## How tall will I be?

## Height Calculator

Below the height prediction is some other interesting predictions relating to percentiles, weight lifting ability, and speed.

The following additional analysis is for characteristics of an adult of the predicted height and weight above. Please note that the results are predictions for a statistical average and do not apply to anyone in particular. All predictions are relative to a person of average height and weight unless indicated otherwise by a *. For more information, click on the various section titles.

## Height Calculation Methods

### Mid Parental Height Calculation

The simplest height calculator draws on the fact that children inherit genes from both parents. It takes the average height of the parents and add 2.5 inches (6.5cm) for boys or subtract 2.5 inches for girls. But if the child’s height trajectory points to a greater height, don’t go hunting down the mailman just yet; with so many genes involved, some of which may be recessive, and the possibility of environmental influences, child height can differ considerably from parental height.

### Calculate by Doubling Height at Age Two

Another popular approach to predicting adult height is to double a boy’s height at age 2 or a girl’s height at age 18 months. While this approach does incorporate the child’s own height, and thus their own genetics, it is over simplified and unlikely to provide an accurate prediction.

### Khamis-Roche Height Calculation

The Khamis-Roche Method^{1} combines the best of both of the above methods by looking at both parental height and the child’s height at the current age. Furthermore, it incorporates weight as this too is telling of growth to come. This is the method used by the height calculator at the beginning of this article.

### Bone Age Height Calculators

More advanced height calculators make use of bone age, which is a measure of age based on the size and shape of the bones as seen in radiographs, and formulas such as those found in the Tanner-Whitehouse method. Bone age isn’t always available, and it was actually for this reason that the Khamis-Roche method was developed.

### Calculate Height From Height Percentile

Another method is to calculate height percentile and then check that same height percentile for adults. Similarly, there are also growth charts for analyzing height, but that’s a topic for another article.

### Height Calculation Methods Summary

While a height calculator may be useful, it is not intended for cases where an underlying height related disorder or syndrome may be present. Additionally, these methods have generally been developed for white American children and thus some prediction accuracy may be lost for other populations. In actuality, a pediatrician or endocrinologist is the best resource when it comes to understanding a child’s height. For further reading, you might check out some of the books below.

## How Tall will I be at a Certain Age?

One way to get an estimate of how tall you will be at a certain age is to use growth charts. Note though that growth happens irregularly, and so predictions can be off. The calculated height at various ages in the results section is based off of CDC growth charts. It is just adjusted to the height prediction method selected.

According to this, my almost 7-year old grand daughter will be 6’4″

These calculators are just approximate, plus or minus a few inches, but either way sounds like she will be very tall!

i put in my saved stats from when i was 14, and it hit the mark straight on, so yeah its an approximate, but im my case a pretty damn good one

Nice. My height while I was growing up was marked on a doorway but then it got painted over. Still have a picture, but that might be a bit tricky to extrapolate!

i have a few stages of growing up where my height got inprinted on my brain, at 13 when i got a new passport photo. and at 14 when i had my confirmation. but i only remember the height, the weight i had to estimate

I remember a somewhat similar experience…

Mine was off by 4 inches. I grew until I was 20 though so that might be a factor.

According to that, I should be 9 inches shorter

Did you use the second calculator? That one tends to be a lot less accurate…

Yep, I’d have to ask my parents for how tall I was at a younger age for the first one, not feasible at this hour

The second one isn’t influenced by which genes where actually inherited nor their expression nor environmental factors thus far in a child’s life, so it can be way off. It was way off for me too.

Hmm, the one with the child’s known height and weight predicted me at 6’11”. The one with mom and dads height alone said I would be 5’9″. I’m 6’4″, and I call BS on this calculator…

No surprise the second one was off. But for the Khamis-Roche Method… what values did you put in?

The first one said I would be 5’11”, which is not happening, and the second one said I would be 5’8″. I’m 5’6″

What info did you enter?

According to this my son will be 6’9

My parents were not very tall, my father was 6′ and my mom is 5’7 but all my uncles on my father’s side and their children, including girls were very tall. My father’s oldest brother was 2 meters.

Not very tall? Well my mom is 5’2″ and my dad is 5’10″… if you call that not very tall my parents must be miniscule

Your mom is kinda small, but your dad is pretty much average, this post my interest you: http://tall.life/definining-tall-how-tall-is-ta/

Your parents are pretty tall

Useless, put my own details in aged 9. Apparently I would be 6’9″! I ended up 6’4″.

You are certain you have both your height and weight from when you were 9 accurate?

I am 15 and I am 181 cm it said that I will be 188.3

Which calculator did you use? What numbers did you enter?

Hii excellent website.

One Question

How you set properly featured page images in home page? I am using this template but the feature page images cropping not set properly

I’ve heard that can be an issue. I would upgrade to a different slider if you are having problems. I will be using Master Slider at some point probably.

i got a shorter height than what i already am?

What numbers did you enter?

It says she’s gonna be 6ft 9 inches she 5ft 6 an 11 now

if my mum is 6 2 my dad is 5 10 and I am 13 at 6 1 will I be tall

What does the calculator say?

My dad is 6 foot 3 and my mom is 5 foot 3 i am 12 years old and im 5 foot 6. And the second calculator says i will be 6 foot 4 should i believe itÂ¿

My mom is 5’3″ and my dad is 5’7″ and it said I’m gonna be 6’1″ I’m a male so it makes more sense

My parents are around the same height I got 6″2

according to this my height will be 6.8.2

wait, so according to the first one, I should be about 5.9 and the second one says I’ll only be about 5.5…which one do you think is more accurate? I mean i could just be fat and thats why its tall but IDK

The second one tends to be more accurate. One might also check their current height percentile and then see how tall an adult of the same height percentile is. You can do that here: https://tall.life/height-percentile-calculator-age-country/

according to this calculator i should be 5’9 (1st) one

and 5’8.5 (2nd) one. im currently 13 weigh 102 (approx) and am 4’11-5’0 hope i grow all other classmates are tall!

I am 11 and 5 6 I am so tall ?

I’m 13 and 6 foot 2

im 12 and 5 foot 5

I’m 13 and 3’3 1/2

yall tall af im 16 4’10

13 in a month and 5’9″ bro

Im supposed to be 184 and im 14,5 right now. Is it possible to become any taller than that?

Hey look, I’m going to be 6’1″ That’s awesome!

The first one said I will be 172.9 cm and the second one said I will be 161.1 cm so I don’t know which one to believe. It said the first one was more accurate, which I believe to be more logical as it has you put in your age and your current height.

First one is more accurate. You might check your height percentile as well: https://tall.life/height-percentile-calculator-age-country/

I’m confused as I’m 18 and I’m only 5 foot 7 and I’m meant to 5 foot 11.5 inches, Can you tell me whats going on?

Which calculator and what numbers did you enter, exactly?

I used the father and mother height on tall.life

Hey buddy im currently 14.3 years old i put in 14.5 years old and 35 lbs i ak 5″4 so i put that in and my mom is 5″4 as well i put that in my dad is 5″7 i put that in im a male then i calculated it sayd 5″9 i will be glad i will get 5″9 but is it true???

Predicted adult height: 336cm

I said my mum was 164cm and my dad 172cm

Did they really just add their heights together?

Okay then..

When I put 164 and 172 into the second calculator, I get 174.4 cm… maybe try again?

I’m 11 and 5 2 and it said I’m opposed to be 6-foot 3.9 inches tall

My predicted height is 6’3.5″, I really hope this happens. I just turned 14 and I’m 5’7″, I just started my growth spurt

Right now I am 5″4′ and this says I will be 8″4.8′

I don’t mind being 6 foot something but 8 foot something is to much

i hope this things wrong cause i want to be at least 6ft

According to this my twin daughters will be 6ft 7inces?!? They are tall but 6ft 7 that is an extreme

i am 14 and 6’2 and it says i will be 6’5. is this really accurate?

the first one says ill be 189.9(6.2-3) while the second one says ill be 181(5.11),by the way am 13.7 and 5.7

my mother is 5.6 and father 5.11-6 ft. which one do u think is more reliable

Given one has all the right numbers entered, the first height calculator will be more accurate.

According to the first calculator, it said that I will be about 6.2 to 6.3 . I am currently 13 and 5.7 and 64 kg. Is this accurate or not?

I’m 12 and I’m 152 cm’I used the first one and I got 177.8 cm,but my parents are really short.My mom is 153 cm and my dad is 165 cm.

You probably will be short

Hi my names is Zachary I’m only 5″3 and I’m only 16 years old I was wondering is there any chance that I will continue growing

The first calculator said i will be 6’2″ while the second said i will be 5’7.5″!But for the present i have already crossed 5’7.5″.I am somewhere between 5’8″ and 5’9″

Does this actually work? I’m pretty scared about how tall I will be?

My future height is 177cm based on this, but how would I know this is true?

This thing says I’ll be 5’11.5 but I’m hoping it’s wrong cuz I kinda wanna be at least 6’1

I’m gonna be 6″7′. Awesome!

Yeah, IDK if its right but it said I’d be 6’8 which seems accurate to me as I am 6’2 at 14

so my mom is 163cm(5foot 4) and father 174.5( 5 foot 9 basically) and im 176 at age 15.5 and weight like 170 pounds so what height can i reach like do i have a good chance to reach 183cm(6foot tall) the only thing that i havent got yet from puberty is a deep voice and chest hair and i still dont shave cause i dont have a beard and my face looks like im 13-14 do i have a good chance at reaching 6 foot tall

I’m 15 and i’m 5’8 but my mom is 5’4 and my dad is 6’2 and the thing said I’ll be 5’10 and the second one said 5’6

I just did this for both my kids. I used their height when they where 4. My son is almost 19 and he is 6’6 which is exactly the height predicted. When I put in my daughter who is 13, I entered her height at 4 and currently. It gave me 6’1 which is the same height we have been told by doctors. She is currently 5’71/2. I wish I had my information from when I was a kid so I could see if my results are accurate.

Wow! I know that I might be a little bit shorter or taller, but it said when I’m a adult I would be 5’10.6! I was always told that I would be short because my parents are, so this made my day!

I have a question, I used the top calculator and got 5’11.6 but then o used the bottom one and I got 5’3, and I’m already 5’2 and only just a pre teen, so which calculator should I trust more?

The top calculator tends to be more accurate, but it to is subject too is just an approximation.

I am 14 years old and im 180 cm tall this calculator says that I will be 193.I hope so ot would be like that cuz im into basketball

D 1st one says ill be 5’10!!

I’m 12 and one month old and I’m 5’2 and I’m suppose to be 5’10.32

Im 14 and 5’10 this said im supposed to be 5’10 so ig im gonna stop growing.

I put in my details on every i coukd find height calculator and apparently I will be 6’1 to 6’4.

Really Good. I’m 11 3 months and i’m 152.6. It predicted 189.2
