Navy Method vs. Other Measurement Methods
DEXA scan is the gold standard with approximately 1% error, but requires a medical facility. Hydrostatic weighing (water displacement) is very accurate but involves being submerged in water. Skinfold calipers offer moderate accuracy with a trained measurer. The Navy method (tape measure) gives a good estimate with 3-4% accuracy and is free to do at home. BMI-based estimates are the least accurate as they ignore body composition entirely.
