About

BodyFatCalculator.us was created to give people a fast, free, and accurate way to estimate their body fat percentage using nothing more than a tape measure — no gym membership, no expensive scan, no signup required.

We built this tool around the U.S. Navy Circumference Method because it strikes the best balance between accessibility and accuracy for everyday use, backed by decades of use in military fitness standards.
