Calculate Your Waist-to-Hip Ratio (WHR)
Enter your waist and hip measurements using the same unit (cm or inches). This tool gives a quick screening estimate of body fat distribution.
Your waist-to-hip ratio is one of the simplest ways to understand where your body stores fat. While total body weight matters, fat carried around the abdomen is linked to a higher risk of metabolic and cardiovascular issues. WHR gives you a fast, practical screening number you can track over time.
What is waist-to-hip ratio?
Waist-to-hip ratio (WHR) compares the size of your waist to the size of your hips:
WHR = Waist Circumference ÷ Hip Circumference
A higher ratio generally means more fat is stored around the midsection relative to the hips. Lower ratios usually indicate more fat distribution around the hips and thighs.
How to measure correctly
1) Measure your waist
- Stand upright, relaxed, and breathe out normally.
- Wrap a flexible tape measure around the narrowest part of your torso (usually above the navel and below the ribcage).
- Keep the tape snug but not tight against the skin.
2) Measure your hips
- Measure at the widest part of your buttocks/hips.
- Keep the tape level all the way around.
- Use the same unit for both measurements.
How to interpret your WHR
WHR is a screening tool, not a diagnosis. Different organizations use slightly different cutoffs. A practical reference is shown below:
| Sex | Low Risk | Moderate Risk | High Risk |
|---|---|---|---|
| Female | < 0.80 | 0.80 to 0.84 | ≥ 0.85 |
| Male | < 0.90 | 0.90 to 0.99 | ≥ 1.00 |
| Other / Unspecified | < 0.85 | 0.85 to 0.94 | ≥ 0.95 |
Why WHR can be useful
- Fast and inexpensive: You only need a tape measure.
- Focuses on fat distribution: Central fat can be more strongly associated with health risk than weight alone.
- Great for progress tracking: Changes in waist size can appear even when body weight changes slowly.
What to do if your ratio is elevated
Nutrition basics
- Center meals around lean protein, vegetables, fruit, legumes, and high-fiber carbs.
- Reduce liquid calories and ultra-processed snacks.
- Aim for consistent portion control rather than crash dieting.
Movement and training
- Accumulate 150+ minutes/week of moderate activity (walking, cycling, swimming).
- Add resistance training 2–4 days per week to preserve muscle.
- Increase daily movement: steps, stairs, short movement breaks.
Lifestyle factors
- Sleep 7–9 hours most nights.
- Manage stress with routines you can repeat (walks, breathing drills, journaling).
- Track waist and WHR monthly under the same conditions.
Limitations of this calculator
This calculator gives a useful estimate, but it does not replace medical advice. WHR does not account for age, ethnicity, muscle mass, pregnancy, or specific health conditions. For personalized recommendations, speak with a qualified healthcare professional.
Frequently asked questions
Can I use inches instead of centimeters?
Yes. WHR is a ratio, so the unit cancels out. Just use the same unit for both measurements.
Is WHR better than BMI?
They answer different questions. BMI estimates overall body size relative to height, while WHR highlights fat distribution. Many clinicians use both together.
How often should I recheck WHR?
Every 2 to 4 weeks is enough for most people. Daily changes are usually just normal fluctuations.
Bottom line: WHR is a quick, practical health signal. Use it to guide habits over time—not to judge yourself from a single number.
