Waist-to-hip ratio calculator

Divide your waist by your hips to see your waist-to-hip ratio and where it falls on the World Health Organization health-risk scale for your sex. A quick read on how your fat is distributed.

Risk bands follow the World Health Organization cut-offs, which differ by sex (men: low under 0.90, high at 1.0 and above; women: low under 0.80, high above 0.85). It is a screening guide, not a diagnosis.

How it works

How waist-to-hip ratio is scored

Your waist-to-hip ratio is simply your waist measurement divided by your hip measurement. It captures fat distribution, whether you carry weight around the middle (an apple shape) or the hips and thighs (a pear shape). Abdominal fat carries more health risk, so a higher ratio matters more than the same weight lower down.

The World Health Organization sets the risk bands, and they differ by sex. For men, below 0.90 is low risk and 1.0 or above is high. For women, below 0.80 is low and above 0.85 is high. It is a screening guide, useful alongside your body-fat percentage, not a medical diagnosis.

Questions

Waist-to-hip ratio questions

What is a good waist-to-hip ratio?
By the WHO cut-offs, low risk is below 0.90 for men and below 0.80 for women. The higher the ratio, the more weight is carried around the middle, which is linked to greater health risk.
How do I measure for waist-to-hip ratio?
Measure your waist at the navel and your hips at the widest point, both with the tape level and snug. Use the same unit for both, since the ratio is a division and units cancel out.
What does a high waist-to-hip ratio mean?
A ratio of 1.0 or higher for men, or above 0.85 for women, falls in the high-risk band. It signals more abdominal fat, which carries more cardiovascular and metabolic risk than fat on the hips and thighs.
Is waist-to-hip ratio better than BMI?
For body-shape and abdominal-fat risk, WHR often tells you more than BMI because it looks at where fat sits, not just total weight. Many people use both together.
