Have you ever wondered how tall will i be or how tall your little one will be? Here’s your (best guess) answer! Use the child height predictor tool below to come out with a predicted height!
Factors that Determine Height
There are a number of factors that can determine the height of your child. Below are many of them, followed by a fun video describing many of the factors.
1.Genes
Scientific American says that about “60 to 80 percent of the difference in height between individuals is determined by genetic factors.” The reality is that the height of a person’s natural parents has a huge impact on the height of the child. So if you are ever wondering “How Tall Will I be?”…. look to your parents’ height as a major determining factor. However, this still leaves 20-40% of the factors determining height as environmental.
2. Gender
Males tend to be slightly taller than females on average, due to females having two X chromosomes and boys entering puberty later than girls.
3. Health Affects
Healthy individuals tend to also grow taller. In addition, many specific medical conditions do inhibit growth in a child.
4. Exercise
Physical activity can aid in the growth and health of a child.
5. Nutrition
Nutrition is one of the biggest non-genetic factors in height development. Focusing on children’s nutrition is something that will pay off, not only for height, but for overall health.
6. Posture
Not only can good posture itself literally add height, but in children can affect growth by placing only the necessary and proper tension and force on one’s discs.
7. Stress
High levels of stress in children has been associated with slowdowns in growth.
8. Other
There are other possible growth determining factors, such as getting good sleep, hormone levels, and many have to do with the 7 categories above. You may want to check out this cool Neuman & Neuman video on what determines height for a better understanding:
The tool above typically yields an answer within a 3 inch variation, which can either be significant or insignifcant depending on the purposes.

I am excited to begin contributing to The Inspired Home! Holly and company have done an amazing job getting the site off the ground and I hope to continue in their path. I am a father of 2 little ones who never fail to keep me busy, and live in a Chicago neighborhood.
It’s a nice calculator! Having meters might be useful, but otherwise I like the design. I prefer, however, Parley’s method which requires you to have very little information – age, sex, and current height. It’s also nice for children who don’t know their biological parents because obviously the height of their adoptive parents wouldn’t be useful.
That website is completely incorrect
I’m 12 female 5’5 it says that i’ll be 5’5 at adult age (my mom’s 5’4 and my dad’s 5’7)
You probably will be, ngl.
it doesn’t work i was 156cm when i was twelve my mom is 163cm and my dad is 180cm and it said i will be 172cm but now i’m 189cm so it’s really just confusing
You may have put female
I am a kid who is 4’4″ inches tall and I am 8 years old. I found out that I am going to be 5’11” inches tall when I will be 18. I want to be taller, but at the same time I want to be more than 6 feet taller.
You’ve got good grammar for someone who is 8 years old, but how tall you’ll end up may be more or less depending on your health and other factors; but it’s 80% genetics.
Im currently 5’11 but it says I’ll be 5’5 at 18, am I going to shrink or is the calculator wrong? (I’m a guy, my mom is 5’6 and my dad is 6’8)
NO , you will not shrink, most likely you’ll grow to 6’5-6’9.
Hi I’m 5’11” tall I’m still growing my father is 6’1” tall and my mother is 5’6” tall
You will most likely end up 6-4 to 6-7 because was your heght at 11 and my parents are same height as yours and I am now 16 and 6-6
Hey 15 and currently 5’6 still growing.
My dad is 5’8 and my mom is 5’5 and it says I’ll be 5’10 at 18. I could potentially see taller in the next few years seeing if I’m getting my height from my mom’s side of the family with some huge guys.
But would 5’6 be considerably good for a guy like me?
yep the calculator is broken
