Frequently Asked Questions
Is BMI always accurate?
Not always. It doesn’t distinguish between muscle and fat. Athletes may have a high BMI despite having low body fat.
What is a healthy BMI range?
For most adults, a BMI between 18.5 and 24.9 is considered the healthy/normal weight range.
Can BMI be used for children?
Yes, but the interpretation is different. For children and teens, BMI is compared against age- and gender-specific growth charts (percentiles).
Should I rely only on BMI?
No. For a complete health assessment, also consider waist circumference, body fat percentage, and consult a doctor.
