What formula can estimate offsprings heights most forseeably?
« on: November 30, 2020, 12:20:46 PM »

Ive known of a formula:Your height=(Fathers height+Mothers height)/2士7.5cm
I dunno if thats the most reasonable one although I think it is.

None.

With the above formula I should have been 1,73 but I was 1.685 prell.
Definitely there isn't any formula to predict height.

For whatever formula there is, the output should vary by sex rather than be a range around a single mean, since it's a bimodal distribution. Also, the variance would probably be very high, unless you take into account the heights of both sets of grandparents as an input as well.

Actually I just wanna assure if I screwed up my genes.
I was below 140cm tall when I was 12 y.o and now I'm 162-163cm tall now(20 y.o).

This formula works. But you have to keep in mind that from the number you get, there is a 95% chance you will be within 4 inches away from this height (either up or down). So it gives you a confidence interval, it does not give you a certain height.

There are more accurate formulas, but the baby needs to be born already

4 inches of height are way too much for a formula to be considered accurate for height.
It is common sense that a 5.5 man and a 5.3 woman won't make an 6.4 ft son most of the times.
A working formula should be accurate at least 1 inch more or less not 4 inches!

Because height ain't decided by just one factor(Although gene is the most important factor) and even speaking of genes alone offsprings may realize mutations.That is to say if you are in the twenty-distance range of the result your height is generally reasonable.

Ofc that would be ideal, but afaik there is currently no such formula

Now if the baby is already 2 years old and you know bone mass and stuff, there are more accurate formulas I think

You’re right, but according to the aforementioned formula, there’s only a 5 percent change of ending up > 2 inches shorter/taller than your predicted height.

So if your predicted height is 5’5, there is a 95 percent chance that your actual height will be between 5’3 and 5’7.

If you got that right my predicted height is only f||king 160cm and I'm 162cm tall.

Your point being? According to the formula, if your predicted height is 160 cm, there is a 95 percent chance that your actual height will be between 155 and 165 cm.

Then my point is to highly admire this mysterious formula cuz it precisely predicted my inherited height.

OK, I googled again and am no longer sure if what I wrote earlier is correct. Some sources say it’s +/- 2 inches, and some sources say it’s +/- 4 inches.

I think it is 4 inches either up or down

I found this in a book about parenting (for dads):

Using the mid-parental height method, you first average your height with mom’s height. If you are six feet tall and mom is five feet tall, the average of your heights would be five feet six inches. Next, you add two and one-half inches to this average if you have a boy, or subtract two and one-half inches if you have a girl.
Using this example, you would then expect a boy to be five feet eight and one-half inches and a girl to be five feet three and one-half inches tall. Of course, this is just an estimate and not some magical formula. Your child may be a little taller or shorter than that, although there is a 68 percent chance that a child would be within two inches of that prediction.


I assume that if your parents grew up in a developed country, chances are you’re part of the 68 percent whose actual height is within two inches of the predicted height.

What would be more interesting to find out rather than these formulas if whether it is the father's height specifically that decides the height of the children (especially son) or both parents. I have found divided opinions on this. If it is the former case, then it is over basically. If it is the latter, then screw formulas, just marry as tall a woman as possible.

Of course it’s not only the father’s height that determines the child’s height (just look at Jaden Smith, for example).

There isn't a 100% accurate formula, but we can generally predict height with the formula that you provided.

https://www.scientificamerican.com/article/how-much-of-human-height/

But obviously, height isn't all genetics. They say 60 to 80 percent of the difference in height between individuals is determined by genetic factors, whereas 20 to 40 percent can be attributed to environmental effects, mainly nutrition. There is also luck involved since there can be a mutation or injury. Heck, you can even get a benign tumor on the pituitary gland and become a giant. But most of the time, your formula will be accurate for most people.

A couple of anecdotal evidence doesn't disprove scientific data.

Of course it only says "suggests" but not off to a good start

Do you have a link to that study?

Just some more anecdotal evidence, my wife is about 30 cm shorter than her dad and 5 cm shorter than her mom. Why? Probably because her grandma is really short. So even grandparents can influence a child’s height.

And some more: https://www.celebheights.com/a/60.html

Again, I highly doubt that it’s only the father’s height that determines a child’s height.

I don't know which study it is sorry. And this is the only article I have ever seen this being mentioned so it might not hold too much value.

But it is something worth bearing in mind. Although considering how complex height genetics are, perhaps indeed it would make sense to assume that both parents contribure their fair share. I am biologically illiterate though so take my word with a good grain of salt.
