Questions
How is BMI calculated?
Weight in kilograms divided by height in meters squared. 72 kg at 1.75 m is 72 ÷ 1.75² = 23.5.
What is a healthy BMI?
For adults, the World Health Organization calls 18.5 to 24.9 a healthy weight, 25 to 29.9 overweight and 30 or more obesity.
Is BMI accurate for everyone?
No. It doesn’t tell muscle from fat, so very muscular people can score as overweight, and it doesn’t show where fat is carried. For children and teens, age-and-sex charts are used instead.
Is it free? Do I need an account?
It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
