About This Body Fat Calculator

This body fat calculator estimates your body fat percentage from simple tape measurements using a widely used method. Body fat percentage can be a more useful health indicator than weight alone, because it distinguishes fat from muscle.

This is general information only and not medical advice. Tape-measurement estimates are approximate. For an accurate reading, methods like DEXA scans are used. Speak with a health professional for guidance.
