About the BMI Calculator

The BMI Calculator computes your Body Mass Index from your height and weight, shows your healthy weight range, and tells you which BMI category you fall into β€” a quick screening tool for weight relative to height.

Frequently Asked Questions

How is BMI calculated?

BMI equals your weight in kilograms divided by your height in meters squared (kg/m2). The calculator handles metric or imperial units and does the math for you.

What is a healthy BMI range?

For most adults, a BMI of 18.5-24.9 is considered healthy, 25-29.9 is overweight, 30 and above is obese, and below 18.5 is underweight. The tool shows your category and healthy weight range.

Is BMI accurate for everyone?

BMI is a useful general screen but does not distinguish muscle from fat, so it can misclassify very muscular people and can vary by age and ethnicity. Treat it as one indicator, not a diagnosis.

Is this medical advice?

No. BMI is a screening tool only β€” consult a healthcare professional for personal health guidance.
