Body Fat Calculator | Estimate Percentage from Measurements
Estimate body fat percentage, fat mass, and lean mass from height, weight, gender, waist, neck, and hip measurements.
Estimate Body Fat from Tape Measurements
Enter height, weight, gender, waist, neck, and hip measurements to estimate body fat percentage, fat mass, lean mass, and category range.
Measurement Accuracy Matters
Tape placement, posture, hydration, muscle mass, and formula limits can change the estimate. Track trends over time instead of treating one result as exact.
When Body Fat Estimates Help
Use it for fitness tracking, body composition notes, progress checks, and training goals. Ask a qualified professional for medical or nutrition decisions.

Frequently Asked Questions
How accurate are tape measurement estimates?
Circumference-based methods are less accurate than DEXA scanning but provide a reasonable estimate for tracking trends over time.
What is a healthy body fat percentage?
For men, 10 to 20 percent is generally considered fit. For women, 18 to 28 percent is typical. These ranges vary by age.
Why is waist measurement important?
Visceral fat stored around the abdomen is more metabolically harmful than fat elsewhere. A larger waist relative to height indicates higher health risk.
