fell into.
- The formula we use is shown lower on this page — you can check the arithmetic yourself.
- To compute the same for another game or variant, change it in the select field — prices and pools update automatically.
What this page does not do: It does not point to numbers to play and does not predict a draw — every draw is independent of the previous ones.

Interpretation scale
| Range | Description |
|---|---|
| below 0.4 | waist circumference below the typical range ← your result |
| 0.4 – 0.5 | value within the normal range ← your result |
| 0.5 – 0.6 | elevated metabolic risk ← your result |
| 0.6 and above | high metabolic risk ← your result |
The WHtR indicator, in other words waist to height is the simplest of the useful indicators you can calculate at home. You divide waist circumference by height, both in the same units. Someone 175 cm tall with an 85 cm waist has a WHtR of 0.49. The rule can be remembered in a single phrase: waist circumference should be less than half of your height. That's enough — there are no separate thresholds for women and men, and no adjustment for age.
The advantage of WHtR over BMI is that it looks at waist circumference, and so indirectly at the visceral fat that gathers around the organs of the abdominal cavity. It is precisely this type of fat that is hormonally active and is linked to elevated risk of metabolic disorders. BMI doesn't see this — two people with an identical BMI of 26 can have a WHtR of 0.45 and 0.58, meaning a completely different risk profile. WHtR also doesn't suffer from the flaw that affects WHR: when both waist and hips increase, the waist/hip ratio may stay unchanged, while waist/height rises immediately, because height is constant.
The scale is short. A value below 0.4 means a waist circumference below the typical range, values from 0.4 to 0.5 fall within the norm, 0.5–0.6 signals elevated metabolic risk, and above 0.6 the risk is described as high. Don't forget, though, that the number only tells you about one thing: waist circumference in relation to height. It knows nothing about body composition or state of health. The indicator isn't used in pregnant women nor in children under 6 years of age. When the value comes out above 0.6 consult it with a doctor.
Frequently asked questions
What WHtR value is normal?
A normal value falls within the range of 0.40 to 0.50. A result from 0.50 to 0.60 indicates elevated metabolic risk, and above 0.60 the risk is high. The thresholds are the same for women and men.
What is the „waist below half your height” rule?
This is the practical translation of the WHtR threshold of 0.50. A person 180 cm tall should have a waist circumference below 90 cm, and someone 165 cm tall below 82.5 cm. Exceeding this value means a WHtR above 0.50.
Is WHtR better than BMI?
For assessing metabolic risk, usually yes, because it measures waist circumference, and so indirectly visceral fat. Two people with the same BMI of 26 can have a WHtR of 0.45 and 0.58. BMI, on the other hand, better describes overall body mass in relation to height.
Where exactly do you measure the waist?
At the narrowest point of the torso, roughly halfway between the lower rib and the top edge of the hip bone. Measure while standing straight, on a relaxed exhale, without pulling in your stomach. A two-centimetre difference changes WHtR by about 0.01.
