Having a height and weight age chart for kids is an essential part of monitoring your infant's or child's health. It helps you get insight into whether your baby's growth is average. If the growth is not ideal, you can get a doctor's consultation at the right time and know the cause behind it.

This can also help you understand what measures you can take to bring the growth to the normal range, if possible. If not, then you can know what you can do to ensure that there are no complications in their health. One of the primary symptoms of a growth problem is when the child's yearly growth is less than 2 inches after they are three years old [1].

Checking the right height and weight chart by age can also help bring to notice any health conditions that may be otherwise overlooked. More often than not, abnormal weight and height growth is a result of improper nutrition. However, there are instances where improper nutrition may be a result of a health condition. Getting a diagnosis before such a health condition progresses can help keep your child healthy.

Given its importance, it is imperative that you refer to the correct height weight age chart for kids. While you may want to refer to the chart provided by WHO, you may find the chart provided by the Indian Academy of Pediatricians (IAP) to be more useful. Read on to find out the ideal height weight age chart for kids and why referring to the IAP chart is essential.

Why use the height weight age chart for kids by IAP? 

Pediatricians in India advise parents to use the chart provided by IAP because the growth of Indian children is not similar to other nations' children. This difference occurs due to the different nutrition and environment of India. Apart from that, the growth of a child is majorly dependent the genetics and family history. As a result, Indian parents should refer to this chart for their child's development. 

The ideal growth of your child is dependent on various factors such as genetics, family history, and gender. Among these, one of the important factors is the weight and height of the baby at the time of birth. Keep these factors in mind while using a height, age, and weight chart.

When to measure the height and weight of your child?  

Ideally, the measuring frequency of your child's height and weight vary as they grow up. This is because of the biological changes that their body goes through. Generally, as the child grows up, the frequency of measurement should decrease.

Ideal intervals of measurement are monthly until the child turns one and thereafter every two months until the age of 2. You should measure every three months until your child reaches the age of six. After this age, you can reduce the frequency and continue up to the age of 18. It is important to ensure that you measure them in reference to an updated height, weight, and age chart for kids.
