What Is The Average Height Of A 12-Year-Old?

Know What to Expect and When to Visit the Doctor

It is normal to be concerned if you see that your child’s height is significantly different from his peers. It is normal for your child’s height to be different from the average. The average height for 12-year-olds for girls and boys is 59 inches. Your child’s growth rate and height are affected by puberty, medical conditions and family history.

Growing and Puberty

What is the height of a two-year-old child?

Most children will grow two to three inches per annum until puberty. The puberty of boys and the largest growth spurt occur between 10-16, while that of girls occurs two years earlier. Most children will grow 9 to 11 inches during this huge growth spurt. If your child is shorter or taller than other children, it could be because she has reached puberty earlier or later. Consider your family’s history. Your child may also experience puberty sooner or later than their peers if you or your partner hit puberty before or after your peers. It is common for children of this age to be sensitive and aware of body image issues. Encourage your child to have a positive self-image by discussing their development and family history.

What Is The Average Height Of A 12-Year-Old?

Normal is relative

Pediatricians use growth charts for height and weight to determine if a child is growing normally, given their age, medical history and family background. The growth charts indicate that a child’s height at 12 years old can range from 54 to 65 inches. When a child’s growth chart suddenly changes or if the percentiles are much higher or lower than they were in the past, the doctors start to take note and investigate the cause. Your child’s height has probably always been in the 10th percentile. This is completely normal. If your child used to be in the 65th percentile but has now dropped to the 10th percentile, this could cause concern.

When to Consult a Doctor

The weight range for a two-year-old

It is time to see the doctor if your child grows less than 2 inches per year, experiences rapid weight gain or loss, or has frequent infections. Your child’s doctor will perform a physical exam to rule out thyroid, heart, or lung problems, as well as autoimmune conditions, malnutrition and other concerns. Growth hormone treatment can increase a child’s height up to 3 inches by adulthood if they are diagnosed with growth hormone deficiency. When children are healthy, a clean health report should put you at ease.
