Hoe het werkt

  • Measure the waist at the navel for men and at the narrowest point for women.
  • Measure the neck just below the larynx.
  • The method is usually within about 3–4 percentage points of lab measurements.
  • It is an estimate for general reference, not a medical assessment.

Worked example: man, 178 cm, neck 38 cm, waist 85 cm

  1. 1Waist − neck = 47 cm.

Veelgestelde vragen

How accurate is the US Navy method?

It is a reasonable estimate for most people, typically within a few percentage points of more expensive methods.

Is body fat better than BMI?

It tells you more about body composition, since BMI cannot distinguish muscle from fat.

Why do women need a hip measurement?

Women store more fat around the hips, so the formula includes it for a better estimate.
