How do I know if I have a healthy body weight?
A healthy body weight is different for everyone. If you're not sure what's healthy for you, check with your doctor.
What is BMI?
The body mass index (BMI) is a tool that can help healthcare professionals decide when adults may be at risk for developing health problems because they are underweight or overweight. The BMI uses a chart based on height and weight.
Enter your height and weight below to find your BMI. Be sure to use a scale and measuring tape for these measurements – don't estimate.
This BMI tool is for adults over 18. Pregnant or breastfeeding women should not use this tool.
|Your BMI is:|
What your BMI means
|less than 18.5||underweight|
|18.5 to 24.9||normal weight|
|25 to 29.9||overweight|
|30 or more||obese|
The BMI isn't perfect
While there are some drawbacks to using the BMI as a tool to measure healthy body weight, it is still a helpful tool when talking about weight and goals with your doctor. Some things to remember:
- The BMI calculation uses weight and height to estimate – not exactly measure – body fat.
- BMI and body fat are different for men and women.
- BMI may not reflect the changes to body fat and muscle mass that happen as people age.
- Lean people with high muscle mass, such as athletes, may have high BMI scores.
