Child Height and Weight Chart

Humans come in all sizes, height, weight and body type whenever you look at any gathering of people, children or adults. But given this natural variations, how do you know whether your children are growing normally or not? What are the possible signs and symptoms if something is not right, and when should you be worried? Read on to find out more.

Average Child Height and Weight Chart at Different Ages

All children grow at different rates. Growth rates depend on many individual aspects of a child's life, including both genetic and environmental factors. To help determine whether a child is growing at an average rate in both height and weight, pediatricians refer to height and weight charts for children at a particular age. Here are the average child height and weight chart at different ages.

How Can I Tell If My Child Is Overweight?

To compare children to others in their age range, doctors use body mass index (BMI) and percentiles. The BMI figure indicates how your weight compares with your height, giving an approximate indication of whether you are over- or under-weight. The BMI is calculated using the following equation:

BMI = Weight/Height­­­2

After BMI is calculated for children and teens, it is expressed as a percentile which can be obtained from either a graph or a percentile calculator. Because weight and height change during growth and development, as does their relation to body fatness, a child’s BMI must be interpreted relative to other children of the same sex and age.

For instance, a boy in the 40th height percentile will be taller than 40% of other boys at his age. A girl in the 70th weight percentile will be heavier than 70% of girls her age.

Generally speaking, the higher your BMI above the normal range, the more overweight you are. However, BMI is only an approximation, and does not take into account muscle mass or natural body shape variation.

The BMI-for-age percentile growth charts are the most commonly used indicator to measure the size and growth patterns of children and teens in the United States. BMI-for-age weight status categories and the corresponding percentiles were based on expert committee recommendations and are shown in the following table.

Weight Status Category

Percentile Range

Underweight

Less than the 5th percentile

Normal or Healthy Weight

5th percentile to less than the 85th percentile

Overweight

85th to less than the 95th percentile

Obese

Equal to or greater than the 95th percentile

Nevertheless, there are some changes in growth patterns that may indicate an underlying issue, so will require further investigation:

However, it’s important to remember the unusual growth patterns on the child height and weight chart are only an indication of possible issues. Medical professionals will be able to assess if there is a real medical condition, or whether your kid’s growth just requires careful monitoring.
