What is BMI?
BMI (Body Mass Index) is a simple numerical value calculated from your height and weight. It helps determine whether a person is underweight, at a healthy weight, overweight, or obese. Healthcare professionals often use BMI as a screening tool to identify potential weight-related health risks. Although it does not directly measure body fat, it provides a quick and reliable general assessment for most people.

BMI Formula
The BMI formula used to calculate BMI is:
BMI = Weight (kg) ÷ Height² (m²)
For example, if a person weighs 70 kg and is 1.75 meters tall:
BMI = 70 ÷ (1.75 × 1.75) = 22.86
This value falls within the normal weight category. Use our BMI table or BMI chart women to see the full range of categories.

Why BMI is Important
BMI is important because it provides a quick overview of your weight status and associated health risks. Individuals with higher BMI values may face increased risks of heart disease, type 2 diabetes, high blood pressure, and other chronic conditions. Being underweight can also indicate nutritional deficiencies or underlying health concerns.
Regularly monitoring your BMI with our BMI calculator female, male or general tool can help you make informed decisions about diet, exercise, and lifestyle habits.
Limitations of BMI
While BMI is a useful screening tool, it doesn’t distinguish between muscle and fat. Athletes or highly muscular individuals may have a high BMI but low body fat. Always consult a healthcare professional for a comprehensive health assessment.
Tips to Maintain a Healthy BMI
Maintaining a healthy BMI involves adopting sustainable lifestyle habits:
- Eat a balanced diet rich in vegetables, fruits, whole grains, lean proteins, and healthy fats.
- Combine this with regular physical activity, including cardio and strength training.
- Avoid extreme dieting or rapid weight-loss methods.
Gradual improvements and consistent healthy routines will support long-term wellness.
