Summary: For most people, height will not increase after age 18 to 20 due to the closure of the growth plates in bones. Compression and decompression of the discs in your spine lead to small changes in height throughout the day.

How Tall Should a 12 Year Old Be? We can only speak to national average heights here in North America, whereby, a 12 year old girl would be between 137 cm to 162 cm tall (4-1/2 to 5-1/3 feet). A 12 year old boy should be between 137 cm to 160 cm tall (4-1/2 to 5-1/4 feet).
For example, studies in Australia found that boys are typically around one per cent taller than their fathers, and girls around three per cent taller than their mothers.
The short answer is that, on average, people keep getting taller until puberty stops, around 15 or 16 years old. By the time someone has reached their adult height, the rest of their body will be done maturing too. By age 16, the body will usually have reached its full adult form — height included.

What can I do to become taller?

And while it's difficult to say just how much your child will grow during this time, you can count on most of it happening, for girls, between 10 and 14 years, and, for boys, between 12 and 16 years.
About 68% of the female population is between the height of 5ft 2 inches and 5ft 9 inches. So, any woman shorter than 4ft 10 inches is typically considered short, and taller than 6 ft is assumed to be tall. In a nutshell, if a woman is less than 5ft 3 inches tall, she is considered short.

A growth delay occurs when a child isn't growing at the normal rate for their age. The delay may be caused by an underlying health condition, such as growth hormone deficiency or hypothyroidism. In some cases, early treatment can help a child reach a normal or near-normal height.
Conclusions: Final height is influenced by both height and the age of onset of the PGS in normal maturing children. A normal but early puberty exerts a negative effect on final height. A delayed PGS exerts a positive effect on final height.
