Find out your BMI category and how much weight you would need to lose to reach the normal BMI range.
This tool checks your BMI category and estimates how much weight you would need to lose to fall within the normal BMI range.
BMI is calculated as weight in kilograms divided by height in meters squared. The normal range is defined as a BMI between 18.5 and 24.9.
Enter your height and current weight, then click Calculate to see your BMI category and how much weight change would bring you to the normal range.
Example: A person who is 170cm tall and weighs 85kg has a BMI of about 29.4, in the overweight range, and would need to lose roughly 13kg to reach the top of the normal range.
Is BMI the only measure that matters. No, BMI does not account for muscle mass, so athletes may show a high BMI without excess fat. Consider body fat percentage too.
Should I try to lose weight quickly. Gradual, sustainable weight loss of 0.5 to 1kg per week is generally recommended over rapid loss.
