Visual BMI Calculator

A Clearer Way to Read Your BMI

The Visual BMI Calculator turns the usual body mass index number into an easy-to-read coloured chart. Enter your height in centimetres and weight in kilograms, and the tool plots your result on a gradient scale that runs from underweight through the normal range to overweight and obese. A pointer marks exactly where you sit, so you can see your category at a glance instead of comparing raw numbers.

BMI is calculated as weight in kilograms divided by height in metres squared. It is a quick screening measure for adults and a useful starting point for tracking changes over time.

How to Use the Results

Because the chart is visual, it is helpful for setting goals and watching gradual progress as your weight changes. Remember that BMI does not account for muscle mass, bone density, or where fat is distributed, so athletes and very muscular people may read higher than expected.

Treat your result as a general guide, not a diagnosis. For a full assessment of your health, including waist measurement and other factors, speak with a doctor or registered dietitian. The calculator runs entirely in your browser and does not store the figures you enter.
