Frequently Asked Questions
Pro Tips
BMI does not distinguish between muscle and fat — athletes routinely register as "overweight." Use BMI alongside waist circumference and body fat percentage for a complete picture.
Waist-to-height ratio (waist ÷ height) below 0.5 is a strong predictor of metabolic health — often more useful than BMI for assessing cardiovascular risk.
Asian populations have higher metabolic risk at lower BMI values. Some clinicians use BMI ≥23 as overweight for Asian adults, not the WHO standard of 25.
Track your BMI trend over months, not as a single snapshot. A consistent downward trend matters far more than hitting a specific number on any given day.
When to Use This Calculator
Calculate your BMI as part of your annual health self-assessment alongside blood pressure and cholesterol.
Find the BMI-normal weight range for your height to set a realistic, medically-recognised target weight.
Check whether BMI is in the healthy range before conceiving — optimal range reduces pregnancy complications.
Monitor BMI monthly during a training program — though note athletes may show high BMI despite low body fat.
Calculate your BMI in advance so you can have an informed conversation about your weight with your healthcare provider.
