BMI Calculator
Calculate Body Mass Index (BMI) from your weight and height.
Frequently Asked Questions
- What is BMI and what does it measure?
- BMI (Body Mass Index) is your weight divided by the square of your height, used as a quick screening measure to categorize body weight relative to height across a population.
- What BMI range is considered healthy?
- The commonly used ranges are: below 18.5 underweight, 18.5-24.9 normal weight, 25-29.9 overweight, and 30 or above obese — though these thresholds were developed for general adult populations and don't fit everyone equally well.
- Does BMI account for muscle mass?
- No — BMI can't distinguish muscle from fat, so muscular individuals (e.g. athletes) often show a higher BMI despite having low body fat. It's a useful screening tool, not a diagnosis.
