Waist-to-Height & Waist-to-Hip Calculator
Calculate both waist ratios in one tool using stable source-value unit switching.
Waist-to-Hip and Waist-to-Height Ratio Calculator helps you measure two widely used body ratios in one place using your waist, height, hip circumference, and sex for interpretation. It is useful for people who want a fast screening tool for body fat distribution and general health-risk patterns without doing the math manually. This calculator shows your waist-to-height ratio, waist-to-height category, waist-to-hip ratio, waist-to-hip category, and a half-height waist target. Because it combines both WHtR and WHR in one tool, it is practical for quick check-ins, progress tracking, and comparing simple body measurements over time. The live page also makes clear that it is for general education only and not a medical diagnosis tool.

Important Note About Ratio Results
This calculator is best used as a quick educational screening tool, not as a medical diagnosis. Waist-to-height ratio and waist-to-hip ratio can help you understand central fat distribution and simple risk patterns, but they do not replace professional medical advice, clinical testing, or a full health assessment. Use the results as a practical reference, especially if you are tracking changes over time, and speak with a qualified healthcare professional if you need individual medical guidance. The live page already states that the calculator is for general education only and does not replace medical advice.

You can use either centimeters or inches, depending on how you measured. - Enter your waist circumference.
This value is used in both the WHtR and WHR formulas. - Enter your hip circumference.
This value is used to calculate your waist-to-hip ratio. - Click Calculate.
The calculator uses the formulas WHtR = waist ÷ height and WHR = waist ÷ hip. - Review your results.
The page shows your waist-to-height ratio, waist-to-height category, waist-to-hip ratio, waist-to-hip category, and half-height waist target. - Reset if needed.

Waist-to-Height Ratio vs Waist-to-Hip Ratio
Waist-to-height ratio (WHtR) compares your waist measurement with your height. It is often used as a simple way to screen for central fat distribution, and this page also highlights the common reference point that your waist should stay under half your height.
Waist-to-hip ratio (WHR) compares your waist measurement with your hip measurement. On this calculator, the ratio itself is straightforward math, but the category interpretation depends on the selected sex, which is why that input is included.
The main benefit of this page is that it calculates both ratios at once from one set of measurements, so users do not need to switch between separate tools to compare WHtR and WHR. That makes this page stronger for combined body-risk and body-shape intent, while your separate Waist-to-Hip Ratio Calculator is better for WHR-only intent.
Frequently Asked Questions
What does the Waist-to-Hip & Waist-to-Height Ratio Calculator do?
This calculator measures two common body ratios in one tool: waist-to-height ratio (WHtR) and waist-to-hip ratio (WHR). It uses your entered height, waist, and hip measurements to calculate both values and show related categories.
What measurements do I need to enter?
You need to enter your height, waist circumference, and hip circumference. You can input these values in either centimeters or inches.
Why do I need to select sex in this calculator?
The page states that sex is used for waist-to-hip interpretation only. That means it affects the category shown for your waist-to-hip ratio, but not the basic ratio formula itself.
How is waist-to-height ratio calculated?
The calculator uses the formula WHtR = waist ÷ height. After you enter your measurements and click Calculate, it displays both the numerical ratio and the related category.
How is waist-to-hip ratio calculated?
The calculator uses the formula WHR = waist ÷ hip. It then shows your ratio and a waist-to-hip category based on the selected sex.
What results does the calculator show?
The results section shows five outputs: waist-to-height ratio, waist-to-height category, waist-to-hip ratio, waist-to-hip category, and half-height waist target.
What is the half-height waist target?
The calculator includes a half-height waist target, based on the common guideline that your waist should be under half your height. This is shown directly in the results section as a quick reference target.
Can I use inches instead of centimeters?
Yes. The height, waist circumference, and hip circumference fields support both cm and in.
Do I need to calculate both ratios separately?
No. This tool is designed to calculate both waist ratios in one tool, so you can get WHtR and WHR results together from the same inputs.
Is this calculator a medical diagnosis tool?
No. The page clearly states that the calculator is for general education only and does not replace medical advice.
