AD ยท 90

BMI (Body Mass Index) is a simple measurement used to assess whether your weight is in a healthy range for your height. While BMI is not a perfect measure of health โ€” it doesn't account for muscle mass, age, or fat distribution โ€” it's a useful starting point recognized by Health Canada and the WHO. Our calculator supports both metric (kg/cm) and imperial (lbs/inches) units.

How It Works

1
Choose your unit system
Select metric (kilograms and centimetres) or imperial (pounds and inches/feet). Canadian standards use metric, but both are supported.
2
Enter your weight and height
Use your morning weight without clothing and stand straight without shoes for the most consistent measurements.
3
Read your BMI category
Your result places you in one of six categories from Underweight to Obese Class III, with your healthy weight range shown.

Tips & Best Practices

โœ“BMI is a screening tool, not a diagnosis. A high BMI warrants assessment by a healthcare professional.
โœ“Athletes often have a high BMI due to muscle mass โ€” BMI doesn't distinguish muscle from fat.
โœ“Children and teens use different BMI charts based on age and sex โ€” adult charts don't apply.
โœ“Waist circumference is an additional measure: over 88cm for women or 102cm for men indicates increased risk.
