Questions, answered
What does a body fat calculator estimate?
The share of your body weight that is fat, called your body fat percentage. Everything else, muscle, bone, organs and water, is lean mass. Together the two are your body composition.
How do I determine my body fat percentage at home?
With a soft tape measure. Measure your neck just below the voice box, your waist at the navel, and for women the hips at their widest, standing relaxed and breathing out. Enter those with your height and the US Navy equations give the estimate.
Which method is more accurate, the tape or BMI?
The tape. It reads your own shape, and the US Navy equations usually land within a few points of a laboratory scan. The BMI method only knows your height, weight, age and sex, so it cannot tell muscle from fat.
4 more questions
What is a healthy body fat level?
Your result shows the American Council on Exercise bands, from essential fat to above average. Women's bands sit higher than men's because women carry more essential fat. Where fat sits matters too: fat around the waist and organs says more about metabolic health than the total.
How is body fat different from BMI?
BMI, the body mass index, is weight divided by height squared; it measures size, not fat. South Asian adults often carry more body fat at the same BMI than Europeans (WHO Expert Consultation, Lancet 2004), which is why a body fat estimate and a waist measurement add to it.
How is body composition measured more precisely?
A DEXA scan is the clinical reference. Bioimpedance scales and callipers in a trained hand are common alternatives. Every method has an error, so the most useful figure is the same method, repeated under the same conditions, over months.
Is anything I type stored?
No. Your measurements stay on your device: the arithmetic runs in your browser and is never sent.
