Normal growth

What is considered a normal growth rate?

Growth not only involves length and weight of a body, but also includes internal growth and development. A child's brain will grow the most during the first five years of life, reaching 90 percent of its final size. Growth also affects different parts of the body at different rates; the head reaches almost its entire size by age 1. Throughout childhood, a child's body becomes more proportional to other parts of his/her body. Growth is complete between the ages of 16 and 18, at which time the growing ends of bones fuse.

Normal growth is categorized in a range used by pediatricians to gauge how a child is growing. The following are some average ranges of weight and height, based on growth charts developed by the Centers for Disease Control and Prevention (CDC):

Age Height - Females Height - Males Weight - Females Weight - Males 
1 27 to 31 inches 28 to 32 inches 15 to 20 pounds 17 to 21 pounds
2 31.5 to 36 inches 32 to 37 inches 22 to 32 pounds 24 to 34 pounds
3 34.5 to 40 inches 35.5 to 40.5 inches 26 to 38 pounds 26 to 38 pounds
4 37 to 42.5 inches 37.5 to 43 inches 28 to 44 pounds 30 to 44 pounds
6 42 to 49 inches 42 to 49 inches 36 to 60 pounds 36 to 60 pounds
8 47 to 54 inches 47 to 54 inches 44 to 80 pounds 46 to 78 pounds
10 50 to 59 inches  50.5 to 59 inches 54 to 106 pounds 54 to 102 pounds
12 55 to 64 inches 54 to 63.5 inches 68 to 136 pounds 66 to 130 pounds 
14 59 to 67.5 inches 59 to 69.5 inches 84 to 160 pounds 84 to 160 pounds
16 60 to 68 inches 63 to 73 inches 94 to 172 pounds 104 to 186 pounds 
18 60 to 68.5 inches  65 to 74 inches 100 to 178 pounds 116 to 202 pounds

Although a child may be growing, his/her growth pattern may deviate from the normal. Ultimately, the child should grow to normal height by adulthood. If you suspect your child or adolescent is not growing properly, always consult your child's physician.
