Loona Calculators
Enter your weight and height to learn whether your weight is in the healthy range — underweight, normal, overweight or obese. Height can be entered in centimetres or in feet and inches.
For adults, 18.5 to 24.9 is the normal range. Below 18.5 is underweight, 25–29.9 overweight, and 30+ obese.
BMI is a general guide. Muscular athletes can show a high BMI without excess fat — consult a doctor for a full assessment.
This calculator uses the adult scale. Children's BMI is read on age-based charts.
