About this Tool & FAQ
How accurate is the US Navy Body Fat Calculator?
This mathematical formula provides a reasonable estimate (within 3-4% accuracy for most people). For precise medical measurements, consider a DEXA scan or hydrostatic weighing.
How do I measure myself properly?
Use a flexible tape measure. For the neck, measure just below the larynx (Adam's apple). For the waist, measure directly at the navel (men) or at the narrowest point (women). For the hips (women only), measure at the widest circumference.
What is a healthy body fat percentage?
For men, a generally healthy range is 14-24%. For women, it is 21-31%. Athletes and highly fit individuals often have lower percentages.
