Understanding the measure
What Is Body Fat Percentage?
Body fat percentage estimates how much of total body weight is fat tissue. The rest includes muscle, bone, water, organs, and other lean tissue. It offers different information from body weight alone, but any estimate should be interpreted with care.

How Does the Body Fat Calculator Work?
This calculator uses the U.S. Navy circumference method. It combines height with neck and waist measurements for men, and height with neck, waist, and hip measurements for women. The measurements are converted to inches before the formula is applied.
Consistent measurements matter
Use the same tape placement and gentle tension each time. Small differences in circumference can change the estimate.
Two different estimates
Body Fat Percentage vs BMI
BMI compares body weight with height, while body fat percentage estimates the proportion of body weight made up of fat. Neither measure provides a complete picture of health, and both have limitations.

Why Body Fat Estimates Can Vary
Tape Placement
Measuring at a slightly different point can change the circumference and final estimate.
Measurement Tension
Pulling the tape too tightly or leaving it too loose may affect the result.
Estimation Method
Different formulas and devices use different assumptions, so their results may not match exactly.
Common questions
Frequently Asked Questions
What is a healthy body fat percentage?
Reference ranges vary by sex, age, and source. The categories shown above are broad general references, not targets or diagnoses for every individual.
Is this calculator accurate?
It provides an estimate based on circumference measurements. Measurement technique and individual body shape can affect how closely the result reflects actual body composition.
Is BMI the same as body fat percentage?
No. BMI relates weight to height. Body fat percentage estimates the proportion of body weight that is fat tissue.
Why can measurements affect the result?
The formula uses differences between circumferences, so even a small change in tape placement or tension can shift the estimate.
