What is BMI for Men?

The BMI formula is the same for adult men and women. However, men often have higher muscle mass, which can affect how BMI should be interpreted.

BMI Formula for Men

Metric: BMI = weight (kg) ÷ height² (m²)

Imperial: BMI = (weight (lbs) ÷ height² (in²)) × 703

Can BMI Be Misleading for Men?

Yes. Men with higher lean muscle mass may have a BMI in the overweight range despite having relatively low body fat.

Frequently Asked Questions

The Body Mass Index (BMI) is a screening tool used to identify whether an adult is underweight, at a healthy weight, overweight, or obese. It is calculated by dividing a person’s weight in kilograms by the square of their height in meters.

The formula is the same, but interpretation can differ because men often have greater muscle mass.

Yes. BMI does not distinguish muscle from fat, so muscular men may have higher BMI values without excess body fat.

For most adult men, a BMI between 18.5 and 24.9 is considered healthy.
