# What Is The Average Height For 6 Year Old Boy And 8 Year Old Girl ?

The average height for a 6 year old boy is 42 inches. For an 8 year old girl the height is 45 inches.

• Six year old boys should be around 42 inches in height and 46.2 pounds according to medical professionals.
Height is a genetic factor. This is why there are many different heights even in one family. One person can be well over six feet, but their sibling can be extremely short. Males will usually be taller than females, so this is yet another factor that may come into play with height.

Usually tall parents will have a tall child, but this is not always true. Since genetics is a factor, if the short gene is recessive but occurs in both parents a child may be on the shorter side. Likewise, short parents can have a tall child. The best example of this is the television documentary Little People, showing a couple can have an average sized child, even though both parents are on the short side.

• An 8 year old girl is usually 45 inches and weighs 57.2 pounds.
As with boys, females can vary in height from their parents and siblings. There can be some really tall girls, those over 6'0", yet most females tend to be around 5' to 5'8" at adult heights. Many factors can contribute to this and most of it is who the person takes after genetically. For example, a family with a short grandmother may still have average height children, but her height can be seen in the next generation. For scientists interested in genetics, looking back over several generations can be interesting to see how height has played a factor in a family given that height is variable.
