Frequently Asked Questions
How accurate is the Navy Method?
The U.S. Navy Method provides a reasonably accurate estimate (about 3-4% margin of error) when measurements are taken properly. It's most effective for tracking relative changes over time rather than absolute values.
Why do women need hip measurements?
The formula accounts for typical female fat distribution patterns. Hip measurements help improve accuracy for women as they tend to store more fat in lower body areas.
How often should I measure my body fat?
For consistent tracking, measure every 2-4 weeks. Daily measurements aren't recommended as body fat changes slowly and daily fluctuations can be misleading.
What's the best time to take measurements?
Measure in the morning before eating or drinking, after using the restroom. Wear minimal clothing and ensure the tape measure is snug but not compressing the skin.
Can I use this if I'm pregnant?
This calculator isn't suitable for pregnant women as pregnancy significantly alters body composition and fat distribution patterns.
How does this compare to other methods?
While not as precise as DEXA scans or hydrostatic weighing, it's more accessible and provides better accuracy than BMI for assessing body composition.
