Find out your BMI category and how much weight you would need to lose to reach the normal BMI range.
This tool estimates whether your current weight falls into the overweight category based on your height, using standard BMI (Body Mass Index) classification ranges. It's intended as a general screening reference, not a diagnostic medical tool.
BMI = Weight (kg) ÷ Height (m)². Standard BMI categories: Underweight (below 18.5), Normal weight (18.5–24.9), Overweight (25–29.9), Obese (30 and above). These ranges are general population guidelines and don't account for individual factors like muscle mass.
Enter your height and weight, and the calculator returns your BMI value along with which weight category it falls into.
Example: A person who is 1.75 m tall and weighs 85 kg has a BMI of 85 ÷ 1.75² ≈ 27.8, which falls into the "overweight" category.
Is BMI a perfect measure of health? No, BMI doesn't distinguish between muscle and fat mass, so very muscular individuals may be classified as "overweight" despite having low body fat — BMI is a general screening tool, not a complete health assessment.
What should I do if this tool shows I'm overweight? Consider it a starting point for a conversation with a healthcare provider, who can assess your overall health using additional factors beyond BMI alone, like waist circumference, body composition, and lifestyle.
Does BMI apply the same way to everyone? BMI categories were developed primarily from population studies and may not translate precisely to every ethnicity, age group, or body type — some health organizations use adjusted thresholds for certain populations.
What's the difference between overweight and obese? These are different BMI classification tiers — overweight is generally BMI 25-29.9, while obese starts at BMI 30 and above, reflecting increasing associated health risk in population studies.
Can I be "overweight" by BMI but still healthy? Yes, factors like muscle mass, fitness level, and overall lifestyle also significantly affect health outcomes, which is why BMI alone shouldn't be used as the sole indicator of health status.
