Disclaimer: This calculator provides an estimated body fat percentage and is intended for general educational and fitness purposes. It is not a medical diagnosis. Individual results may vary because circumference-based calculations are affected by measurement technique, body shape and other factors. For a clinical assessment, consult a qualified healthcare professional or use a validated body-composition measurement method.

How Should You Measure Your Body?

• Use a flexible measuring tape.
• Keep the tape level and comfortably snug.
• Do not deliberately pull the tape tightly into the skin.
• Take measurements consistently each time.
• Measure under similar conditions when tracking changes.
• For the most reliable results, follow standardized measurement instructions.

What Is Body Fat Percentage?

Body fat percentage represents the proportion of your total body weight that consists of fat. It is different from BMI, because BMI does not directly distinguish between fat mass and lean body mass.

Is This Body Fat Calculator Accurate?

Circumference-based body fat calculations are useful estimates, but they are not equivalent to a clinical body-composition test. Measurement technique and individual body shape can affect the result. The U.S. Navy's body-composition guidance also describes circumference-based body-fat values as estimates.

Body Fat Percentage vs BMI

BMI uses height and weight to classify weight status, while body fat percentage attempts to estimate the proportion of body weight that is fat. For fitness tracking, looking at multiple measures rather than relying on one number can provide a more useful picture of body composition.

Frequently Asked Questions

Can I calculate body fat without a measuring tape?

A circumference-based calculator requires measurements such as neck and waist circumference. Other methods, such as DEXA, bioelectrical impedance and skinfold testing, use different techniques.

Should I use the result as a medical diagnosis?

No. This calculator is intended for general educational and fitness purposes. If you have concerns about your body composition, weight or health, speak with a qualified healthcare professional.
