Frequently Asked Questions
BMI (Body Mass Index) is a measure of body fat based on your weight in relation to your height. It's a simple screening method to identify potential weight problems in adults.
BMI is a useful screening tool but it doesn't directly measure body fat. It may overestimate body fat in athletes and underestimate it in older people who have lost muscle mass. For most people, it provides a good estimate of weight-related health risks.
For adults, a BMI between 18.5 and 24.9 is considered healthy. This range is associated with the lowest risk of health problems related to weight.
BMI is calculated differently for children and teens. It's age and sex-specific and referred to as BMI-for-age. This calculator is designed for adults only.
For most adults, checking your BMI every 3-6 months is sufficient unless you're actively trying to lose or gain weight. Significant changes in BMI may warrant consultation with a healthcare provider.
