Your BMI
22.5 Healthy weight
A healthy weight for your height is about 53.5 kg to 72.0 kg.
BMI is a quick screening number for adults. It doesn’t account for muscle, age, sex or ethnicity, and isn’t a diagnosis. For children and teens, or if you’re pregnant, ask a doctor.
What is BMI?
Body Mass Index is your weight divided by your height squared (kg/m²). The World Health Organization groups adult BMI as underweight (below 18.5), healthy (18.5–24.9), overweight (25–29.9) and obesity (30 and above). Your numbers stay on your device.
Frequently asked questions
Is BMI accurate?
It is a rough screening number for adults. Very muscular people can score high while being healthy. It is not a diagnosis.
Can children use it?
No. Children and teens need age- and sex-specific growth charts; ask a doctor or nurse.
