## Quick Answer

Calculate your waist-to-hip ratio (WHR) from waist and hip circumferences measured at the landmarks WHO specifies.

## Definition

The waist-to-hip ratio is a dimensionless ratio calculated by dividing the waist circumference by the hip circumference. A waist-to-hip ratio calculator determines this ratio to assess body fat distribution and evaluate associated health risks, particularly cardiovascular disease and type 2 diabetes. The World Health Organization defines abdominal obesity as a ratio above 0.90 for men and above 0.85 for women. WHO specifies the waist be measured at the midpoint between the lowest rib and the top of the iliac crest, not at the navel, and reports that measuring at the navel underestimates the true waist circumference. Epidemiologists and medical professionals use this metric alongside body mass index to gauge visceral fat accumulation and general health status.

## How to Use

1. **Select measurement unit** — Choose between inches and centimeters for your circumference measurements.
2. **Enter waist and hip sizes** — Measure the waist at the midpoint between the lower margin of the last palpable rib and the top of the iliac crest, and the hip at the largest circumference of the buttocks, keeping the tape parallel to the floor for both. Type both circumferences into the input fields.
3. **Read ratio and risk level** — Review the ratio against the bands this page draws, and against the single cut-off WHO publishes for substantially increased risk.
