Frequently Asked Questions
The calculator multiplies the square of your height in meters by the standard BMI thresholds of 18.5 and 24.9 to get the minimum and maximum weight (in kilograms) considered within the normal BMI range for your height.
The BMI calculator takes your weight and height and tells you which BMI category you fall into, while this tool works backwards from your height alone to show you the full weight range that would keep you in the "Normal" BMI category.
The calculator requires a height greater than zero. If the field is blank, zero, or negative, it shows an "Invalid input!" message instead of a weight range.
The range is a general population guideline based on BMI and doesn't account for muscle mass, age, or body frame, so it's for general informational purposes only and not a substitute for professional medical advice.
