Best BMI Scales

Stepping onto a traditional bathroom scale doesn’t tell you much about your health and body composition. The scale knows nothing about how tall you are or how much muscle compared to fat you have on your frame. Without that context, your total body weight doesn’t mean much. Fortunately, the last few years has seen the introduction of BMI smart scales. These bathroom scales look just like your old scale but are able to provide you with a whole raft of information about your body composition. In this article, we reveal the 4 best BMI scales on the 2020 market.

How BMI Scales Work

BMI stands for body mass index. It is a measure of a person’s health that divides their weight in kilograms by the square of their height in meters. There are four weight categories based on BMI:

  • Underweight
  • Healthy weight
  • Overweight
  • Obese

The majority of BMI scales use a technology known as bioelectrical impedance analysis. An electrical current passes up your body and your body’s opposition to that current is measured. Because muscle, water and fat all oppose electrical currents at different rates, the system is able to work out your percentage of fat, muscle and water.

Most BMI scales pair with an app that allows you to analyze your body composition in detail.

How Accurate are BMI Scales?

BMI scales are not as accurate as the body composition tests you will get from your doctor. The most accurate form of testing is hydrostatic weighing. However, a good set of BMI scales will give you a good gauge of what your body composition figures are. It may not be accurate to the decimal point but the more important thing is to be able to track changes over time to get a precise reading of your body fat percentage.
