Profile used

female

Uses standard waist-to-hip ratio formula. Reviewed for arithmetic accuracy. Screening measure only. Does not replace medical or professional health advice.

Personalized interpretation

Your waist-to-hip ratio is 0.80.

This may fall within the moderate reference range reference range for the selected profile.

Waist-to-hip ratio can provide context about body fat distribution, but it does not measure overall health by itself.

Measurement technique, body composition, age, ethnicity, and medical history can affect interpretation.

If you have concerns about waist size or health risk, consider speaking with a qualified healthcare professional.

What waist-to-hip ratio means

WHR compares waist circumference with hip circumference.
It gives a rough indicator of fat distribution.
Higher ratios can reflect more abdominal fat distribution.
It is a screening measure, not a diagnosis.

How to measure waist and hips

Use a flexible tape measure.
Measure consistently at the same landmark.
Measure hips at the widest point.
Keep tape snug but not compressing skin.
Repeat measurements for accuracy.

Waist-to-hip ratio is not a diagnosis, treatment plan, or replacement for professional medical advice.

Trends over time may provide more context than one isolated measurement.

Formula explanation

Waist-to-Hip Ratio = Waist Circumference ÷ Hip Circumference

Waist and hip must use the same unit. The ratio itself has no unit.

Example 1

Waist: 80 cm

Hips: 100 cm

WHR = 80 ÷ 100 = 0.80

Example 2

Waist: 34 in

Hips: 40 in

WHR = 34 ÷ 40 = 0.85
