🧮 How to Calculate Body Fat Percentage (For Men & Women)

Knowing your body fat percentage helps you understand your fitness level better than weight or BMI alone.
Follow this simple method to calculate it at home — works for both men and women!

📏 What You’ll Need

A measuring tape (cloth or tailor’s type)
A calculator or phone
A few minutes and honest measurements

🧔 For Men — Measurements Needed

Height (without shoes)
Neck circumference (just below Adam’s apple)
Waist circumference (at the navel or narrowest point of torso)

Formula (U.S. Navy Method):

Body Fat % = 86.010 × log10(waist - neck)

           - 70.041 × log10(height)

           + 36.76

Example:
Height: 70 in
Neck: 15 in
Waist: 34 in

👉 Result ≈ 17.5% Body Fat

👩 For Women — Measurements Needed

Height
Neck circumference
Waist circumference
Hip circumference (at widest part of hips/buttocks)

Formula (U.S. Navy Method):

Body Fat % = 163.205 × log10(waist + hip - neck)

           - 97.684 × log10(height)

           - 78.387

Example:
Height: 64 in
Neck: 13 in
Waist: 28 in
Hip: 38 in

👉 Result ≈ 26.6% Body Fat

✅ Tips for Accurate Results

Measure at the same time each day (morning is best).
Keep the tape snug but not tight.
Use the same units (inches or cm).
Repeat 2–3 times and take the average.
Track changes monthly, not daily.

🧠 Remember

This method gives a good estimate, not an exact medical reading.
For high accuracy, get tested by a DEXA scan, hydrostatic weighing, or Bod Pod.
