Understand your BMI result
BMI is a quick screening number based on height and weight. It can help start a health conversation, but it does not measure body fat directly.
Results are for general information. Review the site disclaimer before using a result for an important decision.
What BMI measures
BMI divides weight in kilograms by height in meters squared. The result is grouped into common categories such as underweight, healthy range, overweight, and obesity.
It is useful for broad screening, but it does not account for muscle mass, body composition, age, or medical conditions.
When to use BMI carefully
Athletes, pregnant people, children, older adults, and people with specific medical conditions may need a more personalized assessment.
Use BMI as general information only. For health decisions, speak with a qualified medical professional.
What to do with a BMI result
A BMI result can be a starting point for a broader conversation about health habits, nutrition, activity, or screening. It does not describe your overall health by itself.
If you are concerned about a result, seek advice from a qualified healthcare professional who can consider your history, symptoms, and other measurements.
