Height Percentile Calculator
Have you recently wondered, how tall am I, or whether your child's development is correct? With this height percentile calculator, you will quickly discover your child's height percentile, as well as what a height chart for boys and girls looks like. And that's not all; in the article below, we will explain the purpose of percentile calculators (including head circumference percentile calculator or weight percentile calculator), how to find percentiles, and, in the end, give you an example of how to use this tool.
✔️ Tip! Some crucial factors in child and teenage growth and development are diet and a good night sleep.
Height percentile assessment  what's the purpose?
A child's development in the first few years of their life is not constant  every kid has periods of excessive growth (making all of their clothes too small before school starts🎓) as well as intervals in which their height remains the same. Therefore, the WHO (World Health Organization) developed growth charts, boys and girlsadjusted. They are based on data collected from thousands of children all over the world, and so are thought to be reliable for the majority of little ones.
Proper height percentile boy, and height percentile girl assessments should be done during every pediatric visit, as following the child's growth meticulously can quickly detect any disorder of development. It's important to know that parent's height, and therefore genetic factors, strongly influence the child's future height (check with our height calculator). Also puberty can come at any time, which means that the kid could have their growth spurt a bit later. That's why a visit to the doctor's and a thorough medical history might help find the answer to any developmental disorders.
Height percentile calculator  instructions of use
There are a couple of steps you should follow to answer the question: "How to find percentile?," or maybe you're curious about "How tall am I, among my peers?". To use this tool, please:

Give us some details:
 age of the child (either in weeks, months or years). Please provide the child's age to an accuracy of 1 week if they are up to 13 weeks old. If they are older, onemonth precision is okay.
 whether it's a boy or a girl (height percentile girl differs from height percentile boy)

The length or height of your child. Remember that you can easily switch between units within the calculator.
After all of that, you will receive some numbers. What are they? The first one is the exact height percentile boy (or girl), and the line below gives the percentile range where the child places (essential for the physician!). In the end, there is a graphic showing where the child places among peers, as well as an interpretation of the growth chart for boys and girls.
How to interpret height chart for boys and girls
After filling in all the fields in the height percentile calculator, you'll see some figures. As you've seen in the previous part, the first number is the exact height percentile girl (or boy) result. Below there is the range in which that percentile lies, e.g., between the 15th and 50th percentiles. This would mean that 50% of children are taller than the kid, while 15% are shorter. The 50th percentile is the middle, and therefore it shows the average height for a child of that age.
A height percentile that is either below the 3rd or above the 97th percentile should be concerning. In the first case, it might mean that your kid is too short for their age, while the latter means they are too tall. Although your kid might become a natural basketball player, we recommend that in such a situation, you consult a physician and a dietitian. Also, it may be wise to also check their weight percentile, to see whether they follow the same ranges in both classifications.
Height percentile boy/height percentile girl  important facts
Doctors consider the rate of growth as an important factor when looking at the height chart for boys and girls:
 The child should follow the same percentile line on the chart as they grow.
 If the results cross two or more percentile lines (they raise/decrease by at least two ranges), e.g., from the 75th85th percentile to the 15th25th percentile, you should consult a doctor.
 If their height is below the 3rd or above the 97th percentile, check if the baby has always been in those ranges. If your child has only entered these ranges recently, consult a doctor. Also, take a look at their weight and BMI calculator for kids.
Our data derives from the WHO (World Health Organization), and the standards that were developed using data collected in the WHO Multicentre Growth Reference Study. The data only covers children aged up to 19, which is why this height percentile calculator can't be used for anyone older.
How to find percentile in practice
Let's put theory into practice and work on an example. Anthony is a 45 years old father of an only child. The child has recently turned fourteen but seems a little bit small for his age. He hasn't had to change his desk height for far too long. Therefore Dad started wondering what should be the average height for a 14yearold boy and took him to a pediatrician.
The physician calculated his percentiles with this height percentile calculator: age: 14 years, sex: boy, height: 146 cm
.
The results were: exact percentile: 2.53, between 1st and 3rd percentile
. Even though according to the BMI calculator for teens, the parameters are correct, the height classification means that he is of small stature, and his development requires further diagnostics.
We try our best to make our Omni Calculators as precise and reliable as possible. However, this tool can never replace a professional doctor's assessment. If any health condition bothers you, consult a physician.
