Quick Help: Common Questions
Before reaching out, these quick links may already have the answer you're looking for. Our guides section covers the most frequently asked topics in depth.
See our step-by-step measurement guide for detailed instructions on measuring your waist and hips accurately. Proper technique matters -- using the right landmark on your body and keeping the tape level can shift your result by several centimeters. The guide includes illustrations, common mistakes, and a printable checklist you can take with you.
Our waist-to-hip ratio chart breaks down every risk category for both men and women, based on thresholds established by the World Health Organization. You'll see where your number falls and what each range typically indicates about body-fat distribution and cardiovascular risk.
If your WHR places you in a moderate or high-risk category, our health risks guide explains what the research says. Studies such as the INTERHEART study have linked elevated WHR to increased risk of heart disease, type 2 diabetes, and other conditions. For personalized advice, always consult a qualified healthcare provider.

Before You Contact Us
Here are answers to some common questions we receive. Following these three steps often resolves your question faster than waiting for an email reply:
Is this calculator accurate?
Our calculator uses standard formulas established by medical and fitness research. The waist-to-hip ratio formula (WHR = waist ÷ hips) and risk thresholds are based on World Health Organization guidelines. The BMI formula follows the standard weight(kg) ÷ height²(m²) calculation. However, these are screening tools, not medical diagnoses. For personalized health advice, please consult a healthcare provider. You can learn more on our About page, or read our formula explained guide for details on the math behind each calculation.
Can I use this on my website?
Linking: You're welcome to link to our calculator from your website, blog, or social media. No permission needed for standard hyperlinks.
Embedding: If you'd like to embed the calculator directly on your site (via iframe or other methods), please contact us first to discuss. We'll need to understand your use case and may have specific requirements.
How do I measure correctly?
Accurate measurements are essential for reliable results. See our detailed step-by-step measurement guide with professional protocols, common mistakes to avoid, and a quick-reference checklist. If you're unsure what your results mean, our WHR chart and health risks guide explain each risk category in detail.
