What is BMI?
Body Mass Index (BMI) is a simple calculation that uses your height and weight to determine if your weight is in a healthy range. It is a widely used screening tool by healthcare professionals to identify potential health risks associated with being underweight or overweight. Note that BMI is an estimate and does not directly measure body fat or muscle mass.
How to Use the BMI Calculator

Understanding Your BMI Results
- Under 18.5: Underweight (May indicate nutritional deficiency)
- 18.5 – 24.9: Healthy Weight (Lowest health risk)
- 25.0 – 29.9: Overweight (Increased risk of heart disease)
- 30.0 and Above: Obese (High health risk)
Important Limitations of BMI
BMI is not a perfect measure. It does not distinguish between muscle and fat. For example, an athlete with high muscle mass might have a high BMI but is actually very healthy. Conversely, older adults who have lost muscle mass might have a normal BMI despite having excess body fat. Always consult a doctor for a complete health assessment.
Frequently Asked Questions (FAQs)
Is BMI accurate for children and teens?
No. BMI for children and teens is calculated differently using percentiles because their body composition changes as they grow.
Does BMI differ by gender?
The standard BMI formula is the same for both men and women. However, women naturally tend to have more body fat than men at the same BMI.
