BMI Calculator

Please enter a valid height and weight to calculate your BMI.

BMI is a general screening tool and doesn't account for muscle mass, age, or body composition. Not medical advice — speak with a healthcare professional for personalised guidance.

What Do BMI Categories Mean?

Under Below 18.5

May mean insufficient energy intake. Worth discussing with a doctor if unintentional.

Healthy 18.5 – 24.9

Linked to the lowest risk of weight-related health issues for most adults.

Over 25.0 – 29.9

Some added risk of type 2 diabetes and heart disease. Small changes help.

Obese 30.0+

Linked to higher health risks. A healthcare professional can help build a plan.

Note: thresholds are the same for adult men and women, but BMI doesn't distinguish muscle from fat — very muscular people may show a higher BMI without excess body fat.
