Frequently Asked Questions
How do I calculate BMI for men?
Divide weight in kilograms by height in meters squared; the same formula applies to men and women.
What is a healthy BMI for men?
18.5 to 24.9 is the standard healthy range, but muscular men may read higher without excess fat.
Does BMI account for muscle?
No. Very muscular men can be classified as overweight by BMI despite low body fat, so use it alongside other measures.
