Frequently asked questions
What is a healthy BMI range?
For most adults, a BMI between 18.5 and 24.9 is considered a normal weight range, though this tool is a general guide, not medical advice.
Is BMI accurate for everyone?
BMI does not account for muscle mass, bone density, age, or sex, so athletes and some other groups may see results that do not reflect their actual body composition.
Which units can I use?
You can switch between metric (kilograms and centimeters) and imperial (pounds, feet, and inches) using the toggle above the form.
