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 |
Theory — what is the WHtR waist-to-height ratio?
WHtR divides waist circumference by height, using the same unit for both measurements. The calculator applies this ratio and returns a single number, so someone who is 175 cm tall with an 85 cm waist gets a WHtR of 0.49. A result between 0.40 and 0.50 is considered normal, while a value from 0.50 to 0.60 signals increased risk. The measure follows the simple rule that waist should stay below half of height, which many consider easier to interpret than BMI.
