How it works
What this calculadora actually does
Waist-to-Hip Ratio calculadora is built to give you a clean, explainable answer without the usual wall of ads — type the numbers, read the result, keep moving.
If a value drops into a red band, act; if it is borderline, track. Measure at the same time of day for consistency — then work out the number and the rest of this page explains what the answer means.
Divide waist circumference by hip circumference at their widest points. WHO health cut-offs: men >0.90 and women >0.85 indicate increased cardiometabolic risk.
The formula we run is WHR = waist / hip. You'll see each term laid out in the worked example below.
Following the method end to end
Here's what happens when you plug real numbers in.
Divide waist circumference by hip circumference at their widest points. WHO health cut-offs: men >0.90 and women >0.85 indicate increased cardiometabolic risk.
Every run comes back to WHR = waist / hip — change the inputs, the structure of the answer stays.
When to use this calculadora
Waist-to-Hip Ratio calculadora is aimed at people arriving with questions like these:
- "Waist hip ratio formula"
- "Whr healthy range"
- "Visceral fat risk"
- "Measure waist correctly"
- "What is waist to hip ratio"
- "How to calculate waist to hip ratio"
When to reach for something else
Every tool has an edge where it stops being the right answer. Waist-to-Hip Ratio calculadora is no exception:
- For legally binding tax or medical decisions — cross-check with HMRC, NHS or a qualified professional.
- For very large or very small extremes the rounding error outgrows the useful precision.
- When the underlying rate or threshold has changed since the page was last reviewed — always verify with the primary source.
- When the input you have is already a derived figure (net of something) — feeding it in as "gross" will double-subtract.
Mistakes we see over and over
Every time you work out the number for a new scenario, one of these creeps in — it's worth knowing them ahead of time.
- Entering a monthly figure into an annual field (or vice versa).
- Forgetting a leading zero on decimals (.5 instead of 0.5 breaks some inputs).
- Trusting a single reading when the underlying number naturally fluctuates.
- Comparing two answers that used different assumptions — always re-run both.
- Skipping the formula box. If you don’t understand the method, the answer is just a vibe.
The sources behind the numbers
Where the maths needs an external authority, we cross-check against:
- WHO
- NHS
Works well alongside
If this question keeps coming up for you, the same cluster of tools usually comes next:
- BMI calculadora — Check your Body Mass Index in metric or imperial, with NHS weight categories explained.
- Body Fat Percentage calculadora — Estimate body fat using the US Navy tape method (waist, neck and — for women — hip circumference) with NHS-aligned healthy ranges.
