Calculate your body mass index in metric (cm, kg) or US (feet, inches, pounds) units and see the healthy weight range for your height.
BMI is your weight in kilograms divided by your height in meters squared. In US units it is weight in pounds × 703 ÷ height in inches squared. This calculator converts for you.
| BMI | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 to 24.9 | Normal weight |
| 25 to 29.9 | Overweight |
| 30 and above | Obesity |
BMI is a quick screening number. It does not measure body fat, muscle, bone density or where fat is carried, so it can mislead for athletes, older adults and some ethnic groups. The categories above are for adults and do not apply to children, who use age-based charts.
For most adults a BMI from 18.5 to 24.9 is considered the normal range.
Not always. Muscle weighs more than fat, so muscular people can have a high BMI without excess body fat.
No. Children and teenagers use BMI-for-age percentile charts.
