How this is calculated
The U.S. Navy method estimates body fat from circumference measurements rather than skinfold calipers or scans, which makes it a practical option to do at home with just a tape measure. It's reasonably accurate for most body types, though it can be less precise for people with very high muscle mass or unusual body proportions.
