Measuring body fat is the process of determining the proportion of fat to lean mass in the human body. Body fat is essential for human health, providing insulation, energy storage, and cushioning for organs. However, excessive body fat can increase the risk of chronic diseases such as heart disease, stroke, and type 2 diabetes.
There are a number of different methods for measuring body fat. One common method is skinfold calipers, which measure the thickness of skin and fat at several sites on the body. Another method is bioelectrical impedance analysis (BIA), which measures the resistance of the body to an electrical current. BIA is a quick and non-invasive method, but it can be less accurate than skinfold calipers.
Measuring body fat can be helpful for assessing overall health and fitness, and for tracking progress towards weight loss or muscle-building goals. If you are concerned about your body fat levels, talk to your doctor or a registered dietitian.
How to Measure Body Fat UK
Measuring body fat is an important aspect of assessing overall health and fitness. There are a number of different methods for measuring body fat, each with its eigenen advantages and disadvantages. Some of the most common methods include:
- Skinfold calipers
- Bioelectrical impedance analysis (BIA)
- Hydrostatic weighing
- Air displacement plethysmography
- Dual-energy X-ray absorptiometry (DEXA)
- Magnetic resonance imaging (MRI)
- Computed tomography (CT)
The choice of which method to use will depend on a number of factors, including the accuracy required, the cost, and the availability of the equipment. For most people, skinfold calipers or BIA are a good option. These methods are relatively inexpensive, easy to use, and provide a reasonably accurate estimate of body fat percentage.
Skinfold calipers
Skinfold calipers are a simple and inexpensive tool that can be used to measure body fat. They work by pinching a fold of skin and measuring its thickness. This measurement can then be used to estimate the percentage of body fat. Skinfold calipers are a relatively accurate method of measuring body fat, and they are often used by fitness professionals and researchers.
Skinfold calipers are an important component of how to measure body fat UK. They are a quick and easy way to get a reasonably accurate estimate of body fat percentage. Skinfold calipers are also relatively inexpensive, making them a good option for people who are on a budget.
There are a number of different types of skinfold calipers available. The most common type is the Lange caliper, which has two arms that are used to pinch the skin. Other types of calipers include the Harpenden caliper and the Slim Guide caliper. The type of caliper that you choose will depend on your budget and your needs.
To use skinfold calipers, you will need to pinch a fold of skin and measure its thickness. The most common sites for measuring skinfolds are the triceps, the biceps, the subscapular, and the suprailiac. Once you have measured the skinfolds, you can use a body fat calculator to estimate your body fat percentage.
Bioelectrical impedance analysis (BIA)
Bioelectrical impedance analysis (BIA) is a method of measuring body fat that is based on the principle that the electrical resistance of the body is related to its composition. Lean tissue conducts electricity better than fat tissue, so people with a higher percentage of lean tissue will have a lower electrical resistance. BIA devices measure the electrical resistance of the body by sending a small electrical current through the body and measuring the voltage that is produced. This measurement can then be used to estimate the percentage of body fat.
- Principle
BIA devices measure the electrical resistance of the body by sending a small electrical current through the body and measuring the voltage that is produced. This measurement can then be used to estimate the percentage of body fat.
- Accuracy
BIA devices are relatively accurate, but they can be affected by a number of factors, such as hydration status, body temperature, and the amount of food that has been consumed recently.
- Convenience
BIA devices are quick and easy to use, and they can be used in a variety of settings. This makes them a good option for people who want to track their body fat percentage over time.
- Cost
BIA devices are relatively inexpensive, making them a good option for people who are on a budget.
BIA is a valuable tool for assessing body composition. It is a quick, easy, and relatively inexpensive way to estimate body fat percentage. BIA devices can be used to track progress towards weight loss or muscle-building goals, and they can also be used to assess the risk of developing obesity-related diseases.
Hydrostatic weighing
Hydrostatic weighing is a method of measuring body fat that is based on the principle of buoyancy. When a person is submerged in water, the amount of water that is displaced is equal to the volume of the person’s body. By measuring the weight of the person in air and the weight of the person in water, it is possible to calculate the person’s body density. Body density can then be used to estimate body fat percentage.
Hydrostatic weighing is a very accurate method of measuring body fat, and it is considered the gold standard against which other methods are compared. However, hydrostatic weighing is also relatively expensive and time-consuming, which limits its use in clinical and research settings.
Despite its limitations, hydrostatic weighing remains an important tool for understanding the relationship between body fat and health. Hydrostatic weighing has been used to show that people with higher body fat percentages have an increased risk of developing obesity-related diseases, such as heart disease, stroke, and type 2 diabetes.
Hydrostatic weighing can also be used to track progress towards weight loss or muscle-building goals. By measuring body fat percentage over time, it is possible to see how changes in diet and exercise are affecting body composition.
Air displacement plethysmography
Air displacement plethysmography (ADP) is a method of measuring body fat that is based on the principle that the volume of air displaced by a person is equal to the volume of the person’s body. ADP devices measure the volume of air displaced by a person by enclosing the person in a sealed chamber and measuring the change in pressure inside the chamber. This measurement can then be used to estimate the person’s body fat percentage.
- Principle

Magnetic resonance imaging (MRI)
Magnetic resonance imaging (MRI) is a medical imaging technique that uses magnetic fields and radio waves to create detailed images of the inside of the body. MRI is a valuable tool for measuring body fat, as it can provide accurate measurements of both subcutaneous fat (the fat that is just below the skin) and visceral fat (the fat that surrounds the organs). This information can be used to assess overall health and fitness, and to track progress towards weight loss or muscle-building goals.
- Principle
MRI scanners use a strong magnetic field to align the protons in the body. Radio waves are then emitted, which cause the protons to resonate. The amount of time it takes for the protons to return to their original state is measured, and this information is used to create an image of the body.
- Accuracy
MRI is a very accurate method of measuring body fat. MRI scans can measure body fat percentage to within 1-2%.
