Your estimated body fat is 20.1%, average for men.

  • This is the U.S. Navy circumference estimate, a quick tape-only screen that is less exact than a DEXA or hydrostatic measurement.
  • At 20.1% you are within the Navy graduated standard of 24% for your age and sex, and inside the 26% DoD maximum.
  • Losing about 6.8 kg of fat would bring you to roughly the 12.7% ideal for your age.

Next stepTake each measurement two or three times and average them, then pair this with BMI and waist-to-height ratio for a fuller picture.
