What is a Waist-Hip Ratio?

A Waist-to-Hip Ratio Calculator divides your waist circumference by your hip circumference to produce a single number that the World Health Organization uses as a simple indicator of health risk linked to how body fat is distributed. Unlike BMI, which only considers overall weight relative to height, WHR specifically captures whether fat is concentrated around the abdomen (associated with higher risk) or around the hips (associated with lower risk).

This calculator applies WHO's gender-specific risk thresholds automatically, so you get not just a number but a clear risk category. It works well alongside the BMI Calculator and Body Fat Calculator for a more complete view of body composition.

Why Use a Waist-to-Hip Ratio Calculator?

Two people with the same BMI can have very different health risk profiles depending on where their body fat is concentrated, abdominal fat is more strongly linked to cardiovascular and metabolic risk than fat stored around the hips and thighs. WHR captures this difference in a way that weight and BMI alone cannot, making it a useful complementary metric rather than a replacement for other measures.

This calculator makes that calculation immediate, converting two simple tape-measure readings into a clear risk category based on WHO's published thresholds. Anyone tracking their health over time can monitor changes in fat distribution even when their overall weight stays relatively stable, the same way the Ideal Weight Calculator tracks a different but related aspect of body composition.

Who Should Use This Calculator?

  • Anyone tracking overall health risk who wants a measure that captures fat distribution, not just total body weight.
  • People monitoring fitness or weight loss progress who want to see changes in body shape that BMI alone might not reflect.
  • Healthcare-conscious individuals wanting a quick, WHO-aligned screening check between regular medical checkups.
  • Fitness coaches and trainers tracking client progress across multiple body composition metrics.
  • Anyone curious about their body shape classification, apple versus pear, and what it means for general health risk.

What Insights Does the Waist-to-Hip Ratio Calculator Give You?

The calculator returns one core figure with an immediate practical interpretation:

  • Waist-to-Hip Ratio, the raw ratio of waist to hip circumference, the number used directly in WHO's risk classification.
  • Risk Category, Low, Moderate, or High Risk, based on WHO's published gender-specific thresholds, giving immediate context to what your ratio means.

Because the thresholds differ between men and women, the calculator automatically applies the correct ones based on the gender you select, so you don't need to look up which set of cutoffs applies to you.

How to use this Waist-Hip Ratio calculator

  1. Select your Gender, Male or Female, since WHO uses different risk thresholds for each.
  2. Measure your waist at its narrowest point and enter it as Waist Circumference.
  3. Measure your hips at their widest point and enter it as Hip Circumference.
  4. Read your Waist-to-Hip Ratio result.
  5. Check the Risk Category card to see where your ratio falls relative to WHO's published thresholds.

Formula & Methodology

The calculation itself is a simple division:

WHR = Waist Circumference ÷ Hip Circumference

WHO risk categories applied:

- Men: Low risk < 0.90, Moderate risk 0.90–0.99, High risk ≥ 1.0
- Women: Low risk < 0.80, Moderate risk 0.80–0.84, High risk ≥ 0.85

Worked example: for a man with an 85 cm waist and 100 cm hips:
- WHR = 85 ÷ 100 = 0.85
- Since 0.85 is below the 0.90 threshold for men, this falls in the Low Risk category.

Frequently Asked Questions

What is waist-to-hip ratio?
Waist-to-hip ratio (WHR) is calculated by dividing your waist circumference by your hip circumference, giving a number that indicates how body fat is distributed between your midsection and hips. The World Health Organization uses WHR as a simple indicator of health risk associated with abdominal fat.
What is a healthy waist-to-hip ratio?
For men, a WHR below 0.90 is considered low risk; for women, a WHR below 0.80 is considered low risk, according to WHO guidelines. Ratios above these thresholds indicate progressively higher health risk associated with central (abdominal) fat distribution.
Why does WHO use different thresholds for men and women?
Men and women naturally carry fat differently, men tend to store more fat around the abdomen, while women tend to store more around the hips and thighs, so the same ratio doesn't carry the same health implications for both. WHO's gender-specific thresholds account for this natural difference in body composition.
What does a high waist-to-hip ratio indicate?
A high WHR indicates more fat is stored around the abdomen relative to the hips, sometimes described as an 'apple' body shape, which is associated with higher risk of cardiovascular disease, type 2 diabetes, and other metabolic conditions compared to a 'pear' shape with fat concentrated around the hips.
How do I measure my waist and hip circumference correctly?
Measure your waist at its narrowest point, typically just above the belly button, while standing relaxed (not after inhaling or flexing). Measure your hips at their widest point, around the buttocks. Use a flexible tape measure and keep it level and snug but not tight.
What is the difference between WHR and BMI?
BMI measures overall body weight relative to height without distinguishing where fat is stored, while WHR specifically measures fat distribution between the waist and hips. Some research suggests WHR may be a better predictor of cardiovascular risk than BMI alone, since fat location matters as much as total fat amount. Many people check both, see the [BMI Calculator](/bmi-calculator/) for the overall measure.
Can WHR be used alongside other health calculators?
Yes, WHR works well alongside the [Body Fat Calculator](/body-fat-calculator/) and [Ideal Weight Calculator](/ideal-weight-calculator/) for a fuller picture of body composition and health risk, since each measures a different aspect of body shape and fat distribution.
Is waist-to-hip ratio accurate for everyone?
WHR is a useful general screening indicator but has limitations, it doesn't account for muscle mass, bone structure, or individual variation, and may be less reliable for very tall, very short, or highly muscular individuals. It's best used as one data point alongside other health measures rather than a definitive diagnosis.
What body shape has the lowest health risk?
A 'pear' body shape, with fat concentrated around the hips and thighs rather than the abdomen, is generally associated with lower cardiovascular and metabolic risk than an 'apple' shape with central abdominal fat, even at similar overall body weight.
Should I track WHR over time?
Yes, tracking WHR periodically (monthly or quarterly) can show meaningful trends in body composition, especially alongside lifestyle changes like diet or exercise, even when overall weight or BMI doesn't change much. A decreasing WHR generally indicates a healthier shift in fat distribution.
