3-Point Skin Fold Bodyfat
This calculator estimates your body fat percentage and lean body mass using the Jackson-Pollock 3-point skinfold method. It requires your weight, age, and measurements at three skinfold sites. Ideal for fitness tracking, it's widely used due to its simplicity and fair accuracy, though it may underestimate fat in very lean individuals.

3-Point Skinfold Body Fat Formula
Where:
- $$xā$$, $$xā$$, $$xā$$ are the skinfold thicknesses (in mm)
- $$A$$ is age
- $$cā$$, $$cā$$, $$cā$$ are constants that differ for men and women.
The Jackson-Pollock 3-point method uses caliper measurements at specific body sites to estimate body fat. For men, the typical sites are chest, abdomen, and thigh; for women, triceps, suprailiac, and thigh. While convenient and widely used in gyms, results depend on proper technique and calibration. The calculator also estimates lean body mass by subtracting fat mass from total weight.
