Introduction

Understanding your body composition is essential for maintaining overall health and fitness. The Skinfold Body Fat Calculator provides a simple, effective way to estimate your body fat percentage, lean body mass, and fat mass using seven key skinfold measurements.

This calculator is designed for both men and women. By entering your age, gender, weight in dollars $, and skinfold measurements, you can receive detailed insights into your body composition in real-time without needing multiple tools.

Using this calculator regularly can help track progress in fitness programs, monitor body fat changes, and maintain a healthy balance between muscle and fat.

How It Works

The Skinfold Body Fat Calculator works by measuring fat thickness at seven specific points on the body. These points are Chest, Abdomen, Thigh, Triceps, Subscapular, Suprailiac, and Midaxillary.

Each measurement is entered in either millimeters (mm) or centimeters (cm). The calculator uses these measurements to calculate your Body Density, which is then converted to Body Fat Percentage using the widely accepted Jackson & Pollock 7-site formula.

Once Body Fat % is calculated, Lean Body Mass and Fat Mass are derived using your weight. This allows a clear understanding of how much of your weight is fat versus muscle and other lean tissue.

• Chest skinfold measurement
• Abdomen skinfold measurement
• Thigh skinfold measurement
• Triceps skinfold measurement
• Subscapular skinfold measurement
• Suprailiac skinfold measurement
• Midaxillary skinfold measurement

Formula

The calculator uses the Jackson & Pollock 7-site formula to calculate body density. The formula differs slightly for men and women to account for physiological differences.

// Men:
        Body Density = 1.112 - 0.00043499*(Sum of 7 Skinfolds) + 0.00000055*(Sum of 7 Skinfolds)^2 - 0.00028826*Age

        // Women:
        Body Density = 1.097 - 0.00046971*(Sum of 7 Skinfolds) + 0.00000056*(Sum of 7 Skinfolds)^2 - 0.00012828*Age

        Body Fat % = (495 / Body Density) - 450

        Lean Mass = Weight - Fat Mass
        Fat Mass = Weight * (Body Fat % / 100)

Proper measurement technique is crucial for accurate results. Always pinch the skin without including underlying muscle, use consistent pressure, and measure on the right side of the body.

These categories help users understand where they fall in terms of body composition. Individuals aiming for performance or health goals can use these benchmarks to adjust fitness and nutrition programs.

Examples

Example 1: A 25-year-old male weighs 70$ and records skinfolds: Chest 12mm, Abdomen 20mm, Thigh 15mm, Triceps 10mm, Subscapular 12mm, Suprailiac 14mm, Midaxillary 13mm. Body Fat % calculated: 15%, Lean Mass: 59.5$, Fat Mass: 10.5$.

Example 2: A 30-year-old female weighs 60$ with skinfolds: Chest 18mm, Abdomen 22mm, Thigh 20mm, Triceps 15mm, Subscapular 17mm, Suprailiac 19mm, Midaxillary 16mm. Body Fat %: 28%, Lean Mass: 43.2$, Fat Mass: 16.8$.

Example 3: 40-year-old male, weight 90$, skinfolds measured accurately. Body Fat %: 22%, Lean Mass: 70.2$, Fat Mass: 19.8$.
