Most people know that their weight has a strong effect on their health. But not everyone has a clear picture of what is an appropriate weight for them. Being overweight can increase your risk of a number of illnesses, including coronary artery disease, high blood pressure, diabetes, and stroke. But there are also hazards involved in being underweight, including nutritional deficiency diseases, and obsession with weight loss can lead to eating disorders, which can be very harmful and even fatal.

Your best weight range is calculated on the basis of your height and weight, producing your body mass index (BMI). A healthy BMI is between 18.5 and 24.9. Find out what yours is - enter your height and weight into the boxes below (in metric or imperial) and press Calculate.

Although the BMI is useful for healthy adults (ages 20 to 65 years), it does not apply to infants, children, adolescents, pregnant or breastfeeding women, endurance athletes, highly muscular people, or adults over 65 years of age.
