![]() ![]() The closer you get to 1, the healthier your BMI is said to be. To obtain your BMI prime, all you need to do is to divide your actual BMI by 25, and you will hopefully obtain a number close to 1. Still, we have decided to keep it here for a comparison between calculators and also for consistency. Although this is very useful for men and women, its validity is questionable at best for teens and kids. The standard value for a healthy BMI in adults is 25kg/m². This quantity, derived from BMI, measures how close your BMI is to the "healthy BMI for adults". ![]() There is one more item in the BMI calculator for teens that we haven't mentioned yet, BMI prime. However, for teens and kids that are still developing, there are only 4 categories recognized by WHO: Underweight (lower than 5th), Normal/Healthy (5th-85th), Overweight (85th-95th), and Obese (higher than 95th). For the adult population, each of these groups represents a different BMI category. Since making a distinction between the 72nd and the 73rd percentile is effectively irrelevant, percentiles are typically grouped according to the BMI categories they represent.įor example, in this calculator, we follow the WHO (World Health Organization) ruling and group the percentiles of BMI for teens in 10 groups: lower than 5th, 5th-10th, 10th-25th, 25th-50th, 50th-75th, 75th-85th, 85th-90th, 90-95th, higher than 95th. So if your BMI is in the 30th percentile, that means that your BMI is higher than 30% of the population. The percentile is the position you occupy in the BMI range in comparison with the rest of your population. For easy comparison, BMI is typically divided into percentiles or percentile groups. This is not to say that BMI is useless since most of the population is 'averagely healthy', but just that it needs to be taken with a pinch of salt. BMI ranges and BMI charts are constructed using data from people's actual body mass indexes, so this can skew the results. These shortcomings of BMI are due to its statistical nature. The second thing to note is that BMI doesn't consider body types and body shapes, so if you have an uncommon or extreme body type, your BMI might not be a good indicator of your health. This means that athletes and very active people might have "unhealthy" BMI values despite being totally healthy. The first thing to know is that BMI is meant as a measurement for sedentary people. We have talked in great detail about the flaws of a statistical tool for assessing the health of one individual in the general BMI calculator, but as long as we set some constraints, BMI can still be useful. In fact, BMI was always designed to be a statistical comparison tool to assess the state of a person's body. It is useless to talk about BMI without a point of reference or comparison. Having multiple calculators allows you to get more precise information regarding the population group, presented in an orderly manner. We will get into more detail about these topics in a later section but for now we can say that different populations have different acceptable values for BMI for example, the value for a healthy BMI for teens is not the same as that for a 2-year-old child. The answer is very simple: statistics and percentiles. Some of you might be wondering why we made so many calculators if the BMI formula is the same no matter the person. If you are feeling curious we encourage you to check out all of the calculators, since there is interesting information not only about BMI, but about its relation to health and how to properly use this value to your advantage. BMI calculator for kids (boys and girls up to 10 years old).Feel free to use the one that best suits your needs by following the links below: In fact, we at Omni have created a total of 5 BMI calculators that include a general BMI calculator (jack of all trades, master of none) as well as specific BMI calculators for men, women, kids, and teens. ![]()
