How We Estimate Body Fat (and Its Limits)
The photo and ranges on this page show a typical presentation of 21% body fat. Real appearance varies with frame size, muscle mass, where you store fat, age, and lighting, so two people at 21% can look different. The percentage itself is an estimate: home methods like the U.S. Navy circumference formula are typically accurate to within 3 to 4 points, while DEXA and hydrostatic weighing are more precise but require a clinic.
These guides are educational, not a medical diagnosis or a substitute for assessment by a qualified professional. Our figures and methodology are reviewed by Andrew Menechian, Head of Fitness; see the full body composition methodology for formulas and sources.
