If you are a 5ft 3in tall 11 year old and your mother is 5ft 6in and your father is 5ft 5in how tall will you probably be as an adult?

While parental height can be considered a marker for how tall a child will grow on average, it is by no means a dependable guide. There are many numerous examples of children who grow to tower over their parents, just as there are some that don't. The height you gain from this point on will be determined by a host of variables, including how old you were when you entered puberty, what stage you are at now, how quickly you are growing, and when the growth plates on your bones close (a sign of the completion of puberty). Genetic influences are also an unfathomable variable that make forecasting a child's eventual height very difficult to predict. There are very few things a person can do to influence his or her final height. It should be noted that children who enter puberty a little later than their peers, tend on the average, to be taller.
