Predicting a child's adult height

[popsycal]

I know that this can't be done accurately, but I seem to remember there is a little sum that you can do where you take the parents' heights, do something to them then take child's height at a particular age.....

Anyone know what I am talking about - or do I just sound like Johnny Ball!

BTW - I am not getting out those centile charts.....they have been conveniently lost since I hate them so much.

Anyone?

Hi, Posey! It's OK, I thought it was funny...I wondered how tall you thought it was! 183cm is 6', near enough - 180 would be 5'10-5'11.

It's all tosh though. (I was fairly average until I hit puberty and shot up leaving all the "tall" ones gaping up at me!) If you look at gothicmama's red book example, you're supposed to deduct 7cm from the average of the parents' heights, but it then says the result might be +/- 8.5cm, so what's the point of that???

Not read all the answers so apologies if I repeat.

When you child is 2 they are meant to be exactly half the height they will reach in adult life.

That came from a very intelligent source.

??????????

Only for girls, Thomcat, a boy at 2.5yrs is supposed to be "exactly half" his adult height-- but I don't believe any of it. See my message earlier, by that rule DS is supposed to only reach 5'6", in spite of his 4 nearest male relatives all being near or over the 6' mark! And I'm no shortie at 5'8", too.

Posey: I'm 5'8" or 172 cm ... Plus 8cm must be just over 3" taller, or a nudge over 5'11"?
