Each entry is the thickness of a pinched fold of skin and underlying fat\u2014not the circumference of that body part. The calculator requires all seven sites; leaving one out changes the sum and makes the estimate unreliable.<\/p>\n<h2>What the results mean<\/h2>\n<p>Body fat percentage estimates the proportion of your total weight that is fat. The Jackson\u2013Pollock 7-site method uses folds from the chest, abdomen, thigh, back of the upper arm, below the shoulder blade, above the hip, and side of the torso. These measurements estimate body density; a second equation converts density into a body fat percentage.<\/p>\n<p>Lean body mass is your estimated weight minus estimated fat mass. It includes muscle, but also water, bones, organs, and other non-fat tissue. For example, the 64.02 kg result above does <em>not<\/em> mean the person has 64.02 kg of muscle. Because lean body mass depends on the estimated body fat percentage, an error in the skinfold estimate also affects the lean mass result.<\/p>\n<p>These results can be useful for following changes over time alongside weight and other measurements. A single percentage is not a diagnosis or a complete picture of health: the method does not show where internal fat is stored or distinguish changes in muscle from changes in body water. For a different measure based on height and weight, use the <a href=\"https:\/\/wpcalc.com\/en\/beauty\/body-mass-index\/\">Body Mass Index calculator<\/a>. For another body fat estimate that does not require calipers, see the <a href=\"https:\/\/wpcalc.com\/en\/beauty\/circumference-bodyfat\/\">Circumference Bodyfat calculator<\/a>.<\/p>\n<h2>Measurement tips and limitations<\/h2>\n<p>Skinfold technique matters. Use the same established site locations and measurement procedure each time. Pinch the skin and underlying fat without including muscle, place the calipers beside your fingers, and take repeat readings at each site. If readings differ noticeably, repeat them rather than relying on one attempt. A trained measurer can help improve consistency, especially at sites that are difficult to reach yourself.<\/p>\n<p>For comparisons over time, measure under similar conditions and, where possible, have the same person use the same calipers. Hydration, recent exercise, site placement, and differences between measurers can all affect readings. Look for a sustained trend rather than treating a small change in the displayed percentage as a precise change in body fat.<\/p>\n<p>This calculator uses the <strong>men\u2019s<\/strong> Jackson\u2013Pollock equation; the <a href=\"https:\/\/wpcalc.com\/en\/beauty\/body-mass-for-women\/\">Body Mass for Women calculator<\/a> uses a different equation. Although the Age field accepts values from 10 years upward, an accepted input is not a guarantee that this equation is appropriate for children or adolescents. Estimates may also be less reliable when skinfolds do not reflect overall body fat well. If you need an assessment for a clinical or athletic decision, discuss the measurement method and result with a qualified professional.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Estimate body fat percentage and lean body mass with the Jackson\u2013Pollock 7-site method for men.
