a 3-Point Skinfold Body Fat Calculator is a tool that can accurately estimate your body fat percentage based on skinfold measurements taken from three different locations on the body and potentially assess your health and fitness level. The method has been developed Jackson & Pollock in the late 1970s and has since become one of the most widely used methods for determining body composition.
The basic idea behind this technique is that by measuring the thickness of the skin fold at specific locations, you can estimate how much subcutaneous fat (the fat under the skin) a person has. This information can then be used to calculate your total body fat percentage using an equation that takes into account age, gender and other factors.
A 3-point skinfold test is often performed calibers, which are hand-held devices built specifically for this type of measurement. The test involves squeezing and pulling together folds of skin at specific points on the body.
This method is the most widely used of all the other methods in the fitness industry. it’s free and can measure your body composition fairly accurately (with a standard error of 3.5%, depending on the equation used, compared to a 2.7% error for hydrostatically estimated measurements). It is also quite simple to perform once the trainer has the ability to pinch the skin and measure it with skinfold calipers.
In this blog post, we’ll explore what the 3-Point Skinfold Body Fat Calculator is, how it works, and how to perform an accurate test. Get ready to learn everything you need to know about this popular way to measure body fat.

What is the 3-point skin test?
a 3-Point Skin Fold Test is a method used to measure body fat percentage skinfold thickness with caliber in three different places on the body. This test is based on the principle that the amount of subcutaneous adipose tissue or adipose tissue is directly related to total body fat.
The 3-point skinfold test measures skinfolds in common fat areas such as the chest, abdomen, and thighs. for menand hamstring, triceps, and suprailiac women. These areas were chosen because they contain significant amounts of subcutaneous adipose tissue and are less affected by changes in muscle mass.
The 3-Point Skinfold Test is easy to administer and requires no expensive equipment, making it accessible to personal trainers, coaches, or anyone interested in tracking their fitness progress.
How to do an accurate 3-point skin test?
Performing a 3-point skinfold test to calculate body fat percentage requires precision and accuracy. Here’s how to perform an accurate 3-point skinfold test:
First, make sure the person being tested is rested and has not exercised for at least an hour before the test. The tester should also make sure they clean and dry their hands before they start.
Next, find the three common areas of fat accumulation where measurements will be taken: chest, abdomen, and thighs for men, and thighs, triceps, and upper thighs for women.
Certain factors can affect these measurements, making the calculations inaccurate. These factors include age, moisture and skin firmness. Some people tend to have tighter skin, making it almost impossible to pinch, while others find it much easier. For those with very tight skin, it would be better to use other options.
For each skinfold zone, pinch the skin with your thumb and forefinger while keeping it perpendicular to the underlying muscle fibers. Be sure to grab enough tissue for an accurate measurement, but not so much that you include the underlying muscles or bones.
Using calipers, measure the thickness in millimeters at each location. Wait a few seconds between each measurement. Take three readings at each site and average them for more accurate results. To ensure consistency, measurements should be taken on the right side of the body unless there is an injury or surgery affecting only one side.
It is important to note that the results obtained from this calculation may not be as accurate as with more sophisticated methods such as hydrostatic weighing, but it provides a reasonable approximation for most people.
Where to take skinfold measurements?
Knowing the exact locations of skinfold measurements is the key to getting accurate results.
Here is a summary of both men’s and women’s measurement locations:
Measurement location for men
- Pectoral (mm) – This measurement is taken above the nipple, vertically in line with the armpit, providing an accurate estimate of chest area. Pinch the fold of skin between your thumb and forefinger to get an accurate reading
- Stomach (mm) – For this measurement, press the skinfold vertically approximately one inch to the right of the belly button to accurately determine the thickness.
- hip (mm) – For hip measurement, place the clamps between the thigh and the knee, on the front of the thigh. Press the skin fold vertically to ensure accurate results
Measurement site for women
- Tricep (mm) – Tricep measurement is taken at the back of the upper arm. Place the snaps halfway between the shoulder and the elbow. Press the skinfold vertically to get an accurate reading.
- Suprailiac: (mm) – To obtain this measurement, place the site approximately 1-2 cm above the femur, in line with the natural angle of the femoral crest. Cut the skin fold diagonally, providing a firm grip for accurate measurement.
- hip (mm) – Similar to men, the hip measurement for women is taken at the front of the thigh, between the hip and the knee. Press the skin fold vertically, ensuring a firm grip for accurate results.
By taking accurate readings from each of these locations, you can get an overall rough estimate of body fat percentage that will be useful when monitoring changes in health or weight loss goals over time.
3-Point Skinfold Body Fat Formula
It 3-Point Skinfold Body Fat Formula used to calculate body fat percentage based on skinfold measurements from three specific body areas. This the resolution developed by Arthur K. Jackson and Michael L. by Pollock, two exercise physiologists who conducted extensive research on human anatomy and body composition.
Below are the formulas for both male and female.
Body density = 1.10938 – (0.0008267 x skinfold sum) + (0.0000016 x skinfold sum squared) – (0.0002574 x age)
Body density = 1.0994921 – (0.0009929 x skinfold sum) + (0.0000023 x skinfold sum squared) – (0.0001392 x age)
After deciding yours body densityyou can use it to calculate body fat percentage using Siri’s equation:
Body fat percentage = ((4.95 / body density) – 4.50) x 100
Body fat percentage norms for men and women
It 3-Point Skinfold Body Fat Calculator created by Jackson & Pollock is an effective tool for measuring body fat percentage. By following the steps in this article and using the appropriate formula for your gender, you can get a fairly accurate estimate of your body fat percentage.
However, it is important to remember that no measurement method is perfect and there are always limitations to consider. Other factors such as hydration levels, age, fitness level and general health should also be considered when assessing body composition.
The 3-Point Skinfold Body Fat Calculator can be a useful tool for tracking body composition changes over time and setting realistic goals for weight loss or muscle gain. Just remember to use it as part of a comprehensive health and wellness approach that includes regular exercise, healthy eating habits, and self-care practices.
