Waist-to-hip ratio divides your waist circumference by your hip circumference to measure fat distribution. By WHO criteria, 0.90 or below is low risk for men and 0.80 or below for women; 1.0+ (men) or 0.85+ (women) indicates abdominal obesity — the fat pattern most linked to diabetes and heart disease.
Where your body stores fat predicts health risk better than how much you weigh — and the waist-to-hip ratio is the classic way to measure it. Two tape measurements, one division, and you know whether your fat pattern is the lower-risk “pear” or the higher-risk “apple” that concentrates fat around the organs. This waist-to-hip ratio calculator does the math and interprets your result against WHO cutoffs.
Measure, calculate, then read on: exactly how to take the two measurements, the full ratio chart, and what an elevated ratio means in practice.
Waist-to-Hip Ratio
Health risk indicator from abdominal fat distribution.
How to measure waist and hips correctly
The ratio is only as good as the tape work. WHO protocol:
- Waist: stand relaxed, find the midpoint between your lowest rib and the top of your hip bone (roughly at or just above the navel), wrap the tape horizontally, snug but not compressing, and measure at the end of a normal exhale.
- Hips: tape around the widest part of your buttocks, feet together, tape level all the way round.
Measure directly on skin or thin clothing, twice, and take the average. Then: WHR = waist ÷ hip. A 80 cm waist over 100 cm hips is a ratio of 0.80.
Waist-to-hip ratio chart
The WHO risk categories:
| Risk level | Men | Women |
|---|---|---|
| Low risk | 0.90 or below | 0.80 or below |
| Moderate risk | 0.91–0.99 | 0.81–0.84 |
| Substantially increased risk (abdominal obesity) | 1.0 and above | 0.85 and above |
The sex difference is real biology: estrogen steers fat toward hips and thighs, so healthy cutoffs sit lower for women.
Apple vs pear: why the ratio predicts risk
A high WHR means proportionally more fat around the abdomen — and abdominal fat is disproportionately visceral fat, the metabolically active kind wrapped around the organs. Visceral fat drives insulin resistance and inflammation, which is why an elevated WHR associates with type 2 diabetes, high blood pressure and cardiovascular disease even at a “normal” body weight. Hip-and-thigh fat, by contrast, is mostly subcutaneous and metabolically quieter — the pear shape genuinely carries less risk than the apple at the same weight.
WHR vs BMI vs waist-to-height ratio
Each tool sees something the others miss. BMI measures overall heaviness but not distribution. WHR measures distribution but can look falsely reassuring when waist and hips grow together. The waist-to-height ratio — keep your waist under half your height — is the simplest and, in recent research, often the strongest single screen. Best practice is simple: check a waist-based measure alongside BMI, and let our body fat calculator fill in the composition picture.
How to improve your ratio
You cannot spot-reduce a waist, but abdominal — especially visceral — fat responds fastest to overall fat loss: a moderate calorie deficit (our calorie deficit calculator sizes one), regular aerobic exercise plus resistance training, better sleep and less alcohol. Visceral fat is typically the first fat to shrink when these changes hold — ratios often improve within months.
This tool is informational. A ratio is a screening measure, not a diagnosis — interpret persistent high results with a physician, especially alongside other risk factors.
Frequently asked questions
What is a good waist-to-hip ratio?
0.90 or below for men and 0.80 or below for women. Ratios of 1.0+ (men) or 0.85+ (women) indicate abdominal obesity by WHO criteria.
Where exactly do I measure my waist?
At the midpoint between your lowest rib and the top of the hip bone — usually at or slightly above the navel — with the tape horizontal and snug, at the end of a normal breath out.
Why does waist-to-hip ratio matter more than weight?
Because it captures fat distribution: abdominal fat is largely visceral fat, the type most linked to diabetes and heart disease. Two people at identical weights can carry very different risk depending on where the fat sits.
Can WHR be misleading?
Occasionally — if waist and hips increase together the ratio stays flat while risk rises, and very muscular hips can flatter it. That is why pairing it with waist-to-height ratio or waist circumference alone is smart.
How fast can the ratio improve?
Visceral fat responds quickly to a sustained calorie deficit and exercise — measurable waist reduction within 8–12 weeks is realistic for most people.
