Body Mass Index Children US

BMI children USThis module calculates Body Mass Index for children from age 2 to age 18 and classifies the result according to the guidelines given by the U.S. Department of Health & Human Services. It also has an optional evaluation of height in relation to age.

Instructions:
1. Enter values for gender, height and weight.
2. The result is interpreted within four categories: Underweight (<5th percentile), Healthy weight (5th-85th percentile), Overweight (85th-95th percentile) and Obese (>95th percentile).
3. Please note, that BMI is only a very rough predictor for overweight in individuals.

Background

For adults, the body mass index limits for overweight and obesity are straight forward (overweight = BMI > 25 and obesity = BMI > 30). For children this is much more complicated as the limits vary a lot depending on age. This calculator uses the US guidelines that are based on fixed percentiles from a large reference population. 

A BMI of 20 indicates obesity in a 6 year old girl, whereas it would represent healthy weight for a 13 year old girl. However, as growth of children varies, the final evaluation should always be based on a several factors including physical growth, muscularity and subcutaneous fat deposits.

The calculator also includes the possibility to evaluate height in relation to age. If the child/youth scores in the high percentile range on height (above average) this could indicate that physical development is ahead of chronological age. As higher BMI is expected with increasing age (above age 6), this information can assist in a qualified evaluation of BMI.

Hi, I’m 12 going on 13 in June. I’m 5”1 and I weigh 109.5 lbs. is this overweight? I have a lot of leg muscle because of soccer and I don’t think I look thick around the waist, I only have a 23 or 24” waist. I am just very self conscious about my weight.

Hello,
The world wouldn’t be so interesting if we all looked the same. What makes us unique in a way, different, pretty or handsome in a good way is that we look different. Imagine everybody with the same hair ,skin Color and eye colour as you. I know I share would like it. Some of us may feel we can’t tell an adult that they may lecture us. It is a good idea if you pick someone you can trust and tell them your thoughts. What I am trying to get at is it’s ok to be different whilst being healthy, not to big but to small.

Yeah but no one wants to be fat.

I was in the same boat as you about six months ago. I had no idea what to believe online because everything seemed to be an advertisement. I actually read a personal review about "Lean Belly Breakthrough" and it seemed like the person had great success using the product so I gave it a try. I couldn't have been more excited about the results, as I am now 50 pounds lighter than when I first started using it. The article was very helpful to me -- if you want to check it out yourself you can read it here: https://www.howtogetapp.com/2021/02/weightlossdiet.html

Hey there I was just wondering if I am 12, 5'3, and 125 pounds, am I overweight? I would guess that I am probably I little over the limit for not being overweight, but you should know that I am pretty athletic and you could say I have some muscles and such. So let me know I guess, thanks!

Hello, I'm a 12 year old female. I just want to know if it's overweight to be 129 pounds. I don't really feel ok saying this, but I just want to know, this whole COVID thing had me gain weight. I love to be who I am but sometimes it's ok to take care of yourself.

I don't think so but I'd like to know as well. I'm also 12 1/2 (female) 5'5" and 130 pounds.
Also I'm 5ft 4 in a half

I think it really depends on your height and where you originated from. But if you are 5’5 and 130 lbs, pretty sure you are fine but check with your doctor or local clinic just in case. I’m not a professional, and this site is just an estimate, it doesn’t really tell you if you need to gain or loose weight.

Hi, I’m 12, turning 13 on April 2nd. Im pretty sure I’m 4’10-5’1,I haven’t checked since August in my local doctors office because of the pandemic. I weigh 85.4 lbs. I’m going to be honest on that I don’t do much exercise, little to none, and have no upper or lower body strength. I have been gaining weight very excessively these past months and I have no idea why. Am I gaining weight?
