How to use this calculator
Compare waist and hip measurements. Enter waist circumference (cm), hip circumference (cm). The result updates when you change an input. To compare two sets of inputs, save scenario A, then enter the second set; the result panel shows the difference.
Formula and limits
Waist-to-hip ratio = waist circumference ÷ hip circumference. Use the same units and consistent measurement technique. This is not a diagnosis.
Worked example
The following example uses the calculator’s starting values. It is an illustration of the method, not a recommended target.
| Input | Example value |
|---|---|
| Waist circumference (cm) | 85 |
| Hip circumference (cm) | 100 |
Waist-to-hip ratio: 0.85
Interpreting your result
These tools describe measurements; they do not diagnose conditions or prescribe a target. Measurement technique, age, pregnancy, body composition, and other context can affect interpretation. Discuss clinical questions with a qualified professional.
Comparing alternatives
Save the first result as scenario A, then change one input. The comparison shows the numeric difference; it does not label either result as better. Choose inputs that describe realistic alternatives. Values shown on screen are rounded, so calculations from rounded intermediate results may differ slightly.
