Frequently Asked Questions
What is a healthy BMI for my age and gender?
For adults over 20, a healthy BMI is between 18.5 and 24.9. This standard applies to both men and women. However, older adults (65+) may benefit from a slightly higher BMI (up to 27) for better health protection.
How is BMI calculated? (The Formula)
BMI is calculated by dividing your weight in kg by your height in meters squared (kg/m²). Our tool also supports imperial units (lbs/in²) using the professional multiplier of 703 for 100% accuracy.
How accurate is the WeightBMI for athletes?
BMI can overestimate body fat in athletes or individuals with high muscle mass because muscle is much denser than fat. In these cases, it should be used alongside other metrics like body fat percentage.
What are the WHO BMI categories?
The World Health Organization (WHO) classifies BMI as: Underweight (<18.5), Normal (18.5-24.9), Overweight (25-29.9), and Obese (≥30). Our calculator provides instant classification based on these official ranges.
Can BMI predict health risks?
Yes, a BMI outside the 'normal' range is often associated with increased risks of heart disease, type 2 diabetes, and hypertension, making it a vital screening tool for overall health.
