BMI Calculator

BMI calculator: enter height and weight (imperial or metric) to find your Body Mass Index and category.

Body Mass Index (BMI) is a simple, widely used screening measure that relates height and weight to estimate whether your weight is in a healthy range. It's a starting point for awareness and does not replace medical advice.

Frequently asked questions

What is a healthy BMI range?

According to the CDC and WHO, a healthy BMI is 18.5 to 24.9. Below that is underweight, 25 to 29.9 is overweight, and 30 or more is classified as obese.

Is BMI accurate for athletes?

Not always. BMI doesn't distinguish muscle from fat, so a muscular athlete may fall into the 'overweight' range while being perfectly healthy. Pair it with other measures like body-fat percentage.
