Why should my weight affect the height I'm going to be?

Question

http://www.webmd.com/content/tools/1/calc_kid_height.htm

When I tell it I weigh ___ (not putting it here!) it tells me I'm going to be 5'4. When I take 7 pounds off that, it says I'm going to be 5'5. I don't get that. It doesn't even change when add an inch to what my current height is, but it changed when I took off 7 pounds.

If I were to actually lose 7 pounds, would I grow to 5'5 or is this predictor wrong?

Answer 1

usually - if your parent(s) recorded your height at 39 months
you double that and it gives you a rough estimate
of your future height

however, I started drinking tea at age 12 - -
and I think I could have gone to 6-4 instead of 6-2

nope - don't know that weight holds you down
and great things come in small packages - you will be fine!!

all the best
