Calculate your Body Mass Index (BMI) instantly. Enter your height and weight to find out your BMI category.
About this tool
Body mass index, or BMI, is a simple screening number that relates your weight to your height. Health professionals and public health guidelines still use it as a starting point when asking whether someone might be underweight, in a normal range, overweight, or in a higher-risk band—though it is not a diagnosis on its own. This BMI calculator supports both metric (kilograms and centimetres) and imperial (pounds and inches) so you can work in the units you already know. You will see your BMI value, the usual category labels, and short context that matches what people expect from a body mass index search. Athletes and very muscular people may read “overweight” even when body fat is low, so consider BMI alongside other signals if you are making health decisions, and talk to a clinician for personal advice. The interface stays minimal: type your numbers, get a clear result, and move on. Keywords like BMI calculator, healthy weight, and am I overweight are all pointing at the same idea—one number, clearly explained, without a wall of medical jargon.
Frequently Asked Questions
What is a healthy BMI?
A BMI between 18.5 and 24.9 is considered healthy for most adults. Below 18.5 is underweight, 25–29.9 is overweight, and 30+ is considered obese.
Is BMI accurate for everyone?
BMI is a general screening tool and may not accurately reflect body composition for athletes, elderly people, or those with high muscle mass. Always consult a doctor for a full health assessment.
How do I calculate BMI manually?
BMI = weight (kg) ÷ height (m)². For example, if you weigh 70 kg and are 1.75 m tall: BMI = 70 ÷ (1.75 × 1.75) = 22.9.
