Estimate body fat percentage from three skinfold measurements using the Jackson-Pollock formula.
How It Works
How Skinfold Body Fat Calculator (Jackson-Pollock 3-Site) Works
The three skinfold measurements are added together and combined with age using the Jackson-Pollock regression equation (a different formula for men and women, reflecting different typical fat distribution patterns) to estimate body density, which is then converted into a body fat percentage using the Siri equation.
FAQ
Frequently Asked Questions
Which three sites should I measure?
For men, the standard sites are chest, abdomen, and thigh; for women, they're triceps, suprailiac (just above the hip bone), and thigh — using a proper skinfold caliper and consistent technique matters more for accuracy than almost any other factor here.
How accurate is skinfold testing compared to other methods?
In experienced hands it's a solid, inexpensive estimate, but accuracy depends heavily on measurement technique and consistency — results can vary noticeably between different testers, so tracking your own trend over time with the same tester matters more than comparing a single reading against someone else's.
