Skinfold thickness measurements: Many experts use this simple method to determine body composition.However, these DEXA machines have limitations and the technology that is widely used is unable to measure the bones in people who weigh 300 pounds or more or who are taller than 6 feet. Dual-energy x-ray absorptiometry (DEXA): This is an x-ray scan that measures a person's bones (specifically their mineral density and bone loss) to calculate the possibilities of developing osteoporosis.Some body fat scales for home use employ this method of measurement. While readings can be affected by hydration level and other factors, they provide fairly accurate results over time. Bioelectrical impedance: This common method of assessing body fat percentage determines total body weight, the percent and amount of body fat, muscle mass, water, and even bone mass.For that kind of person with more muscle mass than ordinary people, the fat-free mass index is a much better, much more effective choice. Note that for somebody who exercises daily or trains professionally, BMI is mostly useless.

To interpret your result, compare it with the normal BMI range for women, which reads 18.5-25. Apply the BMI formula: BMI weight / height². The weight must be in kilograms and height in meters. On the other hand, body mass index (BMI) is a general estimation of your health that works well for most of the population. To calculate female BMI, follow these steps: Determine youre weight and height. This difference allows FFMI to estimate somebody's body and health condition correctly. If the mass of fat increases, the FFMI goes down, and if the mass of muscle increases, FFMI rises. That is where the fat-free mass index comes in with a solution.įFMI is defined in a way that allows distinguishing between fat gain and muscle gain. Both situations mean the same from BMI's viewpoint – weight increase results in a BMI index increase. On the other hand, it is a good thing when an athlete (or fitness enthusiast) puts on weight because of increased muscle mass. When somebody gains weight, caused by fat tissue increase, that usually means the person has become less healthy. From another point of view, an inactive person who does not exercise and is in an unhealthy state might get a perfect BMI result. The formula used to calculate BMI for men and women (Adults) is weight in kilograms divided by height in meters squared.

BMI screens for weight categories that may lead to health problems, but it does not diagnose the body fatness or health of an individual. A high BMI can indicate high body fatness. Somebody with a lot of muscle mass can be classified negatively – as overweight or even obese.Īs described in our BMI (body mass index) calculator, the BMI method is based only on weight, and therefore it doesn't take into account the difference in tissues and body type. Body Mass Index (BMI) is a person’s weight in kilograms (or pounds) divided by the square of height in meters (or feet). For example, people with different heights and weights can have the same BMI, even though they have different amounts of fat and muscle. Maybe, at first glance, it doesn't seem that big a problem, but the critics of BMI are justified. Input your height in either feet and inches or centimeters. Choose the measurement system (imperial or metric) 2. To calculate your ideal body weight using our IBW calculator, complete the following simple steps: 1. However, this method has its limitations, the most significant being that it doesn't take into account the weight of your lean muscle mass and your amount of body fat. The calculator employs the most well-known equations to calculate your IBW. The results are classified according to the defined norms, and thanks to that, you can say whether your weight is ideal or normal or if you are overweight or even obese (see ideal body weight calculator). Body mass index is a parameter calculated from your weight and height.
