BMI is a general screening measure, not a full picture of health. Talk to a doctor for personal advice.
For most adults, a BMI between 18.5 and 24.9 is considered a healthy range, under 18.5 is considered underweight, 25 to 29.9 is considered overweight, and 30 and above is considered obese. These ranges are general guidelines, not a diagnosis.
BMI doesn't distinguish between muscle and fat, so it can overestimate body fat in muscular people and underestimate it in others. It's a useful quick screening tool, but it isn't the full picture of anyone's health.
BMI is your weight in kilograms divided by your height in meters squared. This calculator does that math for you automatically, in either metric or imperial units.
No. BMI is a starting point for a conversation, not a full diagnosis. If you have concerns about your weight or health, it's best to speak with a doctor who can look at the full picture.
It's the weight range that would put you inside the standard healthy BMI range (18.5–24.9) at your exact height. It's a general reference point, not a personal target — healthy weight varies by body type, muscle mass, and other factors this calculator can't see.
