BMI (Body Mass Index) is a measure of body fat based on height and weight. It is calculated by dividing weight (in kg) by height (in meters) squared. BMI is a useful screening tool for weight categories.
According to WHO standards: Underweight (< 18.5), Normal (18.5 – 24.9), Overweight (25 – 29.9), and Obese (≥ 30). Our calculator uses these standard ranges.
BMI is a general screening tool but may not be accurate for athletes with high muscle mass, pregnant women, or elderly individuals. It's best used as a starting point for health assessment.
A healthy BMI range for adults is between 18.5 and 24.9. However, this can vary based on age, gender, and ethnicity. Always consult a healthcare professional for personalized advice.
BMI for children is calculated differently using age and gender-specific percentiles. Our calculator is designed for adults (age 18+). For children, consult a pediatrician.
BMI is an important indicator of health risks. High BMI is associated with increased risk of heart disease, diabetes, and other health conditions. Maintaining a healthy BMI is beneficial for overall wellbeing.
