How it works
BMI is your weight in kilograms divided by your height in metres squared.
For adults the World Health Organization groups results as underweight (under 18.5), healthy (18.5 to 24.9), overweight (25 to 29.9) and obese (30 and above).
BMI cannot tell muscle from fat, so people who lift can score high while having low body fat.
Questions
Is BMI accurate for bodybuilders?
Not really. Muscle is dense, so muscular people often fall in the overweight range. Body fat percentage is a better measure for them.
What is a healthy BMI?
For most adults, 18.5 to 24.9 is considered the healthy range, but health also depends on fitness, diet and waist size.
Can I use this for children?
No. This calculator is for adults aged 18 and over. Children and teens use age and gender based charts.
