BMI Calculator
Estimate body mass index from weight and height, a quick screening number, not a full health picture.
Formula
BMI equals weight in kilograms divided by height in metres squared.
How it works
Enter your weight and height, and the page divides weight by height squared. The result is shown with a broad weight-status band. Muscle, bone and body shape are not captured, so treat it as one screening figure alongside other measures.
FAQs
Is this result exact?
No. It is a population screening formula, so two people with the same BMI can have very different body composition.
What affects the result most?
Weight and height. Small height errors change the result more than most people expect.
How should I use this result?
As a starting point for a conversation, not as a diagnosis on its own.
