Frequently Asked Questions
What is the Navy method for body fat calculation?
The Navy method uses body measurements (height, neck, waist, and hip for females) to estimate body fat percentage. It's a simple, non-invasive method that provides reasonable estimates for most people.
How accurate is this calculator?
The Navy method provides a good estimate but may not be as accurate as DEXA scans or hydrostatic weighing. It's best used as a general guideline and for tracking changes over time.
How do I take accurate measurements?
Measure in the morning before eating, using a flexible tape measure. For waist, measure at the narrowest point. For neck, measure just below the Adam's apple. For hip (females), measure at the widest point.
What are healthy body fat percentages?
For men: 6-24% is generally healthy. For women: 10-31% is generally healthy. Athletes typically have lower percentages, while essential fat is the minimum needed for normal body function.
Can I use this if I'm pregnant or have certain medical conditions?
This calculator may not be accurate for pregnant women, people with certain medical conditions, or those with significant muscle mass. Consult a healthcare provider for personalized assessment.
