BMI Calculator

Question 1

What is a healthy BMI range?

Answer

A BMI between 18.5 and 24.9 is considered a normal or healthy weight range. Below 18.5 is underweight, 25 to 29.9 is overweight, and 30 or above is obese. These ranges apply to most adults but may vary for athletes, older adults, and certain ethnic groups.

Question 2

Is BMI an accurate measure of health?

Answer

BMI is a useful screening tool but has limitations. It does not distinguish between muscle and fat mass, so muscular individuals may have a high BMI without having excess body fat. It also does not account for fat distribution, age, sex, or ethnicity. Use BMI as a general guideline alongside other health indicators.

Question 3

What is the BMI formula?

Answer

The BMI formula is: weight (kg) / height (m)². For imperial units: (weight in lbs / height in inches²) × 703. Our calculator handles both systems automatically.

Question 4

Can BMI be used for children?

Answer

BMI for children and teens uses percentile rankings based on age and sex, rather than fixed categories. A child's BMI is compared to others of the same age and sex. This calculator is designed for adults aged 18 and over.

Question 5

What should I do if my BMI is outside the normal range?

Answer

If your BMI is outside the normal range, consult a healthcare professional for a comprehensive health assessment. They can evaluate your overall health, body composition, and risk factors more thoroughly than BMI alone.

Question 6

What is a healthy BMI range?
