How tall are 12 year olds

Until puberty, most children grow around two or three inches per year. Boys hit puberty and their largest growth spurt between years of age, while girls hit their growth spurt about two years earlier.

During this massive growth spurt, most children grow a total of 9 to 11 inches. Your child's shorter or taller stature could be due to hitting puberty and this pivotal growth spurt earlier or later than her peers. Take your family history into consideration. If you or your spouse hit puberty earlier or later than your peers, it is likely that your child will, too. Around this age, it is normal for children to become aware of and sensitive to body image issues, so encourage your child to develop a healthy self image by talking openly about development and family history.

Pediatricians use clinical height and weight growth charts to determine whether a child's growth is normal given age, family and medical history. These growth charts show that the normal height for year-old children can be from 54 to 65 inches.

If your doctor finds a problem — such as a growth rate that had been normal but has recently slowed — he or she may track growth carefully over several months to see if the pattern suggests a possible health problem or is just a variation of normal.

If it's found that your child is growing or developing too slowly, the doctor may order tests to check for medical conditions such as hypothyroidism , growth hormone deficiency, or other things that can affect growth.
