BMI Chart for Adults (Men & Women)īMI Chart for Kids & Teens (Girls) 1.5 History You can use them to easily locate your height and weight to determine your BMI score and the associated BMI category you fit within. Here is what that reading looks like when based on BMI percentiles.īody Mass Index charts are useful for visualising the ranges associated with each BMI category. This BMI figure indicates that he is at a healthy weight because the proper range is between 90 and 128 pounds in this instance. At the 95th percentile, your child is classified as ‘overweight’.Įxample: If your child is a 14-year-old boy who is 5ft 3 inches tall and weighs 120 pounds for example, his BMI is 21.3 which puts him in the 76th percentile. The 85th percentile means that 85% of kids have the same or lower BMI and this is a figure where your child is classified as being ‘at risk’ of becoming overweight. This calculation results in a body mass index percentile.įor instance, if your child is in the 50th percentile, it means that 50% of children of the same age have the same BMI figure or less. As a result, BMI is a measure of weight for height compared to children of the same age. While the BMI ranges remain the same for adults throughout their life, these figures change in children because kids are still growing and do so at different rates. The following body mass index chart allows you to manually get your BMI score and includes a classification of the BMI category you reside within.Īlthough the BMI calculator works in the same way for children, the measurement is used differently. The table below lists the BMI categories along with the BMI score associated with each category. Technically, the BMI scale will place you in one of six categories. 26.784 becomes 26.78 and so on.īut where does this place you on the BMI category chart? In the next section we cover the bmi categories and explain the classifications. Why the difference? Because there is a certain element of ‘rounding up’ or ‘rounding down’ involved e.g. Using the same example as before, you calculate as follows: Weight in pounds / your height in inches squared x 703 Example BMI CalculationsĮxample 2: Some countries use an entirely different calculation to reach the same result. If you are 5ft 4 inches by the imperial system, you are 162.56cm or 1.63m (rounded up) by the metric system. If you wish to calculate your BMI using the imperial system, here’s the height and weight conversion figures: The metric BMI formula = Weight (KG) ÷ Height (Metres²).The imperial BMI formula = Weight (LBS) x 703 ÷ Height (Inches²).It’s a simple calculation that takes into account your weight and height. The body mass index formula is easy to determine. The result is used to determine if that individual is obese, overweight, normal weight or underweight depending on where they fall within the BMI category ranges. It is also determined via a BMI chart table and is an attempt to quantify the level of tissue mass (comprised of bone, fat, and muscle) in a person. The body mass index, occasionally called the Quetelet index, is a value taken from a person’s height and weight. Even with the advances in medical technology, the Body Mass Index (BMI) is one of the most frequently used measurements of a person’s physical shape and general health, some 150 years after it was first conceived. There are numerous tools used to calculate whether or not a person is overweight. In other words, aesthetics doesn’t enter the equation carrying too much weight is bad for your health. The terms ‘overweight’ and ‘obese’ are defined as “abnormal or excessive fat accumulation that may impair health” by the WHO. There are now 1.9 billion overweight adults around the world, 650 million of whom are obese. The WHO published an updated list of statistics in February 2018 and found that global obesity has tripled since 1975. The most recent obesity statistics from the World Health Organization (WHO) make grim reading. Body Mass Index (BMI) – The Complete Guide
