Waist-to-Hip Ratio (WHR) Calculator – Measure Fat Distribution and Health Risk
The Waist-to-Hip Ratio (WHR) Calculator measures the balance between your waist and hip circumference — a proven indicator of body fat distribution and cardiometabolic risk. Unlike BMI, which only considers weight and height, WHR helps you understand where fat is stored, giving deeper insight into your body composition and long-term health profile.
This calculator features a live silhouette preview that morphs dynamically with your measurements, plussex-specific risk bands and an optional Waist-to-Height Ratio (WHtR) for added context. It’s simple, visual, and clinically grounded — perfect for tracking fat distribution over time or comparing progress after fitness or nutrition changes.
Combine it with our BMI, Body Fat and TDEE calculators for a full picture of health and physique.
How to Use the WHR Calculator
- Select your sex (male or female).
- Enter your waist circumference and hip circumference — in the same units (cm or inches).
- Optionally, add your height to compute your Waist-to-Height Ratio.
- Click Calculate to see your WHR, sex-specific risk band, and silhouette visualization.
- Save, email, or share your results instantly for tracking or coaching purposes.
What Is Waist-to-Hip Ratio (WHR)?
WHR is the ratio of your waist circumference divided by your hip circumference:
WHR = Waist ÷ Hip
This number reflects how body fat is distributed between the trunk (waist) and lower body (hips and thighs). Higher WHR values indicate more abdominal fat, while lower values suggest fat is distributed around the hips — often associated with lower health risk.
Why WHR Matters More Than Weight Alone
Research shows that fat distribution is more predictive of metabolic disease than overall weight or BMI. People with excess visceral fat (around the waist and organs) have higher risks of:
- Type 2 diabetes
- Cardiovascular disease
- Insulin resistance
- Hypertension and elevated triglycerides
WHR captures these differences clearly. Two people with the same BMI may have very different WHRs — and therefore very different health outlooks.
How to Measure Correctly
- Waist: Measure at the narrowest point of your torso, or just above the navel if not visible.
- Hips: Measure at the widest part of the buttocks, ensuring the tape is parallel to the floor.
- Height (optional): Measure standing straight, barefoot, without leaning or slouching.
Risk Categories for Men and Women
Healthy WHR targets vary by sex because men and women store fat differently. Use these WHO-recommended thresholds as a reference:
| Risk Level | Men (WHR) | Women (WHR) |
|---|---|---|
| Low risk | < 0.90 | < 0.80 |
| Moderate risk | 0.90–0.99 | 0.80–0.85 |
| High risk | ≥ 1.00 | ≥ 0.85 |
How to Interpret Your Results
- Low WHR: Indicates lower visceral fat and reduced chronic disease risk.
- Moderate WHR: Suggests central fat gain — improving diet and activity can lower risk.
- High WHR: Signifies abdominal obesity, increasing likelihood of insulin resistance and heart disease.
The live silhouette in this calculator adjusts to reflect your WHR visually — a unique way to connect the numbers with your actual proportions.
Understanding Body Shape Types
WHR can also describe general body shape categories:
| Shape Label | WHR Range (approx.) | Description |
|---|---|---|
| Pear | 0.65–0.80 (F) / 0.75–0.90 (M) | Wider hips than waist — typical of healthier fat distribution. |
| Balanced | 0.80–0.85 (F) / 0.90–1.00 (M) | Even proportions between waist and hips. |
| Apple | ≥ 0.85 (F) / ≥ 1.00 (M) | Wider waist than hips — linked with central adiposity. |
Waist-to-Height Ratio (WHtR)
Many researchers consider Waist-to-Height Ratio (WHtR) an even better single indicator of health risk because it accounts for body size.
WHtR = Waist ÷ Height
The general rule is simple:Your waist should be less than half your height.For example, if you’re 170 cm tall, your waist should be under 85 cm.
| WHtR Range | Health Category |
|---|---|
| < 0.40 | Underweight / possible muscle loss |
| 0.40–0.49 | Healthy range |
| 0.50–0.59 | Increased risk |
| ≥ 0.60 | High risk |
WHR vs. BMI vs. Body Fat %
These three metrics measure different aspects of your body composition:
| Measure | What It Reflects | Limitation |
|---|---|---|
| BMI | Overall body mass adjusted for height. | Does not show fat distribution or muscle mass. |
| WHR | Where fat is stored (abdominal vs. gluteal). | Needs accurate tape measurements. |
| Body Fat % | Total fat mass relative to body weight. | Requires specialized measurement for accuracy. |
For the most complete view, use all three metrics. The Body Fat Calculator estimates percentage fat using the U.S. Navy or Jackson-Pollock methods, complementing WHR and BMI data.
How to Improve Your WHR
1) Target Visceral Fat
Focus on overall fat loss through a moderate calorie deficit guided by yourTDEE and Macro calculators. Combine aerobic training (brisk walking, cycling, swimming) with resistance work.
2) Strengthen Core and Glutes
Core stability and gluteal strength enhance posture and waist shape. Try planks, hip thrusts, and rotational core work 2–3 times per week.
3) Improve Nutrition Quality
- Emphasize fiber-rich foods — calculate your ideal with the Fiber Intake Calculator.
- Prioritize lean proteins and unsaturated fats to maintain muscle while reducing fat mass.
- Reduce added sugars and refined carbs that promote central fat storage.
4) Prioritize Sleep & Stress Reduction
Cortisol from chronic stress encourages abdominal fat accumulation. Track your rest using our Sleep Quality Index andSleep Debt Calculator.
5) Track Progress Consistently
Re-measure every 4–6 weeks under similar conditions. Focus on downward WHR trends rather than single readings — small changes mean real progress.
Frequently Asked Questions
Is WHR more accurate than BMI?
Yes, for predicting health risk. BMI can’t distinguish fat distribution, but WHR reveals whether fat is stored around the abdomen (higher risk) or hips (lower risk).
Can exercise change my WHR?
Absolutely. Fat loss from regular cardio and strength training lowers waist size while preserving hips and muscle tone — improving your WHR ratio.
What’s a healthy WHR goal?
Under 0.90 for men and under 0.80 for women are ideal. Aim for steady improvements rather than drastic short-term changes.
How is WHR different from Waist Circumference alone?
Waist circumference gives absolute measurement, while WHR standardizes it relative to hips — allowing comparison across body types.
Is this calculator medically certified?
No, it’s educational. For clinical assessment, consult a physician or registered dietitian.

Conclusion
The Waist-to-Hip Ratio (WHR) Calculator gives you more than a number — it offers insight into how your body stores fat and what that means for your long-term health. While BMI or weight alone can’t distinguish between muscle and fat, WHR highlights fat distribution patterns that strongly correlate with heart and metabolic risk.
A lower WHR generally indicates healthier fat placement and lower disease risk, whereas a higher WHR signals central obesity and greater vulnerability to cardiovascular or metabolic issues. Tracking your WHR over time is one of the simplest and most powerful ways to monitor your transformation — especially when combined with Body Fat,Waist-to-Height, and TDEE analysis.
Remember, these metrics are tools — not judgments. The true goal is balance: strong core muscles, functional endurance, stable nutrition, and restful sleep. With consistent exercise, mindful eating, and recovery, your WHR will naturally improve as your body composition becomes leaner and more resilient.
