BMI Calculator

Calculate your Body Mass Index (BMI) from height and weight.

💡 How to Use

Enter your height (cm) and weight (kg), then click 'Calculate' to see your BMI value along with its category: underweight, normal, overweight, or obese. Results follow WHO guidelines (under 18.5 underweight, 18.5–24.9 normal, 25 and above overweight), giving you an instant snapshot of your weight status. Use it for setting diet goals, doing a pre-checkup self-assessment, or tracking weight management progress. Note that BMI does not account for muscle mass, so treat it as a guide and consult a healthcare professional for an accurate health assessment.

FAQ

What is the normal BMI range?
The WHO standard is 18.5-24.9 for normal weight. For Asians, 18.5-22.9 is normal, and 23+ is considered overweight.
Does a high BMI always mean obesity?
No. BMI doesn't directly measure body fat, so muscular athletes may have a high BMI without being obese.
Is BMI calculated the same for children?
The formula is the same, but interpretation differs. Children use age- and sex-specific percentiles, not adult BMI categories.
