FAQ
How accurate is this method?
The US Navy method is a simple circumference-based estimate and can differ from results using a body composition scale or hydrostatic weighing. Treat it as a rough guide.
Where exactly should I measure?
Measure the neck just below the larynx, the waist at the level of the navel, and the hips at their widest point, keeping the tape horizontal.
Does a high or low body fat percentage directly indicate health?
Body fat percentage is just one indicator of body composition. If you have concerns, consult a healthcare professional or use a dedicated measurement device.
