BMI Calculator

Body Mass Index (BMI) is weight in kilograms divided by height in metres squared. It is a quick screening tool: a BMI of 18.5–24.9 is considered normal. BMI does not distinguish muscle from fat, so athletes should also check body-fat percentage.

Frequently Asked Questions

What is a healthy BMI?
A BMI of 18.5–24.9 is classified as normal weight. Below 18.5 is underweight, 25–29.9 is overweight, and 30 or above is obese.
Is BMI accurate for athletes?
Not always. BMI does not separate muscle from fat, so muscular people can read as overweight. Athletes should also check body-fat percentage.
How do I lower my BMI?
Lower BMI by losing fat through a moderate calorie deficit and regular activity. The CaloNote BMI calculator shows the weight needed to reach a normal BMI.
