Measuring your Body Mass Index (BMI)
Body mass index
Body mass index (BMI) is a measure you can use to see if you are a healthy weight for your height.
For most adults, an ideal BMI is in the 18.5-24.9 range.
If your BMI is 25 or more, you weigh more than is ideal for your height:
- 25-29.9 is overweight
- 30-39.9 is obese
- 40 or more is very obese
If your BMI is less than 18.5, you weigh less than is ideal for your height.
