FAQs
What is BMI?
Body Mass Index is weight in kilograms divided by height in metres squared. It's a quick screening measure used worldwide to categorise weight relative to height.
What are the BMI categories?
Under 18.5 is underweight, 18.5–24.9 is the healthy range, 25–29.9 is overweight, and 30 or above is obese (WHO cut-offs for adults).
Is BMI accurate for everyone?
Not perfectly — it doesn't distinguish muscle from fat, so athletes may score high while being very fit. Treat it as a rough guide, not a diagnosis, and talk to a doctor for health decisions.
