BMI = weight (kg) / height (m²). Imperial inputs are converted automatically.

A check of whether your body weight is healthy for your height.

ABSI

ABSI uses waist, BMI & height to highlight central fat distribution.

Estimates health risk based on abdominal fat distribution.

WHR

Higher values indicate more central fat; cut-offs depend on sex & age.

Shows where your body stores fat and helps assess health risk.

WHtR

WHtR = Waist / Height.

Many guidelines consider WHtR < 0.5 as lower risk (varies by source).
