About Skinfold Body Fat Calculator (Durnin & Womersley)
How It Works
This calculator uses the Durnin & Womersley method published in 1974, which estimates body density from four skinfold measurements. The sum of skinfolds is logarithmically transformed and plugged into age- and gender-specific regression equations to estimate body density. The Siri equation then converts density to body fat percentage.
How to Interpret Results
Body fat percentage ranges vary by age, gender, and fitness level. For men, 10-20% is generally healthy, while women typically have 18-28%. Athletes often have lower body fat, while higher percentages may indicate increased health risk. Use the category labels as a general guide.
Measurement Tips
Take all measurements on the right side of the body with the subject standing. Pinch the skinfold firmly and place the caliper perpendicular to the fold. Read the measurement 2 seconds after releasing the caliper trigger. Take each site 2-3 times and use the average.
