The body mass index (BMI) is a measure of body fat based on height and weight that applies to both men and women between the ages of 18 and 65 years. BMI can be used to indicate if you are overweight, obese, underweight or normal. A high BMI can be an indicator of high body fatness. BMI is not used to directly measure body fat. For example, a man and a woman could both have a BMI of 30. However, the man would likely have more muscle mass and less body fat than the woman. Therefore, BMI may not accurately reflect the amount of body fat for some people. The following BMI chart for women can help you determine if you are overweight, obese, underweight or normal:
What is BMI?
The Body Mass Index (BMI) is a measurement that uses your height and weight to estimate how much body fat you have. BMI can be used to screen for weight categories that may lead to health problems but it is not diagnostic of the amount of body fat.
For most people, BMI is a good estimate of body fat. However, BMI may overestimate body fat in athletes and people who have a muscular build. For these people, other methods may be used to measure body fat.
To calculate your BMI, divide your weight in kilograms by your height in meters squared. You can also use our BMI calculator.
BMI = Weight (kg) ÷ Height2 (m)
Or use this calculator.
What is a healthy BMI for women?
A healthy BMI for women is a BMI that falls between 18.5 and 24.9. A woman with a BMI of 18.5 or below is considered underweight, while a woman with a BMI of 25 or above is considered overweight. A healthy BMI falls within the range of 18.5 to 24.9. If your BMI is outside of this range, it does not necessarily mean that you are unhealthy—there are many factors that affect your health, including your diet and lifestyle choices. However, if you are outside of the healthy BMI range, it is important to talk to your doctor about ways to improve your health.
