Navy Body Fat Estimation Technique

The Navy Body Fat Estimation Technique relies on a few simple body measurements to estimate one’s body fat percentage. It is an approximation, reportedly within 3% of more accurate, gold-standard techniques.

If you have recorded the required measurements described below in the Body Measurement Tracker application, your body fat percentage will automatically be estimated using the Navy technique.

Please note that the measurements differ between males and females. For best accuracy, take each measurement 3 times and record the average among the three measurements.
