BMI Calculator

If your BMI is between 18.5-24.9 then your weight falls within the normal range. The World Health Organisation reckons that adults should stick within this range and avoid weight gain of more than 5 kg (11 lb). If your BMI is below 18.5 you’re classed as underweight, a BMI of over 25 makes you overweight and a BMI of over 30 makes you officially obese

Be warned: the BMI calculation isn’t particularly accurate for determining whether children and teenagers are overweight or obese.
